Hi @ErenHatchet,
Yes, you can use the Other Actor pin of the EventActorBeingOverlap to check if the overlap is your player. There are a few ways of doing this. One of the simplest ways is to use tags.
In your player BP, search for tags in the details panel. Add one such as “Player” under the Tags array. Then from the EventActorBeingOverlap node drag out and use the Actor Has Tag node. Use a branch node to check the condition and put the code under the true path.
