java - Minecraft Player On World 加入活动

Question

我是 Java 新手，我如何处理当前玩家加入世界的问题？

package page.a0x77.kubecraft;

import net.minecraft.block.Block;
import net.minecraft.client.Minecraft;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.Item;
import net.minecraftforge.client.ClientCommandHandler;
import net.minecraftforge.event.RegistryEvent;
import net.minecraftforge.event.entity.EntityJoinWorldEvent;
import net.minecraftforge.event.entity.player.*;
import net.minecraftforge.fml.common.event.FMLInitializationEvent;
import net.minecraftforge.fml.common.event.FMLPostInitializationEvent;
import net.minecraftforge.fml.common.event.FMLPreInitializationEvent;
import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;
import net.minecraftforge.fml.common.Mod;
import net.minecraftforge.fml.common.gameevent.PlayerEvent;
import net.minecraftforge.fml.common.registry.GameRegistry;

@Mod(
        modid = Kubecraft.MOD_ID,
        name = Kubecraft.MOD_NAME,
        version = Kubecraft.VERSION
)
public class Kubecraft {

    @SubscribeEvent
    public void playerLoggedInEvent(EntityJoinWorldEvent event) {
//        ClientCommandHandler.instance.executeCommand(Minecraft.getMinecraft().player, "your command");
            System.out.println("TEST");
    }

}

我想在玩家加入时进行自动身份验证，在加入时发送消息聊天。

Answer 1

你应该使用：

@EventBusSubscriber
public static class Class {
  @SubscribeEvent
  public static void onEvent(EntityJoinWorldEvent event) {
      if ((event.getEntity() instanceof PlayerEntity)) {
        LogManager.getLogger().info("Joined!");
      }
  }
}

我想也许你需要播放器的实例才能让它工作。
