    Hey. Some info from us. Please note this is an info for a full catalog of our games (88 titles in total, 5 new games added in 2019). Browser Html5 games - we (team of 5) make a living out of it. Some licenses, some b2b deals, some ads. Facebook Instant Games - was super nice in 2018. In 2019 our reveue from games (old and new) is rather small. Still makes a little sense to publish new games there. Mobile games - zero. null. nada. Not a single dollar.

    Is Panda 2 Dead?

    Hi all, I just wanted to let you know that Panda is still my primary game engine and I have no plans to abandon Panda. The absence of @enpu is unfortunate but don't forget that Panda is open source so most of the time, it is possible to fix minor issues yourself by having a look in the source code. Currently I have two large commercial projects powered by Panda and it is expected that these project will be running for at least several years. Don't forget that Panda by itself is a great engine and that it has a couple of features that not all other engines currently are supporting. Take hires support and the custom Panda GUI for example, these are just great! I will continue to read this forum on a regular basis. If there are questions that I can answer quickly, you can count on my support. Stephan

    Everything to create fb instant game

    I'll have a stab at these as I like to snapshot my view on things periodically ... Yes and yes. Pixi has a very decent power to size ratio and solid compatibility (v4.8 may be wisest in 2019?). For a competent developer capable of spinning their own game structure Pixi is ideal for a lightweight browser game. Coming in at less than 5MB total for your IG is wisest. Red tape aside, it's possible but improbable to make money releasing a single game. Primary monetisation choice with FB IG is in-game ads (which are a low value transaction for a developer and an intrusion to the player). In-game purchases have more value but will require significant retention first. Or consider indirect value generation such as consultancy services, brand building, learning for the next game? FB IG is inherently multiplayer (async). Within the SDK are context (group) leaderboards, notifications, packet sharing (challenges). That being said the vast majority of initial plays will be in solo mode, so a compelling single player experience is necessary for retention. Get creative for the crossover! For more advanced multiplayer use a custom backend. Having some separation / abstraction from the Facebook SDK might be wise in case other markets are a better fit for your game? For Multiplayer specifically? Yes there's a TicTacToe example that covers the basics of a client-server model. My advice is play some of the popular titles, understand what the FB IG audience seem to be attracted to and how other developers are leveraging the SDK to create retention and monetisation - warning, some of it can be ugly. Iterative development is going to be crucial, however you'll likely only be promoted once - so use it wisely, and use each territory to run a split test. Or build several games and apply the learning from one to the next etc. If you haven't built dozens of games already, FB IG probably isn't for you yet? Imo there are better platforms that can help evolve game development skills and player retention mechanics. Instead see FB IG as a specific audience with a specific style of game - developing a game precisely for that might work out very well (FB has a HUGE potential audience after all). Imo Messenger games should be about decorating a conversation, in the same way filters decorate a photo. So quick, contextual, personalised, fun, indisposable. That's not necessarily a standard casual game, so changing some assumptions and expectations may be wise. Just my advice, your mileage might vary!

