I honestly think the cash system is much easier to make using Ply's Mod... but that may just be me.
I've made this system countless times, and it's never as hard or as complicated as the one Conjured made for the official variable system.
Here's what you'll need to do:
- Declare (dim) a variable for cash in the setuplevel.fpi script (usually in the state 0 section)
- Add to or subtract from that variable when needed
There, you have a cash system. You can even set up a numeric HUD (similar to the numerics for health and lives) to show how much cash you have. You can find out how to do this in the ReadMe document that comes with the Mod. It's very easy to do and after you make the HUD, it'll update itself automatically when the variable changes.
The one and only,
