  1. when a game object belongs to multiple groups that have runChildUpdate enabled, is there a way to make sure its update only runs once per frame? or is there anyway to get around with it?
  2. Hi Guys, I'm having some issues with an emitter that I am trying to attach to a sprite using the addChild method. The emitter should be a child of the player's arm so that it moves and rotates correctly. When I add the emitter to the game without being added as a child it works fine. As soon as I add it as a child to the arm it disappears from the game world. I've played around with a bunch of different coordinates in case it was being moved slightly off screen but I've come to the conclusion that something is going wrong here. I've also run tests in a new state with just a single sprite and an emitter and as soon as I add the emitter asChild of the sprite it is gone. I'm probably missing the thing that is going wrong here, so any help would be appreciated. I'll put my code snippet below if that helps at all create: function() { this.game.stage.backgroundColor = "#000"; this.playerContainer = this.game.add.sprite(300, 600, null); this.player = this.game.add.sprite(0, 0, 'player'); this.player.scale.setTo(0.75); this.backArm = this.game.add.sprite(-10, -180, 'backArm'); this.backArm.scale.setTo(0.75); this.frontArm = this.game.add.sprite(-10, -180, 'frontArm'); this.frontArm.scale.setTo(0.75); this.emitter = this.game.add.emitter(0, 0, 5000); this.emitter.makeParticles('whiteParticle'); this.emitter.minParticleSpeed.setTo(200, 0); this.emitter.maxParticleSpeed.setTo(2000, 0); this.emitter.gravity = 200; this.emitter.lifespan = 0; this.playerContainer.addChild(this.backArm); this.playerContainer.addChild(this.player); this.playerContainer.addChild(this.frontArm); this.frontArm.addChild(this.emitter); this.game.physics.arcade.enable(this.playerContainer); this.game.physics.arcade.enable(this.player); this.playerContainer.body.collideWorldBounds = true; this.player.anchor.setTo(0.5); this.frontArm.anchor.setTo(0.4866, 0.2925); this.backArm.anchor.setTo(0.4866, 0.2925); },

  4. Hi All I've been working on a top down endless runner , where the player jumps from one platform to another and should not leave the screen. How to make a platform move horizontally I'm spawning platforms and adding x and y velocity its working but is it a right of doing it ? if not how to make it look better this.initX = this.x; this.body.velocity.y = -200; platform.prototype.update = function () { if (this.moving) { if (this.x > (this.initX + this.width)) { this.speed = -200; } if (this.x < (this.initX)) { this.speed = 200; } this.body.velocity.x = this.speed; }
  5. I'm currently working on a project myself. Basically as a hobby. Yet I feel it might have potential someday. Therefor I'm willing to invest in myself and this game by hiring help. The goal is to help and guide me. Not to make the game. Obviously I might be helpful if you can provide snippets or classes when I'm really struggling I guess the skills needed are; Phaser 3 TypeScript webpack something about nodejs; express / socket.io I can pay in various ways. Either just cash (transfer, paypal whatever) or help and guidance in things I'm actually good at; (PHP, hosting, devops).
  6. Hello, Just a quick question. I want to kill any emitter particles that overlap with a sprite. I've tried: if(this.game.physics.arcade.overlap(this.emitter, this.sprite)) { this.emitter.removeChildAt(0); //and this.emitter.removeChild(); }
  7. Impossible Snake is a game I've been working on (see posts here and here) and it's now available on the Android playstore. Impossible Snake on Coolmath Games: http://www.coolmath-games.com/0-impossible-snake Impossible Snake on Android Store: https://play.google.com/store/apps/details?id=com.bdrgames.impossiblesnake.ads Impossible Snake on kongregate - http://www.kongregate.com/games/BdRGames/impossible-snake Impossible Snake on newgrounds - http://www.newgrounds.com/portal/view/698543 It is a one-button game, meaning that you control the snake with only single taps on the screen. Every time you tap the snake will toggle between turning clockwise and counter-clockwise. Eat all apples to complete a level, the last three levels are almost impossible.. almost. There is also a VS multiplayer mode, where 2 players can compete on the same device. Player one taps on the top half and player two taps on the bottom half to control their snake. Eat the most apples to win.

    box2d collision filtering with phaser

    Hello, Can anybody please tell me how box2d collision filtering works in JavaScript(box2dweb). I need balls to collide with player but not with other balls. There are example out there but they are in c++ or other language. I am newbie in gaming hence a silly question. Thanks.

