TheRPGAdventurer Posted December 13, 2018 Share Posted December 13, 2018 I have a dragon whistle item, i want the whistle to use it for specific tasks such as circling the player coming to the player, following the player while flying etc. I have coded the flight AI now I need an Item, A dragon whistle to trigger them, so i tried putting commands with an ENUM. but when I use it on addInformation() the game crashes with a nullPointerException ItemDragonWhistle: https://pastebin.com/YQ2MMzEF EntityTameableDragon: https://pastebin.com/wBYHLk26 StatCollector: https://pastebin.com/Bud1QeZ8 Quote Link to comment Share on other sites More sharing options...
V0idWa1k3r Posted December 14, 2018 Share Posted December 14, 2018 Well obviously commands is null. Yes, an Enum can be null in java. Also you can't store the field in the Item like this. Items are singletons, meaning that when you change this field for your item it will be changed for all of them. You must use capabilities or NBT.
