Hi Eric,
It’s a good sign that the example project works, that means that we should be able to get your existing project working as well.
So, let’s go step by step. Can you confirm that you followed all the steps provided in the README for how to import the plugin to your own game project?
To import the plugin into your own game project:
- Create a new directory in your Unreal project directory called “Plugins”.
- Copy the contents of the Plugins directory in this repository into that directory.
- Start the editor and open the plugin viewer (can be found in the Windows->Plugins menu).
- Add a reference to the module in your build script (MYPROJECT.Build.cs). The relevant row might look something like:
PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore", "TobiiEyeX" });
Second question: Are you using the EyeX function library (Blueprints) or the IEyeXPlugin interface (C++)?
