Unity3D学习（三）打飞碟游戏

第三次比较大的实践是打飞碟游戏，这时老师已经介绍了各种动作管理，工厂模式之类的模式，比较方便管理，也方便丰富游戏内容。

这次作业有使用运动学和物理学两种处理方式
这里同样仅贴出游戏效果和代码。

checkCollision.cs

using System.Collections;using System.Collections.Generic;using UnityEngine;using game;namespace game {    public class checkCollision : MonoBehaviour {        public Camera cam;        FirstSceneController sceneController;        // Use this for initialization        void Start () {            cam = Camera.main;            sceneController = Director.getInstance ().currentSceneController as FirstSceneController;        }        // Update is called once per frame        void Update () {            if (Input.GetMouseButtonDown (0)) {                Vector3 mp = Input.mousePosition;                Ray ray = cam.ScreenPointToRay (mp);                RaycastHit hit;                if (Physics.Raycast (ray, out hit)) {                    Debug.Log ("enter hit...");                    Debug.Log (hit.collider.gameObject.tag);//                  Disk disk = hit.collider;//                  sceneController.hitDisk (hit.collider.gameObject);//                  Debug.Log(hit.transform.GetComponent<DiskScript> ().disk);                    Disk disk = hit.transform.GetComponent<DiskScript> ().disk;                    if (hit.collider.tag == "Player") {                        Debug.Log ("hit the disks...");//                      Disk disk = hit.transform.GetComponent<DiskScript> ().disk;                        sceneController.hitDisk (disk);                    }//                  if (hit.collider.tag == "Finish") {//                      Debug.Log ("hitting the grond...");//                      sceneController.hitGround (hit.point);//                  }//                  if (hit.collider.tag == "Test") {//                      Debug.Log ("collision test...");//                  }                }            }        }    }}

Director.cs

DiskFactory.cs

DiskScript.cs（这个是为了能从GameObj获取到controller）

using System.Collections;using System.Collections.Generic;using UnityEngine;using game;namespace game {    public class DiskScript : MonoBehaviour {        public Disk disk;        // Use this for initialization        void Start () {            for (int i = 0; i < transform.childCount; i++)            {                GameObject g = transform.GetChild(i).gameObject;                g.AddComponent<DiskScript>().disk = disk;            }        }        // Update is called once per frame        void Update () {        }    }}
