  1. Hi @enpu, I just encountered en fixed a small bug in the p2 pulgin. Since it is not open source, I cannot create a pull request so I decided to post it here instead: p2.js line 13876: context.rect( -shape.width / 2 * body.world.ratio, -shape.height / 2 * body.world.ratio, shape.width * body.world.ratio * game.scale, shape.height * body.world.ratio * game.scale ); should be: context.rect( -shape.width / 2 * body.world.ratio * game.scale, -shape.height / 2 * body.world.ratio * game.scale, shape.width * body.world.ratio * game
  2. I have a group that contains a large number of children that are P2 physics objects. When I tween the group the sprites all move correctly, but their collisions occur in the position they were prior to the tween. Is there a good way to update the position of the bodies of all the children? Heres some super simplified code incase it helps: game.physics.startSystem(Phaser.Physics.P2JS); const collisionGroup1 = game.physics.p2.createCollisionGroup(); const collisionGroup2 = game.physics.p2.createCollisionGroup(); const targetsGroup = game.add.group(0,0); const ammoGroup = game.a
  3. Hello, I have a question regarding the Contact Material example (http://phaser.io/examples/v2/p2-physics/contact-material). How is it possible to totally disable bouncing? Even with a restitution of 0, the sprite still bounces a little. Is it necessary to tweak yet another physical property? Or is it unavoidable to have bouncing in P2? Thanks!
  4. Hello, I am quite new to phaser and Tiled. I was wondering if anyone could give me some help with understanding on how to create tilemap collisions that are more than just squares with the p2 physics system. Right now every tile has a square collision box, I would like the collision shape to match the tile shape so that I can have slopes and what not. I am a quite a bit confused on the Tiled to phaser workflow especially on what p2.convertTilemap does and how Tiled's collision editor ties into phaser. So far my code looks like this: preload: function () { this.game.load.image('mapTiles'
  5. Hi, I create a tilemap with 4 layers with one for collisions ( named : collisions ). The layer with pink tiles is my collisions layer, and the tile ID is 515. Then I add a player and active collisions. function preload() { game.load.tilemap('map', gamePath + 'assets/map.json', null, Phaser.Tilemap.TILED_JSON); game.load.image('tiles', gamePath + 'assets/tiles.png'); game.load.spritesheet('cars', gamePath + 'assets/cars.png', 180 / 5, 73); } function create() { game.physics.startSystem(Phaser.Physics.P2JS); map = gam
  6. this.game.physics.startSystem(Phaser.Physics.P2JS); this.game.physics.p2.setImpactEvents(true); var wallCollisionGroup = this.game.physics.p2.createCollisionGroup(); var playerCollisionGroup = this.game.physics.p2.createCollisionGroup(); var doorCollisionGroup = this.game.physics.p2.createCollisionGroup(); this.game.physics.p2.updateBoundsCollisionGroup(); // I've created all the necessary collisions as in expamle: https://phaser.io/examples/v2/p2-physics/collision-groups and it works perfect. player.body.collides(wallCollisionGroup); play
  7. Hello, I am working on a project where i can drag an object in X-direction only(like in a abacus). Is it possible to drag objects in one direction only? I created a simple task where i can move two objects with mouse (link here). The issue is that objects are pushing inside each other if i drag one object to another. I need them to be hard like diamond. Can i achieve that with p2 js or i have to use box2d plugin (like here). Also is box2d will be availabe in phaser v3. Thanks
  8. hi all, I have a problem about the p2 body and sprite positon when I enable a p2 body to a sprite, I use fish.body.setRectangle(fish.width, fish.height); to set the body shape, but the position of body is far away from the sprite, anyone know what is the problem? thx
  9. Hi! What I'm trying to do is have 2 objects: one stuck on screen, and one moving with P2 physics. But from all my testing, what I've gotten down to is that I have 2 choices: 1. No collision between the objects, but able to detect when it goes out of screen or 2. Objects collide but can't detect when goes out of screen So my question is... How do I combine that? This is my code now: var game = new Phaser.Game(800, 600, Phaser.AUTO, 'phaser-example', { preload: preload, create: create }); function preload() { game.load.image('block', 'assets/block.png'); } function c
  10. I'm having an issue with scaling a body down with p2, it would appear that the body has an anchor point that is different to the sprite it is for. This causes the body to move up and left when the sprite is shrunk and the body is scaled to match, thus displacing the sprite... any advice? Note that this only occurs when using a custom poly to create the body
  11. I'm doing P2 physics collisions with: sprite.body.collides(collisionGroups, callback, this); and I'm trying to get some info on the momentum transfer of the collision to calculate damage, but I can't find the right values. What I've tried is to use the velocity difference like this: var impactSquare = Math.pow(p2BodyA.velocity.x - p2BodyB.velocity.x, 2) + Math.pow(p2BodyA.velocity.y - p2BodyB.velocity.y, 2); This works ok, but obviously it gives totally wrong values when the bodies fly towards each other and just barely touch, then deltaV is pretty high but there is basicall
  12. I've played around with P2 physics and created a sprite that has a child attached that can (is supposed to) move freely around the parent. The child should still contribute to collisions with other objects so I gave it a P2 body as well, but it was behaving very odd. A closer look at the debug data revealed that the collision shape and the sprite image are not at the same position o_O in fact the collision shape is located at an absolute position in the world that relates to the relative coordinates between parent and child and does not move at all. Here is an example that you can tr
  13. Hi all, I am recently developing a game which needs a physics bounds like a rounder rectangle. I looked through the docs but find no way to achieve that. Help me, thank you all~
  14. I have a sprite and a body that both rotate towards the pointer. On collision, though, the sprite sometimes gets turned away from the body. The body continues to point towards the mouse but the sprite does not (see image, definitely not the worst that it can be). I haven't found a way to fix this, anyone know how?