    bugfix for Panda2 p2 plugin

    Yeah i'm still here! Just been a bit busy lately, but i am working on Panda 2!
  9. 3 points
    Hello, My goal is to update a small part of a texture the fastest way possible with WebGL2, preferably using Pixi.js v5 (RC 3 is out). Am I right that a RenderTexture is going to re-upload the whole texture whenever there is a change? (this would not be good for a big texture, hence why I am looking for another method) I'm a complete noob when it comes to OpenGL, but I've googled a bit and figured that I can use gl.texSubImage2D() to upload just the part of the texture that I need to change. I didn't find a way to get the WebGLTexture object of a PIXI.Texture, so to be able to use that command I did something like this (not the complete code): renderer.addSystem(PIXI.systems.TextureSystem) renderer.TextureSystem.contextChange() // needed to do this loader.load(main) // and could not use gl.texSubImage2D() on tex before the loader called main function main() { let tex = resources['test'].texture let imgData = new Uint8Array(32*32*4) renderer.TextureSystem.bind(tex) renderer.gl.texSubImage2D(gl.TEXTURE_2D, 0, 0, 0, 32, 32, gl.RGBA, gl.UNSIGNED_BYTE, imgData) renderer.TextureSystem.unbind(tex) } But I wish that I had the WebGLTexture available so I could avoid messing around with PIXI.systems.TextureSystem, because I don't really know much about it or when and how it should be used. I also want to read the previous data and change it, I figured it can be done with: gl.readPixels(0, 0, 32, 32, gl.RGBA, gl.UNSIGNED_BYTE, imgData) But that needs the frameBuffer to be binded first... Hence I tried to also use the PIXI.systems.FramebufferSystem, lol: renderer.framebufferSystem.bind(fb) //fb = new PIXI.Framebuffer(tex.width, tex.height).addColorTexture(0,tex) gl.readPixels(0, 0, 32, 32, gl.RGBA, gl.UNSIGNED_BYTE, imgData) But it was not that easy, I didn't even find a way to unbind it. But I guess it is not supposed to be used for my little problem...? Maybe there should be some Pixi.js functions to do this? Maybe something similar to this: texture.getPixels(x, y, width, height, ArrayBuffer) texture.setPixels(x, y, width, height, ArrayBuffer) I'm new here btw, this is my first post I don't have much Pixi.js experience yet, but I really like it.

    No bans are happening here (yet). @5neia_opo2@google-mail.ooo, try to understand the frustration people are experiencing. A new user came to the forum and in nearly every post they made trashed the project they were asking about. A lot of people here put in a lot of time and effort to not only to develop the project, but answer questions here as well. I was definitely frustrated reading your responses as someone who has put 6+ years of their life into this project. @botmaster did a poor job of handling that situation, but has apologized and I'm sure will do better in the future, as will you as well. Let's all be adults about this, acknowledge we did something wrong, and move on. @5neia_opo2@google-mail.ooo you are free to ask any question you need help with, but I definitely recommend reading through some tutorials, the examples, and checking the API docs before asking questions. It will often lead to you finding the answer yourself, and there will be less fatigue for the people answering here on the forum. I'd also recommend you approach things you don't understand, or decisions you disagree with, with a more open mind. Try to learn and grow the new library, not all libraries are alike and different problem spaces call for different solutions. Having a bad attitude is a good way to earn ill-will in the community and you may no longer get the help you expect if you are ungracious about it. When you find inconsistencies, or things you think should work differently, then change it! Pixi.js is an open source library built by the community. Everyone gets a chance to make the library better by contributing to it. The best way to get problems you have fixed, are to fix them yourself.

    @Danidre as far as he accepts to iframe your game (and its source code is uglyfied and minified).. but I think you would be better off if you're selling non-exclusive licenses of your game. That would be more profitable to you. If you prefer to earn revenue share from ads, its better to you to distribute your game through the big distribution networks, because they potentially will put your game in many portals. But bear in mind that: 1 - selling non-exclusive licenses is better for you as well as to whole game developers community because it will keep the price of games at a healthy level (I'm considering you wouldn't sell your game for very low price. It would lower median prices of the games). 2 - revenue share is a way of devaluate the game development market. Why will someone pay say $500 for a game if he/she can have thousands of games literally for free? For free? Yes, for free. Ads revenue will be paid only if your game was played and generated enough money to split you may earn something. Otherwise, you loose money. Why should you take the risk? You did what was your role: developed the game. You already invested time and money making it and also took your share of risk. Which risk? The risk no one wanted to buy it so you would have to start from zero to develop a new game on your own expenses. Those who liked your game should invest the money by licensing it and take the risk themselves. If the game were a flop or a success, is the risk portals have to take. 3 - No one can assure you that your game will have millions of game plays. No one. Neither distribution networks nor single site owners. If someone assure it to you, he/she is lying to you. 4 - Even if your game make little money with revenue ads it doesn't mean you will receive it. The revenue share deals always have NET30, NET60, NET90 and a minimum payout. Even though there are cases that late payments happen. Think about it: if someone was sure he/she would make a lot of money from your game, why would they share it with you? Does he / she have a charitable soul? Who makes the money with revenue share? Distribution networks make the most money. In second place, portal owners (portal owners may not earn anything but they also don't loose a cent). Are they wrong? No, they're not. They're making a living. We, game developers, are wrong by accepting practices that devaluate us. I'm seeing HTML5 game developers doing the same mistakes Flash game developers made in the past. In the finals years of Flash it was too hard to make money with games because Flash developers themselves devaluated their market. At the end, it's in your hands to decide what's better for you. Regards.

