hey. how do i make my sprite shoot bullets? and how do i make the enimy get hit and loose lives and vise versa ignore screenshot

That will involve some fairly beefy code When I get access to my 3DS I'll help Unless someone beats me to it

If you have a spritesheet, with bullets and whatnot then you should upload it

example of firing missile. key QKYEA3H3 (enemy and collision not included)

well I have something I could give you but it is like very confusing if you are not already a decent programmer so it would be very hard for you to use
