为什么动画运行时间不会变短或变长？

Question

所以我有这个脚本，我试图让一个立方体跳转到某个位置，其中一部分是我希望立方体在向新的Rich Point移动时播放动画，我有以下脚本但由于某些原因，动画不会变短或变长为什么？我做错了什么？

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerMovement : MonoBehaviour {

    public float jumpMaxDistance;
    public float jumpSpeed;
    private float distance;

    private bool firstFrame = false;
    private Vector3 richPoint;
    public GameObject player;
    private Animation jump;

    void Start () {
        richPoint = transform.position;
        jump = player.GetComponent<Animation> ();

    }
    // Update is called once per frame
    void Update (){
        //Moves the player to the next point.
        if (firstFrame == true){
            if (transform.position != richPoint) {
                transform.position = Vector3.MoveTowards(transform.position, richPoint, Time.deltaTime * jumpSpeed);


            }//executes if the left click is pressed.
        }
        if (Input.GetMouseButtonDown (0)) {

            RaycastHit hit;

            //Get Ray from mouse position.
            Ray rayCast = Camera.main.ScreenPointToRay (Input.mousePosition);

            //Raycast and check if any object is hit.
            if (Physics.Raycast (rayCast, out hit, jumpMaxDistance)) 
                {
                //Raycast and check if any object is hit.
                if (hit.collider.CompareTag ("RichPoint"))
                {
                    richPoint = hit.collider.transform.position;
                    //This finds the distance between the player and richPoint.
                    float pBTime;
                    pBTime = distance / jumpSpeed;

                    //This plays the Animation depending on tha distance between transform.position and richPoint.
                    jump ["PlayerJump"].time = pBTime;
                    jump.Play ();

                    firstFrame = true;
                }
            }
        }
    }
}

使用动画状态。这里example。