    if canvas is gpu-accelerated, you can see those operations in NVidia NView. Also, 5-6 years ago, people compared drawImage vs fillRect/pattern. I think that it also has to be different in case your sprite is axis-aligned or not, analytical antialiasing should affect those things.

    Ropes Game

    @AlienBurn recommend you try both and see which one suits you. For me Panda -Easy to learn, I have three games made with panda. -Very small community. -Panda Editor is not free but it can make you code your game faster(export to web or mobile is easy). -Growth So Slow, Engine has not updated for a long time, I worried that it like impact.js. Phaser -Much tutorial and Demo Example (but it left me quite confused after looking at multiple tutorials and even trying a few test projects.) -Very large community. -if you want to export to mobile and Code obfuscation, You need to learn cordova/phonegap , Webpack etc….it's totally free -Engine keep updated each month, fast-growing. Finally, Both of them are an awesome HTML5 engine.😁

    How many webworkers to create?

    I don't know any link that explains this directly. But web workers are not part of javascript. Web workers are a browser feature that you can interact via javascript. This means that when you want to process your code in the background, you tell your browser using a javascript api to do your work and pass back the result in the end. This background process works the same way as any background thread your browser executes. If you execute 100 web workers, the browser will use its web worker pool to execute your workers, the pool may have 10, 20, ?? threads, but probably not 100.

    Hello guys and basically this topic is for you guys/developers that upload games on gamedistribution so, I read too many topics with gamedistribution and all you guys/developers that you read all bad comments, "gamedistribution not pay me yet", "gamedistribution this, that" but you still continue upload to this website and support it? Serious? And the funny is, upload too many games to get in 1-3 or more months ........ What/How earning? 50euros? Or less? They own complete chain in advertising. So officially you get 1/3 of the income of a game. But they get often 2/3 because 1/3 for gamedistribution but also 1/3 since they own big game portals like Kizi. But also: You get 1/3 of the net income. But the ads are sold by their own advertising company so they can control different between Gross and Net. So they get up to 70% and you get 15% ............ if you are lucky! My experience to them? -> Of course. I get ~100euros in 6months from 10+ games... And when i remove all and i upload to other portal, i get ~200euros in 1 month from 2 games only. Imagine how % you get from your games. Even your game is addictive, even is top of the top....... You still lose a lot money. So you can continue upload your games, no problem. And open topics again or post to ask for help. Send them unlimited emails, will answer when they want. Cheers. By the way, @GameDistribution Support I'm still waiting "success stories" ? Can you share some original-success stories? Remember? I post under your post in this topic (June 18): P.S 1: Why open this topic ? -> One (1) only answer : To help new developers and their games. I learn from my mistakes. Bad experience with this company and similar. So i share true stories, that's all. P.S 2: How know and share all this ? -> This is personal sorry but thanks to a friend, he knows. P.S 3: Am i wrong? -> As i said, no problem, you can still continue upload your games. Your results from your earnings is the only truth.

