This is where I'm rendering the primitives, in the switch is where I'm displaying the HP bar
the HP is at 100 its just an int that hold the HP and I've loaded 11 different textures for the health
starting from hp 0,1,2,3,4,5,6,7,8,9,10. The calculation for subtracting from the HP bar is elsewhere, what I'm having
trouble with is getting the HP bar to either follow a player model on the screen or to get the bar to follow the viewport so that it follows the screen on the bottom right hand corner, I'm not sure how to approach this problem.
