Right now there is no way for creators to allow players to interact with circuit programming by pressing buttons on their controller hardware (VR controller, mouse, gamepad, etc.)
This need is most clear with the trigger buttons or mouse clicks. Players can use that button to do almost any interaction in Rec Room, but creators don't have a way to create their own interactions.
Some kind of function in circuits V2 that read player controller input and outputted circuit signal would be extremely powerful.
This could be a specific gadget that outputs signal when held, or more directly a chip that reads a player's controller input regardless of what they're holding.
