2 questions here. Is it possible to create bitmaps to a starfield and make them look as if they are off in the distance. Im guessing it involves layers to achieve this? Im using the tutorial star field as my layout for my first game(learning experience) and I wanted to achieve moons, and maybe colors in the background, and then have the stars pass through the image.

simulating a nice backdrop. A small example, or general answer will do me fine, I much rather figure it out myself, since the personal satisfaction is greater

Is it also possible to create sprites on the screen faster than the sprite 1,x,y,1
ect..?

I'm not sure which tutorial you are using but - you could create sprites and set there priority to a high number to have them drawn behind other sprites.

set sprite priority spritenum, priority

set sprite priority 1,50
=====================================================================
You can use paste sprite, if you don't need to retain the collision, Also have a look at clone sprite
=====================================================================
Also sprites are faster if you turn the backsave feature off

have a look at set sprite command
if you turn off the backsave you will be responsible for clearing the screen and resrawing it each loop if the sprites are going to be moving.
=====================================================================
You may also want to look at using textured plains as it may be easier to et the effect your looking for.
=====================================================================

Don't know if that's what you need, but I just wrote something similar for my space shooter last weekend:

A 3-layer-scrollable-starfield-background made out of 4 Tiles (64x64) for each layer which are placed randomly at the start and scroll down in an endless loop with different speed for each layer - looks nice

I can post the code later when I am back at home.

I used your set priority command and got the sprite on and everything was ok, but im still struggling to get the stars to go over the sprite.

here is the code I added.

The tutorial I used is the 2d starfield one under the DBpro tutorial section. if you need all the game code, just ask.

I'll take a look at the tut and what you have posted here. And be back in 2 licks of a stick!

And I retrieved my laptop form work, so I'm back in business with a compiler.
