anyway i have a new question (but please answer the last one to!)

In the tileset: Heaven, the you have a bird with can fire fire bals (at least, the sprites are there)

I try to do it but i dont understand it. How must you place the sprite, at wich speed and what must you use to get the bird fire 1 fire bal, wait a little time and fire another, the fire ball have to fly 10 tiles far.
