Hi! I am new to phaser.io and Box2D. I need s.th. like the Angry Birds Catapult, so i decided to use Box2Ds Distance Joint. My questions: 1.) Is it possible to draw a texture over the Joint itself? I need an arm that througs s.th. 2.) In the sample below, i want to remove the Joint by detecting the collision between spriteA and spriteB. Do i have to use the following method? setFixtureContactCallback(fixture, callback, callbackContext)Can s.o. explain me what the "fixture" is? In my example there is a hex number instead of s.th. // A callback to match world boundary contactsship.body.setCategoryPostsolveCallback(0x8000, callback, this); 3.) I want the camera to follow Sprite B until it hits the bottom. Can so. help me with that? <!doctype html><html> <head> <meta charset="UTF-8" /> <title>Phaser Box2D Example</title> <script src="js/phaser-arcade-physics.min.js" type="text/javascript"></script> <script src="js/box2d-plugin-full.min.js" type="text/javascript"></script> </head> <body> <script type="text/javascript">/*** @author Chris Campbell <[email protected]>* @author Richard Davey <[email protected]>* @copyright 2015 Photon Storm Ltd.* @license {@link http://choosealicense.com/licenses/no-license/|No License}* * @description This example requires the Phaser Box2D Plugin to run.* For more details please see http://phaser.io/shop/plugins/box2d*/var game = new Phaser.Game(800, 600, Phaser.CANVAS, 'phaser-example', { preload: preload, create: create, update: update, render: render });function preload() { game.load.image('a', 'assets/sprites/a.png'); game.load.image('b', 'assets/sprites/b.png');}var codeCaption;var bodyAs = [];function create() { game.stage.backgroundColor = '#124184'; // Enable Box2D physics game.physics.startSystem(Phaser.Physics.BOX2D); game.physics.box2d.debugDraw.joints = true; game.physics.box2d.gravity.y = 500; // Simple case with joint anchors at the center of each sprite, and // using the position of the sprites to determine the joint length. // This case uses all parameters.
