Unity3D 实现原始方式获取连拍照片

        今天为大家分享一下，如何在unity利用原始方式实现获取连拍照片，甚至我们可以把一系列图片的利用一些视频软件后期合成视频。
    但是直接在用代码利用这一系列图片合成视频，这种方式还是不推荐的，毕竟效率很低下，如果需要实现录屏功能，ShareREC便是一个比较好的选择。
   
     好吧！废话不多讲，我们直接进入主题噢！
    1.新建一个unity项目，并且在项目中新建Editor文件夹，首先我们先实现一个编辑器，在文件夹下有一个CapResRecorder_Editor.cs;
      代码如下：

using UnityEngine;
using System.Collections;
using UnityEditor;

public class CapResRecorder_Editor  {

	[MenuItem("GameObject/Create CapResRecorder", false,10)]
	public static void CreateHiResRecorder(MenuCommand menuCommand) {

		CapResRecorder recorder = Object.FindObjectOfType();
		if (recorder) {
			Debug.LogWarning("An instance of CapResRecorder already exists!");
			Selection.activeObject = recorder.gameObject;
		} else {
			
			GameObject go = new GameObject("CapResRecorder");
			go.AddComponent();
			GameObjectUtility.SetParentAndAlign(go, menuCommand.context as GameObject);
			Undo.RegisterCreatedObjectUndo(go, "Create " + go.name);
			Selection.activeObject = go;
		
		}
	}

}

    2.这一步稍微比较重要，正是生成系列图片的逻辑代码类CapResRecorder.cs;
       
      代码如下：

using UnityEngine;
using System.Collections;
using System.IO;


public class CapResRecorder : MonoBehaviour {
	
	public KeyCode key = KeyCode.A;
	public int frameRate = 30;
	
	bool isCapturing = false;
	string prefix,path;
	int folderIndex = 0;
	int imgIndex = 0;
	float localDeltaTime,prevTime,fixedDeltaTimeCache;
	
	void Start () {
		DontDestroyOnLoad(this.gameObject);
		fixedDeltaTimeCache = Time.fixedDeltaTime;

		if (Application.isEditor)
			prefix = Application.dataPath+"/../CapResRecorder/";
		else 
			prefix = Application.dataPath+"/CapResRecorder/";
		Debug.Log("IMG sequence will be saved to "+prefix);
	}
	
	
	void LateUpdate () {
		
		localDeltaTime = Time.realtimeSinceStartup - prevTime;
		prevTime = Time.realtimeSinceStartup;
		
		if (Input.GetKeyDown(key)) {
			isCapturing = !isCapturing;
			if (isCapturing) {
				folderIndex+=1;
				imgIndex = 0;
				path = prefix+"IMG Sequence "+folderIndex;
				if (Directory.Exists(path)==false) 
					Directory.CreateDirectory(path);
				path = path + "/";
				
			} else {
				Time.timeScale = 1f;
				//Time.fixedDeltaTime = fixedDeltaTimeCache;
			}
		}
		if (isCapturing){
			Application.CaptureScreenshot(path+imgIndex.ToString("D8")+".png");
			imgIndex+=1;
			Time.timeScale = 1.0f/localDeltaTime/frameRate;
			//Time.fixedDeltaTime = fixedDeltaTimeCache / Time.timeScale;
		}
	}
}

    3.然后我们发现在GameObject下面有一个选项，我们可以直接点击创建一个CapResRecorder对象;

    4.最后我们直接运行项目，就得到一系列的截图啦！
