[Unity3D]多个摄像机进行场景的切换

摄像机比作人的眼睛最适合不过了。比如：极品飞车里面可变换视觉角度，可以从多个角度观察汽车。

切换摄像机：一个键控制一个摄像机

这里是有多少台摄像机就要设置多少个建,有些场景可能有十多个视角，比如NBA2K游戏里面就有多达12个视角以上，下面这种方法就不适用了，

 using UnityEngine;
 using System.Collections;

 public class ActiveCamera : MonoBehaviour {

     public GameObject camFirst;
     public GameObject camThree;
     public GameObject camSky;

     public float changeInterval = 1.0f;

     public string showStr = "";

     void Start () {
         FindCamera();
     }

     //找到摄像机对象
     void FindCamera()
     {
         camFirst = GameObject.Find("Main Camera");//第一人称视角
         camThree = GameObject.Find("CameraThree");//第三人称视角
         camSky = GameObject.Find("CameraSky");//空中俯瞰视角

         camFirst.active = true;
         camThree.active = false;
         camSky.active = false;

     }
     void Update () {

     }

     void OnGUI()
     {
         ChangeAngle1();
     }
     void ChangeAngle1()
     {
         if (Input.GetKey(KeyCode.Alpha1))
         {
             SetFalse();
             camFirst.active = true;
             showStr = "切换至第三人称视角";
         }
        else if (Input.GetKey(KeyCode.Alpha2))
         {
             SetFalse();
             camSky.active = true;
             showStr = "切换至空中视角";
         }
         else if (Input.GetKey(KeyCode.Alpha3))
         {
             SetFalse();
             camThree.active = true;
             showStr = "切换至第一人称视角";
         }
         Debug.Log(showStr);
        // GUILayout.Button(showStr);
     }

     void SetFalse()
     {
         camFirst.active = false;
         camThree.active = false;
         camSky.active = false;
     }



 }

切换摄像机：一个键控制N个摄像机

下面尝试的代码不起效果，有待解决

 void ChangeAngle2()
    {

        if (Input.GetKey(KeyCode.Z))
        {


            if (camFirst.active)
            {
                camFirst.active = false;
                camThree.active = false;
                camSky.active = true;
                showStr = "切换至第三人称视角";

            }

            if (camThree.active)
            {
                camFirst.active = false;
                camThree.active = false;
                camSky.active = true;
                showStr = "切换至空中视角";

            }

            if (camSky.active)
            {
                camFirst.active = true;
                camThree.active = false;
                camSky.active = false;
                showStr = "切换至第一人称视角";

            }
        }
        Debug.Log(showStr);
        //GUILayout.Button(showStr);
    }
