PNode Methods

The methods of the PNode class are listed below. For a complete list of PNode class members, see the PNode Members topic.

Public Static Methods

Lerp	Linearly interpolates between a and b, based on t. Specifically, it computes Lerp(a, b, t) = a + t*(b - a). This produces a result that changes from a (when t = 0) to b (when t = 1).

RemoveChildren	Overloaded. Remove all the children in the given list from this node’s list of children.
RemoveFromParent	Delete this node by removing it from its parent’s list of children.
RemoveInputEventListener	Removes the specified input event listener so that it no longer receives input events from this node.
Repaint	Mark the area on the screen represented by this node's full bounds as needing a repaint.
RepaintFrom	Pass the given repaint request up the tree, so that any cameras can invalidate that region on their associated canvas.