    I am making UI Components Framework for Phaser 3, that is driven by JSFL-generated jsons and atlases. It means that you can build your UI in Abode Animate, export it with given script, and forget about manual code positioning and building stuff! Please, try it out. https://xense.github.io/phaser-ui-comps-docs/tutorial-showcase.html Docs, examples, tutorials: https://xense.github.io/phaser-ui-comps-docs There are two basic things in this framework. First is ComponentClip, which is a view instance, it is recursively self-build by provided json and atlases. Second is UIComponentPrototype, which is clip controller. It can be easily extended to create any components, windows or whatever you need. Essential meaninig of it is that it doesn't need a clip to exist always. For example, you can change states of a root clip, and child clip can get new clip instances, ore lose them, and nothing bad happen. Some base components are already included UIButton has 4 states, "up", "over", "down", "disable" UIButtonSelect same as button, but behaves like checkbox, has 8 states, by adding "_select" suffix to UIButton's states when selected. UIButtonRadio Selectable buttons, that can be grouped to select only one of them. UIButtonDraggable same as UIButton, but also emits drag event, drag bounds can be self externally. UIScrollBar vertical or horisontal bar with draggable thumb and prev/next buttons. UIProgressBar Setup only start and end elements positions, scale, rotation or alpha, and this component will interpolate them according to provided progress value. UIScrollPanel Helper for scrolling any element with UIScrollBar. UIContainer Base container component to add other dynamically created components inside. Can be easily extended to create any types of lists, for example. I'm still working on new components and extending existing functionality. Tell me, would you use it, what other components you may need, and whatever you think about it. Any feedback is appreciated! Also I'll be thankful for any collaboration. Available at GitHub and npm

    One thing you may want to try and do is some more research regarding tile map engines. There are probably some GitHub repos for some. This way you can better learn how others are doing it. I have built tile map and scrollers a while back. The engine core itself was very different, since the engine was C++/OpenGL and specialized to handle it. Whereas in your case, you're using an existing engine and its methods to draw. If you are still truly destroying/creating 500 sprites per frame, you should rewrite your algo now. You definitely want to have a sprite pool you render from. Think of the problem as paging in 1-2 rows or columns. For most cases, those are your deltas. Take the simplified case of moving in the X axis. In this case, as you move to the right, for example, you will eventually hit the point where you will need to page in a column to the right. You can achieve this by simply grabbing the leftmost column and rebinding the texture (no destruction or creation) and updating positioning. Note at this moment I'm ignoring z order. The trick here is your overall tile area needs to be larger than your viewport so one doesn't see either side pop in or out. Now much overdraw will be dependent on individual tile size and the max speed you need to scroll through your map. Your "worse case" will be 2 dimension movement where it triggers both row and column swapping. However if you think about the problem more. You are no longer modifying 500 sprites. Rather in your case, about 150 sprites. Note in your code, you do far more than 500 sprites, you're doing 1250 sprites, but for consistency I'll use 500 as the high end number. This means that for the 350 other sprites, they should be "correct" and don't need adjustment. Now you have to address z order. You could opt to re-build z-order each round. The problem area really are when you need to insert versus append/push, since depending on implementation, that will move memory (unless it's a linked list ... I have't looked at the code). If it is a linked list, then it should be relatively cheap, but based on Ivan's comment, it sounds like it is not. One partial "cheat" you could do for draw order too is to have layer containers in your master container, and use that for your z. Note you'll still need to sort that. The other thing is clever art usage can minimize how much sorting is needed. A thing to look out for is how non-world objects interact. So, for example, if characters can look like they are "behind"/occluded by tiles, you need to have a method to control that draw order. In short: - Look for other tile engines and see if you can find some code to study. You want approach, engine type doesn't matter so much. You need to understand the basics of that type of engine more. - Don't destroy/create per frame. Reuse. In general this is a good rule. If you find yourself creating and destroying objects a lot during normal runtime, you should scrutinize your technique. This is not to say you never can do it. I do have some games where I actually create and destroy on the fly but it is for a handful of objects on a custom C++ engine. - Embrace object management. This is the unfortunate responsibility of the game dev. Sure you want to try and avoid it when possible, but world management ... in particular ones which incorporate a lot of animating visuals need to be managed.

