C# function call to LUA variable. x = CsharpCalled(); print(x);

[jarjar1]

How can I get the return value in my lua script from calling my C# function.

Ex:

C#
        public static string GetFreeSlots(IntPtr pLuaState)
        {
           // List<string> FreeSlots = WoWScript.Execute("return GetContainerNumFreeSlots(0)");   //returns 15 as string (correct)
          //  List<string> FreeSlots = WoWScript.Execute("wfaInput(GetContainerNumFreeSlots(0))"); //(returns 15 also correct)
              WoWScript.Execute("wfaInput(GetContainerNumFreeSlots(0))"); //(returns 15 also correct)
            return "5";
        }

ingame I type: /script x = FreeSlots(); print(x);

and I always get nil.

I tried 2 ways of calling ExecuteBuffer and getting the return value. the cleanCore popping off stack vars way and the other way making a second input function. I think I missed something simple yet important.

Push return value. Return number of arguments pushed.

int __cdecl Script_GetSelectedItem( lua_State *L )
{
	if( !LuaListBox::IsValid( L, 1 ) )
		return luaL_error( L, "Usage: ListBox:GetSelectedItem();" );

	try
	{
		CListBox *pListBox = LuaListBox::Get( L, 1 );
		CListBoxEntry *pItem = pListBox->GetSelectedItem();
		LuaListBoxEntry::Push( L, pItem );
		return 1;
	}
	catch( ... ) { }
	return 0;
}

I have tested and made sure the stack has 2 values on it, the 2 return values from GetNumbBagSlots..(). Still no dice. I tried using lua_pushnum, lua_pushstring, lua_pushvalue. It does not matter, always returns nil. Also tried calling it from frame in endscene. Maybe there is a certain function you need to call or something like GetLocalizedText passing your variable?

But that makes it much more cumbersome to write bot scripts.

I little more explanation could of been helpful :P. Didn't understand what you meant until took a look at the script functions.

		CListBoxEntry *pItem = pListBox->GetSelectedItem();
		LuaListBoxEntry::Push( L, pItem );
		return 1;
	}
	catch( ... ) { }
	return 0;
}

                Memory.Manager.WoW.FreeMemory(Lua_GetLocalizedText_Space);
                return Result;
            }
            catch { return String.Empty; }
        }
