    Playground: https://plnkr.co/edit/BGNYcIJRiJXpd9N4?preview GitHub: https://github.com/8Observer8/how-to-set-up-box2dwasm-with-importmap-rollup-js glMatrix is just a bonus: index.html <!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>How to set up Box2D-WASM with importmap and Rollup for JavaScript</title> </head> <body> <!-- Since import maps are not yet supported by all browsers, it is necessary to add the polyfill es-module-shims.js Source: https://threejs.org/docs/index.html#manual/en/introduction/Installation --> <script async src="https://unpkg.com/[email protected]/dist/es-module-shims.js"></script> <script type="importmap"> { "imports": { "box2d-wasm": "https://unpkg.com/[email protected]/dist/es/Box2D.js", "gl-matrix": "https://cdn.jsdelivr.net/npm/[email protected]/+esm" } } </script> <script type="module" src="./js/index.js"></script> </body> </html> init-box2d.js import Box2DLib from "box2d-wasm"; export let box2d = null; export function initBox2D() { return new Promise(resolve => { Box2DLib().then((re) => { box2d = re; resolve(); }); }); } index.js import { box2d, initBox2D } from "./init-box2d.js"; import { mat4, glMatrix } from "gl-matrix"; async function init() { await initBox2D(); const { b2Vec2 } = box2d; const vec = new b2Vec2(1, 2); console.log(`vec = (x: ${vec.x}, y: ${vec.y})`); const mat = mat4.create(); console.log(mat); console.log(glMatrix.toRadian(45)); } init(); Instructions for building and running the project in debug and release: - Download and unzip this example: https://github.com/8Observer8/how-to-set-up-box2dwasm-with-importmap-rollup-js - Go to the example folder in the console: `cd how-to-set-up-box2dwasm-with-importmap-rollup-js` - Install these packages globally with the command: > npm i -g http-server rollup uglify-js - Add the Rollup bin folder to the Path. Type this command to know where npm was installed `npm config get prefix`. This command will show you the npm location. You will find the "node_modules" folder there. Go to the "rollup/bin" folder and copy this path, for example for me: `C:\Users\8Observer8\AppData\Roaming\npm\node_modules\rollup\dist\bin`. Add this folder to the path variable. - Run http-server in the project directory: > http-server -c-1 Note. The `-c-1` key allows you to disable caching. - Start development mode with the following command: > npm run dev Note. Rollup will automatically keep track of saving changes to files and build a new index.js file ready for debugging. You can debug your project step by step in the browser by setting breakpoints. - Go to the browser and type the address: localhost:8080/index.html - Create a compressed file ready for publishing. Stop development mode, for example, with this command Ctrl + C in CMD, if it was launched before and enter the command: > npm run release Note. After this command, Rollup will create a compressed index.js file. Compression is done using the uglify-js package.

