    cave2d.com/game5 is done

    I got to a good stopping point on cave2d.com "game5" so I think I'm done with it! *POST*. Game5 is the sequel to game2 that nobody asked for. It has local multiplayer support, keyboard/mouse and touch support, a few different weapons, tractor beams, shields, explosive mines which are fun to chain together, and sounds generated live with web audio. It was fun to make (which is good because I don't plan to make money with it) and I'd love to hear any feedback on it - thanks!

    Changing image resolution for mipmapping

    Hi there, I'm working on an app showing user uploaded maps (bitmaps). These maps can be of any resolution and often they are very large. Now down-scaling these images they become ugly and crunched, so I need to use mipmapping (Working in WebGL). I know mipmapping only works with "powered by two" resolutions, but is there any way I can resample my odd-sized maps, to fit into a "pb2" resolutioned baseTexture, and still know the original specs. Or how would you work around it? Thanks
  4. Hi, does anybody know a professional/real mobile game made with Three.js/Babylon.js/Playcanvas? It seems like no one is betting for these technologies and goes for Unity or similar.

  8. We have atlas exported with Texture Packer. Run-time every texture is cropped by 1 pixel. This pixel is added to the opposite of the texture. Likewise https://github.com/pixijs/pixi.js/issues/5087.
  9. Today I got a headache from how... why... phaser3 handles the camera.setZoom(); - First thing I learned: all bodies need to be recalculated after .setZoom. - in WebGL works as expected. - in Canvas, Tilemaps are huge, the zoom isn't on point and even by recalculating the bodies, collision is way off. This could be reproduced by using this code and setting WebGL / Canvas. The code behaves differently depending on which you choose, and neither of both has a valid result. Am I missing something? Game config: // Game config type: Phaser.WEBGL, width: WIDTH, height: HEIGHT, scene: Level, resolution: 1, pixelArt: true, antialias: false, hidePhaser: true, roundPixels: true, backgroundColor: '161C22', zoom: 1, physics: { default: 'arcade', arcade: { gravity: { x: 0, y: 250 }, debug: true } }, tilemaps and camera: // Tilemap method setMap() { // # Add Tilemap this.config.map = this.make.tilemap({ key: 'map', tileWidth: 8, tileHeight: 8 }) const tileset = this.config.map.addTilesetImage('tilemap'); // # Add Tilemap Layers this.config.layers.background = this.config.map.createDynamicLayer(0, tileset); this.config.layers.midground = this.config.map.createDynamicLayer(1, tileset) this.config.layers.ground = this.config.map.createDynamicLayer(2, tileset); this.config.layers.forground = this.config.map.createDynamicLayer(3, tileset); this.config.layers.water = this.config.map.createDynamicLayer(4, tileset); // # Configure Tilemap Layers // replace with array of actual bodies this.config.layers.ground.setCollisionBetween([]); this.config.map.objects[0].objects.forEach((obj)=>{this.setMapObject(obj)}); // # Configure z indexes this.config.layers.background.setDepth(0); this.config.layers.midground.setDepth(1); this.config.layers.ground.setDepth(2); this.config.layers.objects.setDepth(3); this.config.layers.enemies.setDepth(4); this.config.layers.player.setDepth(5); this.config.layers.effects.setDepth(6); this.config.layers.water.setDepth(7); this.config.layers.forground.setDepth(8); this.config.layers.overlays.setDepth(9); this.config.layers.ui.setDepth(10); this.setTransition(); } // # Configure main camera const m = this.config.map; this.physics.world.setBounds(0, 0, m.widthInPixels, m.heightInPixels, true, true, true, true); this.cameras.main.setBounds(0, 0, m.widthInPixels, m.heightInPixels); this.cameras.main.setZoom(8); this.cameras.main.setRoundPixels(true); this.cameras.main.useBounds = false; this.config.layers.ground.setCollisionBetween(0, 8000); // add sprites this.config.player = new Player({ scene: this, x: 20, y: 30}); this.cameras.main.startFollow(this.config.player); this.physics.add.collider(this.config.player, this.config.layers.ground); Any thoughts, on this, would be helpful.
  10. Hi all, We have a web based 3d project to be made with babylon. all models and baked diffuse textures will be provided, FBX and jpg textures, what you need to do is : 1-import assets, create PBR surface shader for building and a reflective transparent glass shader for windows 2- a directional light with shadow 3-implement a navigation system with left click hold to rotate around model, middle click pan , and right click hold to to zoom in and out 4- ability to double click and move camera to teleport on any point on the model to explore up close. 5- UI system with dimension and text where you double click on the UI you zoom on it. 6- Button to toggle UI on and off 7- full screen button This whole system is already implemented with unity and its live on following link you can see what exactly we need to make. What we need is this to be made with native WebGl using Babylon js or 3 js so all browsers on mobile,Mac and PC could open it, this is critical for this project. we want the exact look and feel. http://www.v2igroup.com/edq/ I reckon we can do this hourly based AUD, payment will be via paypal. we will be having 7 of this all the same only buildings type change, so first one would require more work the rest would be just replacing and adjusting the buildings and context. please let me know if you have enough experience to take on this task. EMAIL sam.g@v2i.com.au yours, Sam

