我目的是搜索当前世界的某个玩家的坐标，在单人世界可以执行，在服务器世界上执行就会崩溃且跳出游戏，请问各位有何解决方法？

版本是：forge-1.7.10-10.13.2.1236

以下是部分代码：
  1. <p>public class GuiTeleportTicket extends GuiContainer
  2. {        ....略
  3.         protected void actionPerformed(GuiButton guibutton)
  4.          {        
  5.                 //每当执行这一行都会在Server崩溃
  6.    EntityPlayer goToPlayer=MinecraftServer.getServer()
  7.    .getEntityWorld().getPlayerEntityByName(this.text.getText().toString());
  8.    
  9.    Minecraft.getMinecraft().thePlayer.sendChatMessage(this.text.getText().toString()+" coordinate at:"+goToPlayer.posX+","+goToPlayer.posY+","+goToPlayer.posZ);
  10.         }
  11.         
  12.         ....略
  13. }
  14. </p>
复制代码


以下是崩溃的资讯：

看错误写的是数组的索引超过了界限，0，会不会是因为没有获取到对应的玩家实体呢？我不清楚，getPlayerEntityByName返回的是数组还是单个玩家实体。可能服务器里面没有这个名字的玩家。貌似调试的时候，玩家名都是player后面跟一串随机数字的，如果是这样，下一句输出消息之前，加一个非空判断，应该就不会报错了。如果不是这个原因的话。。。我也不清楚了，刚接触mod不久，也不是很熟悉，嘿嘿（话说其他地方我也没看到数组的影子....）

ok我會試試看的謝謝你，我看了其他文章是說不能直接取得server世界的資料，不過具體解決方法還不知道，如果解決了會再把方法貼上！
