My code compiles perfectly when i don't use the "NEBULA.h" code...

I know this is simple but each time i post about Allegro on the Beginners forum there are no replys. So I'm hoping you can help out.
~ Thanks...

Usually a question includes a question mark...
Either way... take a look at the error. It says you have redefined void moveCircle(). Or, in other words, the function has been declared more than once. To solve this, give each function a separate name.

Also, your include guards are wrong. This is not the cause of your error, but you should write it correctly either way. Include guards are done like this (make sure to replace the INCLUDEGUARDNAME):

1
2
3
4
5
6
 
#ifndef INCLUDEGUARDNAME
#define INCLUDEGUARDNAME

... {your code here} ...

#endif
