Hi Everyone, I am currently working on my first game using Phaser but I am having an issue with using accelerateToXY. I am developing a space invaders type game and for the bullet code I am following parts of the tanks example to try and fire a bullet. Here is the line it seems to be stuck on: bullet.rotation = game.physics.arcade.accelerateToXY('playerBullet', this.player.x, this.player.y + 10, 40, 100, 100);However when trying to fire the bullet I get the following error message in the console from phaser.min.js: "Uncaught TypeError: Cannot read property 'acceleration' of undefined" If anyone could offer any assistance with this issue it would be greatly appreciated Thanks, Jaymeh Edit: I am currently running phaser version 2.0.6
