I try to get the pupil diameter data in Unreal/ C++ which is not included as a function in the SRanipal_FunctionLibrary_Eye. That's the reason why I tried to directly get the verboseData or EyeData through SRanipal_Eye eg. like this:
int result = SRanipal_Eye::Instance()->GetEyeData_(&eye_data)
For some reason I always get the compiler error "error LINK2019: unresolved external symbol". So far I could not work out my mistake so I would be very grateful for a short example/ code snippet on how to access the pupil diameter data in Unreal/ C++ with SRanipal (not Tobii!).
Thanks in advance
