class Tile

TILE CLASS. This class represents each of the pictures in the game window. Each tile is created with the initialize function that accepts a Gosu

image for the main picture (img), x- and y-coordinates, an image to display when the tile is face down (img2), and id string, and a completion image that is displayed when the tile is matched (chkImg). The draw function renders the tile to the game window. This class contains various utility functions for tiles.

initialize function of the Tile class: this will create a Tile object with all necessary parameters

Parameters: image name, xLocation, and yLocation. image name is the name of the image that was saved, and the location variables give the Tile's location on the board img2 will be used as the back of the image for when it is face-down idStr is the string that contains the path of the image for the given tile, it will be used for comparisons between tiles

def initialize( img, xL, yL, img2, idS, chkImg )
        @image = img
        @rev = img2
        @xLocation = xL
        @yLocation = yL
        @flipped = false
        @matched = false
        @idStr = idS
        @chkImage = chkImg

draw function of the Tile class: this will draw the image at the Tile's specified location.

if the tile is not fliped and not matched, then its facedown image is drawn. if the tile is flipped and not matched, then its true image is drawn. if the tile is matched, then the completion image is drawn.

# File lib/tumblr-game/tile.rb, line 30
def draw
        if !@flipped and !@matched then
                @rev.draw(@xLocation, @yLocation, 0)
        elsif @flipped and !@matched
                @image.draw(@xLocation, @yLocation, 0)
        else
                @chkImage.draw(@xLocation, @yLocation, 0)
        end
end

# File lib/tumblr-game/tile.rb, line 41
def flip( bool )
        @flipped = bool
end
return_id() click to toggle source

# File lib/tumblr-game/tile.rb, line 46
def return_id
        return @idStr
end

        return @matched
end
