When describing the RetryUntilSuccesful Node on the BehaviorTree.CPP page it is stated that the Retry node will repeat ticking the child up to N times if the child returns FAILURE. Currently however, if the child returns FAILURE the whole tree starts again from root. This could cause problems or at least be inefficient e.g. if a robot first moves back to an old position before going to the current position and trying an action again. So, I was wondering if the latter is the desired behavior of RetryUntilSuccessful or if in fact only the child should be ticked N times?
