Hello.
I have a counter, called Counter1, which is supposed to show the ammo of my character. Whenever my character moves over an ammocrate, the ammo is increased by 5, which i have already made the counter show. What i need to do is make it display the total ammo amount. So instead of starting at 0 and ijncreasing by 5 every time i pick up an ammocrate, it starts at 5, increases by 5 when i pick up a crate, and decreases by 1 every time i shoot ( use an ammo )
I have the folllowing code for the counter
I have the actor Ditzel, which is the character that removes the ammo crate and gains ammo.
notice the hitAnAmmo method and the ammo variable - is it possible for me to make the counter show whatever value that ammo variable has?
This is the code for my world, in which the counter is called.
Thanks very much :)
