  1. Hello, I'm having a bit of trouble working out how I can dynamically change the animation speed, while still maintaining the current frame the animation is up to when I make the change. See demo here http://www.babylonjs-playground.com/#IBU2W7#2 When the speed changes I would hope that the current frame was not affected, so I can ramp down to a period of slow motion then resume back to normal speed I suspect I might be mutating the wrong variable to change the speed, but I can't work out what might fix it
  2. Hello, I am experiminting with the Virtual Joysticks Camera and I have a scene that is relatively large. when I use the left joystick to move the camera it moves really slow, I can't figure out how to change the speed of the left joystick. The right joystick(camera rotation) rotates just fine. Thanks for the help!
  3. Speed and Frame Rate

    I am trying to fix the speed and framerate for Link if someone have any idea for doing computations, speed = function(framerate) for example Here is the code : http://codepen.io/featuresmega/pen/ALKLEj var game; var map; var layer, layer1, layer2; var player; var cursors; game = new Phaser.Game(800, 600, Phaser.CANVAS, 'Zelda Mysteries of PhaserIO', { preload: preload, create: create, update: update, render: render }); function preload() { game.load.tilemap('zelda', 'http://crossorigin.me/http://asciimulation.link/assets/tiles/zelda.json', null, Phaser.Tilemap.TILED_JSON); game.load.image('tiles', 'http://crossorigin.me/http://asciimulation.link/assets/tiles/light_world.tiles.png'); game.load.spritesheet('link', 'http://crossorigin.me/http://asciimulation.link/assets/sprites/walking.tunic.png', 24, 32, 55); } function create() { //World map = game.add.tilemap('zelda'); map.addTilesetImage('light_world.tiles', 'tiles'); currentTile = map.getTile(2, 3); layer = map.createLayer('Calque de Tile 1'); layer = map.createLayer('Calque 2'); //Player player = game.add.sprite(50, 150, 'link'); player.scale.set(2); player.smoothed = false; player.animations.add('right', [0, 1, 2, 3, 4, 5, 6, 7], 20, false); player.animations.add('up', [12, 13, 14, 15, 16, 17, 18], 8, false); player.animations.add('left', [33, 34, 35, 36, 37, 38, 39, 40], 8, false); player.animations.add('down', [44, 45, 46, 47, 48, 49, 50, 51], 8, false); game.physics.enable(player, Phaser.Physics.ARCADE); game.camera.follow(player); cursors = game.input.keyboard.createCursorKeys(); } function update() { player.body.velocity.x = 0; player.body.velocity.y = 0; var speed = 200; if (cursors.right.isDown) { game.camera.x += 4; player.body.velocity.x = +speed; player.animations.play('right'); } else if (cursors.up.isDown) { game.camera.y -= 4; player.body.velocity.y = -speed; player.animations.play('up'); } else if (cursors.left.isDown) { game.camera.x -= 4; player.body.velocity.x = -speed; player.animations.play('left'); } else if (cursors.down.isDown) { game.camera.y += 4; player.body.velocity.y = +speed; player.animations.play('down'); } else { player.animations.stop(); } } function render() { game.debug.spriteInfo(player, 20, 32); }

