BroadPhaseStrategy()

Properties

hashCode → int
The hash code for this object.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited

Methods

computeHeight() → int
Compute the height of the tree.
createProxy(AABB aabb, Object? userData) → int
Create a proxy. Provide a tight fitting AABB and a userData pointer.
destroyProxy(int proxyId) → void
Destroy a proxy
drawTree(DebugDraw draw) → void
fatAABB(int proxyId) → AABB
getAreaRatio() → double
Get the ratio of the sum of the node areas to the root area.
getHeight() → int
Compute the height of the binary tree in O(N) time. Should not be called often.
getMaxBalance() → int
Get the maximum balance of an node in the tree. The balance is the difference in height of the two children of a node.
moveProxy(int proxyId, AABB aabb, Vector2 displacement) → bool
Move a proxy with a swepted AABB. If the proxy has moved outside of its fattened AABB, then the proxy is removed from the tree and re-inserted. Otherwise the function returns immediately. It returns true if the proxy was re-inserted.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
query(TreeCallback callback, AABB aabb) → void
Query an AABB for overlapping proxies. The callback class is called for each proxy that overlaps the supplied AABB.
raycast(TreeRayCastCallback callback, RayCastInput input) → void
Ray-cast against the proxies in the tree. This relies on the callback to perform a exact ray-cast in the case were the proxy contains a shape. The callback also performs the any collision filtering. This has performance roughly equal to k * log(n), where k is the number of collisions and n is the number of proxies in the tree.
toString() → String
A string representation of this object.
inherited
userData(int proxyId) → Object?

Operators

operator ==(Object other) → bool
The equality operator.
