[Scripting Question] input mouse and keyboard

[gioni]

What's wrong with this script because if I press the right button on the panel nothing happens

class TestScene
	def start
		@viewport=Viewport.new(0,0,Graphics.width,Graphics.height)
		@viewport.z=99999
		@sprites={}
		
		@sprites["bg"]=IconSprite.new(0,0,@viewport)    
		@sprites["bg"].setBitmap("Graphics/Pictures/Menu/background")
		
		@sprites["panel_1"]=IconSprite.new(0,0,@viewport)    
		@sprites["panel_1"].setBitmap("Graphics/Pictures/Menu/panel")
		@sprites["panel_1"].x = 3
		@sprites["panel_1"].y = 47 
		@sprites["panel_1"].y = 47 +200
	end
	
	def update 
		loop do
			Graphics.update 
			Input.update 
			pbUpdateSpriteHash(@sprites) 
			if Input.trigger?(Input::B) || Input.trigger?(Input::C)
				break
			end
		end
	end
	def
		self.update
		self.Input 
	end
	
	def terminate
		pbDisposeSpriteHash(@sprites) 
		@viewport.dispose
		Graphics.update
	end
	
end

Input.update
if $mouse.leftClick?(["panel_1"])
  Graphics.update
  Input.update	
  self.pbMenuClick
  @sprites["panel_1"].visible=false
	pbSEPlay("BW2MenuSelect")
end


class TestSceneCall

	def initialize(scene)
		@scene = scene
	end
	
	
	def start
		@scene.start
		@scene.update
		@scene.terminate
	end
	
end



def aa
	scene=TestScene.new
	screen=TestSceneCall.new(scene)
	screen.start
end
