I am just new in pygame, this is my code, pieces. I have main button function, and in gameloop i i successfully create a interactive button, and i don't know exactly, how can i press the button in gameloop ("Start playing") and fill my gameDisplay, for example...white color. Thanks in advance ...........................................................................................................................................................

  • maybe in `game_loop` when you press button you should start another function - ie. `game_main_loop` - with next `while` loop. Or you have to use state variables ie. `state_display_text = True/False`, `state_display_white_color = True/False` to control which elements to display - and you can change this variables using buttons. – furas Dec 11 '17 at 19:43
  • Where did you find the code for the `button` function? A lot of people keep posting this function here and it often causes problems. Check out this [answer](https://stackoverflow.com/a/47664205/6220679) for cleaner button solutions. – skrx Dec 12 '17 at 02:39
  • Could you clarify what exactly you're trying to do? Do you just want to change the background color or switch from one scene to another (from the intro scene to the main game scene)? – skrx Dec 12 '17 at 02:47

I hope this program will help.

import pygame,sys
from pygame.locals import *

pygame.init()
screen = pygame.display.set_mode((400,400))
white=(255,255,255)
blue=(0,0,255)
bright_red = (255,0,0)
red = (200,0,0)
black=(0,0,0)
color=white

def changecolor(newcolor):
    global color
    color=newcolor

while True:
    screen.fill(color)

    for event in pygame.event.get():
        if event.type == QUIT:
            pygame.quit()
            sys.exit()
        elif event.type == MOUSEBUTTONUP:
            # Whenever somebody clicks on the screen the color
            # will change from the initial color to the color
            # value you send to the function. Using this you could
            # make it specifically for your button. Like calling
            # the change color function whenever the button is clicked.
            changecolor(blue)

    pygame.display.update()

You can use state variables (True/False) to control which element to display and you can change those varibles using button.

In example I have 

    display_text = True
    display_button_1 = True
    display_button_2 = False

to control when display text and two buttons.

First button change values and it hides text and first button, and it shows second button.

There is one problem - your button function is ugly and it use get_buttons() so when I hold pressed button and I remove one button and put another in the same place then it automatically click second button. You should use event.type == MOUSEBUTTONUP (as suggest @Hilea) to fix this.

        pygame.draw.rect(gameDisplay, ac,(x,y,w,h))
