  • pairs2 Array

makePairsUnique

(
  • pairs1
  • pairs2
)

Inherited from Broadphase: src/collision/Broadphase.js:135

  • pairs2 Array

needBroadphaseCollision

(
  • bodyA
  • bodyB
)
Bool

Inherited from Broadphase: src/collision/Broadphase.js:48

Parameters:

Returns:

Bool:

setWorld

(
  • world
)

Inherited from Broadphase: src/collision/Broadphase.js:175

To be implemented by subcasses

Parameters:

Properties

dirty

Boolean

Inherited from Broadphase: src/collision/Broadphase.js:30

Set to true if the objects in the world moved.

useBoundingBoxes

Boolean

Inherited from Broadphase: src/collision/Broadphase.js:23

If set to true, the broadphase uses bounding boxes for intersection test, else it uses bounding spheres.

world

World

Inherited from Broadphase: src/collision/Broadphase.js:16

The world to search for collisions in.
