CharacterController.velocity

var velocity : Vector3

Description

The current relative velocity of the Character (see notes).

This allows you to track how fast the character is actually walking for example when he is stuck at a wall this value will be the zero vector.

Note: The velocity returned is simply the difference in distance for the current timestep before and after a call to CharacterController.Move or CharacterController.SimpleMove. The velocity is relative because it won't track movements to the transform that happen outside of the CharacterController (e.g. character parented under another moving Transform, such as a moving vehicle).

JavaScript
function Update () {
var controller : CharacterController = GetComponent(CharacterController);
var horizontalVelocity : Vector3 = controller.velocity;
horizontalVelocity = Vector3(controller.velocity.x, 0, controller.velocity.z);

// The speed on the x-z plane ignoring any speed
var horizontalSpeed : float = horizontalVelocity.magnitude;
// The speed from gravity or jumping
var verticalSpeed : float = controller.velocity.y;
// The overall speed
var overallSpeed : float = controller.velocity.magnitude;
}