  5. Different player speed

    Hello, Don't know if it is a bug but players with different FPS move by different speed. I use FreeCamera. I have got 60 FPS and I move about three times slower then other player with 20 FPS. That's weird because players with lower FPS should move slowly. I guess there is some speed compensating code. Also if player is for some time in another browser window and switch to game immediately holding move button he move for a while by huge speed. Sorry for my English. Thanks!
  6. Does Babylon has any compression of .babylon file and assets? Or it doesn't. And we should enable gzip compression on server settings. Is this the only solution to compress assets and all other resources to server client our babylon.js game? greetings ian
  7. Is there a big efficiency difference, in terms of game speed/smoothness and memory usage between using a small png for entities sprites VS using a big png and scaling it down with javascript ingame?
  8. Hello! I have a tween animation: var speed = (playerInfoObject.engine.speed != null) ? playerInfoObject.engine.speed * 15 : 0;var tween1 = game.add.tween(myShip).to({ x: galaxyGate.x, y: galaxyGate.y}, speed, Phaser.Easing.Linear.None, true);This is an animation for a ship movement For example: I have a big tileSprite (space). When the tween starts in different points of this tileSprite the ship's speed is different too. I need to make it the same from all it's starts points. I have already tried smth. but that didn't help me =( var position = {x: myShip.x, y: myShip.y}; var target = {x: galaxyGate.x, y: galaxyGate.y}; var speed = 5000; var counter = 0; var timePrev = Date.now(); var tween = game.add.tween(myShip) .to(target , speed) .onUpdateCallback(function(){ myShip.x = myShip.x; myShip.y = myShip.y; counter++; if(counter === 100){ tween.stop(); var timeNow = Date.now(); var timeDiff = timeNow - timePrev; speed = speed - timeDiff; tween.to( target, speed) tween.start(); } }) .start();Thank you in advance!!!
  9. So how can I set random speed for every object, so the acquired speed will stay? Now I have defined speed as constant, but it also increases the speed of every object. SPEED = 3; this.enemies.forEachAlive(function(enemy){ enemy.body.velocity.x += Math.random(SPEED + (SPEED/2)); }); I tried first with Tanks -example style, where is defined max and min speed, but i didn't work.
  10. Hi guys, After several months and tens of hours of work I released the v2 of my first game PAWs! Some of the new key features I’ve added: - Ten new cool characters that can be unlocked for FREE. Each character that you unlock comes with one or more extra lives. - I've replaced the numbers and signs with shapes for a better visibility and also because some people don't like numbers. - I’ve changed the rewards system to just hearts (that fill the health bar) and stars (which give x2 bonus for a limited time). I think it's less confusing this way. - I’ve replaced most of the sounds with cooler ones. - Full menu makeover. - Lots of optimizations. - Made game much more intuitive.

Thank you!
  11. Hi all! I'm coding a multiplayer game with server verification and the first thing you need when doing so, is a deterministic environment. And my issue is that velocity seems not to be even remotely reliable... I made a sandbox to illustrate my issue : http://phaser.io/sandbox/edit/vLcJZUDX You can see that from frame to frame, the delta x (in px/s) is really different. I could set the x and y myself (without using velocity), but then I would loose the collision detection, which I want to use, of course. Am I using velocity wrong? Is my sandbox poorly done? Thanks a lot guys!

