Unity3D 一个设置方向键移动和空格起跳的脚本：

/// This script moves the character controller forward
/// and sideways based on the arrow keys.
/// It also jumps when pressing space.
/// Make sure to attach a character controller to the same game object.
/// It is recommended that you make only one call to Move or SimpleMove per frame.

var speed : float = 6.0;
var jumpSpeed : float = 8.0;
var gravity : float = 20.0;

private var moveDirection : Vector3 = Vector3.zero;

function Update() {
    var controller : CharacterController = GetComponent(CharacterController);
    if (controller.isGrounded) {
        // We are grounded, so recalculate
        // move direction directly from axes
        moveDirection = Vector3(Input.GetAxis("Horizontal"), 0,
                                Input.GetAxis("Vertical"));
        // 这里获取了键盘的前后左右的移动，但注意，这是相对于自己的。
        moveDirection = transform.TransformDirection(moveDirection);
        // 还有一个TransformPoint。这里是把相对于自己的
        // 坐标转换为相对于世界的坐标。
        moveDirection *= speed;

        if (Input.GetButton ("Jump")) {
            moveDirection.y = jumpSpeed;
        }
    }

    // Apply gravity
    moveDirection.y -= gravity * Time.deltaTime;

    // Move the controller
    controller.Move(moveDirection * Time.deltaTime);
}
