The use of global variables
 
Is there a way to use the same variable in the host-mission and submission without using a .txt-file(for save variables)?

For example:
In host mission script I have count of planes
Code:
int countPlanes = 5;
In submission script I need to change this:
Code:
int countPlanes -= 1;
It is necessary to divide the script menu and script statistics, but they used to share data.

Now I now about this variant - http://www.sukhoi.ru/forum/showthrea...=1#post1766444

There are other alternatives a more simple than this? Maybe new class on dll help on it?

Yes a Singleton Pattern in a DLL.
http://en.wikipedia.org/wiki/Singleton_pattern

Example Singleton (threadsafe)
Code:
  public sealed class Singleton
    {
        public int planeCount { get; set; }
       
        private static readonly Lazy<Singleton> lazy = new Lazy<Singleton>(() => new Singleton());

        public static Singleton GetInstance { get { return lazy.Value; } }

        private Singleton()
        {
            // Initialisations
        }
    }
in Mis-C# you use for example

Code:
//$reference parts/core/MyDll.dll
using System;
using System.Collections.Generic;
using maddox.game;
using maddox.game.world;
using MyNameSpace;

public class Mission : AMission
{
 
    Singleton s=Singleton.GetInstance;  // get access to the singleton or create it if not exist.


 public override void OnPlaceEnter(Player player, AiActor actor, int placeIndex)
    {
        base.OnPlaceEnter(player, actor, placeIndex);

        s.planeCount += 1; // example
    }
}
use Singleton s=Singleton.GetInstance; in every Scriptfile you need acces to the singleton. There is always only one Singleton present.

        } // null
    }
}
stat.redScore, stat.blueScore - no error
other stat. have error
Second stat. element in smpSendMSG.MessageToAll - no error.
I have error on VS, but script work fine in game.

No problem by me, do you use a static class with name stat?
if you rename "stat" (singleton) the problem also exist?