    Why did the forums move?

    When I go to the Discourse site, I just see a list of messages. It doesn't look anything like this site. I guess I will have to make a fake username, and join, if that is where everyone is going. I can never fool these sites. Later some site will ask me "Vornay, do you know someone named <insert my real name>???", and I'm like, "No man, never heard of them." I guess if Phaser doesn't want to run a message board, that is the real issue. Having to moderate it probably distracts from working on Phaser. That is too bad. Social media is pretty toxic nowadays, with everyone apparently being either a Communist or a Nazi. If you get called a Nazi, these larger platforms will simply ban you. If one bans you, the others may ban you too. Your investment in their platform gets nullified. That is why I don't use Unity, Unreal, or other non-free engines. That is why I don't want to be dependent on the App Store or Play Store. That is why I don't work in Swift in anymore. One person gets a wild hair up their butt, and you lose everything. You find out your castle was built on their land, and you never really had a castle. That is why I wont use those forums. They are the opposite of free.

    I am not sure on Discourse policy of sharing data with 3rd party, but you can't really escape tracking. Most websites use Google Analytics. Your best bet is probably using Firefox with disabled tracking, using throwaway email for each service, (+ KeePass so you do not have to remember) and VPN.

    This is a really tricky question for a generic answer as there are so many variables which _could_ dictate whether your project structure works well or not so well. Personally, I'd take any answers with a pinch of salt i.e. there is no single 'best' structure, like, not at all. Have a think about what the problems you are trying to solve are and how the processes and concepts you employ for organisation are going to solve that problem? To the above question, the answer is usually 'I do not know'. This is fine. With the above in mind it is usually better to follow this sort of process: Start the project. Put stuff anywhere, it does not matter at this stage. Get something working. Keep going. Now you have a working product and you can start to identify what organisational problems you have and think about how to solve them. Until this point you are largely guessing. If you have created several similar projects before your guesses are probably good, if not, then they might not be. It is relatively easy to apply some structure and organisation to a project that doesn't really have one, it can be pretty tricky to change organisational structure (can be, depends on many things again, you certainly should not be afraid to change later on if your current system turns out to be not very efficient). There are some rules of thumb that might help you though: Small files and folders are easier to manage than larger ones i.e. small in scope, not necessarily small in lines of code. Decouple things as much as possible, this makes them easier to work with, and makes organisation easier to change. Tight coupling is a nightmare, avoid at all costs. Uber objects (and, similarly, uber-projects) are hard to manage, this is really the above concern worded differently. Divide and conquer. UI and logic (rendering and smarts) are good things to separate. Avoid logic duplication, if you end up writing similar logic in multiple places, consider generalising and abstracting it. Utility functions can form a huge part of your codebase and is _usually_ a sign of good organisation. MVC is fine for games. As are other methodologies. Go with what you think makes most sense for you (and your team) and the project.

    Pixi.Mesh gl_FragColor Alpha Channel

    Hi, I've tried to change the Alpha Channel on gl_FragColor on a Mesh, but it doesn't show a result as I expect. For example, on the pixijs.io example ( https://pixijs.io/examples/#/mesh/triangle-color.js ) void main() { gl_FragColor = vec4(vColor, 1.0); } If we changed the line into void main() { gl_FragColor = vec4(vColor, 0.5); } It doesn't show any difference. Is there any workaround/settings I need to adjust to use the alpha channel correctly? Thanks.
  34. 2 points
    void main() { gl_FragColor = vec4(vColor, 1.0) * 0.5; } We use premultiplied alpha everywhere. Instead of (r,g,b,a) we store (r*a, g*a, b*a, a)

    Redrawing only when needed?

