Simple Boids Problem
May 09, 2010 07:47 PM
I have tried to implement a boids algorithm into my current game, but am having some issues. When the boids code is removed the 100 objects draw to the screen fine, just static, but when I add the boids code they dont appear at all. Code is here: http://pastebin.com/MaVvdPyk

Have you checked what the positions are after moving the boids? Could it simply be that they're moving really far away from the camera really quickly?
Also there's no timing involved in your code; usually application of velocity looks something like:
position += velocity * deltaTime;

First question of self-sufficiency:
"Have you stepped through your code to see if your positions stay within drawable bounds?"
If you haven't stepped through your code during execution, then neither should we.

... by 22 seconds, Hodgman. 22 seconds.
Regardless, we are both asking the same thing.

I followed your advice and stepped through my code and found the problem. The algorithm is wrong slightly and doesn't do what it should but the result at the moment is actually better for my purposes. Thanks for the help.

Aaaaahh... yet another victory of self-sufficiency.
