I was writing code for some game and it was working fine as it should be , then I modified a small thing in the script file , and when I run the engine after that I got a message:

nonexistent / empty function in (xy)

I dont know why did I resieve an error message about this function , It wasnt the one which I modified , I modified a totally different that has nothing to do with that errored function , and there are no syntax faults in it or in any part of the script , I erased that function but it gave me the same error , please could someone tell me how to get rid of this nightmare???

and thanks in advance

perhaps you did forget a brake "}" ???

I swear I checked it like a hundred times there are no syntax mistakes at all

confusing... can you post the code??? that would help much more^^

the function aiming() is the one which is getting the error message

when I press space the gun fires a bullets and when it collides with a bat the bat is removed , and the but is not moving so dont fell strange about that
the error began when I modified the remove_bullets() function , I just added an if instruction for event_entity and event_block , thats where every thing was screwed up

the rest of the code is nothing more than definisions like vars and panles , and by the way , the gun is supposed to play an animation when it fires a bullet , but it doesent , dont know why


there are some meanless commands like controling the transparency of the gun

action move_bullets is missing a bracket at the end. Thats why function aiming is popping up as an error, the compiler is expecting a bracket but didnt find one and so falls over at that function.

Try changing the order of functions so another function is called after action (before you set the close bracket in) and see what the compiler says.

yes and move_bullets() is ,missing a wait(1); after c_move!

that did it , I think I just deleted something by mistake