  14. Maintain speed after collision

    I have 2 bouncing balls which are bouncing off world borders and also off each other. The balls do maintain their speed when bouncing off the world borders but they lose their speed when bouncing off each other. I'd like them to maintain their speed after they collide with each other. I realise this is quite against the physics but is this doable? Here it the game implemented with p2 physics http://finspin.github.io/bubble-game/version-2/ and the code below. And here is the same game implemented with arcade engine where balls are bouncing without losing the speed http://finspin.github.io/bubble-game/version-1/. I switched from the arcade engine to p2 after I learned arcade can't handle collision of circular objects. var game = new Phaser.Game(480, 640, Phaser.AUTO, 'Bubble Game', { preload: preload, create: create, update: update, render: render});var b1, b2, bubble1, bubble2;function preload() {}function create() { game.stage.backgroundColor = "#000"; game.physics.startSystem(Phaser.Physics.P2JS); game.physics.p2.setImpactEvents(true); var bubbleCollisionGroup = game.physics.p2.createCollisionGroup(); game.physics.p2.updateBoundsCollisionGroup(); b1 = game.add.graphics(); b1.beginFill(0xFF0000, 1); b1.drawCircle(0, 0, 50); bubble1 = game.add.sprite(game.world.width - 380, game.world.height - 50); bubble1.addChild(b1); bubble1.anchor.setTo(0.5, 0.5); b2 = game.add.graphics(); b2.beginFill(0xFFFFFF, 1); b2.drawCircle(0, 0, 50); bubble2 = game.add.sprite(game.world.width - 245, game.world.height - 50); bubble2.addChild(b2); bubble2.anchor.setTo(0.5, 0.5); bubbles = game.add.group(); bubbles.add(bubble1); bubbles.add(bubble2); game.physics.p2.enable(bubbles); bubbles.forEach(function (bubble) { bubble.body.setCircle(50); bubble.body.setCollisionGroup(bubbleCollisionGroup); bubble.body.collides([bubbleCollisionGroup, bubbleCollisionGroup]); }); var bubbleMaterial = game.physics.p2.createMaterial('bubbleMaterial'); var worldMaterial = game.physics.p2.createMaterial('worldMaterial'); bubble1.body.setMaterial(bubbleMaterial); bubble2.body.setMaterial(bubbleMaterial); game.physics.p2.setWorldMaterial(worldMaterial, true, true, true, true); var contactMaterial = game.physics.p2.createContactMaterial(bubbleMaterial, worldMaterial); contactMaterial.friction = 0; contactMaterial.restitution = 1.0; bubble1.body.damping = 0; bubble1.body.velocity.x = 200; bubble1.body.velocity.y = -200; bubble2.body.damping = 0; bubble2.body.velocity.x = -100; bubble2.body.velocity.y = 250;}function update() {}function render() {}
  15. It is using WebGL in both cases, and I have turned on "use hardware acceleration" in Firefox (latest version). I see the same difference in the mobile versions of Chrome and Firefox I made my site again from scratch when 3.0 came out, and the version of the site which uses the old Pixi still performs similarly in both browsers. Is there an acknowledged difference in Pixi 3.0's ability to perform in Firefox vs. Chrome?
  16. i have create mini game with collision system on it. the game about the ball bouncing on moveable player's box. all code is working well. the problem is while i move the box and hit the ball it become faster. i want the speed stay as it what ever happen to the ball. here is my code: game.physics.arcade.enable(box);game.physics.arcade.enable(ball); box.body.immovable = true; box.anchor.setTo(0.5, 0.5); ball.anchor.setTo(0.5, 0.5); ball.body.collideWorldBounds = true; ball.body.bounce.setTo(1, 1);ball.body.velocity.setTo(150, -150); this http://phaser.io/examples/v2/arcade-physics/bounce-knock as reference, try to push the ball using the alien, it is what i mean by the speed is changing.
  17. Hi, I want to follow a sprite with another, but when the first sprite move quickly, the second is shifted. It is visible on the screen and in the logs (x/y position in each iteration of the update function). When the first sprite slow down, the shift is reduced. When it stop, the sprite are at the same position (it’s normal). How to do the positions of the two elements remain the same every time? I have make a live example here : http://jsbin.com/kipayexoqadu/4/edit?js,output Lose focus to do “pause” and watch positions and images. Sorry for my bad english. My example code : var red_ball=null, green_ball=null;var MainState={ preload: function(){ this.load.image('red_ball', 'http://examples.phaser.io/assets/sprites/red_ball.png'); this.load.image('green_ball', 'http://examples.phaser.io/assets/sprites/green_ball.png'); }, create:function() { this.time.advancedTiming = true; this.physics.startSystem(Phaser.Physics.P2JS); this.physics.p2.setImpactEvents(true); this.physics.p2.defaultRestitution = 0.8; red_ball = this.add.sprite(100, 100, 'red_ball'); this.physics.p2.enable(red_ball); red_ball.enableBody = true; red_ball.physicsBodyType = Phaser.Physics.P2JS; red_ball.scale.set(2); red_ball.body.setCircle(8); red_ball.body.collideWorldBounds = true; red_ball.body.fixedRotation = true; red_ball.anchor.setTo(0.5, 0.5); red_ball.body.angle = 90; red_ball.body.moveForward(3000); green_ball = this.add.sprite(100, 100, 'green_ball'); green_ball.scale.set(2); green_ball.anchor.setTo(0.5, 0.5); }, update: function(){ green_ball.x = red_ball.x; green_ball.y = red_ball.y; }, render: function() { this.game.debug.text(this.game.time.fps || '--', 2, 14, "#00ff00"); this.game.debug.text('Green ball: x: ' + green_ball.x + ' - y: ' + green_ball.y, 2, 30, "#00ff00"); this.game.debug.text('Red ball: x: ' + red_ball.x + ' - y: ' + red_ball.y, 2, 46, "#00ff00"); }};var game = new Phaser.Game(500, 500, Phaser.CANVAS, 'phaser-example', MainState); Thanks ! Edit: i have update my jsbin link example + a new screenshot to see the shifted:
  18. Hi All!, I am looking for a method to get a dramatic performance increase (frame per second) on fullscreen with webGL (I am working now with three.js framework) This is my game: http://tario.github.io/quadnet I made it adapt to window size on browser resize events, so, you can test reducing the window to tiny size to get huge performance, and setting the window to great size (e.g. fullscreen) will make the game VERY SLOW, ok , this make sense since a small enough window will set the resolution to 640x480 or whatever, and (in my case) setting the window to fullscreen will set the resolution to 1600x900... Of course I know render the game in higher screen resolution will be make it slow since there is much more fragments to process by GPU (640x480 -> about 307200 fragments, 1600x900 -> about 1440000 fragments). But now, I am looking a way to render the game smooth (near 60fps) on fullscreen, even sacrifying quality, one approach I tried is to set the resolution of canvas (and rendering) to half widht, half height, (e.g. 800x450) and using CSS to stretch the canvas to cover all the window (all of this on fullscreen), and it didn't improve I hear about methods of postproessing via scaling (e.g. rendering on 800x450, then doing an scale) but I don't know how to use them Thanks in advance!
  19. Hi, I'm newbie in Phaser (excuse my english)... Currently I'm developing pinball game. I have created flippers (paddle) via revolute constraints and ball in P2 physics... Everything works perfect but I need to make flippers more powerfull when they hit to ball (I need ball acceleration)... currently CreatePaddle = function(game,x,y, side) { Phaser.Group.call(this, game); this.side = side; this.flipped = false; this.sprite_two = game.add.sprite(x, y, 'paddle'); game.physics.p2.enable(this.sprite_two, true); //this.sprite_two.body.clearShapes(); if(side == 'right') { this.sprite_two.body.loadPolygon('physicsData', 'paddle2'); this.maxAngle = 30; this.pivotOffsetX = 50; this.sprite_two.scale.x *= -1; this.pivotPoint = this.game.add.sprite(this.sprite_two.position.x + this.pivotOffsetX, this.sprite_two.position.y); this.pivotOffsetX = 50; } else { this.sprite_two.body.loadPolygon('physicsData', 'paddle'); this.maxAngle = -30; this.pivotOffsetX = -50; this.pivotPoint = this.game.add.sprite(this.sprite_two.position.x + this.pivotOffsetX, this.sprite_two.position.y); } this.game.physics.p2.enable(this.pivotPoint); this.pivotPoint.body.static = true; this.pivotPoint.body.clearCollision(true,true); this.flipperConstraint = this.game.physics.p2.createRevoluteConstraint(this.sprite_two, [this.pivotOffsetX, 0], this.pivotPoint, [0, 5]); this.flipperConstraint.upperLimitEnabled = true; this.flipperConstraint.lowerLimitEnabled = true; return this.flipperConstraint;}Ball is created like this: //ball - circlecircle = game.add.sprite(470, 300, 'circle');circle.anchor.setTo(0.5, 0.5);game.physics.p2.enable(circle, false);circle.body.setCircle(16);circle.body.fixedRotation = true;Flippers are loaded like this: this.paddle1 = new CreatePaddle(game, 270, 2390, 'left');this.paddle2 = new CreatePaddle(game, 460, 2390, 'right');But how can I add more power to ball which collide with my flipper (paddle) ? Should I create custom material for flipper or is there easier way? Thanks for answers.
  20. TileMaps changing

