I want that my script start when game begins. The script has a state, I want the player to be in it immediately.
But I don't know how to do this! What this script should extend? ot must it be hidden? or what?

Also I want to add a spell when player loads/starts the game, same problem, I know not how.

I would create a quest that starts with game. Then you can attach any scripts you want and put the player in an Alias.

Attaching this to the quest script will also add a spell to the player if they don't already have the spell.

SPELL Property MySpell AutoEvent onInit()if !Game.GetPlayer().HasSpell(MySpell)Game.GetPlayer().AddSpell(MySpell)endifEndEvent

Once you have a script that is run when a new game is started, you can add a spell with the following lines:

Spell Property NameOfYourSpell Auto

Game.GetPlayer().AddSpell(NameOfYourSpell)

Just remember to set the correct spell in the script's Properties window.

EDIT: I was too slow.

Thanks mates
