如何检测玩家的死亡以及导致其死亡的原因 - Fabric MC 1.20.4

Question

我尝试过使用mixin，但它似乎根本无法运行，以下是我的代码，

import net.minecraft.entity.damage.DamageSource;
import net.minecraft.entity.player.PlayerEntity;
import net.spamta.pvpoverhaul.PvPOverhaul;
import org.spongepowered.asm.mixin.Mixin;
import org.spongepowered.asm.mixin.injection.At;
import org.spongepowered.asm.mixin.injection.Inject;
import org.spongepowered.asm.mixin.injection.callback.CallbackInfo;

import net.fabricmc.fabric.api.event.lifecycle.v1.ServerTickEvents;
import net.minecraft.server.MinecraftServer;
import net.minecraft.server.network.ServerPlayerEntity;
import net.minecraft.text.Text;

@Mixin(PlayerEntity.class)
public class GearKeeper {
    
    @Inject(method="onDeath", at=@At("TAIL"))
    private void died(DamageSource damageSource, CallbackInfo info){
        PvPOverhaul.LOGGER.info(damageSource.getName().toString());

        PlayerEntity player = (PlayerEntity) (Object) this;
        sendDeathMessageToAllPlayers(player);
    }

    private void sendDeathMessageToAllPlayers(PlayerEntity player) {
        MinecraftServer server = player.getServer();
        if (server != null) {
            server.getPlayerManager().getPlayerList().forEach(serverPlayer -> {
                serverPlayer.sendMessage(Text.literal(player.getName().toString() + " has perished!"), false);
            });
        }
    }

}

尝试检测玩家是否被杀，并期望它说“Piglin Brute”或当时杀死我的任何内容，但它最终没有记录任何内容。

import net.minecraft.entity.damage.DamageSource;
import net.minecraft.entity.player.PlayerEntity;
import net.spamta.pvpoverhaul.PvPOverhaul;
import org.spongepowered.asm.mixin.Mixin;
import org.spongepowered.asm.mixin.injection.At;
import org.spongepowered.asm.mixin.injection.Inject;
import org.spongepowered.asm.mixin.injection.callback.CallbackInfo;

import net.fabricmc.fabric.api.event.lifecycle.v1.ServerTickEvents;
import net.minecraft.server.MinecraftServer;
import net.minecraft.server.network.ServerPlayerEntity;
import net.minecraft.text.Text;

@Mixin(PlayerEntity.class)
public class GearKeeper {

    @Inject(method="onDeath", at=@At("TAIL"))
    private void died(DamageSource damageSource, CallbackInfo info){
        PvPOverhaul.LOGGER.info(damageSource.getName().toString());

        PlayerEntity player = (PlayerEntity) (Object) this;
        sendDeathMessageToAllPlayers(player);
    }

    private void sendDeathMessageToAllPlayers(PlayerEntity player) {
        MinecraftServer server = player.getServer();
        if (server != null) {
            server.getPlayerManager().getPlayerList().forEach(serverPlayer -> {
            
serverPlayer.sendMessage(Text.literal(player.getName().toString() + " has 
perished!"), false);
            });
        }
    }

}

您还应该在资源文件夹中创建一个名为 pvpoverhaul.mixins.json 的 mixin 配置文件

{
 "required": 1,
 "package": "net.spamta.pvpoverhaul.mixin",
 "compatibilityLevel": "JAVA_16",
 "mixins": [
    "GearKeeper"
 ]
}

如果你已经正确设置了所有内容，你的 mixin 现在应该被加载，并且当玩家死亡时应该执行 dead 方法中的代码。 DamageSource.getName().toString() 然后应该记录杀死玩家的东西的名称。

希望这个答案有效✨✨