    Hi. I've just been profiling my game and it has been *awfully* slow to cleanup a part of a tilemap. There wasn't any indication of why it would be slow; 20x20 was snappy. 100x100 was a nightmare. And I was updating 390 tiles. Now I'm not using physics. Tilemap code updates all layers when things change so it was a loop of 100x100x390 updates in TileMap.calculateFaces. Unsure if I was doing something wrong or some such, but I don't think this is a desired functionality. I'd say - do this at most once per frame. What I did was hack it by adding "return; //collision isn't used here." in the first line. I do my collisions outside of phaser (I anyway need to store my map data and objects logic for load/save) so that's probably why this was not needed. Anyway - It'd be nice to make it simple to update multiple layers and keep the calculateFaces from firing. Maybe something like: TileMap.preventRecalculate(doPrevent); and if it's prevented and changed, you just mark it for update. Simple, I think. Thanks for the freat framework, Tim.
  21. Hi there little felas, I stumbled upon two ways to code with Phaser in OOP. Each one are diferent in how to code, and in how to structure your game. The first is the familiar http://codevinsky.ghost.io/phaser-2-0-tutorial-flappy-bird-part-1/ Let's call it "flappy tutorial". And the second is the http://createdineden.com/blog/2014/may/01/multi-platform-games-with-phaserjs/ And this we call it "not-flappy tutorial". Well, the flappy tutorial uses a simple and easy to understand way to structure the game. He uses the objects/classes ass a simple module of code to be added to the main code, without any complication and any work to think about. In the not-flappy tutorial, I took a few seconds to understand how it works. He makes the object a extention of the Phaser.Sprite to determinate that object ass a sprite, and to add to the game, you have to add ass a existing object through Phaser.Game.add.existing and add the object ass a Phaser object. Cool huh? So, witch one of these ways make our game run smoothly? Take less time to execute? May the force be with us, so we can live long and prosper...
  22. Fast

