EffectiveThrowable

Behaviour that lets an EffectiveItem be thrown as a snowball-backed projectile.

Registration adds a right-click handler that launches the projectile carrying the item; a shared module listens for ProjectileHitEvent and dispatches to the matching item's onHit. Register via EffectiveItem.makeThrowable.

Notes:

• The projectile is always a Snowball; the thrown item is stored inside it and used to identify it on landing, so EffectiveItem.createItemStack must yield the item's namespaced key (the default does).

• onHit is already filtered: it fires only for this item's projectiles, never for vanilla snowballs or other throwables.

fun init() {
    makeThrowable(velocity = 1.5) { event ->
        val target = event.hitEntity as? LivingEntity ?: return@makeThrowable
        target.addPotionEffect(PotionEffect(PotionEffectType.POISON, 40, 0))
    }
}