  15. Hi everybody, I'm working on my first Phaser based game and so far it's really a lot of fun One thing that keeps giving me some headaches from time to time though is that P2 physics is mostly incompatible with arcade and many tutorials only work with arcade. That seems to start with the sprite bitmaps where everything is rotated 90 degrees Usually I find some workarounds or I've replaced stuff completely like the Weapon plugin, but now I'm facing an issue with collisions where I'm not quite sure what's the best solution: Let's assume we have 2 player sprites and 2 enemy
  16. Hi I'm new to phaser and have been trying to use some of the examples as a starting point. I'm planning on using the "Pick Up Object" example, but restrict the area that the tetris shapes are placed in - so that they land on a solid platform. I would then add 3 x buttons to add more of the shapes onto the screen. Example here: https://phaser.io/examples/v2/p2-physics/pick-up-object Would the best way to achieve this be to build the solid platform using a kinematic sprite as documented here: http://phaser.io/examples/v2/p2-physics/kinematic-body If not, what is the best way defin
  17. I have used this phaser example as a starting point to build a game where shapes are dynamically dropped from the top of the screen and collide with each other: https://phaser.io/examples/v2/p2-physics/pick-up-object What I would like is for the shapes to stop bouncing and vibrating when they collide - but I'm not sure which settings to adjust to achieve this effect (and I've not had much luck with trial and error so far!). I have set gravity like this: game.physics.startSystem(Phaser.Physics.P2JS); game.physics.p2.gravity.y = 6000; Here is my shapes/sprites json fi
  18. So I have been searching a solution for this for 2 days now. I have a character with physics body. This character has sprites attached to it with addChild(). Arms, sword, cloak, range indicator. Range indicator also has a body (only used as sensor/trigger ). However as I found out addChild doesn't work on physics bodies. Sprites move together but I can get Range Indicator's body to move with them. It pretty much sits in the corner. Since addChild() is no go for physics bodies, is there anything else I can use with this? Really trying to avoid writing a custom function to ma
  19. I have a mian body that moves freely on the board. To that body I want to attach a recrangle at a certain offset that would visibly dangle and rotate upon forces affecting the main body. How could I achieve that? I tried a set of springs, but I can't get the desired effect.
  20. When adding a rectangle to a p2 body you have the option to specify a rotation in radians for the shape which it appears is just passed directly on to the p2 shape constructor (hence the need for it to be in radians instead of degrees as are used elsewhere in Phaser). I find that if I use any value other than 0 for a rotation, the shape is properly rotated however drawing of the body via the debug parameter ignores the rotation. Here is a quick codepen illustrating the bug. The character should have a long protrusion coming out the bottom achieved with a rotated rectangle. The phys
  21. Hi all, Been banging my head against the wall for ages with this. Default P2 collision works, I clearShapes() on each sprite to get rid of these boundary boxes and loadPolygon() to get my custom boundaries (defined in sprite_physics.json). However the collision groups appear not to be working as my player sprite goes straight through/under the enemy. Can anyone see where I'm going wrong? // in index.html (function() { var game = new Phaser.Game(1024, 768, Phaser.AUTO, null) game.state.add('Game', Game); game.state.start('Game'); })(); // in game.js var
  22. Hello, I read this simple tutorial for beginners: Adventures in Phaser with TypeScript Physics using the P2 physics engine When two objects are in contact, the event "onBeginContact" must occur. But this does not happen. I moved the code to codepen:
  23. I'm making a game using Phaser, P2 physics and webpack. When it comes to P2 I can not use custom physic shapes because they won't collide with world bounds. I'm using Phaser webpack example template (https://github.com/photonstorm/phaser-ce/tree/master/resources/Project Templates/Webpack) and an example from the website (https://phaser.io/examples/v2/p2-physics/pick-up-object). The point is that when using custom colision shapes, entities won't collide. But they do if I use the default squared shapes or the circle ones that Phaser provide. The game code is simple and you can check
  24. Hi there, I'm working on some P2 physic and getting the attached result, which is weird because the two objects collides without overlapping on one another. I'm I missing something? The code is as follow: game.physics.enable(car, Phaser.Physics.P2JS); car.body.debug = true car.body.angle = car.angle car.body.rotation = car.rotation car.body.addCapsule(70,20) car.body.setCollisionGroup(this.carCollisionGroup); var v =100; var angle = car.body.angle; var vx = v * Math.cos(angle * (Math.PI/180)) var vy = v * Mat
  25. Hi Everyone! Hopefully someone can help with the issue I have faced. I am building a simple racing game and want to implement collision between car and other objects. I am using p2 physics. When I create primitive body objects (e.g. body.setRectangle) collision works fine, but when i use polygon (body.loadPolygon) i have created in PhysicsEditor the car just rides throw these objects without any collisions. I have tried building very simple objects to exclude "holes" in collide, creating collision groups but unfortunately any of these things helped. Attaching my code and a screenshot
