Modding Help "interactAction" Usage

Anyone know whether the actual action is defined in C++ or available to be defined in lua or JSON files?

Any documentation on a Lua API? If not anyone know the function to set a players position?

 

I'd look into the LUA for the Blink tech, which changes the location of the player.

 

Thanks for you help.
