[SOURCE] Command Prompt Pacman in C

Programmed it in Windows mostly for Windows but I did get it to compile and run successfully on my Linux virtual machine after some small changes. I don't know the proper way to clear the Linux terminal though so the previous screens just get pushed up unless you add the clear command.

It's commented for the most part but I got lazy and stopped because I'm tired maybe I'll do the rest later. Post your comments/opinions on my methods of doing things or what you think of it in general.

The game layout can be changed my modifying the big tiles array and anyone can pretty much do that. Also, it shouldn't be too difficult for anyone with some C/C++ experience to add a scoring counter based on the number of stars eaten or a number of other small things to make it more competitive or like an actual game of Pacman.

I tried to compile and toupper isn't declared (line 145).

I just made that line a comment.

And I couldn't get it to run on a unix server...but like you said, you made it for windows. Also is it supposed to be like pacman, because all I can do is move around a cursor and eat your name..(lol)

 

1. Thanks for noticing that it wouldn't compile, I just forgot to include ctype.h.

2. It should run on linux no problem.. I tried it and it worked. Also, that's what it is, moving around and eating my name but you can change the layout easily in the code and should be able to add scoring or other stuff without too much trouble.

 

Hmmm, Now for a pascal version?
