To use those sprites, you have to separate them and save them as an individual image and load them each into DBP like so,
load image "bob.png",1
load image "jim.png",2
sprite 1,x,y,1
sprite 2,x,y,2
When you load the image be sure that they are in the same directory with you source file. You can add a directory to load with the image. Example,
load image "blah\bob.png",1
Your sprites represent the following.
sprite
1,x,y,1 - Your sprite number, be sure that this is specific and different from all of the others or you will get a runtime error.
sprite 1,
x,y,1 - The x or left or right position of your sprite. This is where you want your sprite to appear on the screen.
sprite 1,x,
y,1 - The y or up and down position of you sprite. This is where you want your sprite to appear on the screen.
sprite 1,x,y,
1 - This is what the sprite is. The image number of the image you loaded should be here if you want that image to be a sprite.
Now since you are using DBP a backdrop will come up (a big blue thing) so you can use the command,
Or if you want the backdrop (best) but a different color, use this command.
backdrop on
color backdrop rgb(red#,green#,blue#)
Use the DBP tutorials for a better explanation and welcome to the forums.
Cheers and good luck,