    Hi, my goal is to have a canvas that spans 80% of the users browser and keeps aspect ratio of 16:9. I was trying different approaches throughout today, failing to reach the goal, but here's the idea I came up with that works on paper and in my head, but not in practice. Can anyone see where's the problem in my line of thinking? Conceptually: I pretend I have 1280x720 available and use it to position whatever I want on the canvas, using the 1280x720 coordinates system. Then I find out what screen size I have available and compute following values using following formulas: newWidth = window.innerWidth * 0.8 newHeight = newWidth * (16/9) scaleFactor = newWidth / lastWidth (when this is first called, lastWidth is 1280) In the test environment, I have larger screen than this, so I start with scaleFactor=1.2 and I have two sprite circles, for which I update both coords by sprite.x = sprite.x*scaleFactor equation. For moving the sprites at corresponding scale, this seem to work correctly. Similarly, I thought that doing sprite.set.scale(scaleFactor) or sprite.set.scale(scaleFactor, scaleFactor), will do the job correctly and performed following test: 1. Have it loaded for the first time in big window, with values being properly scaled (success?) 2. Have it loaded in a smaller window by clicking "Restore down" on window control, which scales things down by three times, scale factor 0.3, everything seems legit. 3. Have it loaded back in the big window as in (1), scale factor = 3 (scaling 300% up, as it scaled to 30% before), which works for coordinates, but scale is off (its way bigger, I will attach screens to demonstrate this). Why is 3 happening? // Hopefully minimum viable example of what is going on in my code, with unnecessary/irrelevant parts removed const targetAspectRatio = 16 / 9; const canvasWidthPercentage = 80; const baseWidth = 1280; const baseHeight = 720; let scaleFactor = 1.; const initialWidth = window.innerWidth * (canvasWidthPercentage / 100); const initialHeight = initialWidth / targetAspectRatio; // Keeping track of previous dimensions let lastWidth = baseWidth; let lastHeight = baseHeight; const app = new PIXI.Application({ width: baseWidth, height: baseHeight, resolution: window.devicePixelRatio || 1, }); document.body.appendChild(app.view); /* Here I spawn circles -> redacted from this sample, but attached below */ function resizeHandler() { const newWidth = window.innerWidth * (canvasWidthPercentage / 100); const newHeight = newWidth / targetAspectRatio; scaleFactor = newWidth / lastWidth; // scaleWidth == scaleHeight, due to aspect ratio lock I believe console.table({/* Debug you see in attachments */}) // Update the renderer size app.renderer.resize(newWidth, newHeight); displayedSprites.forEach((sprite) => { sprite.scale.set(scaleFactor) sprite.x = sprite.x * scaleFactor; sprite.y = sprite.y * scaleFactor; console.log("On window resize moved sprite to [x,y]=["+sprite.x+","+sprite.y+"]") }); lastWidth = newWidth; lastHeight = newHeight; } window.addEventListener('resize', resizeHandler); resizeHandler(); Wasn't sure it is relevant, but here's how I spawn those circles: const spawnCircle = (x, y) => { let graphics = new PIXI.Graphics(); graphics.beginFill(0xFF0000); graphics.drawCircle(50, 50, 50); // center coords (x,y) and radius graphics.endFill(); const texture = app.renderer.generateTexture(graphics); const sprite = new PIXI.Sprite(texture); sprite.x = x * scaleFactor; sprite.y = y * scaleFactor; console.log("Spawning a circle at [x,y]=["+sprite.x+","+sprite.y+"]") app.stage.addChild(sprite); displayedSprites.push(sprite); } spawnCircle(150, 100); spawnCircle(150, 300);

    Kaboom.js is a recent library for making games. Recently the version 3000 was released (They jumped from version 2000 to 3000, there aren't 3000 versions haha). Anyway, I really like the library. You make games with it by creating game objects by passing a list of components offered by Kaboom.js. Optionally you can create your own components as well. Here is my tutorial which lasts 7 hours where I go in depth on how to make a platformer game with it : Enjoy!

    MATRIX-ENGINE STATUS - [Integrated PWA addToHomePage/cache/] ✔ - [Integrated raycast (hit trigger detect), bvh animation] ✔ - [Basic Physics implementation based on cannon.js] ✔ - [FirstPersonController/SceneController Drag and navigation scene] ✔ - [Basic's Shadows vs lights (GLSL)] ✔ Description ℹ This is small but inspiring project. The benefits of this project is offering an overview of the entire application logic, easy native implementations (hybrid app), object structural. Thanks to Mr.Keestu i use (gl-program-structure) new version of glmatrix (2.0). Push&Pop matrix just like in opengles 1.1. Also can be downgraded to openGLES 1.1. webGL Lightweight library based on glmatrix engine. For multiplayer used webRTC done with io socket. Physics done with last version of cannon.js. I use free software Blender 2.90.1 for 3d Object mesh works. MatrixEngine is Blender frendly orientend lib. Also mixamo.com is great service used for creating my assets. Limitation ⚠ Basic implementation for physics (Cube, Sphere) Raycast not work after walk behind the object in first person mode Only static object cast spot light in right way for now. Need general more improvement on GLSL part. Next Features 🔜 General improvements in Lights section.

