When I'm trying to spawn entity my server is shutting down and throws this:

> [08:41:38] [Client thread/ERROR] [FML]: A severe problem occurred during the spawning of an entity at ( -260.46875,64.0, 223.84375)

        this.motionY = tag.getDouble("motionY");

        this.motionZ = tag.getDouble("motionZ");

    }

 

    protected void entityInit() {}

}

 

 

I tried to add constructor without arguments, but this changed nothing. Here's how I'm registering it:

@EventHandler

    public void Init(FMLInitializationEvent event)

    {

        EntityRegistry.registerModEntity(mEntityFireball.class, "mFireball", 1, instance, 80, 1, true);

    }

 

 

 

I added another entity based on EntityCreature and it works good. Where is the problem?

But how does original minecraft fireball works? It is abstract too

public abstract class EntityFireball extends Entity

and contains

protected abstract void onImpact(MovingObjectPosition p_70227_1_);

Here's my instantiation:

mEntityFireball fireball = new mEntityFireball(world, entityPlayer) {

                @Override

                protected void onImpact(MovingObjectPosition p1) {

                    if (p1.typeOfHit == MovingObjectPosition.MovingObjectType.ENTITY) {

                        p1.entityHit.attackEntityFrom(DamageSource.causePlayerDamage(entityPlayer), damage);

                    }

                    setDead();

                }

            };

 

and it works with vanilla EntityFireball
