So kann man dir leider kaum helfen, denn solange der Code nicht eingerückt ist und im Code-Tag steht, habe ich (vermutlich auch andere) keine lust mir diesen durchzulesen.
Auch ist es hilfreich welche Zeile den Fehler schmeißt.

Die Fehlerausgabe besagt aber, dass eine Variable auf nichts verweißt. Eine klassiche NullPointerException eben.

BlackHole · 29 Oktober 2017

Scheinbar handelt es sich um diese Zeile:

Code:

if (e.getItem().getType() == Material.EYE_OF_ENDER) {

PlayerInteractEvent.getItem() kann null zurückliefern, wenn der Spieler kein Item in der entsprechenden Hand hat.

Vielen Dank BlackHole,

Wüsstest du wie man die Fehlermeldung umgehen kann?
LG

BlackHole · 30 Oktober 2017

Am Besten natürlich dadurch, dass du dich mehr mit den Grundlagen von Java beschäftigst.
In diesem konkreten Fall z.B. dadurch, dass du prüfst, ob das Item null ist. Dazu kannst du das Item in einer Variable speichern oder den Code z.B. so abändern:

Code:

if (e.getItem() != null && e.getItem().getType() == Material.EYE_OF_ENDER) {

Versuche am Besten genau zu verstehen, was der Code dort macht.
