How do i stop an attribute going into minus?

Ok so i have an attribute for ammo and when you fire, it deducts one. When you get to zero you need to press the reload button. The problem i have is that if you press fire when on zero it goes to minus 1, how can i make it just stop on zero and obviously wont fire until you hit reload? Thanks in advance

Hey,

Wrap it in a Rule like this:

Rule
When game.ammo > 0
Change Attribute: game.ammo To: game.ammo - 1

also..not 100% but I think if you make the attribute an 'Index' value...it will be 0 or greater and never go below.

Think that would work....take a look at the attributes page on:

ORBZ

ammo = max(ammo-1, 0)
