Hi I have applied a freecamera to my project. camera = new BABYLON.FreeCamera("FreeCamera", new BABYLON.Vector3(-40, cameraHeight,-132), scene); I have applied gravity to it so that it won't fly ie: camera.applyGravity = true; I have given it a constant height (cameraHeight) scene.registerBeforeRender(function () { scene.activeCamera.position.y = cameraHeight; }); Now the problem is that when I move the mouse up and down along the Y axis the camera rotates (in essence on the x-axis). So the camera is elevated and it's like flying.I have checked the ESPILIT demo and it's the same problem (Espilit.babylon has camera gravity enabled). So is there a command which limits the rotation of the free camera up and down (or left and right) ? If I need to calculate the rotation in registerBeforeRender then my 2nd question, can I stop a camera?

So I have a scene that I got from another person that I've exported from Blender into Babylon, but whenever I try to render the scene dynamically it falls straight down. Changing the physics of the scene in Babylon doesn't seem to work, nor does creating a ground object with collisions enabled. I've attached the scene in question; what am I missing? example.babylon

Dokia Dokia is a challenging platformer in which you have to change the direction of gravity in order to proceed. This game contains 4 worlds with 10 levels each! Try to reach the hole in all of them. It may be hard, but it is worth it! It may take a while to get used to the way the gravity-switching works, but that is part of the game. You can play the game here: https://www.kongregate.com/games/Diamonax/dokia I hope you like it!

On colliding with a box the camera sees through the box. In the following PGs I have used camera.ellipsoidOffset to place the camera at the middle of the ellipsoid (line 86) and used two viewposts. The lower viewport uses a second camera slightly above and behind the main camera. I have added a cone to represent the main camera with an ellipsoid around it. I have also customized the key input behaviour. Up and down arrow keys move the camera forward and backward , left and right arrow keys turn the camera. I have also lowered the speed of the camera. Face a box and walk towards it until it collides and will not move forward. You can see through the box. https://www.babylonjs-playground.com/#DHMD1C There is also another mystery as the camera moves forward it rises upward as can be seen by the spheres parent to the main camera. At the start you can only see the top of the sphere then as it moves the whole of the sphere becomes visible. You can see the changes in y in the console. Perhaps they are to do with my customised input manager but no - I removed it and did a PG with default behaviour same problem https://www.babylonjs-playground.com/#DHMD1C#1 TLDR; These issues came to light as I am in the middle of writing a PBT (playground based tutorial) for camera collisions, gravity and customized camera inputs and have been following this thread with interest. Last week I never noticed the gravity issue or the see through the box issue. Now whether changes instigated as a result of this thread has altered some property of the camera or I am mis-remembering what I saw a week ago or was just too focused on the code for the PBT I am not sure but the mystery is there now.

Hi, Can I somehow (with physics plugin Oimo.js) set different gravity for different meshes? For example I want to simulate environment in water and I want to have there buoyancy. https://www.babylonjs-playground.com/#2B84TV#7 Thanks a lot for your advice.

Hello evryone, i try to better understand collisions & mehs interactions. I found this demo on the babylon.js 101 docs: http://www.babylon.actifgames.com/moveCharacter/ https://doc.babylonjs.com/babylon101/cameras,_mesh_collisions_and_gravity Is it possible to get the source code ?

Hello! In Phaser ( particularly Phaser CE ) I can't find something like Wind Resistance for objects. And start thinking how to implement my own version: create(){ game.physics.startSystem(Phaser.Physics.P2JS); game.physics.p2.gravity.y = 100; this.car = game.add.sprite(32, 32, "car"); game.physics.p2.enable(this.car,false); this.car.body.windResistance = 0.4; } update(){ if(this.car.body.windResistance && this.car.body.velocity.y > this.car.body.windResistance ){ this.car.body.velocity.y-= this.car.body.windResistance; } } With this I can't use big numbers for windResistance, only between 0 and 1. What do you guys think??

