You've got a point, but as long it's no flamewar :)
GA, then.

yeah, i find this stuff interesting, so why stop?

Also- with parrallax scrolling, you have to keep seperate varaibles for ewach layer...but you can also do some cool stuff. Like in Moira, (and this will also be in other games I do, cause it's cool) the fog on the bottom of the screen is constantly moving, which is simple- you just need to check to see if the map is at it's edge, and then draw again from the begining, thusly getting infinite parrallax scrolling that is constantly moving...

For repeating background tiles, I think what I did was simply modulus the current screen position by the width of the background tile, and then add that (or subtract it, or something) to the starting point value for drawing the background (then draw it as many times as is needed to fill the screen up).

And then to have it scroll at a slower or faster speed, I would simply modulus by (background width<<1) for double speed or (background width>>1) for half-speed. At least I think so, I havent peeked into that code in forever.

Using seperate values certainly works though, especially if you want it to constantly scroll. I think I put another variable called "offset" in for that. I dunno, but I'm starting to think your method is simpler hehe.

no, not repeating tiles, like having seperate maps for parrallax scriolling (it looks nicer, allows more detail, and having something like a parrallax scrolling map that was in zelda on the snes on the moantians (the tiny towns and clouds...very cool). It works better this way...and having it constantly scroll adn lead to cool effects :)

Oh, yeah, good point. You would DEFINATELY need to do it your way for that to work hehe
