Sorry to bother you guys again.....
but my Edge function (the one that fills the edgebuffer)
doesnt work, and I cant see whats wrong with it.
Please help, thanks in advance
here it is:
The problem is that ppl do not like debugging someone else''s code.
I always suggest this tip because I learned it in a simple QBASIC class in college around 2 years back.
1) Define what you are going to do..
2) Write down the logic for what you want the computer to do
YOURLOGICLOOP:
3) Break that down even further
4) Analyze logic by playing computer and writing down variables and the outcome on a piece of paper.
5 a) if error then grab an eraser and go back to step 2
5 b) if works jump to YOURLOGICLOOP until all variable limits are valid for the function you are writing
5 c) if error go to step 2 until eraser is gone or brain melts through ears
6) Start translating logic into actual code
7) Have a soda and relax

Maybe I''m missing something, but what exactly is this functions supposed to do? Maybe THEN I can help...
