Minecraft 改装 "Cannot instantiate the type" creatring CreativeTab

Question

我昨天在编写 Minecraft Mod 时遇到了问题。

代码如下：

Main.java class

package com.enricobilla.tempercraft;

import com.enricobilla.tempercraft.creativeTab.MyCreativeTab;

@Mod(modid = Reference.MOD_ID, name = Reference.MOD_NAME, version = Reference.MOD_VERSION)
public class TemperCraft {
    public static final MyCreativeTab tabTemperCraft = new MyCreativeTab("tabTemperCraft");
     ... other code ...
}

和MyCreativeTab.javaclass

package com.enricobilla.tempercraft.creativeTab;

import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.item.Item;

public abstract class MyCreativeTab extends CreativeTabs {
    public MyCreativeTab(String label) {
        super(label);
        this.setBackgroundImageName("tab_tempercraft.png");
    }
}

所以，我的问题是 Eclipse 报告我 "Cannot instantiate the type MyCreativeTab" 我在 Main.java 中写了 new MyCreativeTab("tabTemperCraft) 的地方，我不知道为什么...

我已经在 Internet 上查看过，但任何人都有同样的问题。

有人可以帮帮我吗？谢谢！

这里的问题是 MyCreativeTab 是抽象类型，无法实例化。您需要删除 class 声明的 abstract 关键字或子class 它。

查看 Java Specification:

的这句话

A named class may be declared abstract (§8.1.1.1) and must be declared abstract if it is incompletely implemented; such a class cannot be instantiated, but can be extended by subclasses.
