V200/68k Snake

That was one of the reasons to make snake, it has trolling potential

Anyways, I'm stuck because I can't detect where the snake has been or reliably erase the snake. I could use a matrix but that would get quite memory consuming...

maybe you can use a list?

Maybe, I've tried with a version that stores the last five places the snake has passed, and it went to about 25% speed...

and I don't know if I can increase the size of the list. If it gets too long then memory might run out

Maybe look at other snake games for other calcs to get an idea?

yeah, that was my plan.

I think making it on the graph screen would be easier, because the pxltest can see where the snake has been

Nice to see you back into calculator programming. Have you gotten any luck implementing collision detection for this game yet? On the graph screen pxl-test collision would definitively be easier.

Yeah... The grph screenn make sense. To bad theres no xlibc for the v200 :/

Multiple implementations of high-level languages which execute faster than the TI-Basic have been made on the TI-68k platform, years ago. GFA-Basic (known from another platform), NewProg, etc.

But if you use the graph buffer you still dont solve the problem of removing the last parts of the snake :/

yeah :/

It's a shame that NewProg didn't take off like Axe, but I guess it was inevitable with the much smaller amount of 68K coders at the time. Of course, there's always Vertel or FLIB, though, which are similar to xLIB on Z80 models.

As for GFA Basic I never checked it much, but some people used it back then if I remember. I don't know if it's available on ticalc.org, though, and the main site hasn't been updated in a while, so it would be better to download it now if you want to try it, in case one day the site goes down. http://www.tigen.org/gfabasic/

Yaaaaay more people are writing stuff for the 68k calcs! Keep it up!
