Ok so this is a little code for a game.Now what im having trouble figuring out is
how would i add 5 str or dex or chr?
the 20 is how much mana it takes to activate
and the 80 is how much mana you have.

You say that as though it means something. Add them to what? (Or alternatively, do you mean add five to them, whatever they are.) If you have something, and you want to add five to it, you do whatever += 5.

Well see when you Activate A jutsu Its going to cost mana , tahts what i dont get how to do.

I edited my coding please take a second look If you dot mind=)

So then presumably you only want to do whatever it is you're doing if there's enough mana, so you would need to check first. Then deduct from mana.
