  1. Hi, I'm a designer and I'd like to reach out to others for input or even collaboration. Lots of my javascript work is on github in the spirit of sharing and learning together. Like an open source sketchbook. I like making small experiments that might be included in something bigger. I often play with mechanics, audio and visual elements to look for interesting things : http://type76.com As you can see, it's lots of generated, three.js and canvas stuff, with a game dev leaning. I'm keen to go in new directions too. It's hard to find interest among my social circles, so I'm reaching out here to see if people are into this kind of thing. It's not business. It's about hitting ideas off each other, collaboration, fun and learning together. Maybe we can make an itch.io page if there is the will. You're welcome to join the discord server : https://discord.gg/KUqcuWu I'd love to see your experiments. Here or on discord. Things that aren't full games, but are fun and interesting concepts. This seems the place to look for like minded folks. Have you got a sketchbook? Is there a good CMS for this? I might be doing it wrong. Are there any other communities for this apart from discord servers full of revshare projects?
  2. Hi Everyone, I want to create same thing like this in phaser 3 using graphics library or by any other way. I cannot find compatible code for replacement in graphics library. Any help will be highly apprecited https://codepen.io/kangax/pen/dajwE Many Thanks
  3. Hi all, I am doing a test to a client who ask me to build a dynamic using a sequence of 3D rendered images, I told him than that is not the right way in WebGl, the correct is to convert the 3D objects and use than. But he said than right now they can not do that. So I tryed to use Dynamic Texture with canvas method and it works, but I wanna know if somebody knows a way to preload the sequence of images in BJS, to get better? Because I think that has a delay right now about the loading issue. You can see it here http://iprojects.space/upwork/laval/ Thanks
  4. Hi everyone. For the last few months I’ve been working on a simple HTML5 2D side scrolling action game called Theraxius. It's nothing new and revolutionary, it's more like an evolution of different technology. The game also includes a level editor so you can create your own levels. Engine (all game logic and level editor) is written completely in JavaScript, no download is required. Just load and play. Level data (stored in JSON format in the database) is exchanged thru Ajax calls. Server side is written in PHP. All images and sounds are preloaded from the server before play. The game uses HTML5 features like canvas, Fullscreen API, Pointer Lock API, Audio,… At this moment only Chrome and Firefox are supported. The game is meant to be played on PC, phones and tablets are not supported. In the next weeks I’ll try to post some videos, try to add registration (for newsletter and later for public test). Release date: when it's done Official page: theraxius.com Screenshots (for bigger images, please visit official page):
  5. 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.
  6. Hello everyone! I'm trying to accomplish the following task: - When there is a change of state I want to take a screenshot of the canvas, show to the user while the state is changing. Now I read that I should use canvas.toDataURL to obtain the base64 encoded Image. I can't understand the steps to accomplish this task. 1) I save the URL with canvas.toDataURL(). 2) I should convert the base64 to an image right? 3) I should add the Image to the cache OR i Should do a load.image? 4) The operation should be async right? Because in my trying the debugger console is saying that the image hasn't been retrieved and I don't understand how I can make toDataURL (or the conversion from base64 to png) async because there are no methods. Thanks for the help!
  7. Hello, I'm seeing this behaviour that I can't understand, when applying a tint color to a sprite while using canvas as renderer. Right now for CORS reasons we're forced to use canvas in our app. I say this because in webgl the issue doesn't happen. The thing is the we're cutting images into stripes and applying a tint to each stripe, but this creates a line between the stripes: https://codepen.io/rhernando/pen/8fb06d28861d63ca5a6868f88c71f150?editors=0010 Just click the button to apply/remove the tint and you'll see the issue. Why this happens?, is there a way around this or is just what we get in canvas? Best, Rodrigo.
