You aren't handling returns in those hooked callbacks. This will output warnings if used in includes.

pawn Код:

public OnObjectMoved(objectid) {
    #if defined mylib_OnObjectMoved
        mylib_OnObjectMoved(objectid);
    #endif
}

Should be:

pawn Код:

public OnObjectMoved(objectid) 
{
    #if defined mylib_OnObjectMoved
        return mylib_OnObjectMoved(objectid);
    #else
        return 1;
    #endif
}
