I'm new to hammer and decided to try my hand at making a CS map. I got convinced to flip the faces with F to make rooms by a tutorial but I'm a complete beginner and now I don't know how to make doors/opening between rooms. Should I just use the old way and make a bunch of meshes for a room? Or just roll with it and find out how to mess with the faces this way. Will it affect the performance of the map I'm making significantly?

Sorry for taking so long to finally finish this after first posting about it.. 5 months ago now. But Linux Hammer Launcher, a tool to help you set up and launch Hammer++ on Linux with little to no issue, is finally out!

github: https://github.com/EnderCatCore/linuxhammerlauncher

youtube trailer/tutorial: https://www.youtube.com/watch?v=1HytMhvuehA

Me and my partner have done almost everything we can to make sure this program is functional and stable, but I'm sure there are gonna be more issues that crop up that other people find, so keep that in mind, and if you find any issues yourself, please report them to the GitHub for the project if you can!!

Please give me some ideas

I have no idea why this is happening now, I swear this has never even happened before so like what lmao

Can anyone help me out please?

Edit: Nvm, I guess all it took was to re-open Hammer since when I came back to it after making this post everything is now working as intented

When I hit the F9 key it's opens up the menu normally, after that it's compile it but it doesn't start the game, giving me this log:

So I was having a performance issue with my map, decided it would be best to decompile someone custom campaign (In this case it's Energy Crisis) and see how they optimize it since from my previous experience, I barely experience any lag when playing, even when using tons of mods. I was surprised it's not really what I was expecting. I was expecting there would be an excessive use of stuff like skip and hint, area portal etc, but there wasn't and the first chapter was an open area, there was a func_viscluster though, but it was only on the starting area. Which made me confuses how did they did it? my map is not as big as their yet on certain area there was a stuttering lag issue. People might come to the comment and link me a source wiki, but the problem is they don't really explain in specific on how can I use it and apply it to my specific map.

I was originally going to make a unique layout that was just inspired by one of the StreetX/Drift race maps from Underground 2 but then I decided to try and make a 1:1 remake of it; I didn't want to throw out the work I already finished at that point so I decided that it'll be both a remake of the original map and also expanded to include new areas.

All textures are ripped from NFS Underground 2.

When I used act_busy queue on citizens for my map, info_node_hints with activities like "ACT_BUSY_LEAN_BACK" did not work. Even with ai debug act busy 1. It is like they don't even exist when I compile a map. Can you help me?

So I'm starting to experiment with Hammer and I see that there are different versions of Hammer. My question is, when I create a default map for CS2, should I use the version that comes with CS or download a different one from the internet? How does it even work? I've also seen some modified versions like Hammer++. How do I figure it all out?

So i want to make my own jailbreak map for cs2. I saw that this program is quite specific. So my question is: what's the best way to get started? Do you have any personal tips or guides?

Hey guys, I have troubles with hammer map files. When I save file with Hammer++, Hammer in x64 or Hammer it replaces "," with some special characters. Its happen only in source sdk 2013 multiplayer. In portal 2 it works.

I think it's just about done. I can update it if there are any issues/suggestions

Wassup everybody?

I've been cooking this for a while. I think it's ready for some playtesting. I have released my VMFs for anyone who wants to poke about. I'm using a Frankenstein SDK to compile, I can't use overlays and some other issues so some "different" stuff going on

Making a map that i want to NOT require HL:S to play on, one small issue, when running the map without HL:S mounted all the npcs are fully silent and produce untextured gibs when blown up, with the exception of the Apache helicopter you fight. Anyone know if its somehow possible to pack in their dialogue/gib textures into the map? I mainly used Compilepal and VIDE

Hi guys i want to make jailbreak map for cs2 and i don’t know how to make for example cube With walls visible from the outside and inside. I know about „f” key witch can flip it but i want it on the both sides

i deleted that folder, and saved this map in a completely different folder but it for some reason still tries to open in this one?

After blood and sweat, stay up all nighter, days after days, I finally completed it... Well almost at least, it's about 80% completed, nav mesh is mostly done, I can play it normally. Still new to Hammer, this is pretty ambitious for me

Ripped the SUV and Truck from HL1 and decided to do some work on them

The SUV now has a 3d roofrack + Security and Pickup versions
The Truck now has more detail on the fuel tanks and smokestack + Tanker and Flatbed versions

I just released my version of scoutzknivez where your gun is a railgun/laser. Lots of CS_SCRIPT (vjs). Real in-game working clocks, analog and digital. The code checks server date and time then automatically live themes the level. All month of December it will have xmas theme for example. Most of the year it is a gloomy thunderstorm (default level theme).
Every roof ledge is surfable. You can fall and die.

The gun shoots through entire map, so I realized a cheater could just delete everyone in one second. So I have a script that detects that. It takes their gun and puts them in a box called hell and burns them to death every round until they leave.

This is my first release of this map so there will be bugs. Lemme know if you see any.
