Also not sure about the multiple hooks/unhooks, I don't know how SDKHooks handles that. Maybe a global bool MAXPLAYERS+1 to check when it's hooked / unhooked. I guess theres multiple ways to tackle this would need to test.

Just tested on the tank at that moment.
Just want use this only for the tank for now.


This should look better and there is still no more than 50 lines)
