我们今天尝试为模组添加属于自己的配置文件(.cfg文件)

通过编写配置文件，可以让玩家对我们模组中的一些数据进行自行修改(生物生成概率、建筑物生成概率等)，对于整合包的作者们是一件美事啊~

1.新建ModConfig.java文件:

在文件中编写：

package com.Joy187.newmod.init;

import com.Joy187.newmod.utils.Reference;
import net.minecraftforge.common.config.Config;
import net.minecraftforge.common.config.ConfigManager;
import net.minecraftforge.fml.client.event.ConfigChangedEvent;
import net.minecraftforge.fml.common.Mod;
import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;

@Config(modid = Reference.Mod_ID, category = "")
public class ModConfig {
    @Mod.EventBusSubscriber(modid = Reference.Mod_ID)
    private static class EventHandler {

        private EventHandler() {
        }

        @SubscribeEvent
        public static void onConfigChanged(final ConfigChangedEvent.OnConfigChangedEvent event) {
            if (event.getModID().equals(Reference.Mod_ID)) {
                ConfigManager.sync(Reference.Mod_ID, Config.Type.INSTANCE);
            }
        }
    }

    @Config.LangKey("configgui.rejoymod.category.Menu0.GeneralConf")
    @Config.Comment("rejoymod general config.")
    public static final GeneralConf GeneralConf = new GeneralConf();

    public static class GeneralConf {
//        @Config.LangKey("rejoymod.conf.general.welcome")
//        @Config.Comment("The text shown when a player logs in. Can be a key or a string.")
//        public String WELCOME_MSG = "rejoymod.msg.welcome";
    }

    @Config.LangKey("configgui.rejoymod.category.Menu0.DebugConf")
    @Config.Comment("Config for developers")
    public static final DebugConf DEBUG_CONF = new DebugConf();

    public static class DebugConf {

    }

    @Config.LangKey("configgui.rejoymod.category.Menu0.SpawnConf")
    @Config.Comment("Spawning")
    public static final SpawnConf SPAWN_CONF = new SpawnConf();

    public static class SpawnConf {
        @Config.LangKey("conf.spawn.enabled")
        @Config.Comment("Spawn mod creatures")
        @Config.RequiresMcRestart
        // 决定模组中的生物能否在主世界自动生成
        public boolean SPAWN = true;

        //设定每个生物的生成概率
        @Config.LangKey("entity.wp.name")
        @Config.Comment("Spawn White Pig")
        @Config.RequiresMcRestart
        public int SPAWN_White_Pig = 5;

        @Config.LangKey("entity.bp.name")
        @Config.Comment("Spawn Black Pig")
        @Config.RequiresMcRestart
        public int SPAWN_Black_Pig = 10;

        //设定每个建筑物的生成概率
        @Config.LangKey("structures.xchamberx")
        @Config.Comment("Spawn xchamberx")
        @Config.RequiresMcRestart
        public int SPAWN_DCHURCH = 10;
        @Config.LangKey("structures.factory1")
        @Config.Comment("Spawn factory1")
        @Config.RequiresMcRestart
        public int SPAWN_FACTORY1 = 10;
        @Config.LangKey("structures.factory2")
        @Config.Comment("Spawn factory2")
        @Config.RequiresMcRestart
        public int SPAWN_FACTORY2 = 10;
        @Config.LangKey("structures.tank2")
        @Config.Comment("Spawn tank2")
        @Config.RequiresMcRestart
        public int SPAWN_TANK2 = 10;
    }
}

2.当我们设置好相关数值后，可以在相应的位置调用这些参数：

修改前可以参照一下：Minecraft 1.12.2模组开发(十六) 生物生成机制

调用参数修改生物生成概率：

    private static void addNormalSpawn(Map<Type, Set<Biome>> biomeMap) {
            //使用Config中的参数修改生物生成概率
            addC(EntityBP.class,ModConfig.SPAWN_CONF.SPAWN_Black_Pig, 1, 3, biome);
            addC(EntityWp.class,ModConfig.SPAWN_CONF.SPAWN_Black_Pig, 1, 1, biome);
        }

    }

3.同理，我们调用参数修改建筑物生成概率

if(next1==1) {
//将数值换成诸如ModConfig.SPAWN_CONF.SPAWN_DCHURCH的参数
                    generateStructureDCH(new ModWorldGenStructure("dchurch2"), world, random, chunkX, chunkZ, ModConfig.SPAWN_CONF.SPAWN_DCHURCH, ModBlocks.WASTELAND_BLOCK, BiomeOne.class);
                }
                else if(next1==2){
                    generateStructureFac1(new ModWorldGenStructure("factory1"), world, random, chunkX, chunkZ, ModConfig.SPAWN_CONF.SPAWN_FACTORY1, ModBlocks.WASTELAND_ROCK_BLOCK, BiomeOne.class);
                }
                else if(next1==3){
                    generateStructureFac2(new ModWorldGenStructure("factory2e"), world, random, chunkX, chunkZ, ModConfig.SPAWN_CONF.SPAWN_FACTORY2, ModBlocks.WASTELAND_ROCK_BLOCK, BiomeOne.class);
                }
                else
                    generateStructureTank2(new ModWorldGenStructure("tank2"), world, random, chunkX, chunkZ, ModConfig.SPAWN_CONF.SPAWN_TANK2, ModBlocks.WASTELAND_BLOCK, BiomeOne.class);

4.启动游戏调试，我们可以在run\config文件夹中找到刚刚书写的配置文件：

5.通过对参数的修改我们可以不断优化模组的用户体验效果

当我们减少黑猪的生成概率，游戏中的生成数量也相应减少了：
