A host-rendered control with a typed no-argument action.
Signature
The host invokes action through Machine::invoke_component. The default noop is intentional; a Button schema never dispatches an action by itself.
Fields
label: Str- Visible label; defaults to Button.Default
"Button"
Examples
Use the default action
The default callback is callable and produces no log output.
Devices
Use this scene on another device
Show a QR code for your glasses, or send a link to another browser. You can keep working here.
Sharing starts a fresh run of the last compiled code. Your editor draft stays here.
Join a session
Open an invitation link, or paste a link or code from the other device.
Connect your other device
On RayNeo, open Menu → Connect live and scan this code. In another browser, open the invitation link below.
Or enter this code:
Waiting for another device. You can keep working while it connects.
Browsers can edit code; every device can use scene controls. The device that started the session controls playback.
Connection settings
A full invitation link includes its host. With a code alone, both devices need the same live host. Pairing setup

Button
Expose a clickable control
The spawned control retains a typed callback for host click dispatch; initialization makes the example's ready state observable.
