Living spawn events. (1.12.2)


Recommended Posts

I have this code:

package com.vova7865.essencecraft;

import java.util.UUID;

import com.mojang.authlib.GameProfile;

import net.minecraft.entity.EntityLiving;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.server.MinecraftServer;
import net.minecraft.world.World;
import net.minecraft.world.WorldServer;
import net.minecraftforge.common.DimensionManager;
import net.minecraftforge.common.util.FakePlayer;
import net.minecraftforge.event.entity.living.LivingSpawnEvent;
import net.minecraftforge.fml.common.Mod.EventBusSubscriber;
import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;



@EventBusSubscriber
public class EventHandler {
	@SubscribeEvent
	public void livingSpawn(LivingSpawnEvent event) {
		if(event.getEntityLiving().toString().contains("Guardian")) {
			EntityLiving living = (EntityLiving) event.getEntityLiving();
			World world = event.getWorld();
			WorldServer serverWorld = DimensionManager.getWorld(0);
			GameProfile gameProfile = new GameProfile(UUID.randomUUID(), "FakePlayer");
			FakePlayer fakePlayer = new FakePlayer(serverWorld, gameProfile);
			MinecraftServer minecraftServer = fakePlayer.mcServer;
			String playerNames[] = minecraftServer.getOnlinePlayerNames();
			String firstPlayerName = playerNames[0];
			EntityPlayer player = world.getPlayerEntityByName(firstPlayerName);
			double x = player.posX;
			double y = player.posY;
			double z = player.posZ;
			living.attemptTeleport(x, y, z)
		}
	}
}

So when the guardians spawn, they teleport to me. They do, but the same guardians are teleported to me multiple times, so I think that LivingSpawnEvent is fired not only when they spawn.

Anyone knows how can I do some code only when the mob spawns?

The LivingSpawnEvent has sub-events IIRC.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

DO NOT PM ME WITH PROBLEMS. No help will be given.

Mobs spawned by the world & mobs spawned by spawners eventually pass through LivingSpawnEvent#checkSpawn before actually getting spawned.
And yes, all children of LivingSpawnEvent will be given to you unless a specific one is stated.

 

Btw, your whole "create a fake-player just to get the server" is quite redundant. Just call World::getMinecraftServer and be done with it.
Creating FakePlayers is dangerous if you don't also make sure to remove them when the world needs to unload, or it's not gonna get unloaded, because the "player" is still in there.
