Is there a guide for using tweens/easing with P2 physics bodies? I tried using body.x like so: var tween = game.add.tween(jar.body).to( { x: 384 }, 2000, Phaser.Easing.Linear.Out, true);It works, but there's a risk of tunneling with fast movement - do I need to call some kind of update function? Alternatively I tried using body.velocity: var tween = game.add.tween(jar.body.velocity).to( { x: 384 }, 2000, Phaser.Easing.Linear.Out, true);This works better it seems, but how do I make movements to precise coordinates onscreen?
