setBounds(x, y, width, height, left, right, top, bottom, setCollisionGroup)

Sets the bounds of the Physics world to match the given world pixel dimensions. You can optionally set which 'walls' to create: left, right, top or bottom. If none of the walls are given it will default to use the walls settings it had previously. I.e. if you previously told it to not have the left or right walls, and you then adjust the world size the newly created bounds will also not have the left and right walls. Explicitly state them in the parameters to override this.

Parameters:

Name	Type	Argument	Default	Description
`x`	number			The x coordinate of the top-left corner of the bounds.
`y`	number			The y coordinate of the top-left corner of the bounds.
`width`	number			The width of the bounds.
`height`	number			The height of the bounds.
`left`	boolean	<optional>	true	If true will create the left bounds wall.
`right`	boolean	<optional>	true	If true will create the right bounds wall.
`top`	boolean	<optional>	true	If true will create the top bounds wall.
`bottom`	boolean	<optional>	true	If true will create the bottom bounds wall.
`setCollisionGroup`	boolean	<optional>	true	If true the Bounds will be set to use its own Collision Group.

setImpactEvents(state)

Impact event handling is disabled by default. Enable it before any impact events will be dispatched. In a busy world hundreds of impact events can be generated every step, so only enable this if you cannot do what you need via beginContact or collision masks.

Parameters:

Name	Type	Description
`state`	boolean	Set to true to enable impact events, or false to disable.

setMaterial(material, bodies)

Sets the given Material against all Shapes owned by all the Bodies in the given array.

Parameters:

Name	Type	Description
`material`	Phaser.Physics.P2.Material	The Material to be applied to the given Bodies.
`bodies`	array.<Phaser.Physics.P2.Body>	An Array of Body objects that the given Material will be set on.

setPostBroadphaseCallback(callback, context)

Sets a callback to be fired after the Broadphase has collected collision pairs in the world. Just because a pair exists it doesn't mean they will collide, just that they potentially could do. If your calback returns false the pair will be removed from the narrowphase. This will stop them testing for collision this step. Returning true from the callback will ensure they are checked in the narrowphase.

Parameters:

Name	Type	Description
`callback`	function	The callback that will receive the postBroadphase event data. It must return a boolean. Set to null to disable an existing callback.
`context`	object	The context under which the callback will be fired.

toJSON() → {object}

Converts the current world into a JSON object.

Returns:

object -

A JSON representation of the world.

update()

Internal P2 update loop.

Source - physics/p2/World.js, line 755

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.
