## Function to change mode
You should create a function to change the game mode. We will place a call for this in a moment, but for now, we do something like:

* Clear all sprites: The sprite controller has a process for returning all sprites that are duplicates of named sprites. We can use that to clear all the sprites like:
```c#
void ClearAllSprites()
{
foreach(Sprite one in mySpriteController.SpritesBasedOffAnything())
one.Destroy();
}
```
* Start Game: Change the background to whatever the game background is. Duplicate all the sprites you need for the game and place them in their starting positions.
* Start Menu: Change the background to whatever the menu background image is. Duplicate all the menu sprite buttons and place them in their respective menu spots. (You should have menu buttons for things like “play”, “settings”, “high-scores”, and “exit”)
* Start Settings: This is usually a special “menu” that has items like: “volume”, “speed”, etc.

If(currentmode == GameMode.Playing) {
CheckForKeypresses();
CheckForChangeInLevel();
