  1. Hello, I'm new to Javascript and PIXI I've been recently been working on a project using PIXIJS and need some help. I am trying to make a user interface with 8 buttons for the bounding box and 1 rotational button to scale, rotate and move my sprite. At the moment, I made each individual buttons of the bounding box an individual sprite and manually setting their interactive mode and coordinate and added them as a child to my main sprite. The issue with this method is that when I move one button, the other buttons don't move together to align with the transformation. Also, I
  2. Happy New Year everyone. To kick off 2021, I thought I would announce a little competition to submit the best PR in January to the open source PlayCanvas WebGL game engine! $1000 prize money. See the Twitter announcement here: For inspiration, check out some of the previously merged PRs in the repo: https://github.com/playcanvas/engine/pulls?q=is%3Apr+is%3Aclosed A particularly cool submission from the last month or two was area lights: https://github.com/playcanvas/engine/pull/2535 But the PR can be anything: Bug fix Documentation improvement/add
  3. What physics engines are available for Javascript and/or Typescript? I've searched myself but maybe there's one or two I missed. I also found a post in these forums but that's over two years old now; It's a little disappointing to see that some of them aren't actively developed and lacking a lot of features. I put together a test to compare the different engines I tried - I've attached the files if anyone wants to try it out. Here are the engines I've tried: PhysicsJs http://wellcaffeinated.net/PhysicsJS/ - Incomplete: lacking simple features like constraints - Seems li
  4. hello all Abit wired question but is there any tool that given HTML with included javascript can Flaten all the page to 1 big HTML and javascript file ? Thanks
  5. Hello everyone! Nice to make your acquaintance. It’s been awhile since I’ve been active on here, and I’d like to change that. So let’s start a conversation. Whatcha working on? You a team? Solo developer? Let’s chat! I’d love to hear from you.
  6. I am following the excellent book Foundation Game Design with HTML5 and Javascript. I have a piece of code, which works but i'm not sure why. function destroyAlien(alien) { //Change the alien's state and update the object alien.state = alien.EXPLODED; alien.update(); //Remove the alien after 1 second setTimeout(removeAlien, 1000); function removeAlien() { removeObject(alien, aliens); removeObject(alien, sprites); } As you can see it is a function which uses setTimout to call another function. It only calls removeAlien function when it is inside the main function. If
  7. I created a simple particle class to use in the space shooter I'm working on. It's a 105-line class available for elementary particle effects, though it can't do everything an advanced widget library does. You can download from gitlab or below and use it in all your hobby and commercial projects. Cheers. https://gitlab.com/bihenaso_games/shittypixiparticle/-/blob/master/static/libs/shitty-pixi-particle.js The test video is in the link below. shitty-pixi-particle.js
  8. I have this idea for creating a character customization system. The system would be implemented as follows. 1) Organize a base template sprite sheet with character components arranged in a composition for future compositing. Example: Lets assume a full body template for a characters design is 125 by 125 consisting of head, body, and leg components. The head component of the character would use 25 pixels and would be isolated on separate parts of the sprite sheet that occupies the respective pixels while the rest of the 100/125 pixels are blank. The same would be done for the
  9. Hi all and good day! 13 days ago started with new project and would like to share some stuff with you It's not completely from scratch, but took some base from my prev game DatTank [https://dattank.io]. How it looked 13 days ago How it looks today [melee attacking sys example] Would like to know if it would be interesting for somebody to read through some details in some articles or thms like this. Uh, and would be awesome to get some feedback Thx for your attention! ps: If you want to get quick updates from me follow on https://twitter.com/iOhmed
  10. Hello, Hi everyone, I'm developing a new hospital manager game; at the moment the main engine has been implemented and numerous other functions are being developed. For now, the developed language is Italian, but internationalization is planned. The game site is univerhosp.variousdom.it I need to find some beta testers to verify the functioning and the response times; I also created a forum with explanations. In the forum everyone can insert ideas, doubts and any information that may be useful for development. The forum is accessible from the game menu.
