I have a small issue with an Asteroids clone I'm making. I move the asteroids across the screen with the following code:


Where ast_x[i] and ast_y[i] are the coordinates of the asteroids and ast_direction[i] is the movement angle (90 = right, 0 = up, etc). Also, if you can't tell, the asteroids are in arrays

So, my problem is that when the asteroid reaches a screen boundry, the asteroid just rides along the boundry, and doesn't follow it's defined rotational path. I have no code that does this. Is it because Dark GDK has issues calculating stuff outside of the screen boundries? Or is it something else I should debug myself?

No, the asteroid would just randomly shift into a different direction when it went offscreen. I managed to fix it up today though, turns our I needed to make the asteroid's coordinates into a float instead of int, as it was not as precise.
