[Follower] Creature doesn't move

Yakuzashi · September 18, 2018

Hello. I have tried to make followers based on Maxwell's copies. Game doesn't crash. My followers after spawn are just idle. They can die but won't move or act in any way. I coppied maxwell's copies SG and brain so it is not problem. I also modified character and creature prefab files, so they could be troublemakers. I will appreciate every help.

Character

local MakePlayerCharacter = require "prefabs/player_common"

    Asset("SCRIPT", "scripts/prefabs/player_common.lua"),

"shadow_despawn",
