Unity3D基础

鼠标事件：

OnMouseEnter():鼠标进入

OnMouseExit():鼠标移出

OnMouseDown():鼠标点击

OnMouseUp():鼠标抬起

static GameObject Instantiate() 克隆

static void Destroy()

位置 、 材料 、碰撞 、渲染

地形、预制、照相机、碰撞

using UnityEngine;using System.Collections;public class shubiao : MonoBehaviour {    // Use this for initialization    void Start () {        }        // Update is called once per frame    void Update () {        }    //:鼠标进入    void   OnMouseEnter(){        gameObject.renderer.material.color = Color.black;    }            void    OnMouseExit(){        gameObject.renderer.material.color = Color.blue;    }//:鼠标移出                void    OnMouseDown(){        gameObject.renderer.material.color = Color.yellow;    }//:鼠标点击                    void    OnMouseUp()        {        gameObject.renderer.material.color = Color.red;        GameObject.Destroy (gameObject);        }//:鼠标抬起}

GUI布局

using UnityEngine;using System.Collections;public class GIU : MonoBehaviour {    PRivate string str="张三";    private string str2="";    private bool  sex=false;    private string _userName;    // Use this for initialization    void Start () {        }        // Update is called once per frame    void Update () {        }    void OnGUI()    {        /*if (GUI.Button (new Rect (10, 10, 70, 20), "按钮")) {                    print ("A")    ;                }        if (GUI.RepeatButton (new Rect (10, 100, 70, 20), "按钮")) {                print ("B")        ;                }        str=GUI.TextArea (new Rect (10, 20, 100, 20), str);        str2=GUI.PassWordField (new Rect (10, 150, 200, 20), str2, '*');        sex=GUI.Toggle(new Rect(10,100,50,50),sex,"男" );//check*/        GuI.Label(new Rect(10,10,70,20),"用户名");        _userName = GUI.TextArea (new Rect (100, 10, 200, 20), _userName);        _sex = GUI.Toggle (new Rect (10, 70, 50, 20), _sex, "男");        _sex=GUI.Toggle(new Rect(10,140,50,20),!_sex,"女");    }}

GUILayOut 布局

例一：      private string str3="测试用的字符串";  //全局变量   GUILayout.Button ("GUILayout按钮");        if (GUILayout.Button (str3)) {            str3+=str3 ;                }        if (GUI.Button (new Rect (50, 100, 100, 100), str)) {            str3+=str3;                }    

 例二：  GUILayout.BeginHorizontal ();  //水平排列        GUILayout.Button ("我是GUILayoutButton");        GUILayout.Button ("我是GUILayoutButton");        GUILayout.Button ("我是GUILayoutButton");        GUILayout.Button ("我是GUILayoutButton");        GUILayout.EndHorizontal ();        GUILayout.BeginVertical ();  //纵向排列        GUILayout.Button ("我是GUILayoutButton");        GUILayout.Button ("我是GUILayoutButton");        GUILayout.Button ("我是GUILayoutButton");        GUILayout.Button ("我是GUILayoutButton");        GUILayout.EndVertical();         

移动w 键 A键 S键 D键 ：

using UnityEngine;using System.Collections;public class fouth : MonoBehaviour {//右边是 Z 轴，上边是y轴，X轴看不见的状态；    GameObject go;    // Use this for initialization    void Start () {        go=GameObject.Find("Cube3");        go.renderer.material.color = Color.red;    }        // Update is called once per frame    void Update () {        if (Input.GetKey (KeyCode.W)) {            go.transform.Translate(-5*Time.deltaTime,0,0,Space.Self);                }        if (Input.GetKey (KeyCode.S)) {            go.transform.Translate(5*Time.deltaTime,0,0,Space.Self);        }        if (Input.GetKey (KeyCode.A)) {            go.transform.Translate(0,0,-5*Time.deltaTime,Space.Self);        }        if (Input.GetKey (KeyCode.D)) {            go.transform.Translate(0,0,5*Time.deltaTime,Space.Self);        }    }}

旋转：

using UnityEngine;using System.Collections;public class NewBehaviourScript : MonoBehaviour {    // Use this for initialization    void Start () {        }        // Update is called once per frame    void Update () {//旋转        gameObject.transform.Rotate (0, 15 * Time.deltaTime, 0, Space.Self);    }}

碰撞：

void OnCollisionEnter(Collision co)    {        co.gameObject.renderer.material.color = Color.blue;    }

预制（克隆）：

void Update () {        if (Input.GetKeyUp (KeyCode.Space)) {            GameObject.Instantiate(go,gameObject.transform.position,gameObject.transform.rotation);                }    }

void Update () {        if (Input.GetKey (KeyCode.LeftShift)) {                        if (Input.GetKey (KeyCode.LeftShift)) {                                gameObject.animation.Play ("run");                gameObject.transform.transform(Vector3.forward*Time.deltaTime*6); //朝前移动 距离 速度                        } else {                                gameObject.animation.Play ("walk");                gameObject.transform.transform(Vector3.forward*Time.deltaTime*0); //朝前移动 距离 速度                        }                        }        else {            gameObject.animation.Play("stand");            gameObject.transform.transform(Vector3.forward*Time.deltaTime*3); //朝前移动 距离 速度                }         }

阴影烘焙：对灯设置 有阴影，对要烘焙的设置静止，打开 windows 点 light烘焙 back ；

动画剪辑：暂无

c#控制动画：

application

切换场景

  if (Input.GetKeyDown (KeyCode.A)) {            Application.LoadLevel(0);                }

截屏

if (Input.GetKeyDown (KeyCode.Space)) {            Application.CaptureScreenshot(@"c:/1.png")                }

打开一个网址

Application.OpenURL("H");//打开一个网址

退出：

Application.Quit();//退出

左击 游戏对象消失

        if(Input.GetMouseButtonDown(0)) //如果 按到 左击        {            Ray ray=camera.main.ScreenPointToRay(Input.mousePosition);//拿到点击的位置            RaycastHit hitInfo;            if(Physics.Raycast(ray,out hitInfo))//点击到            {                Destroy (hitInfo.collider.gameObject);   //销毁游戏对象            }        }
