Reference: Simultaneous start overlap/end overlap trigger on mesh: Unreal Engine
Encountered a problem, using npc collision detection, when the npc character just hits the collision box, the on begin overlap and on end overlap events are triggered at the same time.
After investigation and reference, the reason is that the included static mesh objects may have complex collisions. lead to detection errors.
Solution: Delete the collision collision in the collision object (or the object contained in the collision), replace it with a simple collision such as Box Collision, and save it
