https://youtu.be/qTY9LPwe17Q Thanks to your help I was able to make this Gmod Realism video so the combine ai would actually behave properly on the "Dog Red" Day Of Infamy Omaha beach map that didn't previously have nodes I simply generated them and saved them and followed the instructions after I generated my own optimized Navmesh first using Navmesh Optimizer mod. "Gmod Realism: Rebels Defend Beach From Combine Assault!" is what I managed to create thanks to your genius tool. The combine now understand how to ferociously fight, and shoot long distance and manuever and take cover on the Omaha beach as they push up to try and take my position against my MG42 and my Rebel teammates M60's.

This is a genius addon because now maps with no ai nodes can now be generated to have ai nodes with custom settings and a tool to edit it. Literally game changing for even the average user or better yet advanced users.

It's on the tool menu.

Wait really? Where is this ground node generator you have me intrigued? I can generate my own navmeshes using navmesh optimizer mod or whatever it's called to generate my own navmesh so that's not a problem. I really want to learn how to do this exactly as being able to generate my own ai nodes would be game changing.

Well, there's ground node generator if that's what you're asking. It needs navmesh, though. Set the nav min area size to 0 and it will basically converts your navmesh into nodegraph.

I love the idea of this! One request thing for us novice users however and I have no idea if its even possible. But as an example for Navmesh Optimizer mod... it allows us to generate a complete optimized navmesh for the map with simply 2 console commands.

I wish it was that easy for Ai Nodes... a simple console command that allows me to generate a decent rough one for a map that doesn't have nodes. That would be a life saver and would save me a lot of trouble and time as a Gmod Realism content creator.

I will consider your tool however. You made something pretty genius here upon improving the O.G tool.

the mod is extremely well done

That's not how nodegraph works, unfortunately.

Consider adding func_door support. I.e enable linking nodes to the door, with the tool gun, so that NPCs know/have to open it before traversing the links.

how to use hint nodes?

It has already been implemented and will be available in the next update.

I recently convinced the author of HintNode Loader to add Jump Up support to Hint Nodes. Would you be able to add Jump Up support to your editor? You can do this by adding "SpawnFlags": "65536" to each node that wants Jump Up support. I manually edited the hint.json files you generate to have this SpawnFlags field, and Jump Up works as desired.

Beause the engine can't handle more. Remember, source is from 2004

Why is there a limit to the amount of nodes you can place?

hello again! the next time i loaded the map, it somehow worked without problem, leaving me kind of embarrassed. i can only guess that maybe starting the game from the start might have helped, but since i had already tried that, i'm at a loss... thanks again for your help!

No problem at all. I recently tested out the map, and the custom nodegraph I've made works correctly without problem. After you created your custom nodegraph and installed it correctly, the game shouldn't rebuild the nodegraph. You can try recreating your nodes from txt and resave, as the tool will attempt to update the nodegraph with the latest map version which prevents nodegraph rebuilding.

thank you for the fast reply! i forgot to mention it, but i did try that as well with the same file path format in it and having norebuildgraph enabled (otherwise it does just that). just in case, i tried again, but to no avail. i noticed that the tool shows the error "the nodegraph file in data/nodegraph differs from the map's nodegraph", which i guess means that the map keeps replacing it with its own. sorry for the trouble!

@Ligma The tool did correctly detect that the map is nodeable. I've checked the map's bsp myself and there is no embedded nodegraph file inside. This is probably another case of custom nodegraph files being replaced by the map's addon files as there is an empty nodegraph file uploaded alongside the map. If you read the Usage section in the description, you can fix this issue by placing your custom nodegraph file inside addons folder instead of directly in the maps/graphs folder. If it still doesn't work, let me know.

hello, i've been having problems with a particular map, https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=797619787 . the map's description says that it is already ai noded, but checking in game it seems to not have any nodes, node-using addons don't work (e.g. zombie/npc invasion+), and the tool says it is already nodeable. however, when i generate a nodegraph for it, rename it and put it in the graphs folder, and reload the map, it always has the empty nav mesh. i've also noticed in my various attempts that it often says that it's rebuilding the mesh, and even if i put the no rebuild command or make the navmesh read-only it still doesn't have any nodes. uninstalling and reinstalling the map didn't help, either.
other than perhaps some help with this, i would like to ask, could you make it so you can make a nodeable version of the map regardless of if the tool detects it as nodeable or not? thanks!

