Age of Block/Entity (Expression) — Skript
Addon: Skript · Category: Expression · Since: 2.7
Syntax
[the] [max[imum]] age of %blocks/entities%Description
Returns the age or maximum age of blocks and age for entities (there in no maximum age for entities). For blocks, 'Age' represents the different growth stages that a crop-like block can go through. A value of 0 indicates that the crop was freshly planted, whilst a value equal to 'maximum age' indicates that the crop is ripe and ready to be harvested. For entities, 'Age' represents the time left for them to become adults and it's in minus increasing to be 0 which means they're adults, e.g. A baby cow needs 20 minutes to become an adult which equals to 24,000 ticks so their age will be -24000 once spawned.
Examples
# Set targeted crop to fully grown crop
set age of targeted block to maximum age of targeted block
# Spawn a baby cow that will only need 1 minute to become an adult
spawn a baby cow at player
set age of last spawned entity to -1200 # in ticks = 60 seconds
