Is it possible to change a sprite's bounds. I am checking if it overlaps another sprite manually and without physics (http://phaser.io/examples/v2/sprites/overlap-without-physics) and dont need physics in the game at all. But the sprite is like a tree branch for example. Big trunk which I want the player to "overlap" with but not the leaves. If the branch had physics, it was as easy as            branch.body.setSize(850, 10, 100, 75);      But how can I change the bounding box size for a sprite
