When the player is in the hitbox of an enemy and they stay there, I want the player to take damage every 1.5 seconds or so. When I run a bool thru _process and connect it to on_enter and on_exit signals, the player immediately dies (A timer between hits doesn't seem to work, _process is too fast). When I just make an on_enter to take damage, the player only takes one chunk of damage and nothing else. How should I go by making this?
