nav_generate

that generates a navmesh not ai nodes

Greetings stranger, I am from the future and I am here to inform you that Cpt. hazama has appearently made a nodegraph for this map. It's only on github though. Here's a link to his nodegraph collection: https://github.com/Cpt-Hazama/My-Nodegraphs/tree/master/maps/graphs .
If you don't trust links you can instead search for Half life resurgence on google, go to the github page, click on Dr. vrej's profile, go to his stars and look for "Cpt-Hazama / My-Nodegraphs". You can either download the entire collection by pressing " <> Code " and then "Download ZIP"
or you can instead click on the "maps" folder, then "graphs" there you can see all individual files,
then you have to search for the correct file, it'll be called "rp_desert_strike.ain", click on it, click on the little download button. Now, you gotta manually put it into the right folder, you gotta open one or two file explorer windows and put the file from your downloads into the C:\Program Files (x86)\Steam\steamapps\common\GarrysMod\garrysmod\maps\graphs directory.

Now, I'm sorry to say this but, even after all of that ♥♥♥♥♥♥♥♥ there's a good chance that it wont work because of some ♥♥♥♥♥♥ source engine quirk where if there's an .ain file already integrated into the map's .bsp it will override any custom ones. You can try typing ai_norebuildgraph 1 into the console before launching the map to fix it but that might still not work.
The last time I tried this it didn't work for me, altough that was already a while ago so I might not remember it correctly.

But hey, atleast you know how to work with .ain files in general now and you know of a long, LONG list of .ain files for maps you potentially wanna use npcs on.

Actually, there still is one way you can add the node file to this map if the conventional route doens't work, it's a dark path though, something the Jedi wouldn't show you. You can try to Decompile the map and Pack the nodegraph into the map for yourself I have never tried this myself so I couldn't tell you the exact details of how to do it. Oh, and there's also this tool that claims that it can create a nodeable version of the map you're playing but I didn't quite figure out how to do that yet. https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=3004697874&searchtext=nodegraph
