Public Methods

Method	Description
Dispose ( ) : void	Unloads the level content.
Draw ( GameTime gameTime, Frame frame, DefaultMaterialSet materials ) : void	Draw everything in the level from background to foreground.
GetBounds ( int x, int y ) : Rectangle	Gets the bounding rectangle of a tile in world space.
GetCollision ( int x, int y ) : TileCollision	Gets the collision mode of the tile at a particular location. This method handles tiles outside of the levels boundries by making it impossible to escape past the left or right edges, but allowing things to jump beyond the top of the level and fall off the bottom.
Level ( IServiceProvider serviceProvider, string path ) : System	Constructs a new level.
StartNewLife ( ) : void	Restores the player to the starting point to try the level again.
Update ( GameTime gameTime ) : void	Updates all objects in the world, performs collision between them, and handles the time limit with scoring.

Private Methods

Method	Description
DrawTiles ( BitmapBatch batch ) : void	Draws each tile in the level.
LoadEnemyTile ( int x, int y, string spriteSet ) : Tile	Instantiates an enemy and puts him in the level.
LoadExitTile ( int x, int y ) : Tile	Remembers the location of the level's exit.
LoadGemTile ( int x, int y ) : Tile	Instantiates a gem and puts it in the level.
LoadStartTile ( int x, int y ) : Tile	Instantiates a player, puts him in the level, and remembers where to put him when he is resurrected.
LoadTile ( char tileType, int x, int y ) : Tile	Loads an individual tile's appearance and behavior.
LoadTile ( string name, TileCollision collision ) : Tile	Creates a new tile. The other tile loading methods typically chain to this method after performing their special logic.
LoadTiles ( string path ) : void	Iterates over every tile in the structure file and loads its appearance and behavior. This method also validates that the file is well-formed with a player start point, exit, etc.
LoadVarietyTile ( string baseName, int variationCount, TileCollision collision ) : Tile	Loads a tile with a random appearance.
OnExitReached ( ) : void	Called when the player reaches the level's exit.
OnGemCollected ( Gem gem, Player collectedBy ) : void	Called when a gem is collected.
OnPlayerKilled ( Enemy killedBy ) : void	Called when the player is killed.
UpdateEnemies ( GameTime gameTime ) : void	Animates each enemy and allow them to kill the player.
UpdateGems ( GameTime gameTime ) : void	Animates each gem and checks to allows the player to collect them.
