Hello. I am a beginner in UE (Unreal Engine). I am using UE for reinforcement learning. Currently, I am having an issue with the player acquiring rewards. I want the player to acquire a reward only once when a certain collision overlaps with a checkpoint using “OnComponentBeginOverlap”, but it is not working correctly. What I have done is as follows:
1: Using “OnComponentBeginOverlap”, I set the “overlap” variable to True when the player overlaps with a checkpoint. (First image) 2: Using “OnComponentEndOverlap”, I set the “overlap” variable to False when the overlap ends. (Second image) 3: In the “check reward” function, if the “overlap” variable is True, it flows to “do once”, and sets the “checkpoint overlap” variable to True only once (this causes a reward to be acquired elsewhere). The “do once” resets when the “overlap” variable becomes anything other than True, and the “checkpoint overlap” is also set to False. So, after touching a checkpoint once, the “checkpoint overlap” should not become True again until the “EndOverlap”, but it keeps becoming True while touching the checkpoint. What I want is for the “checkpoint overlap” to become True only once until the “EndOverlap”. (Third image) 4: I have connected the “check reward” function to the “event tick”.
To reiterate, what I want is for the “checkpoint overlap” to become True only once until the “EndOverlap”. If there is a better way, I would appreciate if you could let me know.
