I found the reason why demos stop npcs from stuttering!
Through some testing I've found out that if cl_localnetworkbackdoor is set to 0 it has the same effect on npcs as recording a demo. cl_localnetworkbackdoor is a network optimization that sits between the client and the internal server. It works by limiting the number of packets the server sends to the client. From what I can tell it doesn't really matter if you turn it off since this optimization was almost certainly made to squeze as much performance as possible out of older systems.

The npc doesn't follow me through portals, for some reason.

i verbally abused him

fun little dude. when he stole my elevator i was like >:O ... It would help if we could direct the guy with a simple interaction or two? Something like press a key to start/stop following, maybe one to tell him to move from far away. I dunno how easy this would actually be to implement but currently you spend more time trying to position him than solving the test.

Factum Solus 2

i need more

I gotta say, it's a neat idea, but I ended up rage-quitting because it's impossible to get him to do what you want.

It fixes the walking/running animations but I have no idea why

Do you know why you have to record a demo to fix the NPC issues?

i have fren :)

Yeah, it was never going to be perfect. Most of the support for humanoids is removed in Portal 2, and this was made using only hammer logic, no vscript. I was drawn to it for the challenge and I love a good problem to workaround. What's important is that I had fun making it and it's completely playable, as well as being a one of a kind achievement I hope will inspire people to experiment more with humanoids in Portal 2.

Cool idea, although it is really hard to complete the map because of how the NPC acts. I understand completely that it would be hard to code an NPC, but this thing is weird. It also has gone through doors and laser fields, which I don't know if that's supposed to happen, but it's kind of weird. Despite this, it is a well built map, and I'm sure it took you good time and thought. I just know that the NPC was meant for Half-Life rather than test solving. Thank you for the map. 8/10

Really funny, two lifts

is there some way to actually control the guy?

There is some chance NPC navigation could be somewhat smoother actually.

VScript from what I've seen is very powerful, so if someone skilled enough could sit down and figure out a basic navigation system for NPCs, it could really help with making stuff like this a smoother experience.

This is impressive considering most people thought this stuff would be impossible after the generic_actor entity broke, although it does demonstrate how important info_nodes are to NPCs in Source since in Portal 2 they are disabled. While the NPC is functional, it does reek of Hammer jankiness and is hard to play with, although not much that can be done in that aspect.

I do hope this can bring in a new age of walking human NPCs for scripted sequences, maybe even original characters?

If you're still within his range 2 seconds after he moved onto a button, he'll start following you again. Make sure you're backing away from him as soon as he's on a button, and that you're not getting too close to him if you don't want him to start following you again. Keep in mind he won't stay on the button in the room you meet him in

This is a amazing idea you should make more maps like this one

how do you get him to stay? He keeps moving off the buttons.

Not sure what the problem you're having is, move away as soon as you've gotten him to walk over a button and he'll stay there

this map does not work if the human keeps following me

This was a blast! It felt like I was trying to wrangle a human-shaped cat.

SERIOUSLY impressive, love this guy