  11. Hi I have an image like the picture below. I need to resize this image.(between x2 and x10) When I resized with Canvas's own features, I couldn't get the image I wanted. The image was pixelated. I used OpenCV's javascript library for this. (To be able to do interpolation) But here I did not get the exact result I wanted and it was slow in speed(40 - 60 ms). The resizing speed should be between about 10 - 20 ms. Then I wanted to write an algorithm myself, but I could not prevent pixelation, and the image I wanted was not revealed. In fact, if I can make gradient for eac
  12. I am trying to develop a simple Canvas game, but I'm currently stuck at making the enemies display itself. Heres the code I'm using : <script type="text/javascript"> // SETUP INICIAL var canvas = document.getElementById('canvas'), ctx = canvas.getContext('2d'); var innerWidth = 360, innerHeight = 620; canvas.width = innerWidth; canvas.height = innerHeight; // VARIAVEIS var score = 0, lastTime = 0; // TECLAS DE MOVIMENTAÇÃO window.onkeydown = pressionaTecla; function pressionaTecla(tecla){ if(tecla.keyCode == 38) {
  13. Hello guys, I found one of my old projects on the computer and decide to remake it and share it with you. It's a simple 2D game, made in HTML5. Enjoy it. http://covid19arena.com/
  14. Hi, I wanted to make a game that's really challenging and simple at the same time. Something that will require some skills and not just a simple mindless game that shows a lot of ads. Something that you will need to get used to first, learn the rhythm of the game and then be able to complete the levels. So after 5 months (only working on the weekends; not all weekends), I have finally released a playable version of the game in the Google Play Store. Let me know what you think. I would really appreciate some feedback and what you think about the game. It's not much, but hey,
  15. I am trying to make a game so I tried to load a tileset, to help me make the game, but when I try to play my game, this shows on the console- ```Cannot read property 'addTilesetImage' of undefined``` This is my code: ``` Ball.Level1 = function (game) {}; Ball.Level1.prototype = { create: function () { var map; var layer; this.map.addTilesetImage('element-h'); this.map.addTilesetImage('element-w'); this.map = this.game.add.tilemap('map', 32,
  16. Hello, hope you'll are doing fine. I'm a beginner programmer and recently I've been working on a 2d physics game engine in JavaScript. Everything seemed to be working fine until I have come across an annoying bug in my push mechanic. I have created a 2d collision system where object A will be pushed away b object B, etc. In addition, I have created a push mechanic meaning, object A can push object b (if it’s not solid). However, I have come upon a problem where e.g. object A (Player), object B (box which the player can push) and object C (Solid wall), he problem occurs when object a pushe

  19. Hi everyone, I have a picture that I draw pixel by pixel on the canvas. Size of the image: 512 * 256. When I make this picture 1536 * 768, the image looks very bad. I think I can use interpolation to fix this. But I couldn't find a good javascript library. It didn't work in the libraries I found. Is there anyone who can help me with this?
  20. If you search for how to detect mobile devices by JavaScript you will find confusing information such as looking for the string "Mobi" in the browser identifier, and other unreliable stuff. In the past people checked screen size but that no longer works because some mobile devices have huge numbers of pixels. Even the usually reliable Mozilla Developer Network pages are contradictory on trying to detect touch screens. They have an article from 2011 which says to check whether the global window object has a property called ontouchstart (except that for Internet Explorer look at navigator.m
  21. I want to share a small PDF booklet with JavaScript coding challenges: https://codeguppy.com/site/download/50_coding_challenges.pdf These coding challenges are designed for beginners and intended to offer the foundation that they may need when developing mini-games on https://codeguppy.com or any other platform.
  22. Hello guys, I'm Hipreme(aka MrcSnm). I have some experience developping some games, and over the time I developed these games I found some need of having a tool that would generate enum for acessing my resources via intellisense. This tools is Licensed on LGPL 3 In every game I developed, at some time, I wrote some code for storing in variables the path for my resources or some easier access. By thinking in this problem, I created one tool that is meant to help every game developer in any language by dynamically updating these resource enumerators when you drag'n drop in your fo
  23. 3D perspective is perfectly possible in the plain 2D canvas of HTML5/JavaScript without the overhead of any frameworks or libraries. As an example I have recently created a small game in response to a GameDev challenge relating to DOOM. I was troubled by a bug in my display when the player moved close to walls. I sat down and made some diagrams to help me get my thinking straight and then I was able to solve the bug. I thought others might find my diagrams useful so I am adding them here. My aim is to demonstrate that 3D perspective is perfectly possible in the plain 2

This is how I am adding into my code : this.animation = bodymovin.loadAnimation({ container: document.getElementById("game"), // Required path: "assets/json/RainLoop.json", // Required renderer: "canvas", // Required loop: true, // Optional autoplay: true, // Optional name: "Hello World", // Name for future reference. Optional. }); But here problem is, this animation is attaching to the HTML DOM elements and so that