Take a look at : load_obj_sequence.js For now engine use objLoader to load all morphs. matrixEngine.objLoader.downloadMeshes( matrixEngine.objLoader.makeObjSeqArg( { id: objName, path: "res/bvh-skeletal-base/swat-guy/anims/swat-multi", from: 1, to: 61 }), onLoadObj ); In onLoadObj callback function: var animArg = { id: objName, meshList: meshes, // sumOfAniFrames: 61, No need if `animations` exist! currentAni: 0, // speed: 3, No need if `animations` exist! // upgrade - optimal animations: { active: 'walk', walk: { from: 0, to: 35, speed: 3 }, walkPistol: { from: 36, to: 60, speed: 3 } } }; FirstPersonShooter examples [WIP] Just like in eu4 shooter we dont need whole character mesh for FPSHooter view. I cut off no hands vertices in blender to make optimised flow. Feature [1.8.12] App.events Access. Take a look at the apps\fps_player_controller.js example. App.events.CALCULATE_TOUCH_DOWN_OR_MOUSE_DOWN = (ev, mouse) => { // From [1.8.12] // checkingProcedure gets secound optimal argument // for custom ray origin target. // mouse console.log(mouse.BUTTON) if(mouse.BUTTON_PRESSED == 'RIGHT') { // Zoom } else { // This call represent `SHOOT` Action. // And it is center of screen matrixEngine.raycaster.checkingProcedure(ev, { clientX: ev.target.width / 2, clientY: ev.target.height / 2 }); } }; WIP calculating for fixing FPS camera view. [1.8.11] New 3dObject property isHUD. If you setup this to the true value object will escape world rotation/translation. Only local translation is active. This is good for HUD Menu in 3d space. Texture editor (runtime): Using Vjs3 with Editor use: App.scene.outsideBox.streamTextures = new Vjs3( "./2DTextureEditor/actual.html", "actualTexture" ); Running Editor Tool npm run run.tex.editor // or npm run te After creating 2d texture direct on page at the end run: npm run build.tex.editor to make build final pack. Imports note we can use any canvas 2d app [anyCanvas] . In examples: porting2d.js [Old VJS] Example of anyCanvas porting_text.js [Vjs3] porting2d_particle.js [Vjs3] It is very powerfull tool! Research Vjs3 source examples at: https://github.com/zlatnaspirala/visualjs On NPM Service npm i visual-js , matrix engine already have visual-js , visual-js-server editor backend part. To show/hide iframe use: App.scene.outsideBox - is any object who have streamTextures LOADED with 2DCANVAS. App.scene.outsideBox.streamTextures.showTextureEditor(); E('HOLDER_STREAMS').style.display = 'none'; Access to the [any] canvas2d program: anyCanvas(path-of-html,name-of-canvas) App.scene.outsideBox.streamTextures = new anyCanvas( "./apps/funny-slot/", "HELLO_WORLD") Live editor [actual.js predefined] Old VJS loading with anyCanvas() Old Live demo: Video and webcam works at: https://maximumroulette.com/webgl2/examples.html Changes: From [1.8.14] Html's Every static file / resource moved to the new folder ./public Improved FPShooter example , added collision box for player. From [1.8.13] MatrixSounds Access object App.sounds. Usage: // Play source audio [single instance]. App.sounds.createAudio('music', 'res/music/background-music.mp3'); // Play simultanius same source audio. App.sounds.createAudio('shoot', 'res/music/single-gunshot.mp3', 5); From [1.8.12] Draw scene list swap items options must be done! From [1.8.0] Added watchify. We have support for real time connections based on webRTC. You must work on https protocol even in localhost. Change in program/manifest net = false if you dont wanna use networking. Node.js Multiplayer Server based on webRTC. Take a look at the folder ./netwotking. Run it: cd networking node matrix.server.js If you wanna in terminal popup then run (bash/work on win also if you have bash) dedicated.sh./ or dedicated.bat. From [1.7.11] No need for: // matrixEngine.Engine.load_shaders('shaders/shaders.html'); Initial Shaders now loads from code (inside engine). No need any action. PWA Fully runned Integrated Add to Home page and regular html5 page options. In same time fixed all autoplay audio and video context construction. It is good to consult pwa test on page.

