# Sandbox.LoadingScreen.LoadFraction

```csharp
static System.Nullable<double> LoadFraction { get; set; }
```

How far the whole game load is, 0 to 1, across all its stages - for a bar that keeps moving once the
downloads are done. 1 once it's made it into the game, so the screen can finish its bar on the way out; null
when no game is loading and the last one didn't make it, or a new screen's up before its load has begun.

Declared in [Sandbox.LoadingScreen](/api/Sandbox.LoadingScreen).
Assembly: `Sandbox.Engine`.
