Source - physics/p2/World.js, line 1079

removeSpring(spring) → {Phaser.Physics.P2.Spring}

Removes a Spring from the world.

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.

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.

Source - physics/p2/World.js, line 303

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.

Source - physics/p2/World.js, line 1110

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.

Source - physics/p2/World.js, line 323

toJSON() → {object}

Converts the current world into a JSON object.

Returns:
object -

A JSON representation of the world.

Source - physics/p2/World.js, line 1306

update()

Internal P2 update loop.

Source - physics/p2/World.js, line 667

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.
