Kh
1

I saw an order in a Minecraft video. The command is "mysize" and then a number but then it says that this command is not possible. Hope one of you has Anung there.

Ke

/ mysize (/ ms) command to change the player's size. / basesize (/ bs) command to change another player's size. Climbing blocks while holding a slimeball if small. Gliding while holding paper while small.

…

Requirements:

ArtemisLib (version 1.0.6 or later)

Minecraft Forge (version 14.23.5.2795 or later)

Minecraft (version 1.12.

Hope I could help you.
