• I want to make a cannon that activate when a certain variable value > 0.
• So I name the variable ammo with value range from min 0 to max 10.
• For reloading, a certain input will set the ammo value to 10. But ammo value stay at 10 if the input is released (not reverting back to 0).
• When i fire the gun (ignoring fire rate), the ammo value deducted by 1 each time i press/hold fire input until it reached the limit 0.

But the FT on the pic above doesn't work. I tried both input and the ammo value didn't change. Could someone help me?

Edit:

• Answer've been pinned in comment.
• ammo= 10 bugged. But ammo+ 1 works well.
• Turns out the increment/depletion rate is really fast. It's more fitting for duration based than round based firing.
