Rotating a sprite is done by dbRotateSprite(). Problem is that it will rotate the sprite around the upper left corner. For a shooter game you want it to turn aroud a predefined pivot point. Setting a pivotpoint for a sprite in GDK this is done by dbOffestSprite() command. Use dbMouseX() and dbMouseY() to get the mousepossition.
Use some gonimetric calculations to do the aiming.
