  1. So I am working on my just general knowledge of how phaser works, I have only done two tutorials. But I think I have a decent grasp on it so far. But I am running into a little problem, I am trying to use the Follower object, so that I don't have to create the vec2 and attach it, but I don't seem to understand the documentation or what it means by "If this Game Object is enabled for physics then this property will contain a reference to a Physics Body." I have scoured the docs for hours. I see how to 'enable' in arcade physics but I cannot find any reference to how with impact physics. I am able to create a body object, and assign it to the game object, as well as assign the the game object to the body, but they do not move in tandem. in fact the body does not move at all. P.S. This is not the only bug, when converting from matter.js to impact.js physics my logic on pausing player movement when the dialog modal broke. but one problem at a time.. P.P.S I know its not the best code //SHIVA path3 = new Phaser.Curves.Path(550, 450); path3.lineTo(450, 450); path3.lineTo(450, 505); path3.lineTo(550, 505); path3.lineTo(550, 450); path3.lineTo(450, 450); shiva = this.add.follower(path3, 550, 450, 'shiva'); //Phaser.GameObjects.BuildGameObject(this, Phaser.GameObjects.PathFollower) //this.game.physics.enable(shiva, impact); shivaBody = this.impact.add.body(550, 450, 16, 12); //TRYING DIFFERENT WAS TO SET BODY //shivaBody.setOffset(550, 450, 16, 12); shiva.body = shivaBody; shivaBody.setGameObject(shiva); shiva.name = "shiva"; shiva.setRotation(); shiva.depth = 30; //ALT WAY TO GET NAME //shiva.name = "shiva"; shiva.setData(npc, true); shiva.setData("name", "shiva"); npcBodies[2] = shivaBody; npcs.add(shiva); shiva.startFollow({ ease: 'Linear', duration:6000, yoyo:true, repeat: -1, _delay: 200, delay: 100 }); P.P.P.S I also tried this.physics.world.enable(shiva); this.impact.world.enable(shiva); dialog_plugin.js game.js index.html city.json
  2. in this game i need physics for multiple objects for a group its fine to enable p2 bt whenever i tried to enable p2 for player with this line game.physics.p2.enable(player, false); my screen goes black why is this happening ??? var game = new Phaser.Game(window.innerWidth * window.devicePixelRatio, window.innerHeight * window.devicePixelRatio, Phaser.AUTO, '', { preload: preload, create: create, update: update}); var player; var world; var blink; var rocketangel; var rocketdirection; var rocketSpeedDelta; var rocketradius; var platforms; var scoreText; var playerangle; var scaleRatio; var score; var asteroid; scaleRatio = window.devicePixelRatio / 2; //load images or files before game starts function preload() { game.load.image('background', 'assets/game/background.png'); game.load.image('world', 'assets/game/world.png'); game.load.image('player', 'assets/game/player.png'); game.load.image('blink', 'assets/game/blink.png'); game.load.image('asteroid', 'assets/game/asteroid.png'); } //create all the images ans things on the screen function create() { score=0; rocketangel = 0; rocketdirection = 1; rocketSpeedDelta = 0.002; rocketradius = 170; playerangle=60; // A simple background for our game game.add.sprite(0, 0, 'background'); // We're going to be using physics, so enable the Arcade Physics system game.physics.startSystem(Phaser.Physics.P2JS); // Turn on impact events for the world, without this we get no collision callbacks game.physics.p2.setImpactEvents(true); game.physics.p2.restitution = 0.8; // Create our collision groups.