  8. How to make click Pixelperfect on Canvas DEMO + Tutorial https://leoche.github.io/Pixelperfect-Click-Canvas/ Summary There is no easy way to draw something and capture a pixel perfect click on it with HTML5 canvas. But there is a trick! We can attribute a random color to each Sprite we create then on a new blank buffer canvas, draw all sprites but only with their respective colors. Capture mouse input coordonates on real canvas then look the color of the pixel on the buffer canvas then compare this color with your sprites. If colors matches you clicked on this sprite! Tada! Real pixel perfect inputs! Initial Setup I took 3 sprites. So Basically here, we have a Main class which have an Array of Sprite(x, y, img) instances: this.sprites = [ new Sprite(100, 100, this.imgs.bed), new Sprite(52, 146, this.imgs.table), new Sprite(80, 135, this.imgs.z) ] I had to set coordonates to make those sprites overlaping each other The class for Sprites is pretty simple: export default class Sprite { constructor(x, y, img) { this.x = x this.y = y this.img = img } render (ctx) { ctx.drawImage(this.img, this.x, this.y) } } For this example i didn't add a z or depth property to Sprites, we admit in this example that Sprites ordering is made by their position in array. I set up a time loop to call render which call render on each Sprite: setInterval(() => this.render(), 1000 / 30) ... render () { ... this.sprites.forEach( sprite => { sprite.render(this.ctx) }) } Result: Real things coming up First we need to generate a random color for each sprites and make a new method to render the image but with only one Color. constructor(x, y, img) { this.x = x this.y = y this.img = img this.name = this.img.id.replace('img-', '') // Return 'bed', 'table' or 'z' this.id = Math.floor(Math.random()*16777215).toString(16); // Return a random HEX Color console.log("Created '" + this.name + "' with color #" + this.id); //We want here to see what color is generated for this sprite } Console returns Now we want to create a method renderColor with a canvas buffer, So we just need to create a canvas with img sizes, fill with generated color then drawImage with destination-atop composition. renderColor (ctx) { var buffer = document.createElement('canvas'); buffer.width = this.img.width; buffer.height = this.img.height; var bx = buffer.getContext('2d'); bx.fillStyle = '#' + this.id bx.fillRect(0,0,buffer.width,buffer.height); bx.globalCompositeOperation = "destination-atop"; bx.drawImage(this.img,0,0); ctx.drawImage(buffer, this.x, this.y) } For debug purposes we can now see the result if we update the render to render those colors sprites: render () { this.sprites.forEach( sprite => { sprite.render(this.ctx) sprite.renderColor(this.ctx) //DEBUG }) } Which give us this result: Create a global buffer for all this color sprites in Main constructor and render color sprites to it instead of the real canvas this.inputCanvas = document.createElement('canvas') this.inputCanvas.width = this.canvas.width this.inputCanvas.height = this.canvas.width this.inputCanvasCtx = this.inputCanvas.getContext('2d') ... render () { this.sprites.forEach( sprite => { sprite.render(this.ctx) // Previously: sprite.renderColor(this.ctx) sprite.renderColor(this.inputCanvasCtx) }) } then add an event listener to the real canvas and get pixel informations on the buffer canvas this.canvas.addEventListener('click', event => { let color = this.inputCanvasCtx.getImageData(event.layerX, event.layerY, 1, 1).data }) Convert the color data to HEX, and just compare with existing sprites! this.canvas.addEventListener('click', event => { let color = this.inputCanvasCtx.getImageData(event.layerX, event.layerY, 1, 1).data let hexColor = ("000000" + this.rgbToHex(color[0], color[1], color[2])).slice(-6) console.log('You just clicked on color #' + hexColor) let sprite = this.sprites.filter(sprite => sprite.id === hexColor) // You now have the sprite yea! }) ... // RGB Util rgbToHex(r, g, b) { if (r > 255 || g > 255 || b > 255) throw "Invalid color component" return ((r << 16) | (g << 8) | b).toString(16) } Console returns You now have your clicked Sprite!

  9. Which is the best way to paint the canvas with an input Fragment shader using BABYLON? Not a mesh but directly the canvas itself. I could set up an ortographic camera and a plane in front of it, but that's... just bad. Thanks in advance
  10. Hi guys, I'm new to this and I have an issue in my current working project(it's first in phaser). I want to know how can I zoom in the game when it's opened in a mobile browser? The game is too small and I want to zoom and slide the whole canvas in the browser window. I can do this from outside the canvas but I cannot drag then from the canvas itself. Please help! Thank you.

