Question about wrapping actors like in asteroids demo.

[ericdg]

The asteroids demo contains this code to keep the asteroids and ship in the view.

[code]int w = view.width/2 + width;
int h = view.height/2 + height;
if(x > w) x = -w;
if( y > h) y = -h;
if(x < -w) x = w;
if(y < -h) y = h; [code]

This works fine, but why does it make the actors stay on the 0 axis of the game.

If you have your view in another position other than at 0, the actors will still wrap around 0.

How can I change it to make it wrap around the view regardless of the position of the view?[/code]

Try this:

Code: Select all

if(x > view.x + w) x = view.x - w;
if( y > view.y + h) y = view.y - h;
if(x < view.x - w) x = view.x + w;
if(y < view.y - h) y = view.y + h;
