运行环境

Minecraft版本(1.12.2/1.16.5/1.18.2): 1.18.2 构建版本(从/version指令获取): https://github.com/Luohuayu/CatServer/commit/ecf29bc1c0415372734f9fd7de8d6baa19f149b9 相关模组/插件: 代码如下

一个简易 spigot Event 处理：


PlayerInteractAtEntityEvent e 从 EventHandler 接到事件
Entity entity = e.getRightClicked();
entity.teleport(loc);

描述这个BUG

当 entity 是末影龙，且世界不是 DIM1 end 时：

java.lang.ClassCastException: class net.minecraft.world.entity.boss.enderdragon.EnderDragon cannot be cast to class net.minecraft.world.entity.boss.EnderDragonPart (net.minecraft.world.entity.boss.enderdragon.EnderDragon and net.minecraft.world.entity.boss.EnderDragonPart are in module minecraft@1.18.2 of loader 'TRANSFORMER' @21ae657b)
