Problem bei einem Skyblock Plugin

ausgebildet · 8 Februar 2018

Hey , ich brauche Hilfe bei meinem SkyBlock Plugin. Sobald ich meine Insel erstellen will folgt einer NullPointerException in der Island.class (Zeile 51).

Fehler :

Code:

[03:44:45 WARN]: [SkyBlock] Task #143 for SkyBlock v2.9 generated an exception

Um eine Insel zu erstellen rufe ich folgende Methode auf

"plugin.getIslandManagerClass().createIsland(sender);"

Die InselManagerClass sehr ihr hier.

Deine Plugin Variable aus Zeile 20 in Island.class ist null. Entweder du erstellst in deiner Hauptklasse eine statische Variable, welcher du deine Plugininstanz beim Starten zuweist, und greifst dann aus deiner Island.class direkt auf sie zu oder du übergibst im Konstruktor deine Plugininstanz (Wie du es in der InselManager Klasse auch machst...).

Gut danke. Hat geklappt. Oft sind es die kleinen Dinge die wir übersehen.
