Implementing main menu in game loop, Python2 and Pygame

Question

I have a issue with my game at the moment, the game works fine. however when adding my main menu, It doesn't work, it loads it up but when you press play nothing happens (it doesn't go the game it just stays there). I have attached an image of my simple main menu([1]: https://i.stack.imgur.com/YKY9q.jpg) .My code is below thanks:

import pygame, sys, Funk
from tileC import Tile
from object_classes import *
from interaction import interaction
from A_Star import A_Star
import time


pygame.init()
pygame.font.init()
pygame.mixer.init()

pygame.mixer.music.load('audio/zombie_theme.ogg')
pygame.mixer.music.play(-1)

screen = pygame.display.set_mode((704, 448)) # 32, 32

Tile.pre_init(screen)

clock = pygame.time.Clock()
FPS = 30
total_frames = 0
dungeon = pygame.image.load('images/dungeon.jpg')
survivor = Survivor(32 * 2, 32 * 4)
intro = True

# colours

black = (0,0,0)
white = (255,255,255)
red = (200,0,0)
green = (0,200,0)
orange = (255,127,0)
grey = (50,50,50)
bright_red = (255,0,0)
bright_green = (0,255,0)
bright_orange = (255,215,0)


def text_objects(text, font):
    textSurface = font.render(text, True, (white))
    return textSurface, textSurface.get_rect()

def message_display(text):
    largeText = pygame.font.Font('Creepster-Regular.ttf',115)
    TextSurf, TextRect = text_objects(text, largeText)
    TextRect.center = ((704/2),(448/2))
    gameDisplay.blit(TextSurf, TextRect,)

def button(msg,x,y,w,h,ic,ac,action=None):

    mouse = pygame.mouse.get_pos()
    click = pygame.mouse.get_pressed()
    if x+w > mouse[0] > x and y+h > mouse[1] > y:
        pygame.draw.rect(screen, (ac), (x, y, w, h))
        if click[0] == 1 and action != None:
            if action == "start":
                return
            if action == "end":
                pygame.quit()
                sys.exit()

    else:
        pygame.draw.rect(screen, (ic), (x, y, w, h))



    smallText = pygame.font.SysFont("monospace.ttf",20)
    textSurf, textRect = text_objects(msg, smallText)
    textRect.center = ( (x+(w/2)), (y+(h/2)) )
    screen.blit(textSurf, textRect)





def game_intro():

   intro = True

   while intro:
       for event in pygame.event.get():

           if event.type == pygame.QUIT:
               pygame.quit()
               sys.exit()

       screen.fill(grey)
       largeText = pygame.font.SysFont('Creepster-Regular.ttf',45)
       TextSurf, TextRect = text_objects("2D Tile Based Zombie Game",   largeText)
       TextRect.center = ((704/2),(448/2))
       screen.blit(TextSurf, TextRect)

       button("Play",100,300,100,50,green,bright_green,"start")
       button("Controls",300,300,100,50,orange,bright_orange, "how to play")
       button("Quit",500,300,100,50,red,bright_red, "end")


       pygame.display.update()
       clock.tick(15)
       #break





game_intro()

while True:

    screen.blit(dungeon, (0,0) )

    Zombie.spawn(total_frames, FPS)
    Zombie.update(screen, survivor)

    survivor.movement()

    Bullet.super_massive_jumbo_loop(screen)

    A_Star(screen, survivor, total_frames, FPS)
    interaction(screen, survivor)

    survivor.draw(screen)

    Funk.text_to_screen(screen, 'Health: {0}'.format(survivor.health), 0,0)
    Funk.text_to_screen(screen, 'Score: {0}'.format(survivor.score), 0,15)
    Funk.text_to_screen(screen, 'FPS {0}'.format(FPS), 0,30)
    pygame.display.flip()
    clock.tick(FPS)
    total_frames += 1

    if survivor.health <= 0:
        time.sleep(1)
        screen.blit(pygame.image.load('images/dead.jpg'), (0,0))
        pygame.display.update()
        screen.fill(black)
        Funk.text_to_screen(screen, "You scored {0} points!".format(survivor.score),704/2, 448/2, size = 50)
        break


    time.sleep(4)

You haven't done anything for `if action == "start"` – OneCricketeer Mar 20 '16 at 17:07 — OneCricketeer, Mar 20 '16 at 17:07

Looks like you are following this tutorial....

Your button isn't doing anything when you click Play, it just returns.

def button(msg,x,y,w,h,ic,ac,action=None):

    mouse = pygame.mouse.get_pos()
    click = pygame.mouse.get_pressed()
    if x+w > mouse[0] > x and y+h > mouse[1] > y:
        pygame.draw.rect(screen, (ac), (x, y, w, h))
        if click[0] == 1 and action != None:
            if action == "start":
                return               ### Fix here
            if action == "end":
                pygame.quit()
                sys.exit()

Though, you really should define a method for your actions.

def start_game():
    # TODO: Implement
    print("Starting game")

def how_to_play():
    # TODO: Implement
    print("How to")

def quit_game():
     pygame.quit()
     sys.exit()

And in the button method (from the tutorial) you only need to call the action.

if x+w > mouse[0] > x and y+h > mouse[1] > y:
    pygame.draw.rect(gameDisplay, ac,(x,y,w,h))

    if click[0] == 1 and action != None:
        action()

Then you can attach method to your buttons instead of strings.

 button("Play",100,300,100,50,green,bright_green,start_game)
 button("Controls",300,300,100,50,orange,bright_orange, how_to_play)
 button("Quit",500,300,100,50,red,bright_red, quit_game)

Hi, the problem still persists, i tried changing where i wrote 'return' to 'intro = False' in the hope that it will exit the main menu and continue with the game loop – Ahmed Abukar Mar 20 '16 at 17:27
and yes indeed i was following that tutorial – Ahmed Abukar Mar 20 '16 at 17:27
You have two different `intro` variables. Try to remove the one inside `game_intro` – OneCricketeer Mar 20 '16 at 17:28
I did i get the same result :( – Ahmed Abukar Mar 20 '16 at 17:32
I think the problem is that in the tutorial the guy uses a function instead of a game loop so he can just call the function to exit the main menu and run the game – Ahmed Abukar Mar 20 '16 at 17:35
i have updated my code to this to no avail(check original code) – Ahmed Abukar Mar 20 '16 at 17:37
Also, there is no way I can help because I don't have any of the classes or resources you used. If you could make a [mcve], that would be great. – OneCricketeer Mar 20 '16 at 17:55
