public Query(callback: (proxy: Box2D.Collision.b2DynamicTreeNode) => boolean, aabb: b2AABB)

see

IBroadPhase.Query

Parameters

public Rebalance(iterations: number)

see

IBroadPhase.Rebalance

Parameters

• iterations: number

public TestOverlap(proxyA: b2DynamicTreeNode, proxyB: b2DynamicTreeNode): boolean

Tests if two proxies overlap.

Parameters

• proxyA: b2DynamicTreeNode

  First proxy to test.

• proxyB: b2DynamicTreeNode

  Second proxy to test.

Returns

boolean

True if the proxyA and proxyB overlap with Fat AABBs, otherwise false.

public UpdatePairs(callback: (userDataA: any, userDataB: any) => void)

Update the pairs. This results in pair callbacks. This can only add pairs.

Parameters

• callback: (userDataA: any, userDataB: any) => void

  Called for all new proxy pairs. param userDataA Proxy A in the pair user data. param userDataB Proxy B in the pair user data.

public Validate()

Validates the dynamic tree. NOTE: this says "todo" in the current Box2DFlash code.
