@Dark Byte Ideally you could, but you would need to use c++ interface to work with .DLL in Lua.
C++ Code ~= work with Lua.

Thanks. Now I need to know how to create global variables using the C API. I have this
Code:
1
2
3
4
5
6
7
void LUA_setglobalval(lua_State* L, const char* var, int val)
{
     lua_getglobal(L, var);
     if ( !lua_isnumber(L, -1) )
          lua_setfield(L, LUA_GLOBALSINDEX, var);
     lua_pushnumber(L, val);
}

Would that work properly?

addhook("minute","addcredits")
function addcredits()
     for i=1,32 do
          if (player(i,"exists")) and (hacker[i]==1) then
               credits[i]=credits[i]+15
          end
     end
end
how do i make instead "if player exists" to "if player lvl[id] 5 or bigger ?

-------------------------------------------------------

can anybody make something like
admins = {15476,1,and so on}
and only admins can acess

Code:
1
2
3
4
5
6
7
8
9

if button==6 then--WTF? Admin Commands = buy credits?
menu(id,"Admin Panel,5 Credits|1000$,10 Credits|2000$,15 Credits|2750$,20 Credits|3500$,50 Credits|9000$,100 Credits|15000$,200 Credits|1 Mega Point")
end

if button==7 then--WTF? Music = buy credits?
menu(id,"Songs,Under Development (picking songs),10 Credits|2000$,15 Credits|2750$,20 Credits|3500$,50 Credits|9000$,100 Credits|15000$,200 Credits|1 Mega Point")
end
end

end


dont mind this credit thingy cause so far me and my clan leader are picking what should be in. I just need that only if player USGN = that and that, then he can enter menu with that button, else it will say "sorry you are not Admin". Thank you for your help.

Add the script above (I modified yours) and then if you want to check if someone has a mercendes, use:
if(hasmerc[id]==1) then
--code

@Jony and Jake-Rus,
Those errors are completely normal.
The problem lies in the "primitive" bots (they use lua).
When you use cs2d cmd luareset they generate an error:
the one you described.(It cancels out the bot's lua scripts) Let's see if DC decides to make cs2d cmd luareset not affect the bots scripts.
