本文介绍了一个使用Unity实现的CoverFlow效果示例代码，该脚本通过加载指定数量的图片并创建平面对象来展示CoverFlow效果。此外，还实现了鼠标拖动时图片的平滑移动与旋转功能。

using UnityEngine;
using System.Collections;

public class CoverFlow  : MonoBehaviour {

	public int numberOfPhotos = 4;
	public ArrayList PhotoObjects = new ArrayList();
	private Vector2 first = Vector2.zero;
	private Vector2 second = Vector2.zero;
  
	void Start(){
	  LoadImages();
  	}
  
	void LoadImages()
	{
		for(int nLoop = 0; nLoop < numberOfPhotos; nLoop++)
		{
			GameObject PhotoObject = GameObject.CreatePrimitive(PrimitiveType.Plane);
			
			PhotoObjects.Add(PhotoObject);
			
			PhotoObject.transform.position = new Vector3(8 + (nLoop - numberOfPhotos / 2) * 8.2f, 0.5f, 0);
			
			PhotoObject.transform.eulerAngles = new Vector3(-270, (nLoop - numberOfPhotos / 2) * -45, 0);
			
			PhotoObject.renderer.material.mainTexture = Resources.Load("photo" + nLoop) as Texture2D;
		}
	}
  
	void MoveObject(int dir) 
	{
		for(int nLoop = 0; nLoop < numberOfPhotos; nLoop++)
		{
			GameObject PhotoObject = PhotoObjects[nLoop] as GameObject;
			Vector3 movePoint = PhotoObject.transform.position;
			Vector3 eulerPoint = PhotoObject.transform.eulerAngles;
			movePoint.x += dir * 0.2f;
			eulerPoint.y += dir * 2f;
			PhotoObject.transform.position = movePoint;
			PhotoObject.transform.eulerAngles = eulerPoint;
		}
	
	}
  
	void OnGUI()
	{
		
		if(Event.current.type == EventType.MouseDown)
		{
			first = Event.current.mousePosition;
		}
		
		if(Event.current.type == EventType.MouseDrag)
		{
			second = Event.current.mousePosition;
		}
		
		if(second.x < first.x)
		{
			print ("Left");
			MoveObject(-1);
		}
		else if(second.x > first.x)
		{
			print ("Right");
			MoveObject(1);
		}
		
		first = second;
	}
}
