直接上码：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class ppp : MonoBehaviour {
public int capx = 0;
public int capy = 0;
public int capwidth = 700;
public int capheight = 500;
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
if (Input.GetKeyDown(KeyCode.A)) {
//自定义截屏
StartCoroutine (getScreenTexture());
//unity 自带截屏，只能是截全屏
Application.CaptureScreenshot ("shot.png");
}
}
IEnumerator getScreenTexture() {
yield return new WaitForEndOfFrame ();
//需要正确设置好图片保存格式
Texture2D t = new Texture2D (capwidth,capheight,TextureFormat.RGB24, true);
//按照设定区域读取像素；注意是以左下角为原点读取
t.ReadPixels (new Rect(capx, capy, capwidth, capheight), 0, 0, false);
t.Apply ();
//二进制转换
byte[] byt = t.EncodeToPNG ();
System.IO.File.WriteAllBytes (Application.dataPath + Time.time + ".png", byt);
}
}
