Calling LoadLevelAsync like TheDarkVoid suggested will start the loading process. You could put it in a coroutine so other parts of the game can keep running. It returns an AsyncOperation. You can check ‘isDone’ to see if it’s done, or ‘progress’ to get the progress (0-1). Note that progress doesn’t work well in the editor, but is more accurate in builds.

Then you need to display the progress. Using Unity GUI, you can draw two textures: one for the empty bar background, and one for the filled progress.

public Texture2D emptyProgressBar; // Set this in inspector.
public Texture2D fullProgressBar; // Set this in inspector.

private AsyncOperation async = null; // When assigned, load is in progress.

private IEnumerator LoadALevel(string levelName) {
    async = Application.LoadLevelAsync(levelName);
    yield return async;
}

void OnGUI() {
    if (async != null) {
        GUI.DrawTexture(Rect(0, 0, 100, 50), emptyProgressBar);
        GUI.DrawTexture(Rect(0, 0, 100 * async.progress, 50), fullProgressBar);
    }
}

• Note 1: Untested code; may contain syntax errors.
• Note 2: The example code draws the progress bar at (0,0)-(100,50). Change this to wherever you want to put the bar.

Take a look at LoadLevelAsync, it allows you to load a level and still have other stuff going on like a loading screen. It requires unity pro though, as far as i’m aware there’s no way to archive this without pro.