    Texture in box2d rope/distance joint

    Hello, Is it possible to give a texture to box2d's rope or distance joint. I can see the joints in draw debug mode, but need something like an actual rope texture. Thanks
  11. I'm trying to create a pie chart with Phaser, using `graphics` to draw each slice of the pie (`graphics.arc(...)`). The problem is that when it renders I get (what I think) an unexpected result. I basically want to draw 3 slices the same size, the code I use looks something like this: function degToRad(degrees) { return (degrees * Math.PI)/180; } var total = 3; var width = 300; for (var i = 0; i < total; i++) { var radius = Math.floor(width / 2); var deg = 360 / total; var start = degToRad(i * deg); var end = degToRad((i + 1) * deg); graphics = game.add.graphics() graphics.beginFill(0xFF0000) graphics.lineStyle(2, 0x000000) graphics.moveTo(0, 0); graphics.arc(0, 0, radius, start, end, false); graphics.endFill() } I've created 3 fiddles to show the difference between a canvas, pixi and phaser based examples, each of them using the same process to draw the slices: canvas: https://jsfiddle.net/oL414v9t/1/ pixi: http://jsfiddle.net/ngma7snq/59/ phaser: https://jsfiddle.net/1ck39fos/1/ Does anyone know why this happens and how can I achieve what I want?
  12. I was trying with Phaser where i saw that this gets some kind of blurred when moving (ingame) Testet it in Canvas & WebGL both had the same result then i tried it to setting `pixelArt` to false in the gameconfig and when i tried it then, it worked smooth, but it seemd that it had activated some kind of antialiasing so it got washed-out but the moving was smooth Phaser 3.8 (Original) Tileset tiles 16x16 (no spaceing / margin) (Extruded) Tileset tiles 16x15 (1px margin / 2px spaceing) Map made with Tiled Vivaldi & Chrome & Windows Edge Tileset Extruder: https://github.com/sporadic-labs/tile-extruder Code Example / Project: https://github.com/hasezoey/phaser-tiled-test Original Question: https://github.com/photonstorm/phaser/issues/3685 (moved to here)
  13. Hi there. Does anyone had a pleasure to build a Facebook Instant Game? I've spent two days trying to scale my Phaser game in the Facebook for Android. Currently scaling works nicely on desktop, in a responsive viewport of the dev console, in the mobile Chrome -- namely everywhere, except the Facebook app. Seems like it just ignores my settings, sprites are displayed at full width, despite the canvas (and game) dimensions are correct. Here are my init and boot scripts, the scaling logic is copypasted from a random gist: // init code FBInstant.initializeAsync().then(function() { FBInstant.setLoadingProgress(50); FBInstant.setLoadingProgress(100); FBInstant.startGameAsync().then(function() { /** Config part */ var FIXED_SIZE = 720; var FIXED_MEASURE = 'Width'; /** Name mapping */ var fixedName = FIXED_MEASURE; var resName = fixedName === 'Height' ? 'Width' : 'Height'; var FIXED_NAME = fixedName.toUpperCase(); var RES_NAME = resName.toUpperCase(); /** Measures of document */ var documentElement = document.documentElement; var documentFixed = window['inner' + fixedName]; var documentRes = window['inner' + resName]; var ratio = documentRes / documentFixed; /** Canvas measures */ var canvasFixed = FIXED_SIZE; var canvasRes = FIXED_SIZE * ratio; var screen = {}; screen['CANVAS_' + FIXED_NAME] = canvasFixed; screen['CANVAS_' + RES_NAME] = canvasRes; console.log(screen.CANVAS_WIDTH); console.log(screen.CANVAS_HEIGHT); game = new Phaser.Game(screen.CANVAS_WIDTH, screen.CANVAS_HEIGHT, Phaser.CANVAS); game.state.add('Boot', Boot); game.state.add('Preload', Preload); game.state.add('GameTitle', GameTitle); game.state.add('Main', Main); game.state.add('GameOver', GameOver); //Start the first state game.state.start('Boot'); }); }); // boot code var Boot = function(game) {}; Boot.prototype = { preload: function() { }, create: function() { this.scale.scaleMode = Phaser.ScaleManager.EXACT_FIT; this.scale.pageAlignHorizontally = true; this.scale.pageAlignVertically = true; this.game.scale.refresh(); this.game.state.start("Preload"); } } Would appreciate any help!
  14. 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.

