切换摄像头实现视角切换

按 Z、X键不同顺序      实现4个摄像头循环切换 

SetActive

1.创建4个camera

2.创建一个空物体 ，挂上cameraSwitch脚本

3.camera拖到脚本上

public class cemareSwitch : MonoBehaviour
{
	public GameObject[] cameras;
	public bool changeAudioListener = true;

	private void Start()//初始视角
    {
		cameras[0].SetActive (true);
		cameras[1].SetActive(false);
		cameras[2].SetActive(false);
		cameras[3].SetActive(false);
	}
	public int i = 0;//调试用
    void Update()
	{
		
		if (Input.GetKeyDown(KeyCode.Z))
		{
			i = i + 1;
			i = i % 4;
			SwitchCamera(i);
		}

        if (Input.GetKeyDown(KeyCode.X))
        {
			i = i - 1;
			i = (i+4) % 4;
			SwitchCamera(i);
		}
	}

	void SwitchCamera(int index)//切换
	{

		int k = 0;
		for (k = 0; k < cameras.Length; k++)
        {
			if (k == index)
			{
				cameras[k].SetActive(true);
			}

			if(k!=index)
            {
				cameras[k].SetActive(false);
			}


        }
			
			
			
		
		


	}
