# Overview of the DebugOverlay System

The debug overlay system in s&box is very easy to use and fairly useful for debugging purposes, below is a example of how you can draw debug screen text and a sphere using `DebugOverlay.ScreenText()` you can find all other DebugOverlay methods [here](https://sbox.game/dev/api/Sandbox.DebugOverlaySystem)

In this example we'll simply be using the `OnUpdate()` method to call our DebugOverlay ScreenText and OnStart for the Sphere. 

```cs
	protected override void OnStart()
	{
    	// Sphere will disappear after 5 seconds
		DebugOverlay.Sphere(new Sphere(Vector3.Zero, 10f), Color.Green, 5f);
	}

	protected override void OnUpdate()
	{ 
		const string name = "Cool Game!";
		
		DebugOverlay.ScreenText(new Vector2(400, 500), $"This is my {name}");
	}
```

Below is the result of the code snippet in the scene.
