Hi. I might be new to this site, but I'm hardly new to BASIC. I've been teaching myself TI-BASIC for nearly 5 years now. I only just found this site maybe a month ago. Although the most significant bits of info I've learned from this site so far are mainly related to assembly, text sprites, and piecewise statements, (oh yeah, & finance variables), these techniques have made my programs much better than they were initially. I will admit that I'm extremely pleased that in these past almost five years i have managed to teach myself/discover for myself a large portion of what is on this site. (not that this site isn't useful, I visit it almost everyday!) I was also surprised when i saw the version of snake on this website. My version of snake was developed well before i found out about TI-developer, but the format of the two games is extremely similar, & both programs utilize the pixel test for obstacle detection. My version of snake is now at version 12.0 and it averages at about 10 or more fps. I do not have levels in my version, for I prefer the "continuous" method, but I do implement a high score table, pausing, and many other little features. Technically I do use SOME assembly coding, but only to get rid of the run indicator, to invert the screen during set-up, and to eliminate the done at the end of the program.
Anyway, I love this site, and I have learned a lot in the short time that I have been utilizing its pages.
Sorry, forgot to mention: I started out on a TI-73, but within the past four or five months I got a TI-84, which i am extremely pleased about. The TI-73 really is hard to program, and it lacks both speed and features. Not trying to disrespect the calculator; there are probably people out there who love the 73. I just happen to like the 84 more. A LOT more. Anyway, since I got the new calc, I have made binary converters, a few games, and an analogue/digital clock, amongst other things.
EDIT: I merged all three of your posts. Please don't double post — burr