    WebGL: cloud-based or self-hosted?

    WebGL is all about online. It seems quite natural that some tools for creating 3D Web content are offered as web services. But is it safe to rely on them? https://www.soft8soft.com/webgl-cloud-based-or-self-hosted/

    Verge3D 2.5 for 3ds Max

    We are finally releasing Verge3D 2.5 for 3ds Max – it took longer than we thought, yet the amount of new features that we delivered this time was definitely worth waiting for. In this release are reworked physical materials, support for bipeds and character rigs, animation of material parameters, support for more texture settings, anisotropic filtering and various new puzzles to help creating even more engaging interactive scenarios without coding.

    Fastest way to do masking?

    Pixi usually performs really well even with heavy scenes. I can put hundreds of objects, even thousands of particle sprites and get 60 FPS on mobile. I typically only use a single masked object in a scene but recently needed to use more and I was surprised at how badly Pixi performed with masked objects. For every masked sprite, I lost about 5 FPS on mobile (both Android and iOS on old and new phones, newer phones actually performed worse in some cases). By the time I added 4 masked sprites, I was down to 40 FPS, adding 10-20 masked sprites dropped to 20 FPS with really bad stuttering. As soon as I switch the mask off by removing the assignment, it goes from 20 FPS to 60 FPS, even with 200 of the same sprites. It doesn't seem like it should take so much resources to do masking given all the other effects that are possible. Tinting for example, adds a value to every pixel and costs nothing. Masking is just checking a pixel in one object and setting the equivalent pixel in the other object. Is there a faster alternative to using object.mask = mask? Is there a graphics buffer I can use to set the pixel values myself, e.g if I could create an array of pixel values and generate a texture buffer from that. Javascript is pretty fast with arrays. The main thing that bothers me is that the low performance happens with static masks. I could understand the performance hit when the sprite is animating relative to the mask but not when they are both static. Why doesn't it buffer the masked sprite and use that over and over like a normal sprite? I found a thread that describes the same issue, unfortunately I'm stuck on v3 for now: https://github.com/pixijs/pixi.js/issues/2163 I just found the following with a possible alternative using multiply blending: https://github.com/pixijs/pixi.js/issues/3735 To isolate it, it suggests using a voidfilter. Is this the fastest way to do masking in Pixi? If so, is there example code for this? Say that I did at some point want to draw a texture pixel by pixel, one way would be to draw a tinted 1x1 pixel sprite into a render texture. Is there a better way than this e.g set values in a buffer and convert it to a texture? Is there a way to read a pixel color/alpha value from a sprite or texture. There seems to be an extract function for WebGL and Canvas but it looks like this extracts the viewport. It would be good to be able to render sprites to a rendertexture and be able to read the pixel values of that texture using pixel co-ordinates.

    VERGE3D 2.5 FOR BLENDER RELEASED

    We are glad to present a new release of Verge3D – the Blender version comes first this time. We included several significant improvements in this release, such as basic support for Cycles nodes, puzzles for dragging objects with the mouse or gestures and puzzles for limiting object movement, support for anisotropic filtering for textures, Unicode characters and new settings for constraints. We have also created a new application to demo all these features. In this release: • Support for Cycles renders, including physically-based lighting model and the Principled BSDF node! • New Puzzles for positioning, rotating and zooming objects by using the mouse or touch screen. This tool has unlimited possibilities whether it's controlling the a complex equipment or the simple arrangement of the furniture in your apartment. • Support for international and special characters for the names of objects, animations, files and projects. • Textures now look much better due to anisotropic filtering feature. • Ability to control constraints, procedural animations, sounds and many other features in the Puzzles editor. • Various UI/UX improvements in App Manager. Remember the NASA Curiosity application? Now you can create the same app without a line of code using only visual logic blocks, look at our new example.

