Question regarding Mod.

[Almightyzentaco]

I don't fully understand how Mod works. I could really use some help so I know how to fully implement it in the future.

As of now, I have a game with a large frame, and a virtual frame sized 576 by 256.

I have an Always statement running that does this.

Center display at Y=Y( "Active" )-Y( "Active" ) mod 256+128
Center display at X=Y( "Active" )-Y( "Active" ) mod 256+128

This makes the screen pan at one screen intervals, instead of scrolling.

IT works, and I'm happy that it does. But, WHY does it work. My math with mod is a bit fuzzy.

Any help you can give me would be appreciated. Thanks.

Mod = modulo (returns the remainder of a division)

whew. Figured it out.

I wasn't sure what to do when mod returned something less than one.

It just returns the number. NOW I uderstand the equation fully.

Had to make a little program that plugged in MOD and gave answers for it.

Thanks.
