AS2 Sprite Shooting left and right... need help!

Hey

Im working on a platform game and need some help if possible.

I need to know how to make my sprite fire right when facing to the right and fire left when facing to the left.

I followed a shooting tutorial which was really good but not ideal for the style of game I want to make. Hence the sprite will only fire to the right.

Does anybody know of any tutorials that cover this?

Thanks!
