Phaser Class: P2

How to deactivate bodies during simulation. Possible modes are: World.NO_SLEEPING, World.BODY_SLEEPING and World.ISLAND_SLEEPING. If sleeping is enabled, you might need to wake up the bodies if they fall asleep when they shouldn't. If you want to enable sleeping in the world, but want to disable it for a particular body, see Body.allowSleep.

updateBoundsCollisionGroup(setCollisionGroup)

By default the World will be set to collide everything with everything. The bounds of the world is a Body with 4 shapes, one for each face. If you start to use your own collision groups then your objects will no longer collide with the bounds. To fix this you need to adjust the bounds to use its own collision group first BEFORE changing your Sprites collision group.

Parameters:

Name	Type	Argument	Default	Description
`setCollisionGroup`	boolean	<optional>	true	If true the Bounds will be set to use its own Collision Group.