Schubi Action and skill game in spirit of Thrust and Space Taxi. Direct link: http://www.beppigames.de/play/schubi/index.html Games page: http://www.beppigames.de/schubi/index.html Homepage (find my other games there, for each there is a html5 version): http://www.beppigames.de PREFACE If puzzled by the first level please read "WHAT TO DO IN LEVEL 1" below. May take 30 seconds to 10 minutes to pickup and develop necessary skills. Difficulty level is nasty but easier than in the aforementioned classics. To solve all levels probably takes a week. If you happen to solve level 28, notify (the only level I failed at). MISSION Pilot your little yellow ship and load all trucks with cargo at a construction site (level) within the shift duration of 180 seconds. Cargo is picked up by flying over a dispenser (the circular object). This hooks cargo to the ship and a truck is loaded by ejecting the hooked cargo and hitting the truck with it. - 30 largely varying levels, playable in any order. - game within game principle, e.g. level 30 is a racing game. You may find some references to e.g. Asteroids, Thrust, Space Taxi and Cut The Rope in other levels. ON THE IMPLEMENTATION Wrote this as my first game in 2012. This html5 version is a mixture of transpiled javascript (emscripten) and normal javascript. No engines were used, everything was written from scratch (physics, collision detection,...). CONTROLS Keyboard only: A - turn ship left S - turn ship right K - thrust L - eject hooked cargo (keys above can be redefined in KEYS submenu) Quit a level / back in menu: B, Backspace or ESC Menu navigation and selection: Arrow keys and Return WHAT TO DO IN LEVEL 1 AND HOW TO DEVELOP THE NECESSARY BASIC SKILLS Your ship cannot cross the red white striped barrier, only cargo can. First fly around using keys A,S,K. If you got that fly over the dispenser (the green circular object). Now that the cargo is hooked to the ship fly some circles, halfcircles and watch the cargo gyrating around the ship. If you got that eject the cargo with L. Study its flying path. Pick up more cargo and practice throwing (hurling) the cargo so it reaches the trucks beyond the barrier. If you loaded all trucks, congratulations, you developed necessary skills for this game. One further useful skill to be developed is rotating the cargo to the ships nose (and keeping it there by maneuvering) so you can push it. Described in the game but overlooked: The yellow black striped areas are explosive ones. Do not touch them, neither with the ship nor drop cargo there. BROWSER REQUIREMENTS WebGL capable browser, may not work with MS Edge. There is no loading bar for the initial preloading of music. Be patient. There is also an Android version available from itch.io in a free to play bundle (see www.beppigames.de/schubi for links).

Hello, I'm currently building a scene where a person walks through a room. There are several objects in the room. When I run and run against a large mesh, I collide and can't get through (it's wanted). When I walk towards a low (low height) mesh, I'm suddenly reset, probably to the old position. Camera position: [0.1.2, -2.25] Camera ellipsoid: [0.5,0.59,0.5] Scene gravity: [0, -9.81, 0] Bottom is at y = 0 How do I set the camera's collisionsbox correctly to run on the floor and not get the effect of low meshes? Thank you.

I see the docs of the Body class http://phaser.io/docs/2.6.2/Phaser.Physics.Arcade.Body.html But i am not sure which would be the right property to change. I have two balloons falling down and they might both at the same time or one after the other, hit my rectangle. The problem is, both objects stop moving after they hit the rectangle. i am sure this has to do something with physics. As if the vertical(y coordinate) velocity gets set to 0 when they hit the rectangle. Here is a sample code: graphics = si.gameObject.add.sprite(boxX, boxY, si.ImageAssetKeys.BALLOON_ANIM_ATLAS, 0); floatingAnim = graphics.animations.add('floating', si.GraphicsUtility.getFloatingAnimArray(), 30, true); splashAnim = graphics.animations.add('splash', si.GraphicsUtility.getSplashAnimArray(), 30, false); splashAnim.onComplete.add(si.LetterBox.splashComplete, this); graphics.animations.play('floating'); balloon.graphics = graphics; balloon.graphics.anchor.setTo(0.5, 0.5); balloon.graphics.body.checkCollision.up = false; balloon.graphics.body.checkCollision.left = false; balloon.graphics.body.checkCollision.right = false; balloon.graphics.body.checkCollision.down = true; balloon.graphics.body.velocity.y = velocity; balloon.graphics.allowGravity = false; balloon.graphics.allowRotation = false; Which body property should I change to prevent the stop in movement of balloons?