Nvm, I just found out that the nodes were saving in another hard drive that my GMod files used to be.

now

strider work ?

Saving a nodegraph on maps (at least for me) isn't possible anymore. It worked fine at first, but now whenever I save, it says it successfully saved, but there's nothing in the nodegraph folder. The map I was trying to save is already nodeable. Even trying it on other nodeable maps won't save the txt file. It could be an addon conflict but I don't know if any of the addons I installed conflict with this one.

@TheBlackVoid Thank you, everything started to work.

@Райдер I recently updated the tool, and I hope this resolves your issue. Please try again.

@TheBlackVoid As soon as I free up, I will send the video.

Okay. I never came across this issue at all, so I can't really give you a solution. Maybe you can send me a video recording or something so I can probably understand more what happened.

@TheBlackVoid This happens on any map.

I'm not sure what the problem is, really. You can add me and send me the map link and the nodegraph (.ain) file, so I can look into it.

@TheBlackVoid I can't load the AI nodes at all. Everything is within the limit.

This error happens when the node count is below 0 or above the maximum limit. The limit was increased from 4096 to 8192 in the latest update, so please make sure your game server/client are fully updated.

AI node graph maps/graphs/anomaly_server_2.ain is corrupt

what the error?

(game crash and open window error)

@Райдер Probably a really bad addon conflitct, or the mod just didn't load correctly.
Have you tried restarting the game yet? If that doesn't help disable all your mods except for this one, close and open the game again and load into a map

I take the tool in my hands and until the moment of loading the AI nodes, there is a strong infinite lag, which prevents me from closing the task manager in Garry's Mod.

This tool is for creating nodegraphs (aka AI Nodes), which are used by base G-Mod NPCs as well as NPCs from other bases like VJ Base. While DRG Base NPCs (or NextBots) rely on a navmesh to function. There are two different navigation systems due to NPCs and NextBots using different kind of AI.

@AKASO EK7000 Pro 4K
I think that you want a navmesh and not a nodegraph, because as far as I know DRGbase NPCs are technically nextbots that don't use nodes at all

Here's the easy navmesh editor:
https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=527885257&searchtext=navmesh+editor

does drg base work with this, if not what nodegraph editor does

alright thanks

The button is only visible when the map is not nodeable.

am i blind? i can't find the "Create Nodeable Map" button anywhere

Can't wait for the updated tool, this allows much more meticulous nodegraph creation now.

I rarely play GMod nowadays, but thank you for letting me know. I will update the tool once the update is released.

idk if you saw but the upcoming GMod update features 8192 as the max node count

like how i can use Create Nodeable Map?

iam having a problem. after the ,ain process and saving and using ainorebuildgraph 1 the npcs freezes and stop working

Enter the command "ai_norebuildgraph 1" before loading into the map to stop the game from rebuilding the non-existent nodegraph.

I know what to do, but no matter what I do the nodes don't show up after creating the .ain file (and reloading the map). I'm not sure if I'm doing something wrong or if it's the map itself.

the addon doesnt save the nodegraph and the "garrysmod\data\nodegraph" (specifically the nodegraph folder) does not exist

That's why Create Nodeable Map feature exists. :)

Got it thanks.
Only problem now is map devs who compile their map with a 1kb.ain file that prevents you from using AI nodes.
God forbid Map makers take the effort to compile a cubemap.
Putting 1kb.ain into the map is a bigger sin because thats just a conscious choice

For hint nodes, put the hint node json in the same directory as the .ain file (maps/graphs). Make sure HintNode Loader addon is installed, and then set both ConVar "sv_enable_init_hint_hook" and "sv_enable_hint_json_load" to 1, and reload the map.

Also, the addon sets "ai_norebuildgraph" to 1 for some reason. So, if you wonder there's no nodegraph on maps that's supposed to have, disable the addon and set "ai_norebuildgraph" to 0, and reload the map.
