没有类型变量的实例存在,因此BlockBase确认BlockOre

我关注如何创建Minecraft mod的this tutorial。我得到以下错误,但我没有看到任何问题。我不知道这个错误意味着什么,更重要的是我不知道我在做什么,因此在教程之后。

我正在使用Forge 1.11和IntelliJ IDEA 2016.3.2 IDE以及Java 1.8.0_112 SDK。 根据一些阅读,我认为它与数据类型不匹配有关,但它可能只是我的IDE挑剔或它是Java 1.8 SDK的东西。我真的迷路了,所以我想会伸手去看看是否有人愿意提供指导。

错误:

  无法应用

ModBlocks中的寄存器(T)   (net.maramor.tutorial.block.BlockBase)

     

原因:没有类型变量的实例存在以便BlockBase   符合BlockOre推理变量T具有不兼容的边界:   下界:BlockBase上限:Block,BlockOre

[BlockBase.java]

package net.maramor.tutorial.block;

import net.minecraft.block.Block;
import net.minecraft.block.material.Material;
import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.item.ItemBlock;
import net.maramor.tutorial.TutorialMod;

/**

public class BlockBase extends Block
{
    protected String name;

    public BlockBase(Material material, String name)
    {
        super(material);

        this.name = name;

        setUnlocalizedName(name);
        setRegistryName(name);
    }

    public void registerItemModel(ItemBlock itemBlock)
    {
        TutorialMod.proxy.registerItemRenderer(itemBlock,0, name);
    }

    @Override
    public BlockBase setCreativeTab(CreativeTabs tab)
    {
        super.setCreativeTab(tab);
        return this;
    }
}

[BlockOre.java]

package net.maramor.tutorial.block;

import net.minecraft.block.material.Material;
import net.minecraft.creativetab.CreativeTabs;

/**

 */
public class BlockOre extends BlockBase
{
    public BlockOre(String name)
    {
        super(Material.ROCK, name);

        setHardness(3f);
        setResistance(5f);
    }

    @Override
    public BlockBase setCreativeTab(CreativeTabs tab)
    {
        super.setCreativeTab(tab);
        return this;
    }
}

package net.maramor.tutorial.block;

import net.minecraft.block.Block;
import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.item.ItemBlock;
import net.minecraftforge.fml.common.registry.GameRegistry;

/**

public class ModBlocks
{
    public static BlockOre oreCopper;

    public static void init()
    {
        oreCopper = register(new BlockOre("ore_copper").setCreativeTab(CreativeTabs.MATERIALS));
    }

    private static <T extends Block> T register(T block, ItemBlock itemBlock)
    {
        GameRegistry.register(block);
        GameRegistry.register(itemBlock);

        if (block instanceof BlockBase)
        {
            ((BlockBase)block).registerItemModel(itemBlock);
        }

        return block;
    }

    private static <T extends Block> T register(T block)
    {
        ItemBlock itemBlock = new ItemBlock(block);
        itemBlock.setRegistryName(block.getRegistryName());
        return register(block, itemBlock);
    }
}

是的,这是MC 1.10及更高版本的一种方法。基本上你必须在加载游戏时注册块,项目和纹理,以便在你创建/加载世界时可以使用它们。

T寄存器(T块)是ModBlocks类中的通用函数。

oreCopper = register(new BlockOre(&#34; ore_copper&#34;)。setCreativeTab(CreativeTabs.MATERIALS));

将类型为BlockBase的实例传递给函数寄存器,以便预期的返回类型也是BlockBase。
