Hello. I'm trying to follow http://gamemechanicexplorer.com/#homingmissiles-1 but my missiles end up pointing in the wrong direction all the time. So I simplified and removed basically everything but the rotation of the bullet. But even with a centered stationary bullet it ends up facing in another direction than where the pointer is. Missile.prototype.update = function() { var targetAngle = this.game.math.angleBetween( this.x, this.y, this.game.input.activePointer.x, this.game.input.activePointer.y ); this.rotation = targetAngle;}; I'm using 2.0.3 Any thoughts on what might be wrong here?
