Well this the way how I did it.
Create a timer like SetTimer("Tutorial",20000,1);
Or use SetTimerEx if you want.
Create the Callback Tutorial

Код:

new Tut[MAX_PLAYERS];

forward Tutorial();
public Totorial()
{
	for(new i = 0; i < MAX_PLAYERS; i++)
	{
		if(Tut[i] == 1)
		{
			SendClientMessage(i, COLOR, "Text for the first part of the tutorial");
			Tut[i] = 2;
		}
		if(Tut[i] == 2)
		{
			SendClientMessage(i, COLOR, "Text for the second part of the tutorial");
			Tut[i] = 3;
		}
		if(Tut[i] == 3)
		{
			SendClientMessage(i, COLOR, "End of the tutorial.");
			Tut[i] = 4;
		}
	}
}

I hope you can create a command like /starttutorial. So the Tut[playerid] go to 1
Then the tutorial will start.
