Nodegraph Editor Expansion

Please review the official Valve developer wiki on nodegraphs before noding! Nobody wants to play on a map with a poopy nodegraph! Make sure you also unsubscribe from any other nodegraph editors!

This tool allows users to easily create nodegraphs for maps that do not already have an existing nodegraph. When the node limit was first increased, I immediately updated the tool and started working on more features. I never got around to releasing them but they were on my github for several months. The features were never fully finished but I will add them back in my spare time. Currently you can create ground nodes and air nodes. Climb nodes exist but they do not function so it is recommended to not use them at the moment. It is recommended that you only create a nodegraph if you know how to properly node a map. Creating a bad nodegraph creates a bad experience for anyone who plays on the map. If you need an example of how to node, go look at Valve's nodes, my nodes or DrVrej's nodes.

• Choosing your node type
  
• Adjusting node links
  
• Grid snapping
  
• Draw distance for nodes local to your cursor
  
• Maximum linking distance for nodes (please keep the link distance between 300-450, any higher will cause confusion in AI)
  
• Node yaw/height adjustment
  
• Tells you what node you're currently on, the total number of possible nodes, as well as warning you when you get to close to the node limit
  
• Can generate a semi-nodegraph using a nav-mesh as a reference (WIP)
  
• Reorganized menu from the original

After you save your nodegraph, it will save in your "Garrysmod/garrysmod/data/nodegraph/" folder. It will be saved as a .txt file named after the map. To use your nodegraph, you have to rename the .txt file extension to .ain and put it in your "Garrysmod/garrysmod/maps/graphs/" folder. Type restart in your console for the changes to take effect. If you're uploading the nodegraph, the folder structure would be the same as any addon: "Garrysmod/garrysmod/addons/ADDONNAME/maps/graphs/"

Note that if the nodegraph doesn't save, that means the map has a built-in nodegraph file. To get around this, use a hex editor (I use HxD) and search for all instances of ".ain" and change one letter in the ain file's name. After all of the instances are changed, save the file and your nodegraph will work! Example: two instances of "maps/graphs/gm_mapname.ain" in the BSP file, change them to "maps/graphs/ga_mapname.ain" and save. Note that no extra or unique characters should be used, or the file will become corrupted. Also since the file is packed, it wont load outside of the map itself so don't worry about name conflictions.
