After a user loses in my game, I want to display a game-over screen that has a restart button/restart image that restarts the game when the user clicks on it with his/her mouse.

I don't know how to implement this mouse click functionality in my code.

For my game, I have a Game() class, with the methods, processEvents(), runLogic() and displayFrame(). I run these methods in the while loop of main().

# loop inside of main()
# pygame, display surface - called screen, already initialized
while not gameExit:
    gameExit = game.processEvents()
    game.runLogic()
    game.displayFrame(screen, background)

In the __init__() method of the Game() class, I have an attribute self.gameOver = False. When self.gameOver is becomes True, the runLogic() function does not run, but instead displayFrame() calls a function, gameOver(display) that displays the game-over screen.

def displayFrame(self, display, background):

    if self.gameOver:
        gameOver(display)

    if not self.gameOver:
        display.blit(background, (0, 0))
        self.allsprites.update()
        self.allsprites.draw(display)

    pygame.display.flip()

The gameOver(display) function displays a restart button. 

def gameOver(display):
    # loadImage returns (image, image.get_rect())
    restartImage = utility.loadImage("restart.png")
    display.blit(restartImage[0], (320, 250))

I want to make it such that when the user clicks this restartImage, the game restarts.

I know that I'll have to handle mouseclick in the processEvents() function.

def processEvents(self):
    for event in pygame.event.get():
        if event.type == pygame.MOUSEBUTTONDOWN:
            pos = pygame.mouse.get_pos()
            # need to use collidepointrect function
            # don't know how to implement!
    return False

Ideally, I will have a function isButtonClicked that goes something like this

def isButtonClicked(mousepos, button):
    return button.collidepoint(mousepos)

And in the processEvents function, I just do

if self.isButtonClicked(pos, restartImage[1]):
    # restart the game 
    self.__init__()

HOWEVER, I cannot directly pass in restartImage as it has been created in gameOver(display). So, I'm not sure how to structure my code so that processEvents can handle a mouseclick to the image/button I created in another function.

Any help will be greatly appreciated. Sorry if my explanation is a bit convoluted. I felt it was necessary to explain my code structure, as my question is more about how to logically write my code than what methods to use.

  • don't run `self.__init__()` - create function `reset_data()` which set all values at start and use it in `__init__()` and when you what to restart game. – furas Jan 04 '17 at 01:07
  • `gameOver` is strange - it is executed thousends times in second and you load image thounsends times. Can't you load image only once ? – furas Jan 04 '17 at 01:14
  • maybe you should split class `Game()` into two classes `Game` and `GameOver` with own functions `processEvents`, `runLogic` and `displayFrame` so they have more control on elements in functions - like this http://imgur.com/MT7tZ4s. Or you should replace class in variable `game` to use different `processEvents`, `runLogic` and `displayFrame` when game is over. – furas Jan 04 '17 at 01:23