    Hey guys, I'm not sure if it is still allowed to post non flappy bird clones, but here is my latest game: Fast. It's kind of a work in progress, as I'm trying to polish it as much as possible, but the game is pretty much done. I made Fast for Clay.io's Got Game HTML5 competition. I was really proud of my game from last year, even though I didn't win anything, so I decided that this might be the occasion to create a new cool game. All you have to do is to drive as long as possible without destroying your car, but I still tried to make it a little bit more than a simple scoring game (though I love these). You can play 4 game modes at the moment: Free: basic endless scoring mode. The only goal is to go as far as possible.Time attack: same thing, but with a two-minute limit.No crash: in this mode, you have to go as far as possible without a single scratch on your car. Hit one single obstacle, and the game is over.Challenge: this mode is a little different. Everytime you play, you are given three challenges. You can only complete these objectives. Once you complete one of them, it is replaced by a new one If you guys have any feedback (good or bad), I'd be happy to read it and try to improve on (even on the graphics). You can play the game at http://fast.remvst.com/ Have fun
  23. I'm not sure if it's exactly Babylon.js question, but here's the situation I can't deal with for a while now... I have a box (player), that has velocity and etc. things, right? While the box doesn't touch (intersects) anything it's — player.velocityY -= worldGravity, when it touches something — player.velocityY = 0 and no worldGravity applies anymore, right? Things work as they should. The problem is that -velocityY is so high that player gets inside of the floor and only then stops. I tried everything I could: intersects for meshes, for bounding boxes, points, even rays infos (distance and etc.); but nothing helps because -velocityY is higher than collision code runs (I'm not sure but that's my only though, since less velocity works just fine). Player's velocity by Y gets between -8 and 0, while gravity is 0.25. Any thoughts? player.y++ while intersects isn't an option, of course.
  24. Pixel Grid Sprite Tile Movement

    I am trying to create a top-down game with movement constrained to a grid (think Pokemon Red/Blue movement). I have successfully imported a tilemap (32x32 pixel tiles) into my game, and I have set up tile collisions using setCollisionBetween() and physics.collide() for a player-controlled sprite. Currently I am adjusting body.velocity properties on keyboard input to move the player sprite, which works fine but is not really what I want. What I would like to do is to move the player sprite 1 tile (32 pixels) in the appropriate direction so that it always aligns to the tiled grid. I have tried updating the sprite's body.x and body.y values, but when I do this the player sprite seems to ignore all collision logic with the tilemap layer tiles set with setCollisionBetween(). So in short, how can I move a sprite x pixels every key press while still limiting the speed at which the sprite can cover a certain distance (as well as ensuring collisions still work)?
  25. For point-and-click game, or another one, that suggests to use only clicks, is it better to use standard 'onmousedown' event, or do touch events have smaller/bigger response time? Or it depends only on framerate and the best one is to put one of them in RAF call? Will RAF calls go faster, if framerate will be low, for example, <15?
