Im making a vertical shooter. I can get the enemies to move around and come and ram their ship at me, but I wrote some code for them to shoot bullets at me but nothing happens here is my code, I will highlight the bullet code in bold

My bullet code is located in the implementation file. the functions are called updateenemybulle, updatenememybullets, and fireatplayer(I call this in updateenemyplanes()). Skip the loadsprites code. Im just loading them in

This is the point at which you need to begin debugging.

Set breakpoints in the code, at key places in the code - including the places that SHOULD be calling the shooting functions.

Use the debugger to step through the code, line by line (look up how to "step into" and "step past" lines of code in your particular IDE). Pay attention to the key variables involved in this behavior.

When you isolate the problem to a certain section of code, you'll probably be able to figure it out. If you still need help, post the section of code and explain exactly what behavior you expect to see (in terms of variables and functions), and what behavior you actually are seeing. But until you can be more specific, you can't expect us to read all of your code and figure it out - nor should you want us to. THIS is what computer programming is all about, and you'll never learn it if you don't try it for yourself.
