public static Camera main ;

Description

第一个启用的摄像机标记为“MainCamera”。(只读)

The primary Camera in the Scene. Returns null if there is no such camera in the Scene. This property uses FindGameObjectsWithTag internally and doesn't cache the result. It is advised to cache the return value of Camera.main if it is used multiple times per frame.

//Place this script on a GameObject to switch between the main Camera and your own second Camera on the press of the "L" key
//Place a second Camera in your Scene and assign it as the "Camera Two" in the Inspector.

using UnityEngine;

public class Example : MonoBehaviour { //This is Main Camera in the Scene Camera m_MainCamera; //This is the second Camera and is assigned in inspector public Camera m_CameraTwo;

void Start() { //This gets the Main Camera from the Scene m_MainCamera = Camera.main; //This enables Main Camera m_MainCamera.enabled = true; //Use this to disable secondary Camera m_CameraTwo.enabled = false; }

void Update() { //Press the L Button to switch cameras if (Input.GetKeyDown(KeyCode.L)) { //Check that the Main Camera is enabled in the Scene, then switch to the other Camera on a key press if (m_MainCamera.enabled) { //Enable the second Camera m_CameraTwo.enabled = true;

//The Main first Camera is disabled m_MainCamera.enabled = false; } //Otherwise, if the Main Camera is not enabled, switch back to the Main Camera on a key press else if (!m_MainCamera.enabled) { //Disable the second camera m_CameraTwo.enabled = false;

//Enable the Main Camera m_MainCamera.enabled = true; } } } }
