Cube 逐点运动到点停止

首先生成如图的Cube物体；

Cube物体从原始位置(6.011，2.54，0)开始，运动到(0,0，0)位置后，转向位置(-3, 2, 0),最后转向(4, 4, 0)位置停止运动。

新建一个名为PtoPMove的C#脚步;

using UnityEngine;
using System.Collections;


public class PtoPMove : MonoBehaviour {
public GameObject moveCube;
public Vector3[]pArr;
public int len;
private float speed=3.0f;
private float s;    //当前要移动的距离
private float dis;
private int pIndex = 0;
private float speedX;
private float speedY;
private int moveFlag;


// Use this for initialization
void Start () {
pArr = new Vector3[3];
pArr [0] = new Vector3 (0, 0, 0);
pArr [1] = new Vector3 (-3, 2, 0);
pArr [2] = new Vector3 (4, 4, 0);
len = pArr.Length;


moveCount ();
}
void moveCount(){
Vector3 p = pArr [pIndex];
Vector3 v = moveCube.transform.position;  //重要：v此时是时刻在变得三维坐标，而不是固定的第一个点的位置；
float dx = p.x - v.x;
float dy = p.y - v.y;
s = Mathf.Sqrt (dx * dx + dy * dy);
float hudu = Mathf.Atan2 (dy, dx);
speedX = speed * Mathf.Cos (hudu);
speedY = speed * Mathf.Sin (hudu);
moveFlag = 1;
dis = 0;


}
// Update is called once per frame
void Update () {
if (moveFlag == 1) {
moveCube.transform.Translate(Vector3.right*Time.deltaTime*speedX);
moveCube.transform.Translate(Vector3.up*Time.deltaTime*speedY);
dis += Time.deltaTime*speed;
if(dis>=s){
Debug.Log (moveCube.transform.position);
pIndex++;
//moveCube.transform.position = p;
if(pIndex<len){
moveCount();
}else{
moveFlag=0;
}
}
}
}
}
