Minion Spell

Spell subclass that lets you create minions based on a specific mob. Passing the minion type (mob) to the constructor.

This spell subclass is heavily simplified thanks to Minion Data System, check this to know more info about how the system works.

By default, minions spawn on ground, but you can use the flying(bool) to spawn minions in the air instead.

If you want to add extra conditions for the use of the spell you can use the extraConditions() method to add your new conditions, changing the return result based on your conditions.

Need to define the DefaultProperties.MINION_COUNT(normally set to 1, but if you want a group of minions you can use this!), and DefaultProperties.SUMMON_RADIUS to define the max radius for minion's spawn. If you don't define these properties the spell might not work properly.

TIP

Minion Spells are the one of the few spells that doesn't need sending packets to the client! At least in normal cases

If you want to add custom data to these minions dynamically (like adding armor/artifacts depending on cast context) you can use addMinionExtras().

Example using the Summon Skeleton spell. Setting AbstractSkeleton - EntityType.SKELETON as their minion, giving the possibility to use Skeleton subclasses. Creating a Stray or a normal Skeleton depending on if the player has a specific artifact and spawning with a bow in main hand.

java

public class SummonSkeleton extends MinionSpell<AbstractSkeleton> {
    public SummonSkeleton() {
        super((l) -> new Skeleton(EntityType.SKELETON, l));
    }

    @Override
    protected AbstractSkeleton createMinion(Level world, @Nullable LivingEntity caster, SpellModifiers modifiers) {
        if (caster instanceof Player player && EBAccessoriesIntegration.isEquipped(player, EBItems.CHARM_MINION_VARIANTS.get())) {
            return new Stray(EntityType.STRAY, world);
        } else {
            return super.createMinion(world, caster, modifiers);
        }
    }

    @Override
    protected void addMinionExtras(AbstractSkeleton minion, CastContext ctx, int alreadySpawned) {
        minion.setItemSlot(EquipmentSlot.MAINHAND, new ItemStack(Items.BOW));
        minion.setDropChance(EquipmentSlot.MAINHAND, 0.0f);
    }
}
