In a previous recipe, we handled user input to allow the user to drag an object. In this example, we see a bowl filled with pieces of fruit that can be dragged across the screen. A piece of fruit does not collide with another piece of fruit.
enum { //Collision bits for filtering
CB_GROUND = 1<<0,
CB_FRUIT = 1<<2,
CB_BOWL = 1<<4
};