  19. Some time ago I started my own twitch channel where I have been working at 2D space massive multiplayer game development. I try to utilise my roadmap task by task, telling about what I'm doing. I have using javascript, node.js and top-notch technologies such as service workers, websockets, server-side rendering, webgl and famous libraries & frameworks like React, Webpack, Koa. And finally the question, does anybody interested in watching Twitch to improve their skills in gamedev and programming based on real game projects? I'm free to welcome other developers, answer for any technical questions. For me it's basically chance to meet new developers, increase of motivation, extra opportunity to find anyone who can help me in gamedev as well. Thank you!

    NASA turns to Verge3D

    As Verge3D is getting more and more popular among interactive designers and web developers, quality applications are starting to appear online with regularity. We could not resist to share with you an amazing example of using our toolkit by NASA’s Jet Propulsion Laboratory. Experience Curiosity, the award-winning 3D web app that tells the story of the tireless Mars rover, is now powered by Verge3D! Created by NASA to celebrate the third anniversary of the Curiosity rover landing on Mars, this app was featured by the Khronos consortium on SIGGRAPH 2015 as a breakthrough application powered by then-young WebGL technology.

    Farmer's Journey

    This is a simple runner (walker exactly:) ) made with Verge3D engine and runs directly in the browser. All was modelled in Blender, even texturing in 90% made in Blender: I just set up shaders and light and baked it to texture. In my pipeline I've also used 3ds Max, Krita, Webflow, Gimp and Audacity. The game was made without coding in two weeks by only one artist. Character and most of the assets based on concepts of Vihn Nguyen . Thanks to Forget the Whale for the soundtrack. Link to the game: DIRECT LINK You can also download all source files with mesh, textures and sounds HERE Some art related to the game can be found here on my ARTSTATION PAGE
  23. Hi guys, We developed a game last year with phaser 2.3.0 and webgl, it worked fine on computer browsers and mobile devices. But since the last update of chrome for android (v53.0.2785.97), the screen is flickering until it becomes totally black, without any error or warning. The issue is present on mobile only, it worked on chrome for android v52, but not v53. We tried to upgrade to phaser 2.6.2, same issue on chrome for android v53. If we use Phaser.CANVAS instead of webgl, it works fine, but we prefer using webgl for performances. Does anyone encounter the same problem? Thanks for your help. Joe K.
  24. Hi, I made a web-app for planning and visualizing time segments. It looks like this in action: napchart gif2.mp4 I do all the calculations in pure Javascript, and had to write a lot of code to code all the shapes make hit detection work for all shapes. I am drawing all elements in HTML5 canvas. I am looking into refactoring the codebase and adding more features. In that case I am wondering if a library rendering to WebGL would help me? Things I want: Easy way to prevent text overlapping Easy way to add small animations and slick effects Smooth animations with more complex and advanced shapes than in the video. The bottleneck is when animating the shape, and then the JS have to calculate all elements every frame, but would WebGL help with that? This is a non-trivial usecase, and I think it may be best to just use pure JS and canvas, but to be honest, I don't really know how WebGL works, and in what way it helps. Any WebGL heads here?
  25. I downloaded 16 lessons to learn WebGL programming of this WebGL tutorial from GitHub, the first four lessons are fine and in the canvas HTML5 element I see what I should see, but in lessons 5 to 13, the canvas is entirely black and I don't see any colorful shape on it. In lesson 14, I only see in the center of the canvas the white text "Loading world...", the canvas in lesson 15 is again entirely black and in the last lesson number 16, I do see in the canvas a moving and turning white shaded box from left to right during few seconds and then it disappears and after that the canvas is entirely black again. According to his/her WebGL tutorial, the canvas in each lesson should show me nice colorful shaded and textured 3D shapes transforming in real time on the canvas, not everything black, but this is not happening for me. Why? I am using the latest version of Google Chrome internet browser. What can possibly cause this? In addition to the 16 lessons, there are also 3 examples, the first two examples are fine, i.e. in the canvas I see what I should see, but in the third example the canvas is entirely black again and I guess that this should not be happening.
