提供对显示器/屏幕的访问，以便进行渲染操作。
Unity supports multi-display rendering on:
Desktop platforms (Windows, macOS X, and Linux)
Android (OpenGL ES and Vulkan)
iOS
Some features in the Display class only work on some of the supported platforms. See the properties and methods for more information about platform compatibility.
使用 Display 类可在显示器本身上进行操作，使用 Camera.targetDisplay 可设置摄像机，以便分别渲染到各显示器。
另请参阅：Camera.targetDisplay、Canvas.targetDisplay。
using UnityEngine;
public class Example : MonoBehaviour { Camera extCam; Camera cam;
void Start() { // GUI is rendered with last camera. // As we want it to end up in the main screen, make sure main camera is the last one drawn. extCam.depth = cam.depth - 1;
cam.SetTargetBuffers(Display.main.colorBuffer, Display.main.depthBuffer); extCam.enabled = false; }
void Update() { if (Display.displays.Length > 1 && !extCam.enabled) { Display.displays[1].SetRenderingResolution(256, 256); extCam.SetTargetBuffers(Display.displays[1].colorBuffer, Display.displays[1].depthBuffer); } extCam.enabled = Display.displays.Length > 1; } }