Hi there, my first post! I'm learning how to use Phaser by following a cool tutorial by Wild . At a moment he explains us how to move our player by using keyboard input. And everything works fine but the jump mouvement =/ And I don't understand why! (my browser console says nothing). Nothing happens when I press the up button. Here is my code if someone is willing to explain me a bit what's wrong? in the create player.animations.add('idle',[0,1],1,true); player.animations.add('jump',[2],1,true); player.animations.add('run',[3,4,5,6,7,8],7,true); this.physics.arcade.enable(player); this.camera.follow(player); player.body.collideWorldBounds = true; controls = { right: this.input.keyboard.addKey(Phaser.Keyboard.RIGHT), left: this.input.keyboard.addKey(Phaser.Keyboard.LEFT), up: this.input.keyboard.addKey(Phaser.Keyboard.UP), }; And in the update function: this.physics.arcade.collide(player,layer); player.body.velocity.x=0; if (controls.right.isDown){ player.animations.play('run'); player.scale.setTo(1,1); player.body.velocity.x += playerSpeed; } if (controls.left.isDown){ player.animations.play('run'); player.scale.setTo(-1,1); player.body.velocity.x -= playerSpeed; } if (controls.up.isDown && (player.body.onFloor() || player.body.touching.down) && this.time.now > jumpTimer){ player.body.velocity.y = -600; jumpTimer = this.time.now + 750; player.animations.play('jump'); } if (player.body.velocity.x==0 && player.body.velocity.y==0){ player.animations.play('idle'); } } I don't know if any other information would be useful?

Hi, I imported a mesh and then separated it into two objects. Basically a wheel and a stand for the wheel. And I want the axle for the wheel to fall onto the stand and allow me to spin the wheel. My problem is that I can't get the physics to work right. I either drop things through the floor or gravity doesn't work at all, depending on the different engines and things I've tried. I'm new to babylonjs so perhaps I'm doing wrong something that's simple to see. My code is at http://www.babylonjs-playground.com/#2I8LFS#2 If anyone can see what I'm doing wrong, I'd much appreciate it!

I thought this would be a simple fix, but so far can't figure it out at all. I have something I call trapledges that is going to fall in the y direction when colliding with player. However, I can not get them to stop moving in the x direction if the player touch the side of them. In my code I have a commented out if test in the update function. I've tried it out both there and in the else if test where the trapledges get made. also tried out different things in the test as changing velocity.x = 0; to for example gravity = 0; or trapLedge.immovable.x = true; and so on. Still won't stop floating to the side if the player touch the sides of the ledge, instead of landing ontop of it. Added two jpgs of the game, with an arrow showing how the ledge move. A cross to show which way I want the ledge to stop move. var playState = { create: function() { for (i = 0; i < 100; i++) { var trapRandomizer = (Math.random() * 0.6) + 0.3; var randomYPos = (Math.random() * 200) + 290; var randomXSize = (Math.random() * 0.6) + 0.3; var randomYSize =(Math.random() * 0.8) + 0.6; //console.log("x: " + randomXSize + "Ran" + trapRandomizer) if (trapRandomizer > 0.4) { var ledge = platforms.create(ledgeXPos, randomYPos, "ground"); ledge.scale.setTo(randomXSize, randomYSize); ledge.body.immovable = true; } else if (trapRandomizer <= 0.4) { console.log("Trapledge"); var trapLedge = trapPlatforms.create(ledgeXPos, randomYPos, "ground"); trapLedge.scale.setTo(randomXSize, randomYSize); trapLedge.body.immovable = false; } } update: function() { /* if (game.physics.arcade.collide(trapPlatforms, player)) { trapPlatforms.body.velocity.x = 0; trapPlatforms.body.velocity.y = 300; }*/ },

Hi @all again, is there a way to change the gravity for certain space? Case 01: I want for example that the player or other objects can fly to space. So if specific distance has been reached from the ground, the gravity should decrease with rising distance, until null. Case 02: If the player or other objects goes into a hidden area/space/box, the gravity for all objects in there is different to the world gravity (scene.gravity). Thanks for ideas.

