[SOLVED][1.12.2] Override an existing entity


Sunser

Recommended Posts

Hi all,

I've been looking a few on the web but I haven't found enough informations. I would like to override the existing snowball entity (actually I want it to be turned into a projectile). I quickly looked on the Railcraft's Github but I lost myself (I thought it replaces the simple track). Any ideas? :/

So I implemented a little event handler :

Spoiler

package com.moresnowballs.moresnowballsmod.event;

import com.moresnowballs.moresnowballsmod.entity.EntityCustomSnowball;
import net.minecraft.entity.Entity;
import net.minecraft.entity.EntityLivingBase;
import net.minecraft.entity.projectile.EntitySnowball;
import net.minecraft.world.World;
import net.minecraftforge.fml.common.eventhandler.EventPriority;
import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;

public class EventHandlerServer {
    // Gestion des events coté serveur
    @SubscribeEvent(priority = EventPriority.HIGHEST)
    public void EntityJoinWorldEvent(Entity entity, World world) {
        if (entity instanceof EntitySnowball) {
            // creating new entity
            EntityLivingBase thrower = ((EntitySnowball) entity).getThrower();
            EntityCustomSnowball entitysnowball = new EntityCustomSnowball(world, thrower);
            entitysnowball.shoot(thrower, thrower.rotationPitch, thrower.rotationYaw, 0.0F, 1.5F, 1.0F);
            world.spawnEntity(entitysnowball);
            // killing old entity
            world.setEntityState(entity, (byte)3);
            entity.setDead();
        }
    }
}

 

I've registered it in my server proxy :

Spoiler

@Override
    public void init(FMLInitializationEvent event) {
        MinecraftForge.EVENT_BUS.register(new EventHandlerServer());
    }

 

I've made a few tests and the handler is not working. What did I fail ?

Here's the function :

Spoiler

@SubscribeEvent(priority = EventPriority.HIGHEST)
    public void replaceVanillaSnowball(EntityJoinWorldEvent event) {
        Entity entity = event.getEntity();
        World world = event.getWorld();
        if (entity instanceof EntitySnowball) {
            if (!world.isRemote) {
                // creating new entity
                EntityLivingBase thrower = ((EntitySnowball) entity).getThrower();
                EntityCustomSnowball entitysnowball = new EntityCustomSnowball(world, thrower);
                entitysnowball.shoot(thrower, thrower.rotationPitch, thrower.rotationYaw, 0.0F, 1.5F, 1.0F);
                world.spawnEntity(entitysnowball);
                // killing old entity
                world.setEntityState(entity, (byte)3);
                entity.setDead();
            }
        }
    }

It correctly summons my custom entity but the vanilla one is still visible a few ticks.
