I regret to inform you all that my hard drive was wiped from an accidental format, i was unable to recover my projects and will be starting them over from scratch, new topics will be made for each project and the old ones locked.
luckily this is not as bad as it sounds, i probably have Piworld PC on my other computer, and Pifreak still has the original BasiC++ source, so when i say starting over from scratch that is a bit of an exaggeration. However i may/may not start them over from scratch anyway for various reasons.

BasiC++ will be an interpreted programming language for the PC based directly off of Ti-Basic currently it has: ClrDraw Pxl-On Pxl-Off Pxl-Change Getkey(sort of) storing(sort of) right now i am working on the font system to be used with Text() current features i want to get implemented are: and Ans Else End For getkey Goto If Input Lbl not or Pause Prgm Prompt Pxl-Test RecallPic Repeat Return Stop Text While xor credits go to pifreak for the original BasiC++ source :{D info on why file loading wasn't working: i was declaring std::string Filename; globally, (this is a string to hold the name of the file that gets loaded into the system, its declared globally so everything can use the code, it isn't limited to one single function) next in the main function i stored the contents of the Filename into the string so that it can be opened in my run() function std::string Filename = argv[1]; (when you drag and drop a file onto the program the name of the file is stored in Argv[1]) This will not work. What happens here is that the string is re-declared locally, this means it can't be used outside of main, this is because putting std::string in front of Filename tells it that you are declaring filename as a string, which overides the previous declaration. in order to fix this you simply do Filename = argv[1]; as can be seen it is a very basic mistake, but it should definitely be payed attention to because it can cause a lot of trouble if one doesn't understand it thanks go to Chile from Efnet's #C++ for pointing this out to me, and pifreak for helping as well and stuff

a quick demo of what the creatures will be like in piworld, this version is unoptimized and so it runs a bit slow, has a glitch with the health display, and could be better, but its my first attempt at creatures, and i think its a pretty good start, i hope you guys like it

Ohai, i believe i would be the only person posting in here who is actually new xD

I am currently working on a pure ti-basic adventure game named piworld. as of now i have: 6 maps
1 item
2 npc's
1 warp tile
a good movement engine
collision detection
the game uses ASCII characters for the npc's and main character and the maps are called up using Iambian's asm lib PicArc, it runs on the graph screen. the game is still in its very early stages of development but once i have creatures to fight and a few other things i'll release it.