Hi there, I'm creating a simple platform game where you can shoot enemies. I've applied game.physics.arcade.gravity.y = 1000; But this seems to now affect my weapon class and bullets too! How do I set my weapons or bullets to NOT be affected by gravity? Here's the code I've used for reference: var playState = { //code to make assets goes here create: function(){ /*-- creating player --*/ game.add.sprite(0, 0, 'background'); game.physics.arcade.gravity.y = 1000; //Do not enable, need to fix gravity. this.player = game.add.sprite(game.width/2, 780, 'player'); this.player.anchor.setTo(0.5, 0.5); game.physics.arcade.enable(this.player); this.player.body.gravity.y = 1500; this.player.body.bounce.set(0.3); this.player.body.collideWorldBounds = true; this.player.cursor = game.input.keyboard.createCursorKeys(); this.player.fireButton = game.input.keyboard.addKey(Phaser.Keyboard.SPACEBAR); this.player.hp = 100; this.player.weapon = game.add.weapon(30, 'bullet'); // this.player.weapon.enableBody = true; this.player.weapon.bulletKillType = Phaser.Weapon.KILL_WORLD_BOUNDS; this.player.weapon.bullets.setAll('body.gravity.y', 0); this.player.weapon.bulletSpeed = 850; this.player.weapon.fireRate = 200; this.player.weapon.trackSprite(this.player);

Hello Happy New Year everyone I'm a french student which has a homework to make with phaser. I have then started to work and learn to use it and finally tried to make little game thanks the help of the many tutorials and examples on the web but i'm quite bad and i'm finally stuck at this point. http://195.83.128.55/~mmi15c02/int/phaser.php For now the problem is to create many little alien (it will be change later) at the right of the screen and make them go to the left in a repetitive way but i tried one thousand method and always failed as you can see my last attempt XD if someone know how to do pls help (sry for the english). the actual code : <script type="text/javascript" src="js/phaser.js"></script> <script type="text/javascript"> var game = new Phaser.Game(1000, 400, Phaser.AUTO, '', { preload: preload, create: create, update: update }); function preload() { game.load.image('alien', 'assets/alien.png'); game.load.image('background', 'assets/background.png'); game.load.image('bullet', 'assets/bullet.png'); game.load.spritesheet('vaisseau', 'assets/vaisseau.png', 32, 48); } var sprites; var vaisseau; var alien; var background; var cursors; var bullets; var bulletTime = 0; function create() { game.physics.startSystem(Phaser.Physics.ARCADE); background = game.add.tileSprite(0, 0, 1000, 400, 'background'); bullets = game.add.group(); bullets.enableBody = true; bullets.physicsBodyType = Phaser.Physics.ARCADE; bullets.createMultiple(30, 'bullet'); bullets.setAll('anchor.x', 0.5); bullets.setAll('anchor.y', 0.75); bullets.setAll('outOfBoundsKill', true); bullets.setAll('checkWorldBounds', true); vaisseau = game.add.sprite(100, 200, 'vaisseau'); vaisseau.anchor.setTo(0.5, 0.5); game.physics.enable(vaisseau, Phaser.Physics.ARCADE); vaisseau.body.collideWorldBounds = true; cursors = game.input.keyboard.createCursorKeys(); fireButton = game.input.keyboard.addKey(Phaser.Keyboard.SPACEBAR); sprites = game.add.group(); game.time.events.loop(300, createSprite, this); } function createSprite() { var alien = sprites.create(1000, game.world.randomY, 'alien'); } function fireBullet () { if (game.time.now > bulletTime){ bullet = bullets.getFirstExists(false); if (bullet){ bullet.reset(vaisseau.x, vaisseau.y + 8); bullet.body.velocity.x = 400; bulletTime = game.time.now + 400; } } } function update() { background.tilePosition.x -= 2; if (vaisseau.alive){ vaisseau.body.velocity.setTo(0, 0); if (cursors.down.isDown){ vaisseau.body.velocity.y = 200; }else if (cursors.up.isDown){ vaisseau.body.velocity.y = -200; }else if (cursors.left.isDown){ vaisseau.body.velocity.x = -200; }else if (cursors.right.isDown){ vaisseau.body.velocity.x = 200; }if (fireButton.isDown){ fireBullet(); } } sprites.x -= 5; } </script>

