I have a custom entity which I want to add particles to the world at its position, both on each tick, and on impact.

My entity does spawn, and the impact is detected, however, no matter what I try, I cannot create particles.

public class SpellEntity extends ThrowableEntity {
    public SpellEntity(EntityType<? extends ThrowableEntity> type, World worldIn) {
        super(type, worldIn);
    }

    public SpellEntity(World worldIn, PlayerEntity playerIn) {
        super(ModEntityTypes.SPELL_ENTITY.get(), playerIn, worldIn);
    }

    @Override
    public void tick() {
        super.tick();

        if (world.isRemote) {
            this.world.addParticle(ParticleTypes.FLAME, this.getPosX(), this.getPosY(), this.getPosZ(), 0.0D, 0.0D, 0.0D);

        }
    }

    @OnlyIn(Dist.CLIENT)
    public void handleStatusUpdate(byte id) {
        if (id == 3 && this.world.isRemote) {
            for (int i = 0; i < 8; ++i) {
                this.world.addParticle(ParticleTypes.FLAME, this.getPosX(), this.getPosY(), this.getPosZ(), 0.0D, 0.0D, 0.0D);
            }
        }

        super.handleStatusUpdate(id);

    }

    protected void onImpact(RayTraceResult result) {
        if (!this.world.isRemote) {
            world.createExplosion(this, this.getPosX(), this.getPosY(), this.getPosZ(), 2F, Explosion.Mode.BREAK);
            this.world.setEntityState(this, (byte)3);
            this.remove();
        }
    }

    protected void registerData() {

    }

}

Any help would be much appreciated.

A lot of data is not stored on the client. Since you are not throwing an error, I can assume the ClientWorld is not null on your entity. However, the position of the entity may not be. You can verify this with a breakpoint. If so, you can pass the data using a packet from the server.

you might find this example project useful; it shows generation of vanilla particles or custom particles. It also shows how to use packets to communicate information from server to client if necessary.

Managed to fix my issues, I was not sending the proper packet to the client. This method was required.

 

@Override
public IPacket<?> createSpawnPacket() {
    return NetworkHooks.getEntitySpawningPacket(this);
}
