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 的第 81 行：

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

它反映的数量：

this.currentTaskAmount = -2;

如果需要，总代码： 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;
import com.rs.utils.Utils;

我在谷歌上找不到任何可以理解的东西。如果有人可以帮助我，那就太好了。

Answer 1

您已在此处声明长度为 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，这是无效的。对该数组有效的唯一索引是0。

要么修改你的数组更长，要么修改你的索引计算，使其不会产生1。

Answer 2

试试这个：

this.currentTask = (lowTasks.length > 1) ? 
        low_tasks[Utils.random(low_tasks.length - 1)] : lowTasks[0];
