我正在尝试使用 Java 代码为我的世界制作一个 mod，并且看到我不是在询问与我的世界直接相关的事情，我想我会在这里问它。

在我的代码里面我有 renderItem.getItemModelMesher().register(copperIngot, 0, new ModelResourceLocation(RefStrings.MODID + ":" + ((CopperIngot) copperIngot).getName(), "inventory"));

在该行的末尾，它调用位于文件 CopperIngot 中的函数 getName()，并返回字符串“copperingot”。我想要做的是获取变量“copperIngot”的名称，并将其设置为在名为 name 的字符串中的小写。

我这样做的原因是我可以拥有 1 个文件锭、1 个文件块等（块和锭是在 Minecraft 基本代码中创建的变量类型 Block 和 Item）

现在我正在使用tinker_fairy发布的以下代码

`Field[] fields = MainRegistry.class.getDeclaredFields();
//gives no of fields
System.out.println(fields.length);         
for (Field field : fields) {
    //gives the names of the fields
    System.out.println(field.getName());   
}`

这给了我这样的控制台读数：

等等.....（我在那个文件中有 113 个变量 atm）

这不是我想要的，我希望它在运行 getName 函数时读取变量名，然后将该变量名写入字符串名称。现在有了代码，我给了我所有的变量，我不知道如何隔离我需要找到的确切变量。

提前致谢。

如果我正确理解了您的问题，而不是硬编码字符串，您想以小写形式返回类的名称。如何使用CopperIngot.javagetClass().getName().toLowerCase()的getName()方法。

此外，您可以很好地使用反射来获取变量名称并设置新值。

Class aClass = MyObject.class;
Field field = aClass.getField("field");
MyObject objectInstance = new MyObject();
field.set(objetInstance, value);

希望这可以帮助

您只想将其写入变量吗？

Field[] fields = MainRegistry.class.getDeclaredFields();
//gives no of fields
System.out.println(fields.length);         
for (Field field : fields) {
    //gives the names of the fields
    String name = field.getName().toLowerCase();
    if ( name.indexOf( "copper" ) > -1 ) { 
        System.out.println("you found copper: " + name);
    }   
}
