Hi guys, I want to create a menu screen with flying asteriods, when they leave the screen, they should appear on the opposite side. I thought this should be done automatically when i use Phaser.Physics.ARCADE, but saidly it doesn't work. My menu looks like this: function menu () { var background = game.add.tileSprite(0, 0, viewportWidth, viewportHeight, 'space'); background.autoScroll(5,+10) // random asteroids var asteroids = game.add.group(); asteroids.enableBody = true; asteroids.physicsBodyType = Phaser.Physics.ARCADE; for (var i = 0; i < 15; i++) { var asteroid = asteroids.create(game.world.randomX, game.world.randomY, 'asteroide', 0); var asteroidSize = Math.random() * (1.1 - 0.5) + 0.5; asteroid.scale.set(asteroidSize, asteroidSize); asteroid.body.velocity.x = getRandomArbitrary(-50, 100); asteroid.body.velocity.y = getRandomArbitrary(-50, 100); asteroid.body.angularVelocity = getRandomArbitrary(-50, 50); asteroid.anchor.setTo(0.5, 0.5); //This allows your sprite to collide with the world bounds like they were rigid objects //asteroid.body.collideWorldBounds=true; //asteroid.body.bounce.setTo(1, 1); }}Thx
