public static Camera main ;

描述

第一个启用的摄像机标记为“MainCamera”。(只读)

场景中的主摄像机。如果场景中没有主摄像机,则返回 /null/。 该属性在内部使用 FindGameObjectsWithTag,不缓存结果。如果每帧需要多次使用 Camera.main,建议缓存其返回值。

//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; } } } }
