  1. How can i lock the angle between two sprites which have a revolute constraint atached to each other? Example i have a arm atached to a body with a revolute constraint and i want to that arm keep up at certain angle, i cant reproduce this : ( 'use strict' game = new Phaser.Game(320, 480, Phaser.AUTO, 'space') mainState = preload: -> game.load.image('body', 'public/images/body.png') game.load.image('arms', 'public/images/arms.png') game.load.image('ground', 'public/images/ground.png') create: -> game.physics.startSystem(Phaser.Physics.P2JS) @chest = game.add.sprite(29,53,'body') @arms = game.add.sprite(8,53,'arms') @ground = game.add.sprite(320,70,'ground') game.physics.p2.enable([@chest, @arms, @ground]) robotCollisionGroup = game.physics.p2.createCollisionGroup() environmentCollisionGroup = game.physics.p2.createCollisionGroup() @ground.body.static = true @ground.body.setCollisionGroup(environmentCollisionGroup) @ground.body.collides(robotCollisionGroup) @chest.body.debug = true @chest.body.setCollisionGroup(robotCollisionGroup) @chest.body.collides(environmentCollisionGroup) @arms.body.debug = true @arms.body.setCollisionGroup(robotCollisionGroup) @arms.body.collides(environmentCollisionGroup) @ground.reset(game.world.centerX, game.world.height) @chest.reset(game.world.centerX, game.world.height - 100) @arms.reset(game.world.centerX, game.world.height - 100) game.physics.p2.gravity.y = 600 @chest.body.collideWorldBounds = true @arms.anchor.setTo(0.5, 0.5) @constraint = game.physics.p2.createRevoluteConstraint(@chest, [ -14, -26.5 ], @arms, [ 0, 28]) @cursors = game.input.keyboard.createCursorKeys() update: -> if @cursors.left.isDown @arms.body.rotateLeft(60) else if @cursors.right.isDown @arms.body.rotateRight(60) else return render: -> game.config.enableDebug = true game.debug.spriteInfo(@arms, 32, 32) # Bootstrap game.state.add('start', mainState) game.state.start('start')
