NOTHING IS WORKING

Absolutely nothing is working. The UI is all there, and it is working, but the OnCollisionExit and OnCollisionEnter functions  in unity are somehow not being used at all. They are there in the code and to the best of my knowledge they work, but they are just showing up as unused and the game only works if they work. If I can't get this to work, then the whole game is broken and I still have so much to do... If everything worked, then the game would be pretty much done except for enemy spawning. zi can't get enemy spawning working either because if I try to use the LookAt(target); function in unity, it isn't working.

Long story short: NOTHING WORKS. 

I am so sorry if I do not have a game out on time, but I am trying my hardest to get the game to be actually playable. 

Okay, back to work.
