placing arbitrary npcs on line guides is not possible in vanilla smbx. you can use the following lua code (make a file called "luna.lua" inside your level folder and place the code in there) to change the properties of given npcs and make them follow line guides:
Code: Select all
local lineguide = require("lineguide")
local npcList = { 1, 2 } -- insert the ids of the npcs you want to put on line guides here
lineguide.registerNpcs(npcList)
for instance, this code makes the brown and red smb3 goombas follow line guides when placed on them.
do note however that this is a pretty hacky solution and will invariably cause issues with some npcs for which this behavior is not normally intended.
