[Mikael.]

Ingenting vil funke uten om /pvp som gir deg hjelpemenyen.

Er ikke sikker hva som er feil.

Testen

if (args[0].equalsIgnoreCase("setlobby")){ 

feiler fordi args-arrayet ikke er så langt (dvs det er tomt). Du sjekker om args.length == 0 litt lengre oppe, men har ingen else rundt koden som baserer seg på at args[0] finnes.

 

(Du bør også sjekke om args[0] er null eller ha teksten først og variabelen sist i equals testene)
