How do you make NPCs follow you?

[tHe owV3rLOAdaH]

How do you make HL2 characters follow you without making that NPC "citizen" type.

example:

Alyx
Barney
Kleiner
Gman
Father Grigori
and more other npcs.

Im pretty sure there's somehow a script or a command for it,
I just don't like HL2 citizens being killed so fast.

Is there a way you can add more people following you instead of 4?

Unless Dan's SNPC Pack has a friendly npc that's strong and follows you (I can't remember at all if it does, if it does, I think you could just change the model and name) then you'd have to stick with the NPC "citizen/rebel" type, as there are no other default forms of AI that follow you and are stronger that come with Garrysmod.

And I'm not sure about more people following than 4, it's been like that for a long time, but perhaps you could override it in lua which I don't know how.
