Modify a simple Ruby program to move a shape across the screen by modifying the tasks in the Gosu cycle update$()$ and draw$()$ methods.

Enhance the code provided as follows:

$$ Add a variable in the initialize$()$ method called shape$\_$x with the initial value of zero.

$$ Add code into the update$()$ method that will add $10$ to shape$\_$x$.$

$$ Add code into the draw$()$ method that will draw a shape $($square or circle of any visible colour$)$ at the y coordinate of $30$ and x coordinate of shape$\_$x$.$ Regular main$()$ compared with GOSU cycle

The GOSU cycle can also be represented as:

require 'gosu'

module ZOrder

BACKGROUND, MIDDLE, TOP $=*0.\mathrm{.}2$

end

class GameWindow $$ Gosu::Window

def initialize

super$(200,135,$ false$)$

self.caption $=$ "Gosu Cycle Example"

@background$\_$image $=$ Gosu::Image.new$("$media$/$earth$.$png$")$

@font $=$ Gosu::Font.new$(20)$

@cycle $=0$

@shape$\_$x $=0$

end

def update

@cycle $+=1$

@shape$\_$x $+=10$

end

def draw

@background$\_$image.draw$(0,0,$ ZOrder::BACKGROUND$)$

@font.draw$\_$text$("$Cycle count: #$\{$@cycle$\}",10,10,$ ZOrder::TOP, $1\mathrm{.}0,1\mathrm{.}0,$ Gosu::Color::BLACK$)$

# Draw a shape $($in this case, a square$)$ at the specified coordinates

Gosu.draw$\_$rect$($@shape$\_$x$,30,50,50,$ Gosu::Color::GREEN, ZOrder::TOP$)$

end

end

window $=$ GameWindow.new

window.show
