java - 从抽象类中获取变量

Question

基本上我想获取从“World.class”播放的 map 的名称，在我的主 mod 类的字符串中...

    public abstract class World implements IBlockAccess{
    protected WorldInfo worldInfo;
    //=====OtherStuff=====
    public World(ISaveHandler par1ISaveHandler, String par2Str, WorldSettings par3WorldSettings, WorldProvider par4WorldProvider, Profiler par5Profiler, ILogAgent par6ILogAgent)
        {
        this.worldInfo.setWorldName(par2Str);
        }
    //=====OtherStuff=====
}

我在与此相同的包中创建了一个类

public class World_Spy extends World{

    public World_Spy(ISaveHandler par1iSaveHandler, String par2Str,
            WorldProvider par3WorldProvider, WorldSettings par4WorldSettings,
            Profiler par5Profiler, ILogAgent par6iLogAgent) {
        super(par1iSaveHandler, par2Str, par3WorldProvider, par4WorldSettings,
                par5Profiler, par6iLogAgent);
    }

    @Override
    protected IChunkProvider createChunkProvider() {
        return null;
    }

    @Override
    public Entity getEntityByID(int i) {
        return null;
    }


    String TheName = "";
    public void gotIt(){
        TheName = this.worldInfo.getWorldName();
        System.out.println(TheName);
    }

}

我从我的主类中调用它:

World_Spy WName = new World_Spy(null, null, null, null, null, null);

但是启动时崩溃了... 有什么想法吗？

World 不是静态类...您需要一个 World 兼容对象的实例来获取名称。获取 World 实例和名称的一种方法:

World world = Minecraft.getMinecraft().isIntegratedServerRunning() ? mc.getIntegratedServer().worldServerForDimension(Minecraft.getMinecraft().thePlayer.dimension) : Minecraft.getMinecraft().theWorld;
String worldName = world.getWorldInfo().getWorldName();

此代码应该在客户端运行。
