Application.LoadLevel
static function LoadLevel(index: int): void;
static function LoadLevel(name: string): void;
Parameters

index The level to load.
name The name of the level to load.
Description

Loads the level by its name or index.

Before you can load a level you have to add it to the list of levels used in the game. Use File->Build Settings... in Unity and add the levels you need to the level list there. MonoBehaviour.OnLevelWasLoaded is called on all active game objects after the level has been loaded.
	// Load the level named "HighScore".

Application.LoadLevel ("HighScore");
When loading a new level all game objects that have been loaded before are destroyed. If you want to let an object survive when loading a new level, use Object.DontDestroyOnLoad. Calling LoadLevel will update Application.loadedLevel and Application.loadedLevelName. See Also: Application.LoadLevelAsync, Application.LoadLevelAdditive, Application.LoadLevelAdditiveAsync.
