Event or Function for any structure in focus (like interact menu)

does an event or interface exists, which returns the structure in focus of the player (like the interact menu does)?

i have tried with line trace, but it would be easier and better for the performance if such an event or another way (for example an interface) exists.

btw. a list with all interfaces and events referring the ark engine (not the unreal system) would be a great help.