    I have a method where I have two different changes that can happen in the scene. Tweens and handlers that get run every frame. For tweens I check if amount of active tweens creater than 0, then it means that something is changing. For onrender-handlers I have a custom component that allows for components to register themselves to get onrender -events and their return value will tell if something has updated. If either tween has updated or any of the components requires rendertime, then that frame is rendered. Otherwise no render will occur. In some cases this can be improved by splitting the scene into multiple canvases. One that gets updates rarely and one that holds the actual gameplay and is updated frequently. Though using that method is something that should be clearly thought out beforehand or you'll end up with multiple canvases to render each frame. Having render loop stop completely is something that you shouldn't do. As calling requestanimationframe is really cheap and not worth the trouble to build a mechanic with renderloop cancellation. Easier to just skip rendering on frames that dont need it.

    its not an edge case, sometimes just one resource can fail, depends on what server or service do you use. If its a problem for your users, make a fallback, for example you can start downloading everything again

    ctx.clearRect() not working with Image.

    @James432213 hi, many issues here, all solvable. 1) The function named "canvas" rename this and avoid some confusion, call it "init" or similar 2) doKeyDown function has parameter "e" but references "event" in the switch - be consistent. 3) the functions doKeyDown, updateCanvas, drawPlayer are scoped "above" the "init" function, so they can have no easy reference to the "canvas" variable defined within "init". Notice also the name collision of "canvas" if we ignore step 1. Easy fix is to move these function declarations inside the "init" function. 4) There's nothing wrong with ctx.clearRect Some basics in how to debug your code will be beneficial, in particular the developer console (F12) is great, and using "console.log" can send helpful messages there from your code. Use that as a start towards watching the flow of your code when it runs, and where things are not actually working as might be expected on a first draft of code. This will lead to more advanced debugging techniques and more elaborate (and working) code.

    Do you draw something else than the video to canvas? If something taints a canvas then it stays tainted no matter what is rendered in the future. Or it might be due to stream becoming unavailable at some point for short duration and that could cause tainting (though the bug report I found on this should be already resolved, it was 5 years ago). Pretty sure it's some kind of edge case in security constraints which causes canvas to become tainted (by something), which causes security error when pixels are read from it.

    I hate designing levels!

    Procedural generation can be a load of fun, but its a butt-ton of work to get working well. You could even use a genetic algorithm (GA) to create levels, have an automated actor play them, test the 'success' of the actor using fitness functions and then loop that process until you get levels (again, based on a heuristic function) that are fun to play. The up-shoot is that you can, potentially, create a near infinite number of levels like this. Or at least generate a manageable amount (say, 30) and manually curate them. Depending on how good your heuristics are you can create levels that are harder or easier for humans to play. It's a ton of work though. So depends on your mindset. Some crazy people find that a wonderful coding challenge.

    there is no public property available but you could use the following private property timer._pause working example: var timer = game.Timer.add(1000, function() { sprite.remove(); }); if(timer._pause){ console.log("paused") } else{ console.log("Not paused") }

