A Button is a one-shot trigger. When the operator clicks it, xRLive fires a bound event in Blueprint with no value payload — the press itself is the signal. Use it to activate scene sections, start sequences, fire alerts, or trigger any discrete action that does not need a continuous value.

​
Configuration

Buttons are declared inside UICategories on the xrlive_UIpanel component. Set Type to Xrlive Button and fill in the fields below.

​
Blueprint API

Call Find Control by Name on the xrlive_UIpanel reference, passing the button’s Name. Feed the Return Value into Bind Event to On Button Click. Create a Custom Event and connect it to the Event pin.

A Custom Event node named OnButtonClick_Event is connected to the Event pin. The custom event has only an execution output pin and no data pins.

The custom event has no data output pins. The button press is the entire signal — place your action logic directly after the event node.

Variants

​
Back Button

The Back Button is a navigation variant of the standard button. It is intended for visuals that present operator categories one at a time — instead of stacking all categories in a scrollable list, the visual shows a single category per view and uses a Back Button to let the operator return to the previous view. The Blueprint wiring is identical to the standard button: Find Control by Name → Bind Event to On Button Click → Custom Event. The navigation behavior itself is implemented in the event handler logic.