Hi. I'm trying to make my first game with Phaser and I'm trying to get some physics working - global gravity. I'm not sure whats going on but somethings not working: vaultage.game.prototype = { create : function() { this.background = this.game.add.tileSprite(0, 0, this.game.width, 360, 'background'); this.background.autoScroll(-100, 0); this.background = this.game.add.tileSprite(0, 290, this.game.width, 8, 'ground'); this.background.autoScroll(-180, 0); this.player = this.add.sprite(30, 230, 'player'); this.player.animations.add('run'); this.player.animations.play('run', 10, true); // physics engine this.game.physics.startSystem(Phaser.Physics.P2JS); // gravity this.game.physics.p2.gravity.y = 400; }, based on a couple tutorials I've been following I was expecting for the 'ground' to fall, but it does not. I'm still really new to Phaser and kinda new to JS, so i figure I'm overlooking something simple. I actually only need gravity on the player sprite so if you could suggest how to go about that I would appreciate in but would be happy just to get some gravity of any kind to start with. Thank you in advance for your help.

Hello Everybody!! I present to you, the BEST multiplayer casual space shooter game on the Internet today! -->WHAT IS IT ABOUT?? 1. It is a 2 dimensions multiplayer space game that is gravity based. 2. Your spaceship has stats that you can improve by either collecting items in space or by destroying other player's ship. 3. Everything in the game has mass, and newtonian physics has influence over everything. Entities are attracted to each other according to roughly (mass1*mass2)/distance^2. 4. Your ship has two basic stats that determine its defense, its armor amount and shield amount 5. Shield recharges according to the amount of shield you have left, you can add to your total shield amount by acquiring the right item floating in space. 6. Armor do not recharge, every unit of armor you add to your ship add a certain amount of mass to your ship. Your ranking is determined by your total MASS! 7. You can repair your armor if you have enough unit of "armor repairer". Can be found floating in space. 8. The force of your propulsion system can be modified by item you find in space. The bigger you get, the more propulsion power you need to accelerate. 9. The rate of fire (RoF) can also be increased by item found in space, as well as the damage that each of your projectile !! //---------------------------------------------------------------------------------------- UPDATES ----------------------------------------------------------------------------------------------// 1. 28/11/2016 ---> Addition of the Flash Bomb, uses shield and deals damage to surrounding area according to how much shield you had when you fired it. //-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------// VISIT AT www.gravitymelee.com !!!----> Feel free to ask any question!!!!!!!! <----!!! --> IS THIS GAME HTML5?? - yes, the front end is mostly an html5 canvas and javascript, the back-end is node.js.

Hello, When I am using free camera and attached controls, camera is falling only for about 1 second and than stops. I have to press control key to begin falling again. Can increase this duration or give camera instruction to fall (something like moveWithCollisions )? http://www.babylonjs-playground.com/#21AD8N Thanks!

So I've been working on a game (First Person Shooter): http://filmsbykris.com/scripts/metal_bullets One of the problems I have now is with the gravity. In stead of having people look through the mess of the code for that project, I've simplified it here: http://tinyurl.com/pfgjthp That scene might take a minute to load. It creates 3,000 random spheres in the scene. You can make the camera jump by clicking the mouse. The problem is this. When the scene gets complicated, and the frame rate drops, gravity slows down. So, in this example scene with the 3,000 spheres I get 60fps in chrome on my desktop. When I jump, it lasts less then a second with my current settings. But, on my laptop (or in a browser that renders slower - example: Firefox) were I get 20fps in that scene, the jump lasts about 4 seconds. This becomes a real problem in my game because on slower machines you can fly across the board with one jump, If I change the settings and adjust them for slower computers, then on faster computers the jump time is to short. Is there a better way of doing this? Thanks for any help.

