Okay thanks to Bullet Shower demo. (Probably should look at those more often)
What I should have been asking is, how do I activate a script when enter a area, then I activate another when I exit. Since I was able to activate a function when I entered a object, but it would not stop going when I exited an object.
How I solved the issue? I selected my area collision node in player, and then signaled player.gd when I entered an object, and exited. Thus giving me power to activate a script while colliding(Until I exited the object).
