	// when the mouse button is released. See Also: OnMouseDown, OnMouseDrag.
	function OnMouseUp () {
		Debug.Log("Drag ended!");
	}

    void OnMouseUp() {

public class Example(MonoBehaviour):

	def OnMouseUp() as void:
		Debug.Log('Drag ended!')

This function is not called on objects that belong to Ignore Raycast layer.

OnMouseUp can be a co-routine, simply use the yield statement in the function. This event is sent to all scripts attached to the Collider or GUIElement.