  14. Hello, found this solution for creating video. but this result video is faster than runtime animation. thought that _alpha variable usage is strange, so tried milliseconds controls but not easy for me. in my opinion every 1000/fps milliseconds, to render and to capture are correct. but it makes more speedy video any advice? ps. i solved using CCapture. but video quality is not good. function record() { scene.getEngine().stopRenderLoop(); render() } function render() { requestAnimationFrame(function() { scene.render(); capturer.capture(scene.getEngine().getRenderingCanvas()); render(); }); }

    Framework or Canvas

    Hi, I'm new in the HTML5 game developing, and i want to know what framework or engine to use for my first 2d game. I want a framework that permit to get high-performance,or i should to use canvas? Maybe,could you link to me some tutorials about thet framework? Thank. Sorry for my english,I don't know well english
  16. I'm sorry for making the title that long....and also my content will be... Recently I'm quite tortured by a tricky problem, mainly on iOS mobile, things are like this... I inserted a Babylonjs project into a third-party homepage through iframe tags. As you know, the home page has header, footer, another content and the iframe part. When I scroll to the iframe part, and want to interact with the canvas, as long as I tap the canvas, the page jumps to the bottom immediately. Strange! I scroll back, and continue to pinch, rotate the canvas, it goes normally (do not touch other part, only the canvas after jumping). As long as I have tapped the UI, and then tap the canvas, history will happen again. I tried other projects (also build with Babylonjs), some will not have this problem. So I made a detailed comparison, excluding the potential problem raised by html ,css. The main difference might be the version of Babylon.js. The ones that have jumping problems use the babylon.3.1.1.min VERSION , while those don't have problem, use this Version , it's compressed and I forgot the version now. Can anybody tell which version the latter is? and what's difference between them, especially about issues like canvas focus, tapping event on iOS... The test link that having the problem is this , the visit speed might be slow out of China. But the problem will be like what I mentioned above. I guess it's something about canvas.focus(). but not sure..I know you guys are more experienced and smarter. I would really appreciate!!!!!!!! 5e2233d9ce8a56b9700997ac243d5838 (1).mp4
  17. Good day folks! Im completely brand new to Babylon (3D site building in general) and have become an instant fan! Im having a few issues and would like to see if folks can help: 1. I want to have 4 boxes on my site and align 2 on the right and 2 on the left (Such as the "Fashion Show" demo on the main page), how to go about doing this? 2. I want to make my logo and place it between the boxes, any recommendations on how to make this happen? 3. Also I want to place images on the boxes and link them to another site when a person clicks them, how do an ahref in this type enviorment? 4. I would like to change the canvas to black, how to do this? Thank you for all your help💋 Meka
  18. 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?
  19. I've gotten most of my game done, but I still have to make at least something that the player can do other that walk around the map and bump into things. I decided to add coins to collect, but I just have one problem: I've never added collectibles to a game before. Please help. I need to get this done in before next Friday. EDIT: I tried coding, but a coin wouldn't spawn anywhere other than the upper left corner. I tried setting its draw setting to this.randomRange, so it would spawn randomly on the map. Here's the code: //establish variables var canvasBg = document.getElementById("canvasBg"), ctxBg = canvasBg.getContext("2d"), canvasEntities = document.getElementById("canvasEntities"), ctxEntities = canvasEntities.getContext("2d"), canvasWidth = canvasBg.width, canvasHeight = canvasBg.height, player1 = new Player(), isPlaying = false, cash = new collectibles(), obstacles = [], //animation requestAnimFrame = window.requestAnimationFrame || window.webkitRequestAnimationFrame || window.mozRequestAnimationFrame || window.oRequestAnimationFrame || window.msRequestAnimationFrame || function (callback) { window.setTimeout(callback, 1000 / 60); }, imgSprite = new Image(); imgPlayer = new Image(); imgMoney = new Image(); imgSprite.src = "img/testroomImage.png"; imgSprite.addEventListener("load", init, false); imgPlayer.src = "img/temp.png"; imgPlayer.addEventListener("load", init, false);

} What's wrong with it? just editing it in the slightest made the coin disappear when I refreshed the page.