    I've got a situation my physics simulation is running at high framerate (60fps), but some devices my app runs on cannot run the graphics (PIXI) at 60fps without causing the physics simulation to stutter and jump, causing undesired artifacts. So, in pursuit of performance, I shoved the physics simulator (in my case, matter.js) into a web worker, but then still found that some devices couldn't handle updates at 60fps in the main thread. So I started setting an interval to apply updates from the simulation to PIXI at a fixed rate - 30 fps to start. However, sometimes even on some devices that was unsustainable. So, the question came down to - what FPS *should* my app run at? And when I say "run", I'm talking about changing the position of PIXI objects base on updates from the physics simulation, not about changing the speed of the PIXI's ticker. Since the speed at which I could apply updates from the physics simulation and still achieve sustainable render speeds without lagging varied from device to device, I decided the best way to decide on the FPS to run at would be ... let the app itself decide at run time. So instead of coding a fixed FPS, or giving the user a slider to adjust, I let my app measure and adjust it's FPS based on what it measures as sustainable while it's running. Enter my solution for my app, FpsAutoTuner: https://gist.github.com/josiahbryan/c4716f7c9f051d7c084b1536bc8240a0 - contributed here to the community in case it may help someone else solve a similar problem. It's framework-agnostic, no external dependencies, written as an ES6 class, but could easily be rewritten as a ES5 if you wanted. FpsAutoTuner works by measuring the FPS (which you tell it by calling `countFrame()`) and then every so often (at `tuningInteval`ms), it compares that measured FPS to the `fpsTarget`. When the measured FPS goes below `fpsTarget` less `tuningMargin`, the `fpsTarget` will be decreased by `tuningRate` and the `callback` will be execute with the new `fpsTarget`. Likewise, when the measured FPS exceeds `fpsTarget` less `tuningMargin`, then `fpsTarget` will be increased by `tuningRate` and `callback` will be called with the new target. Example usage: // Somewhere at the top of your file import { FpsAutoTuner } from './FpsAutoTuner'; // Then later in your code, probably in your constructor of your game object this.fpsAutoTuner = new FpsAutoTuner({ fsTarget: 30 callback: fps => this.setFpsTarget(fps) }); This assumes that you have a function called `setFpsTarget()` on your class, probably that does something like this: // This is just an example method, on your own class... setFpsTarget(fps) { clearInterval(this._fpsTid); this._fpsTid = setInterval(this._render, 1000 / fps); } Then later in the rendering portion of your code: // inside the render loop of your code, call: this.fpsAutoTuner.countFrame(); That's it! Your app will now automatically adjust it's FPS as needed when it detects lower/higher frame rates available. (FpsAutoTuner automatically starts it's auto-tuning timer in it's constructor.) There are plenty of options you can pass to FpsAutoTuner to tweak it - they are all documented at the top of the gist. Specifically of interest, you can set `tuningInterval` (default 5000ms) to change how often it measures/changes the FPS. This all has just been a humble attempt to give back to the community. Use and enjoy. Contributions/changes/suggestions to the gist are welcome! Download FpsAutoTuner from GitHub here.

    I could not choose what to study for coding games and I decided to study these tools: Pure WebGL 1.0 and pure WebGL 2.0. I like to study linear math, trigonometry, shader math. I like to study this book which uses pure WebGL and glMatrix: Build your own 2D Game Engine and Create Great Web Games I want to understand how game frameworks works under hood, I mean: Pixi.js, Phaser.js, Three.js, Babylon.js and so on. I like to write very simple clone games like: Snake, Pong, Tetris and so on without game frameworks and game engines. I can use C++ books about OpenGL to study WebGL because WebGL 1.0 is based on OpenGL ES 2.0 (WebGL 2.0 on OpenGL ES 3.0). There are a lot of books and examples in C++ and GLSL that I can translate to WebGL. I can use ThinMatrix video tutorial to study OpenGL using Java and translate his examples to WebGL. I study C# for Unity Game Engine and I write my own simple game engine in C# and OpenGL 3.1 (OpenTK) by rewriting example from this books from deprecated/legacy OpenGL to modern OpenGL: C# Game Programming: For Serious Game Creation This book is a great. It study how to write a good modular architecture and how to develop software using TDD (Test-Driven Development). I like TDD and BDD (Behaviour-Driven Development). I am a fan of these methodologies of software development. I want to rewrite the code from this book to TypeScript/WebGL because TypeScript is very similar to C#. I liked compiled languages like C# and Java. But I study JavaScript 5 (2009) because it is very popular and I will be able to find removed jobs like freelance in the future when I will be a skilled computer graphics and game programmer. Pixi.js and Phaser.js for 2D games. It is very popular frameworks. A lot of works was made. You can write your own shaders in GLSL for these frameworks. Three.js and Babylon.js for 3D games in interactive 3D applications. These are 3D libraries based on WebGL and Canvas API like another popular graphics libraries. You can write shaders for this graphics libraries in GLSL too. Unity Game Engine for 2D and 3D games. I can write WebGL games for Desktop and I can build them for Android, iOS, Desktop (Mac, Window, Linux) to native applications and these native applications will not have browser restrictions. I can write shaders in HLSL and this shader language in very similar to GLSL. I can connect my WebGL, desktop and mobile clients to Node.js server that your Socket.io or WebSockets. For WebGL version I can use pure WebGL frameworks because Unity WebGL build does not work on mobile devices P.S. Sorry for my English. I study it but it is very hard. I did not use Translate Google for writing this message, I wrote this myself.

