TI-Basic Moving Sprite Question

[KermMartian]

There's two possible solutions to your problem. The first solution is to use Pt instead of Pxl commands: PtOn, PtOff, etc (PointOn, PointOff). These take the x and y coordinates of the graphscreen instead of x,y pixel values. The other option, and probably the faster of the two, is every time you change your x and y coordinates, check it they're less than 0 or greater than the width or height. If one is less than zero, set it equal to zero. If it's greater than the width-1 or height-1, set it to width-1 or height-1.

TI-89 guys... 83+ stuff might help give him theories, but not actual code.

http://tifreakware.calcgames.org/tutorials/89/

That should help a bit... Though the tutorials in that section are kinda... sparse

Look here for Assembly Resources.

There's definitely not enough TI-89 info around the community.

I think both C and C++ would be helpful for understanding some of the logical and flow structures of ASM, since they're essentially the same except for a few syntactical and librarical changes in C++/

TiLem (z80 series) and TiEmu (68k series) are undoubtedly superior alternatives to VTI in terms of ease-of-use, features, and accuracy of emulation.
