Get current value in a for loop

Questions & Answers
1

I want to create a loading screen when data is processing in a for loop.

an example:

 void Start()
 {
    double currentData;
    double endData = 50 * 50 * 50;

    for(int i = 0; i < 50; i++)
    {
      for(int e = 0; e < 50; e++)
      {
        for(int a = 0; a < 50; a++)
        {
          currentData = a * e * i;
        }
      }  
    }
 }
void OnGUI()
{
    GUI.Label(new Rect((Screen.width - 200)/2, (Screen.height - 50)/2, 200, 50), "Loading blocks: " + 100/endData * currentData + "%");
}

Unfortunately this doesn’t work, any suggestions?

Don’t loop through things in one method? It’s going to go through that entire loop before it even touches OnGUI. You should use a coroutine or do this over the course of multiple frames via the update method, if you want it to share processing time with your loading graphics.

Try something like this:

void Start()
{
    double currentData;
    double endData = 50 * 50 * 50;
    StartCoroutine("LoadData");
}

void OnGUI()
{
     GUI.Label(new Rect((Screen.width - 200)/2, (Screen.height - 50)/2, 200, 50), "Loading blocks: " + 100/endData * currentData + "%");
}

IEnumerator LoadData()
{
    for(int i = 0; i < 50; i++)
    {
      for(int e = 0; e < 50; e++)
      {
        for(int a = 0; a < 50; a++)
        {
          currentData = a * e * i;
          yield return null;
        }
      }  
    }
    StopCoroutine("LoadData");
}