    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 like it was last updated 2 years ago - Possibly the worst performance - Strange API (in my opinion) and difficult to use - Built in mouse interaction behaves strangely MatterJs http://brm.io/matter-js/ - Also incomplete and lacking constraints - Has a built in mouse constraint but it acts strangely - Updated recently - Simple and easy to use - Doesn't handle stress test well p2.js http://schteppe.github.io/p2.js/ - Complete - Updated within the last few months - Doesn't handle stress test well - Easy to use - Good documentation Box2DWeb https://github.com/hecht-software/box2dweb - Complete - everything you would expect from Box2D - Last updated one or two years ago - Semi-poor documentation - you have use the box2d flash documentation which is fairly thorough but slightly outdated - Much faster and a lot more accurate than the above three libraries. Nape http://napephys.com/ - Complete - lots of features - but isn't very active - Has a great marching squares utility which can convert bitmaps into polygons - Good site and documentation - Easy to use but the pooling get/dispose stuff can be a bit confusing - Similar (or maybe even slight better) performance to Box2DWeb and possibly more accurate - Large - minified it's still 1.7MB The one problem with Nape though is that it isn't really meant for Javascript and I had a lot of trouble getting it set up in Typescript. There were some project to convert it to js and generate definition files but I had to modify them a lot to get something complete that worked for me. I also had to manually convert the debug draw classes from as3 to js and Easeljs. Luckily that only needs to be done once - after that I didn't have any problems using it though. I also tried PhysicsType2D (http://physicstype2d.com/) but couldn't get it to work. Overall I was a bit disappointed; In terms of performance, the 'native' js libraries fell short by a lot compared to the two ported ones, and on top of that they lacked a lot of important features. Even the ported ones didn't perform as well as their Flash/As3 versions - the Nape stress test (you can find it here) which I copied, runs significantly better in flash.

    I need to display a large number (for example 400) of high resolution textures at the same time, for this I used the ParticleContainer from the example - https://pixijs.io/examples/#/demos-basic/particle-container.js. But in the end, I get FPS = 10-15, the more sprites, the lower the FPS, even if you turn off the animation - there is no difference, the image in idle mode also heavily loads the browser, which is why the page scroll is very freezing. - https://codesandbox.io/s/admiring-lamarr-p8bvyf?file=/index.html I could not find a solution anywhere, so I will be grateful for your help.

    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 am trying to make a rotational button that is capable of rotation the sprite by its pivot point in both directions using the mouse movement. Can anyone help me?

    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 I move callAlien function out of the main function it does not work. I am puzzled as to why this is. Can any sage member here tell me why this is? Thanks in advance Crock TheCrock Posts: 2 Joined: 12 Nov 2020, 16:02

    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 body and leg components. 2) Bind the components together via some sort of linked list or maybe even graph based implementation. I'm still learning about graphs and am thinking they're best for this system given compositing more complex sprite sheets will involve layers. Any advised implementations or any kind of information on graphs associated with player creation systems is highly appreciated. I think this is a great opportunity to practice graphs. 3) Next there will be an interface that allows the player to choose the color and textures of each of these components. The player will confirm and submit their design when finished. Now that the player has submitted their design, I'm a bit puzzled about the next step and have a few ideas on composing the data. 4a) Use Phaser api to turn the data into bitmaps? I don't know much about this implementation yet since I'm still learning how to utilize bitmaps and how Phaser handles bitmaps 4b) Composite the items on a canvas and store it in a uri using the canvas to url method. I also lack experience with api but I definitely can see how it would work. 5) Ideally I'll save the data to a database and retrieve them via player credentials. I'm not sure if I'm over complicating things or not so any feedback would be appreciated. I use Phaser but any html5 based idea or solution should be fine.

    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.

    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.

    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 each pixel according to the pixels around it (right, left, down and up), I think I can get the image I want. Is there anyone who can help me with this?

    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, I'm actually proud of it Oh and one more thing, it really does require "some" skills.

    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, 32); this.layer = this.map.createLayer(0); this.layer.resizeWorld(); } }; ``` this is what I pre-load! ``` this.load.image('element-w', 'img/element-w.png'); this.load.image('element-h', 'img/element-h.png'); this.load.tilemap('map', 'img/Teste.csv'); ``` Thank for your help!

    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 pushes object b against object, what happens is object B gets pushed away by object A, but object A doesn’t get pushed away by B meaning, object A will get inside of object B and it will push the object to the top instead of pushing it to the left by activating the wrong collision detection. (as seen in the video). Video which shows the problem: https://www.youtube.com/watch?v=8DHKJNOrO54 (Project files below) I've been trying to solve this problem for awhile now and I just can't find the perfect solution. If anyone would be able to help it'd be great. Thank you game_v1.zip
