I am designing a space shooter, but I'm stuck with this blue backround.. I attempted to use the statement "COLOR BACKDROP 0" but it does not work... It worked when I was playing around in 3D Mode. But I can't seem to get it to work in 2D mode.. Any Ideas?

Hello Tone Eternal,

try this:

`This will turn on the background
backdrop on
`This will give you black bacground
color backdrop rgb(0,0,0)

or you could put a texture:
`This will turn on the background
backdrop on
'This will texture the backdrop
texture backdrop imgNumber
`Where imgNumber is the texture for the background

Cheers.

im not sure..but..instead of using backdrop..paste an image before..the rest...it will be..faster....and you wont be abligated to redraw ..the entire screen each "sync" cause with backdrop on..it erase your screen each sync..

What you can do Tone Eternal is that
You put a sprite to fill the whole screen.
Make the image of the sprite, the size of the whole screen.
That is if the screen resolution is going to be 640 x 480
make the image this size etc etc.

Anyway, the backdrop is the fasted way to have a 2D Background.

Cheers.

The point is that there are many ways to do what you want:
sky box/sphere
texture backdrop
sprite
paste image
copy bitmap

The only thing I would like to add is that if you are going to use one of these methods, don't forget to include 'BACKDROP OFF'.

By default, DBPro will clear the screen every frame, but if you are going to ensure that it is entirely redrawn each time this is wasted effort that will slow down your game.