    Thanks @NoxBrutalis I was focusing to much on the .createMultiple() method. Simply creating the coins in a loop and then adding them to the group worked for me this.gameitems = this.physics.add.group(); for (var i = 0; i < 20; i++) { var x = Phaser.Math.RND.between(0, 800); var y = Phaser.Math.RND.between(0, 600); var newobj = this.gameitems.create(x, y, 'sprites', 'coin1'); } Btw is there a way to get the width and height values (800 and 600) from the current scene or game instead of using hardcoded numbers for the RND function?

    Sounds like what you need is to have a sprite child for that graphics object. You see, technically, the entire canvas (whether 2d or webgl, doesn't matter) is one big image. PIXI just draws different parts of the image separately to create the whole. So when you render a container, you will draw each child of that container (whether sprites, graphics, or something else) and all of its descendants (children, children of children, etc) in order from top (root) to bottom (leaves). The different parts may overlap, but at the end of the day the entire tree is reduced to an image. So do you want an image loaded from file to be in the middle of your graphics object? Easy. Just position the image object (sprite) so that it is in the middle of your graphics object. The easiest way to do that is to make the sprite a child of the graphics object, so that its position (x and y coordinates) are relative to the top-left corner of the graphics object. Parent/child relationships are not required, mind you, it is just a convenient way to get relative positioning (and also guarantee that the child is drawn after the parent, possibly overlapping). Does the whole paradigm of drawing position and order make more sense now? With all that in mind, I'll answer each question specifically: 1) Is there a way of doing this, similar to the plain/vanilla canvas way: // untested// 2d or webgl, doesn't matter.var renderer = PIXI.autoDetectRenderer(300,300);var canvas = renderer.view;var stage = new PIXI.Container();var sprite = PIXI.Sprite.fromImage(source);var graphics = new PIXI.Graphics();stage.addChild(graphics);graphics.addChild(sprite);// assuming graphics object is 100w x 100h// graphics position is centered horizontally and vertically relative to stage/canvas.// absolute position of the graphics object is 100 points right and 100 points down from the top-left corner of container (parent).graphics.position = new PIXI.Point(100,100);// assuming sprite object is 50w x 50h// sprite position is centered horizontally and vertically relative to graphics object.// absolute position of the sprite object is 125 points right and 125 points down from the top-left corner of container (grandparent).sprite.position = new PIXI.Point(25,25);// draw some lines n stuff on the graphics object.// Only reason I'm putting it in the ticker is just in case the image hasn't loaded yet.// We'll render 60 frames per second until it does... and after it does!PIXI.ticker.shared.add(function () { renderer.render(stage);});// put the canvas somewhere in the DOM. 2) Is the context (2d), unique to the Canvas? Yes. 2d is a context. webgl is a context. PIXI calls the 2d context renderer "Canvas". Both contexts are built on a "canvas" dom element. Confusing? Yes. 3) Would drawing imaged[sic] to the graphics object limit me to the CanvasRenderer... No. PIXI abstracts the WebGL nonsense (it's pretty arcane) away from your eyes so that you can create sprite objects that can be rendered magically using webgl context or rendered boringly using 2d context.
