Fuctions

function cancelTimersOnNode(node) function cancelTweensOnNode(node) function pauseNodesInTree(node) function resumeNodesInTree(node)

function destroyNode(target) Use this function to remove Quick nodes from the current scene Can pass it to tween:to/from as the onComplete callback (onComplete is automatically passed the owning node as a param) Still need to manually nil any explicit handle we have afterwards Often the nodes have no handle in a game, e.g. ones that were only ever handled with local vars Also cancels all timers and tweens as these would keep running until node is garbage collected.

function destroyNodesInTree(node, destroyRoot) Recursively kill tree of nodes. Top level node is optional Will not nil any values pointing to the nodes, but useful for clenaing up dynamically created nodes that only get tracked via the scene graph.
