What is your suggestion?

This would be a good feature if u can make pehkui that if u are bigger then the entity u can pick it up and maybe throw it or carrying it and another if u are big and a player is small u can walk on it and the player that is small gets damage by the big player

Partial duplicate of #183. Unfortunately this is out of scope for Pehkui itself. Though it would be interesting to see some sort of Pehkui addon mod that does this.

@Virtuoel There is a mod that can do it but it is out of date it doesn't support 1.20.1 but u can maybe use the code to implement it into pehkui
