Intro
Sometimes you want to add a custom flag to the players, so you can control something, for example if they did or not a quest and if they will be able to do it again or not.
Of course you don´t want to delete players and restart the shard etc.

Description

Go to \Scripts\Mobiles and open PlayerMobile.cs

Now, look for private int m_Profession;

just below it, place your flag/variable, as example:private bool m_test;

Now, to keep this organized, lets add just below this declaration

//test flag for quest of the tutorial
             [CommandProperty( AccessLevel.GameMaster )]
		public bool test
		{
			get{ return m_test; }
			set{ m_test = value; }
		}

Now we must search for switch ( version ). This step is very important, and forgeting this will cause some doom

             switch ( version )
		{
		 case 19:
		            {
			m_test = reader.ReadBool();
			goto case 18;
			}

		case 18:
			{
				m_SolenFriendship = (SolenFriendship)...

Now, look for

writer.Write( (int) 18 ); // version

and change 18 for the newer version, 19

And finally, add below this last line,

writer.Write( m_test );

Presto!

Conclusion

Adding custom flags can be a powerfull tool when designing a quest, and as this tutorial shows, its easy to implement, and can be easily accessed from other classes.
Also note, the method above can use others variables too, with few changes.
