There is damagers now, but you could do green seeds or with blocks it’s like item profile thingy (I forget what it’s called) → green seed and blocks set property “amount of seed” to the amount of item (the green seeds) and then damager block code “do “amount of seed” damage to Triggering player” then have zone that flashes on and off and when player enter zone give green seed this will multiply with the amount of seeds.
