java.lang.ArrayIndexOutOfBoundsException : 1

Question

这里出了什么问题？

错误:

java.lang.ArrayIndexOutOfBoundsException: 1
at com.rs.game.player.content.SlayerTask.getNewTask(SlayerTask.java:81)

SlayerTask.java第81行:

this.currentTaskAmount = amount[Utils.random(low_tasks.length - 1)];

它反射(reflect)的金额:

this.currentTaskAmount = -2;

总代码(如果需要): 包 com.rs.game.player.content;

import java.io.Serializable;

import com.rs.cache.loaders.NPCDefinitions;
import com.rs.game.player.Player;
import com.rs.game.player.Skills;

我在谷歌上找不到任何可以理解的内容。如果有人能帮助我那就太好了。

您已在此处声明了长度为 1 的数组:

private transient static int[] amount = { 1};

但是，根据您的异常消息，您传入的索引为 1，该索引无效。该数组唯一有效的索引是 0。

要么将数组修改得更长，要么修改索引计算，使其不会产生 1。