I am building a basketball game. I cannot get the ball to stop sticking to the rim colliders. When I was running p2 physics, the ball would simply bounce off the rim colliders as expected, but now, everytime the ball touches the rim colliders, it slows down movement rapidly and doesn't bounce or fall as expected. I think I might be missing a property setting somewhere. I set the rim colliders (leftMarker + rightMarker) to be immovable in create() but I'm not sure what else I need. I don't understand why the colliders stick to each other! Any help is appreciated!

Hello I got a 3dModel of an elevator. I trigger a button for it's position with the following code: myMesh.actionManager.registerAction(new BABYLON.InterpolateValueAction(BABYLON.ActionManager.OnPickTrigger, myMesh,"position.y",-2.6, 1000)) //down .then(new BABYLON.InterpolateValueAction(BABYLON.ActionManager.OnPickTrigger, myMesh,"position.y",0.001, 1000)); //up Witch works great! Accept when my char wants to get up again, he is falling through the ground, - the mesh. Few workarounds that come into my head, like check the state of the "event" an apply new gravity or new cam position. What's the easiest one? Any suggestions are highly appreciated! Best

I'm working on a game with a tilemap and arcade physics. The gravity is set to 1000 for the player and enemies movements and interacting which all work fine. However, when I add a particle emitter the particles also fall down? I've tried setting emitter.gravity to "0" but that doesn't help. The only thing that stops the particles from falling is disabling the line that sets game.physics.arcade.gravity.y, which is not what I want because the gravity is needed for the game. So my question is: how to disable the gravity of emitter particles? I've created a fiddle with example code here: https://jsfiddle.net/pjjL7ecu/1/ Btw this is similar to this old thread which doesn't have a clear answer, as far as I can tell. function create() { // set stage physics game.stage.backgroundColor = 0x808080; game.physics.startSystem(Phaser.Physics.ARCADE); game.physics.arcade.gravity.y = 1000; // add particle emmiter emitter = game.add.emitter(0, 0, 200); // x=0, y=0, maxParticles=200 emitter.makeParticles('particles', [0, 1, 2, 3]); //emitter.setXSpeed(-120, +120); //emitter.setYSpeed(-120, +120); emitter.setXSpeed(0, 0); // testing; particles should not move at all emitter.setYSpeed(0, 0); emitter.setRotation(0, 0); emitter.gravity = 0; // no gravity on particles // test sparkles will still fall down emitter.x = CANVAS_WIDTH / 2; emitter.y = CANVAS_HEIGHT / 2; emitter.start(true, 2000, null, 10); // explode=true, lifespan=800, freq=null, quantity=10 } function render() { var testparticle = emitter.getFirstExists(); if (testparticle) game.debug.bodyInfo(testparticle, 10, 10); }

Hi all, very new to Phaser and I'm trying to basically make a colour switch kind of game. So I am using p2 physics for the rotating arcs so I can add collision detection later. I had these arcs as graphics in the game but then couldn't add physics to them so they are now sprites in a group call wheel. I have the pivot point of the group set to (85,85). I don't know why but this number works, the sprites are 170x170 but when I try to give the group a pivot point such as (0.5,0.5) it doesn't work I've even tried (0.25,0.25) to try and recreate the (85,85) pivot point. I am trying to do this because when I apply the p2 gravity to the game the wheels pivot point does not move so the wheels rotation gets bigger and bigger. If anyone has a possible solution to this or an alternative method to go about this then please reply! I'm so desperate right now it's not even funny.

i would like to show you guys my first browser game, Planet boom, it's in an incomplete state since i was working on it for a workshop, but of course you can check out the code (which is kinda crappy) and if you like the concept you can probably contribute to the project, i'm always willing to join teams or collaborate on projects.
