I''m sure there''s a more efficient algorithm for this (isn''t there always
), but here''s a radar-screen type thing that I messed around with for a few hours. By the way, I love this forum Teej...thanks for all your time and effort!

Teej, this tutorial is awesome. I''ve been learning how to program for the last couple of years in school and now I finally get a chance to put some of that to GOOD USE!!!
It''s not much, but I have learned so much from this tutorial, I wanted to contribute something while it is still relevant.
So...for anyone who is interested in a scrolling starfield, here it is.

Hey, the anon person with the square sample program was me. I forgot to login. Now you know.

Sorry, something went wrong on the original post, and some bits got cut off. How do you post code into a listbox? And how do you copy that code into VC++ without it all being on one line?
Anyway, I didn''t check it all but in the part labeled:
// Draw the stars onto the display
and under the "for" loop it reads:
"if (p.x>0 && p.x0 && p.y //this bit sets different colours, depending on the distance (z)"<br><br>but it should read:<br><br>"if (p.x>0 && p.x<SCREEN_WIDTH && p.y>0 && p.y<SCREEN_HEIGHT){<br>//this bit sets different colours, depending on the distance (z)"<br><br>I don''t know what happened, but hey, I hope this works because I deleted my version!<br><br><br> </i>

ok, I guess if a line is too long it gets truncated or something, so I'll try one more time!
