我的维数调制破碎机

Question

我已经在我的模块中创建了一个维度，当右键单击该项时，应该将您传送到所述维度，但当我右键单击该项时，我会崩溃。代码中没有错误，我也不知道是什么造成了日志中的问题。我使用内置的平面块提供程序生成维度。任何你需要的文件我都能提供。很抱歉有什么奇怪的格式，我不太习惯。

Answer 1

com.killer.sheerpig.ItemSheerTP.onItemRightClick(ItemSheerTP.java:42) java.lang.ClassCastException:不能将net.minecraft.client.multiplayer.WorldClient转换为net.minecraft.world.WorldServer

再次阅读错误消息，您将看到问题在于您的最后一个代码片段，即在onItemRightClick的else块中的第一个命令。

问题是，通过对其进行转换，您可以在该行中解释"world是WorldServer类型“。但它显然不是--而是WorldClient型的。

您可能更喜欢类似于这的内容，特别是这个片段：

Minecraft mc = Minecraft.getMinecraft();
if (mc.getIntegratedServer())
{
    worldServer = mc.getIntegratedServer().worldServerForDimension(mc.thePlayer.dimension);
}
else if (MinecraftServer.getServer())
{
    worldServer = MinecraftServer.getServer().worldServerForDimension(mc.thePlayer.dimension);
}

也许这有帮助，也许没有帮助，但关键是你的world并不是在所有情况下都是WorldServer。

造成这种情况的原因可能是您混淆了服务器端和客户端。如本论坛所述似乎Entity.worldobj是服务器端的WorldServer。
