    p.sendMessage("§6Tu vas être télépoté au spawn , ne bouge pas !");
    Bukkit.dispatchCommand(p, "spawn");
  }

Help me please

 

Uhmm... what?

Your problem is probably here:

Code:java

Player p = (Player)e.getEntity();
Player d = (Player)e.getDamager();

You need to CHECK they are Player's before casting them. You're casting but you're doing it in the wrong place.
