I'm trying to set up my trees to be choppable as long as the player character is within their interaction area (so that is_interactable becomes true) and is clicking the left mouse button. Everything seems to work, except that the function _on_InteractionArea_area_entered doesn't seem to detect my PlayerCharacter's Area2D node, so is_interactable never becomes true unless I manually set it to true.

Additionally, PlayerCharacter's InteractionArea is set to monitorable, Tree's InteractionArea is set to monitoring.
EDIT: PlayerCharacter's Collision Layer is 4, Mask is 1, 2, 3, 5 and 6.

I'm very new to programming, so feel free to point out any mistake, big or small!
EDIT2: Got area_entered to work by fixing the Collision Layers and Masks for both Area2Ds (whoops), but now it's not detecting my mouse clicks anymore.
