The descriptions I have found do not make it clear whether this clears action lists by performing all actions in the lists or whether it clears the lists by dumping outstanding actions. It is of some interest to me as I have had some actions getting lost on me for what seem to be timing problems, and I am looking for a general solution.

It drops actions.



You probably mean that actions would be performed such that only their results (final consequences) are applied*. Games don't do this normally, because it usually doesn't make sense and may be complex to implement.

* Otherwise we would talk about normal processing of the queue, i.e. you wouldn't call clear() or anything on the queue.

Thank you. That rules that out.
