unity之让obj旋转自转等操作

1.让cube沿着矩形四个点运动

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

public class cube : MonoBehaviour {

    // Use this for initialization
    private Vector3 vec;
    float time = ;
    void Start () {
        vec = transform.position;//存取坐标
    }
    int speed = ;
    float speed2 = ;
   // bool b = true;
    // Update is called once per frame
    void Update () {
        //time += Time.deltaTime;//计时器
                               //移动

        transform.localScale = new Vector3(,,);
        transform.Translate(new Vector3(0.02f * speed, , speed2));
        if (transform.position.x >=)
        {
            speed = ;
            speed2 = -0.02f;
        }
        if (transform.position.z<- )
        {
            speed = -;
            speed2 = ;

            }
        if (transform.position.x < -)
        {
            speed = ;
            speed2 = 0.02f;
        }
        if (transform.position.z >)
        {
            transform.position = vec;
            speed = ;
            speed2 = ;
        }

        //transform.Rotate(0, speed, 0);
    }
}

2.cube之按键操作

//transform.Rotate(Vector3.right,50,Space.World);
        自转// transform.RotateAround(Vector3.right,5);//只有世界坐标下的运动
        transform.RotateAround(Vector3.zero,Vector3.up,);//围绕别人转
        //if (Input.GetKey("w"))
        //{s
        //    transform.Translate(Vector3.forward);//局地坐标（相对坐标）(0,0,1)
        //}
        //if (Input.GetKey("s"))
        //{
        //    transform.Translate(Vector3.back);//世界坐标，绝对坐标(0,0,-1)
        //}
        //if (Input.GetKey("a"))
        //{
        //    transform.Rotate(Vector3.down);//(0,-1,0)
        //}
        //if (Input.GetKey("d"))
        //{
        //    transform.Rotate(Vector3.up);//(0,1,0)
        //}
       // transform.Translate(Vector3.right);//(1,0,0)
       // transform.Translate(Vector3.left);//(-1,0,0)

        //if (Input.GetKey(KeyCode.W))
        //{
        //    Debug.Log("摁下了W键");
        //}
        //if (Input.GetKeyDown(KeyCode.W))
        //{
        //    Debug.Log("Down了一下");
        //}
        //if (Input.GetKeyUp(KeyCode.W))
        //{
        //    Debug.Log("Up了一下");
        //}
        //if (Input.GetKey(KeyCode.Space))
        //{
        //    Debug.Log("摁下了空格键");
        //}
        //if (Input.GetKeyDown(KeyCode.Space))
        //{
        //    Debug.Log("Down了一下");
        //}
        //if (Input.GetKeyUp(KeyCode.Space))
        //{
        //    Debug.Log("Up了一下");
        //}
        //if (Input.GetMouseButton(0))
        //{
        //    print("持续摁下了鼠标左键");
        //}
        //if (Input.GetMouseButtonDown(0))
        //{
        //    print("摁下了鼠标左键");
        //}
        //if (Input.GetMouseButtonUp(0))
        //{
        //    print("抬起了鼠标左键");
        //}
        //if (Input.GetMouseButton(1))
        //{
        //    print("摁下了鼠标右键");
        //}
        //if (Input.GetMouseButton(2))
        //{
        //    print("摁下了鼠标中键");
        //}

3.射线检测

Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
        RaycastHit hit;//检测信息
        if (Physics.Raycast(ray,out hit))
        {
            print(hit.point);
            if (hit.collider.name == "Cube")
            {
                hit.collider.gameObject.GetComponent<MeshRenderer>().material.color = Color.red;
            }

        }

4.cube岁鼠标移动

public GameObject obj;
    Vector3 pos;
    bool b = false;
    // Use this for initialization
    void Start () {

    }

    // Update is called once per frame
    void Update ()
    {
       // transform.LookAt(obj.transform);
        Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
        RaycastHit hit;//检测信息
        if (Physics.Raycast(ray, out hit))
        {
            if (Input.GetMouseButtonDown())
            {
                pos = hit.point;
                transform.LookAt(new Vector3(pos.x, pos.y + 0.5f, pos.z));//lookat
                b = true;
            }
        }
        if (b)
        {
            transform.Translate(,,*Time.deltaTime);
            if (Vector3.Distance(transform.position,pos)<1f)
            {
                b = false;
                print();
            }
        }
    }

点击cube随机变颜色，掉下去
     using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class RayDiao : MonoBehaviour {
    GameObject obj;
    // Use this for initialization
    void Start () {

    }
    Color[] gameclor = { Color.black, Color.blue, Color.cyan, Color.green, Color.red, Color.yellow };//定义颜色数组
    //Random num = new Random();
    // Update is called once per frame
    void Update () {
        Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
        RaycastHit hit;//检查信息
        if (Physics.Raycast(ray,out hit))
            {
            if (Input.GetMouseButtonDown())//判断是否点击了鼠标左键
            {

            if (hit.collider.tag.Equals("cube"))//判断是否点击的是cube
            {
hit.collider.gameObject.GetComponent<MeshRenderer>().material.color = gameclor[Random.Range(, gameclor.Length)];//随机添加颜色

                    //hit.collider.gameObject.GetComponent<Rigidbody>().useGravity = true;//使添加的刚体激活
                    hit.collider.gameObject.AddComponent<Rigidbody>();//增加刚体
                  // obj= hit.collider.gameObject;

            }
            }
        }
        //if (obj != null)//不是空
        //{
        //    obj.transform.Translate(0, -1*Time.deltaTime, 0);//以（-1*Time.deltaTime）的速度下降
        //}

    }
}

添加cube的方法，如消消乐
    using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class creatCube : MonoBehaviour {
    //public GameObject cube;
    // Use this for initialization

    Color [] c = { Color.black, Color.blue, Color.clear, Color.cyan, Color.green, Color.red, Color.yellow };
    void Start () {
       /* GameObject obj = Instantiate(Resources.Load("Cube")) as GameObject;*///另一种生成cube方法

        //GameObject obj = Instantiate(cube);//第二种方式生成cube，需要预制体
        //GameObject obj = GameObject.CreatePrimitive(PrimitiveType.Cube);//生成cube
     //   obj.transform.position = Vector3.one;//one表示坐标（1，1，1）
     //obj.transform.rotation = Quaternion.Euler(0, 45, 0);//角度设置
     // obj.transform.localScale = new Vector3(2, 2, 2);//大小设置
        //int index =obj.name.IndexOf("(");//字符串截取
        //obj.name=obj.name.Substring(0, index);

    for (int i = ; i<; i++)
            {
            for (int j = ; j < ; j++)
            {
                GameObject obj = GameObject.CreatePrimitive(PrimitiveType.Cube);//生成cube
                obj.transform.position = new Vector3(i, j, );//生成位置
                obj.transform.localScale = new Vector3(0.9f, 0.9f, 0.9f);//生成大小
                obj.GetComponent<MeshRenderer>().material.color = c[Random.Range(, c.Length)];//随机颜色
            }
            }
    }
    // Update is called once per frame
    void Update () {

    }
}

鼠标点击变大
  Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
        RaycastHit hit;
        if (Physics.Raycast(ray, out hit))
        {
            if (hit.collider.gameObject.tag == "cube" &&Input.GetMouseButtonDown())
            {
                 cubeObj=  hit.collider.gameObject;
                cubeObj.transform.localScale = new Vector3(,,);
            }
        }
        if (Input.GetMouseButtonUp()&&cubeObj)
        {
            cubeObj.transform.localScale = new Vector3(0.9f, 0.9f, 0.9f);
        }
