How? And how do you make it so that it seems to have multiple "layers"?
I''ve seen it done, I have a few ideas for getting it done... but I''m not sure about anything.
Thanks

Scrolling starfields
Advertisement
If you assign a depth value to each star and divide the movement of that star by that depth value, it will provide a good simulation of stars with various depths scrolling across the screen.
In my own designs, each star has a screen position (x,y) and a depth value d.
When I want to scroll the screen by (Ux, Uy) units, each star gets this treatment:
x = x + Ux/d
y = y + Uy/d
If the (x,y) is now off the screen, I wrap the values so that the star appears on the other side.
