一、前言
来看一下怎么截图的吧
二、效果
网络异常，图片无法展示
|
三、代码
using UnityEngine; public class Screenshot : MonoBehaviour { //截图相机 Camera capCamera; //保存图片 Texture2D screenShot; void Start() { capCamera = GameObject.Find("Main Camera").GetComponent<Camera>(); } void OnGUI() { if (GUILayout.Button("Show")) { CaptureCamera(); } } void CaptureCamera() { Rect rect = new Rect(Screen.width * 0f, Screen.height * 0f, Screen.width * 1f, Screen.height * 1f); // 创建一个RenderTexture对象 RenderTexture rt = new RenderTexture((int)rect.width, (int)rect.height, 0); // 临时设置相关相机的targetTexture为rt, 并手动渲染相关相机 capCamera.targetTexture = rt; capCamera.Render(); // 激活这个rt, 并从中中读取像素。 RenderTexture.active = rt; screenShot = new Texture2D((int)rect.width, (int)rect.height, TextureFormat.RGB24, false); //从RenderTexture.active中读取像素 screenShot.ReadPixels(rect, 0, 0); screenShot.Apply(); // 重置相关参数，以使用camera继续在屏幕上显示 capCamera.targetTexture = null; //避免重复添加的错误 RenderTexture.active = null; //销毁这个对象 Destroy(rt); //保存图片 byte[] bytes = screenShot.EncodeToPNG(); string filename = Application.streamingAssetsPath + "/2.png"; System.IO.File.WriteAllBytes(filename, bytes); } }
