I have a tilemap of non-animated sprites, and there will be an animated sprite over them which is the size of the game screen. However, no matter where I put the dbPlaySprite command the animated sprite ends up getting drawn behind the tilemap. How can I manipulate the Z-order of the sprites? I've tried dbDrawToFront, but that wouldn't work anyway, would it?

From the documentation:

+ Code Snippet

dbSetSpritePriority 
This command will set the relative priority of the specified sprite.
All sprites start with a value of zero giving them equal chance of being drawn last.
By setting a single sprite a value of one will cause that sprite to be drawn last.
You can specify a unique priority value for each sprite creating an order of drawing for every sprite in your program. 

Syntax 
void dbSetSpritePriority ( int iSprite, int iPriority )

I usually create function to control sprites priority just like that:

+ Code Snippet

void SpritesPriority()
{
   dbSetSpritePriority(1,1);    // Sprite: 1, Priority: 1
   dbSetSpritePriority(2,2);    // Sprite: 2, Priority: 2
   dbSetSpritePriority(3,3);    // Sprite: 3, Priority: 3
   dbSetSpritePriority(4,4);    // Sprite: 4, Priority: 4
   dbSetSpritePriority(5,5);    // Sprite: 5, Priority: 5
   (...)
}

In that case sprite with id = 1, will be on "bottom" of screen, then on top of it will be sprite 2 and so on....
Just insert that somewhere in you game/program main loop.

Yes, setting the priority works perfectly, thank you.
