//For 3D triggers remove the 2D (e.g. OnTriggerEnter(Collider collision)
/*There are three ways of detecting a Trigger:
-OnTriggerEnter(2D): Activated when player Enters the Collider 
-OnTriggerStay(2D): Activated when player Stays in the Collider
-OnTriggerExit(2D): Activated when player Exits the Collider */
