How do you add monsters to a multiplayer game? Like in the original half-life, the level Snarkpit, when you push the button and the snarks spawn in from the pipe. I tried decompiling it but still cannot find out how they did it. Whenever I try to put monsters in and when I play in multiplayer they do not show up. Thanks.

It's done by using the "monstermaker" entity. I'll help you further tomorrow, then I have some time smiley

Yes, I will need your help more, because I tried using the monstermaker entity and the monsters still do not work.

Ohh sorry I haven't gotten back to you, I'll be honest I didn't really think about it anymore. Sorry!

I got it to work on my map, this may help a bit: http://twhl.info/entity.php?id=210

In the entities properties, the name of the monster you want to spawn should go into the "monstertype" box. For example: monster_snark

Just let me know when you still can't get it to work.

Oh by the way, it doesn't work with some mods, like Botman's Bots that I used in the past.

I was able to get it to work with the snarks. BUT I was not able to get it to work with headcrabs or zombies, which is what I really wanted. Is there any way to make it work for these monsters as well and not only just for snarks? Thanks.

This is for Half-Life Opposing Force.

Hmm that's odd. So, "monster_headcrab" didn't do the trick?

I hope someone else comes in to help you here, as I have no idea what to try next. I'm sorry! smiley

Unfortunately no. But thanks for your help though, the snarks worked, but not the others. Maybe they're not allowed in MP. No idea why though.

Accepted Answer
I don't think there is AI that's programmed into mutltiplayer. I think in the case of the snarkpit map it spawns the output of the snark "weapon" and it goes from there. So I don't think you can add npcs to the level - the network synchronization over AI states would be a nightmare to code, so therefore npcs aren't possible in hl1.

In my map, I used a monstermaker as well to spawn the snarks.

Or does that not say anything?

But snarks are weapon items. There is AI for weapon snarks in multiplayer.

No that is true but I was just pointing out that I got it to work using the monstermaker, I didn't know if that was against your theory or not.

I think monster_tentacle is also available in multiplayer by the way, but I am not entirely sure.

It is - and thats how snarks are able to spawn from the map. But you can't spawn just any old NPC.

I know this is an old topic but I had to correct the misconception that only snarks work in MP. I have had just about all of the monsters in MP. The trick is to first set up the entities correctly and while testing the map type mp_allowmonsters 1, then restart the map. type restart in console. I'll see if I can find the time to post the entity set up in the near future. BTW maps ran on a dedicated server have allow monsters set to 1 as a default, its when you run the map on your pc while playing it is set to 0. Snarks work either way because they are also a weapon.

Also, is there a way to make it so that players cannot hurt each other in multiplayer if you want a strict coop map? (Although SvenCoop would probably be a better choice anyway though)

I believe when I posted this question I did not even have SvenCoop yet, so you don't have to post the entity setup. I actually have gone back to mapping for single player projects now. I go through phases, but now it's off to single player!

Hi! Afaik you just need mp_allowmonsters 1 and then all monster-entities should work perfectly fine in multiplayer.
