• world
• aabb
• result

Inherited from Broadphase but overwritten in src/collision/SAPBroadphase.js:287

Returns all the bodies within an AABB.

Parameters:

Returns:

• bi
• bj
• axisIndex

Defined in src/collision/SAPBroadphase.js:204

Check if the bounds of two bodies overlap, along the given SAP axis.

Parameters:

Returns:

• a

Defined in src/collision/SAPBroadphase.js:103

Parameters:

• a Array

Returns:

• a

Inherited from Broadphase: src/collision/Broadphase.js:73

Check if the bounding volumes of two bodies intersect.

Parameters:

• bodyA Body
• bodyB Body
• pairs1 Array
• pairs2 Array

• pairs1
• pairs2

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

Removes duplicate pairs from the pair arrays.

Parameters:

• pairs1 Array
• pairs2 Array

• bodyA
• bodyB

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

Check if a body pair needs to be intersection tested at all.

Parameters:

• bodyA Body
• bodyB Body

Returns:

• world

Inherited from Broadphase but overwritten in src/collision/SAPBroadphase.js:57

Change the world

Parameters:

• world World

Defined in src/collision/SAPBroadphase.js:31

Axis to sort the bodies along. Set to 0 for x axis, and 1 for y axis. For best performance, choose an axis that the bodies are spread out more on.

Defined in src/collision/SAPBroadphase.js:17

List of bodies currently in the broadphase.

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

Set to true if the objects in the world moved.

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.

Inherited from Broadphase but overwritten in src/collision/SAPBroadphase.js:24

The world to search in.
