//Haupt-Problem: Wie kann ich Spieler vom Spiel ausschliessen, wenn sie alle Leben verlohren haben? (Kann man respawn unterbinden?)
//Aktuelle Notloesung: Spieler wird unsichtbar und kann keinen Schaden austeilen, aber: setradarinvisibility funktioniert scheinbar nicht
//Lösungsidee2: Spieler werden als passive Drohnen respawned, wenn sie keine Leben mehr haben (noch nicht implementiert)
