how to add a mouse pointer to your gosu window

I think the current version of the gosu framework doesn’t have an option to show the mouse pointer. At least, I haven’t found one ( and when I asked on gosu’s wiki, Julian said it was on the todo list ). So, I thought about drawing a mouse pointer. The only thing you’d want to be careful about is that when you draw a mouse pointer in your game ( or whatever you’re using gosu for ) is to make sure that the pointer image is the last one you’re drawing. Seems logic, right ? We’re doing this because the mouse pointer should always the top-most image.

Here’s a screenshot of how it looks like :

And the code behind it :

require "gosu"

class GameWindow < Gosu::Window
	
	def initialize
		super(640,480,false)
		self.caption = "Gosu Window"
		@pointer = Gosu::Image.new(self,"pointer.png",true) # we're loading a picture of the mouse
		@px = @py = 0
	end
	
	def update
		@px = mouse_x # this method returns the x coordinate of the mouse
		@py = mouse_y # this method returns the y coordinate of the mouse
	end
	
	def draw
		@pointer.draw(@px,@py,0) # we're drawing the mouse at the current position
	end
	
end

if __FILE__ == $0
	a = GameWindow.new
	a.show
end
