The Node-O-Matic 3000 was a non-public mod I made to help find action nodes using a sort of brute-force guessing method. It was very laggy and experimental, so I never officially released it, however I had no problem with people spreading it. How it worked was simple:
1. There was a list (a table) of nodes (strings).
2. This list would be used to make different combinations of full node paths and use
PedIsPlaying to check if the player or target was playing any of the combinations of the list the mod generated.
3. If the player or target was playing any, the node would get printed. It usually was not "full"/executable, but it was still helpful for using with
PedIsPlaying and for starting to find "full" nodes.
Depending on how many nodes were in the list, the mod could get very laggy. This is why when using the mod, it is suggested you only use a small list of nodes you think could be related to the one you are trying to find (by small I don't mean like 20, I mean just a few 100 at most).
