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

        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_);

    • Author

    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
