[Unity3d]虚拟3D汽车展示项目

今天完善成了虚拟3D汽车展示项目的部分功能，虽然用的汽车模型有点粗糙，但感觉还不错，下面我就贴下源码供初学者学习！

项目展示地址：http://114.92.242.208/aspnet_client/system_web/carshow/dxw2.html，说明：浏览器必须要安装unityplayer插件。

项目操作说明： 1.鼠标左击可以点击左右车门，控制它的开关，还可以点击前后盖控制打开和关闭。 2.鼠标滚轮可以缩放，达到一个远近的效果。 3.按住键盘s键可以显示menu，h键可以隐藏menu菜单。

private bool openDoor = false;

private bool closeDoor = false;

private int target = 0;

int flag = 0;

Ray ray;

RaycastHit hitobj;

private GameObject doorl; //左门

// Use this for initialization

 void Start () {

 doorl = GameObject.Find("doorL");//左门

 // Update is called once per frame

 void Update () {

 //画出射线

 ray = Camera.main.ScreenPointToRay(Input.mousePosition);

 if (Input.GetMouseButtonDown(0))

 //鼠标点击车门

 if (Physics.Raycast(ray,out hitobj,1000))

 print("ddd");

 Debug.DrawLine(ray.origin, hitobj.point);

 //左车门

 if (hitobj.collider.name == "doorL")

 print("111");

 if (flag == 0)

 openDoor = true;

 closeDoor = false;

 else

 closeDoor = true;

 openDoor = false;

 flag++;

 flag %= 2;

 //开左门

 if (openDoor)

 //开门

 if (target 40 !isOpenDoor)

 doorl.transform.Rotate(Vector3.forward, 1);

 target = target + 1;

 else

 isOpenDoor = true;

 if(closeDoor)

 //关门

 if (isOpenDoor target 0)

 doorl.transform.Rotate(-Vector3.forward, 1);

 target -= 1;

 else

 isOpenDoor = false;

}

鸿蒙开发实例｜构建轻量级智能穿戴设备用户界面 HarmonyOS提供了轻量级智能穿戴应用开发，开发者可以在运动手表上开发跨设备协同工作的应用，如从与之匹配的智能手机、平板等各类设备上获取信息，便捷地显示在运动手表上，或通过对运动手表的操作来控制其他设备上的操作任务，为消费者带来更加灵活、智慧的分布式交互体验。 轻量级智能穿戴统一使用JS语言进行开发，这里带领大家体验一番。
基于WebGL无插件虚拟场景漫游关键技术（完整版）ThingJS 如果要构建一个具有交互性和拓展性的沉浸式漫游场景，常用到3DSMAX、three.js等软件技术，学习门槛较高；ThingJS可视化组件更加轻量化，B/S架构下的3D可视化应用构建更轻松，为不少企业客户降低了项目开发成本。
