I had this idea while ingame; if we had health bars in IT,why not both health AND energy bars?
Like,when your running,your energy slowly declines. When you have no energy left,your health starts declining.
Staying still lets your energy fill up slowly,while sitting in shade or laying down lets it go up faster.
If you have no health,you fall to the ground and stay there for about 3 seconds.
(OPTION TO DISABLE.)
Guys,it was only a suggestion for roleplay. o_o
