What do you mean it makes me grow up?
Your character will start at around 1.65m (5'5") and will slowly grow to a random height between 1.65m (5'5") and 2.10m (6'11") over the span of 24 real-life hours. You basically age!
This datapack changes your pehkui:base size, which means that your stats will slightly change too, it isn't only visual.
Everything is customizable through commands as detailed below.
After changing the config, run /function grow_up:init to apply them and re run everything
Config (click for more details)
/scoreboard players set global adtmylgu.starting_size For example /scoreboard players set global adtmylgu.minimum_size 90000000 corresponds to a default scale of 0.90 for Pehkui (and is the default value). /scoreboard players set global adtmylgu.minimum_size For example /scoreboard players set global adtmylgu.minimum_size 94000000 corresponds to a minimum scale of 0.94 for Pehkui (and is the default minimum value). /scoreboard players set global adtmylgu.maximum_size For example /scoreboard players set global adtmylgu.maximum_size 110000000 corresponds to a maximum scale of 1.1 for Pehkui (and is the default maximum value). /scoreboard players set global adtmylgu.duration For example /scoreboard players set global adtmylgu.duration 86400 will make the player reach it's final height in 86400s (which is equivalent to 24h, the default value).Enjoy :)
