Unity3d 指令碼實現CoverFlow 效果

 

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(){
  
  LoadImage();
 }
 
 void LoadImages()
 {
  for(int nLoop = 0; nLoop < numberOfPhotos; nLoop++)
  {
   GameObject PhotoObject = GameObject.CreatePrimitive(PrimitiveType.Plane);
   
   PhotoObjects.Add(PhotoObject);
   
   PhotoObject.transform.position = Vector3(8 + (nLoop - numberOfPhotos / 2) * 8.2, 0.5, 0);
   
   PhotoObject.transform.eulerAngles = Vector3(-270, (nLoop - numberOfPhotos / 2) * -45, 0);
   
   PhotoObject.renderer.material.mainTexture = Resources.Load("photo" + nLoop);
  }
 }
 
 void MoveObject(int dir)
 {
  for(int nLoop = 0; nLoop < numberOfPhotos; nLoop++)
  {
   GameObject PhotoObject = PhotoObjects[nLoop];
   
   PhotoObject.transform.position.x += dir * 0.2;
   
   PhotoObject.transform.eulerAngles.y += dir * 2;
  }
  
 }
 
 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;
 }
}

 

隨便弄幾張圖放到Assets/Resources目錄下，取名叫photo0, photo1.........
