Zombie First Person Shooter Update

So I've actually accomplished a lot this week and I'm super happy. The first thing I did was I polished my gameplay by adding a new and more good looking muzzle flash. I also added some bullet imprints so that when the bullets hit a hard surface, it leaves marks. Another thing I did was I made sure the health and ammo pickups would respawn and so that when I'm low on health or ammo, I could immediately replenish it. The process was simple really. The first thing I did was make sure that the start function was on trigger with the player. Next it would add health to the player and turn off the pickup. Finally it would start the respawn timer for any amount of time you put in and then turn on the pickup. The process would reset all the time.
