pngファイルからテクスチャ作成

Texture2D generateTexture2DFromPngFile(string path)
{
  BinaryReader bin = new BinaryReader(new FileStream(path, FileMode.Open, FileAccess.Read));
  byte[] rb = bin.ReadBytes((int)bin.BaseStream.Length);
  bin.Close();
  int pos = 16, width = 0, height = 0;
  for (int i = 0; i < 4; i++) width = width * 256 + rb[pos++];
  for (int i = 0; i < 4; i++) height = height * 256 + rb[pos++];
  Texture2D texture = new Texture2D(width, height);
  texture.LoadImage(rb);
  return texture;
}

マウスオーバーイベント

void Start ()
{
  // obj = GameObject
  EventTrigger eventTrigger = obj.AddComponent<EventTrigger>();
  EventTriggerType eventType = EventTriggerType.PointerEnter;
  System.Action<PointerEventData> listener = onPointerEnterListener;

  EventTrigger.Entry entry = new EventTrigger.Entry();
  entry.eventID = eventType;
  entry.callback.AddListener(data => listener.Invoke((PointerEventData)data));
  eventTrigger.triggers.Add(entry);
}

void onPointerEnterListener(PointerEventData eventData)
{
  Debug.Log("onPointerEnterListener");
}