  20. So, I've managed to make my character sprite move, but the collision doesn't work and the sprite can move out of bound even though I've defined the outOfBounds function. Is there anything I can do about this? And so you know, when this: if (!obstacleCollision) { this.drawX = newDrawX; this.drawY = newDrawY; } is changed to this: if (!obstacleCollision && !outOfBounds (this, newDrawX, newDrawY) { this.drawX = newDrawX; this.drawY = newDrawY; } The sprite is locked in place! I had to remove that part in order for the code to work.
  21. Hello guys, I'm new to this forum and to BabylonJS. The question about multiple scenes isn't new, I know. I already read some threads, but the answers didn't work for me. I need two scenes that act simultaneously. Only one scene should be visible at a time, the other should run in the background. I also want a button in each scene to switch to the other scene. For some reason I can't run my scenes with playground, so i just send you my html-files as an example. I'm sorry for the effort. 2engines.html is a modification of a version someone posted in one of the threads about two canvas and engines. It's nearly what I want, but the button to switch the scene is shown for just one scene (you can switch the scene without button by pressing '1'). I don't know if I have to use multiple canvas for my request. Multiview.html is an example how it could look like (also an experiment with multiviews). I call the createScene-function everytime to switch, so the scene will always start from the beginning. I want to switch to the other scene without restarting it, so you can see the progress of whatever happens there, while running in background. The main goal is to create a platform with a couple of minigames (solve a puzzle, realtime strategy, first-person-shooter etc.) via browser. Students can program their own agents and let them fight against pre-programmed agents. People or students that don't play should be able to watch one of those games and switch the camera (or scene) to watch another game. I'm trying to find out if it's possible to realize this concept (or rather the representation with scenes and cameras) with BabylonJS. I'm not the one creating this platform. It is part of my study project to find out, if BabylonJS is the right framework for this. Wow, that was a huge spam. I hope there wasn't too much unnecessary information and that I've made myself clear. Best regards. 2engines.html multiview.html
  22. Hello, here I created game but I have a problem with a function. When did the party begin to have a message that says "Go!" and I would like it to change when the player reaches 100 points. My last try script that absolutely does not work. function textChange() { updateScore(); if (player.score == 100) { updateText("Good!"); } } Thanks all
  23. Hello everyone! i have a very specific question, i need to somehow pause the game at the end of the frame render, execute a function and then render the next frame, and do the same over and over, is that possible? if there is no function that would allow to do that, what is the function that takes care of the scene rendering so i could modify it? Thanks!
  24. Hi All, I have been working on a Simple paint app for kids. I have a problem in implementing the simple brush tool. Im getting small dots and line here there in the screen Unable to draw on free hand movement like a brush. kindly help. playGame.prototype = { preload: function () { }, create: function () { game.stage.backgroundColor = '#222222'; game.input.onDown.add(this.onStageDOwn, this); game.input.onUp.add(this.onStageUP, this); }, onStageUP: function () { game.input.deleteMoveCallback(this.paints, this); }, onStageDOwn: function (pointer, x, y) { graphicsMC = this.game.add.graphics(); graphicsMC.lineStyle(2, 0xffd900, 1); graphicsMC.moveTo(pointer.x, pointer.y); game.input.addMoveCallback(this.paints, this); }, paints: function (pointer, x, y) { graphicsMC.lineTo(pointer.x, pointer.y); } };
  25. We are seeing very unusual performance on a vizio smart tv platform. Pixi finds WebGL and so does HTML5Test. However, a simple test based on bunnymark shows 14fps + video blanking between each frame. When we switch to the Canvas2D renderer, we see 30fps and smooth animation, no blanking. Has anyone played with the vizio? They do have a custom SOC (2 core, 4 gpu) which leads me to suspect there is some quirkyness in their webgl implementation. We also ran a standard bunnymark with similar bad webgl results.