  16. The Issue Text object is getting cut-off / cropped at the top and sometimes on the bottom, when using a custom font with a narrow width. (screenshot attached) The fonts in question work correctly in every other environment, and even work with HTML canvas and the regular getContext method of adding text. So i'm fairly positive the issue is isolated to Phaser using HTML canvas. Possible Cause I think issue is most likely happening due to the way Phaser/PIXI calculates the height of text from the width of letters. Possibly using the width of the widest letter and assuming the height? I tried to work out what the source code is doing. Current Workaround The only workaround i've found is rebuilding the font and adding a wide margin to each letter (so the letter boundaries are more 'square'), then in Phaser splitting a Text object into individual Text objects for letters and calculating their position based on letter width, and manually subtracting a value to change the letter spacing. But even splitting and repositioning doesn't work that well (with any font, not just thin fonts) i have to calculate separate margins for even thinner letters like 'I', 'i', or 'l', or wide letters like 'm' and 'w'. I would rather not use BitmapText as i need to use different font sizes. Solutions Has anybody else encountered this issue? Found a solution or a better work-around? Thanks.
  17. So i'm trying to switch scenes when a tween is complete, however i get the titular error 'Cannot read property 'start' of undefined' , and i don't know why this is... Here's the code: class StartScreen extends Phaser.Scene{ constructor(){ super({key: "StartScreen"}); } preload() { this.load.image('Logo', 'assets/Logo.png'); this.load.spritesheet('background', 'assets/backs.png' , { frameWidth: 480, frameHeight: 320 }); } create() { this.anims.create({ key: 'stars', frames: this.anims.generateFrameNames('background', { start: 0, end: 127 }), repeat: -1 }); this.add.sprite(1024/2 , 400, 'background').play('stars', true).setScale(2.5); this.logo = this.add.image(1024/2 , 300, 'Logo').setScale(2); this.text = this.add.text(320, 450, 'Push Enter', { font: '50px NES', fill: '#FFF'}); this.enter = this.input.keyboard.addKey(Phaser.Input.Keyboard.KeyCodes.ENTER); } update(){ if(this.enter.isDown){ this.text.destroy(); this.enter = ''; this.tweens.add({ targets: this.logo, y: 150, duration: 2000, onComplete: this.onCompleteHandler }); } } onCompleteHandler(){ this.scene.start('MainMenu'); } } class MainMenu extends Phaser.Scene{ constructor(){ super({key: "MainMenu"}); } preload() { this.load.image('Logo', 'assets/Logo.png'); this.load.spritesheet('background', 'assets/backs.png' , { frameWidth: 480, frameHeight: 320 }); this.anims.create({ key: 'stars', frames: this.anims.generateFrameNames('background', { start: 0, end: 127 }), repeat: -1 }); this.add.sprite(1024/2 , 400, 'background').play('stars', true).setScale(2.5); this.add.image(150 , 300, 'Logo').setScale(2); } create() { } }

    Hi Rich.  @rgk mentioned that you might be able to please add a "patron" badge to my forum profile?  Thanks very much!

I'm making a game where player have to reach the right door and created all the necessary collisions and it works almost perfect, except the call back function wrongDoor. I want to create a dialog line when player collides wrong door and make his velocity = 0 while dialog line is on screen, but I can't. Every time player colldes the door dialog line displays on screen but the player sprite still moves. How can I make him stop on collision with door? All the //commented stuff I've tried and it didn't help. I tried to add this function in Update function but it triggers wrongDoor all the time and displays dialog line again and again from the start of the game. I've tried set velocity = -20000 but it doesn't set -20000 velocity, like it doesn't see the player. On screenshots I press up and right buttons so character moves up and right after wrongDoor triggers.

    Seamless Audio Loops in Phaser

    I'm working on a game with seamless background music and figured I'd share my findings to help others. I'm just using Phaser's standard sound.play('', 0, 1, true) code to play loops. (Have since discovered I can also use sound.loopFull()). I didn't want to mess with outside solutions like seamlessLoop.js, which I'm not sure would work across all browsers anyway. Here's the run down on the file formats: OGG - Good for seamless loops in Firefox and Chrome. M4A - Good for seamless loops in iOS. When I first posted this I thought that I was stuck using the Apple Lossless codec (lossless = huge file sizes) because when I used any other M4A generating codec the resulting audio had blank space added at both ends. I wound up using the fre:ac open source audio converter which adds information for gapless playback according to its developer, who was extremely responsive and helpful (Thanks Robert!). Sure enough, the audio played seamlessly on my iPad with much smaller files. MP3 - Not good for seamless loops, but needed for IE. Even if your MP3 has no silence on either end, when the sound is done playing there will be a small audio gap before it loops. There are some techniques like the ones here that seem promising, so if I can overcome this issue I will post the code. Good for all other use cases because all browsers support it and it has the smallest file size of the three formats when exported with reasonable quality settings. So here's what I'm using to load my seamless loop audio. M4A is in a separate conditional because when I put it as the first option Firefox would load it instead of falling back to OGG and not play the sound. I'm loading all my other sounds as MP3s (in a different code block - not shown) to keep my total file size as low as possible. // load seamless intro audio loadLoop('musicIntro', 'intro_music_loop'); function loadLoop(key, file) { if (game.device.iOS || game.device.macOS) { game.load.audio(key, ['sounds/' + file + '.m4a']); } else { // Firefox and Chrome will use OGG // IE11 will fall back to MP3, which will have a small gap at the end before replaying game.load.audio(key, ['sounds/' + file + '.ogg', 'sounds/' + file + '.mp3']); } } Hope someone finds this helpful

  23. Evening Guys Im working on a game for an iso platform that houses several games. This platform handles the loading of assets and sends them back to my game as base64 assets. Im loading in 3 different types of assets: *XML *Sound *TextureAtlas my questions are these: 1) how can i load and play an audio file recieved as a base64 string? 2) how can i load and create a new XML object from a base64 string? 3) how can i create a game.load.atlasXML from base64 strings? any help or notch in the right direction is appreciated. thanks
  24. I would like to show you the game I am working on: Lier.io: https://lier.io It is a multiplayer shooter 2D (platformer) similar to old games like Liero, Soldat or Worms (a little). Game is written in html5 (Phaser 2) and now has not many features now. Playing: - moving soldier: W, A, S, D (can be changed in settings) - aiming & shoting: mouse (mobile playing is not finished yet) It would be great if you could write me what do you thing about it or maybe what problems do you have with the game.
