The linearVelocity read-only property of the GamepadPose interface returns an array representing the linear velocity vector of the Gamepad, in meters per second.

In other words, the current velocity at which the sensor is moving along the x, y, and z axes.


var myGamepadLinVel = gamepadPoseInstance.linearVelocity;


A Float32Array, or null if the gamepad is not able to provide linear velocity data.
