XrControllerComponents

Interface XrControllerComponents

Decoded xr-standard controller state for one input source. Every field is nullable because a given device may not expose that button/axis pair; callers should null-check before reading. Index conventions follow the WebXR xr-standard gamepad mapping.

interface XrControllerComponents {
    buttonA: XrButtonState | null;
    buttonB: XrButtonState | null;
    handedness: XrHandedness;
    squeeze: XrButtonState | null;
    thumbstick: XrButtonState | null;
    thumbstickAxes: readonly [number, number] | null;
    touchpad: XrButtonState | null;
    touchpadAxes: readonly [number, number] | null;
    trigger: XrButtonState | null;
}
