I'm trying to create a custom node to use in ORK Events. I've seen from your previous posts that I should copy an existing node from the source code and edit it to my needs, so I tried that and just changed a couple text strings to see if it would show up in the editor.
I was following this guide
and when it came to adding references, I had trouble finding the UnityEngine.Ui.dll in the given pathway (running Unity version 2019.4.4f1). So I tried a few versions of that file found in other pathways within that Unity folder, and I also downloaded a clean version of 2017.4.40f1 and used that UnityEngine.Ui.dll. I had to comment out some dated references to things like the ParticleEmmitter component and the WebPlayer application to get it to compile in Visual Studio. I then replaced my current version of the ORKFramework.dll with the version I edited, and I couldn't even open the ORK Framework window in Unity. Even after changing back to the unedited ORKFramework.dll, it wouldn't open the ORK Framework window until I loaded my backup.
Am I going about this all wrong? What steps should I be taking to create a custom node?
