• pygame mouse clicking detection 3 answers

i'm adding title screen game, , want add "play" button launch main game when user clicks it.

i have set up, i'm not sure command have mouse interact play button image.

first, have play button image loaded outside of main loop

play = pygame.image.load("play.png").convert() 

then, have blit on screen, rectangle behind marker

play_button = pygame.draw.rect(screen, white, [365, 515, 380, 180]) screen.blit(play, [350, 500]) 

pygame low-level library - has no gui widgets , have many things on own.

it easier create class button , use many times.

here example class button. when click change color.

event_handler() checks button click.

import pygame  # --- class ---  class button(object):      def __init__(self, position, size):          # create 3 images         self._images = [             pygame.surface(size),                 pygame.surface(size),                 pygame.surface(size),             ]          # fill images color - red, gree, blue         self._images[0].fill((255,0,0))         self._images[1].fill((0,255,0))         self._images[2].fill((0,0,255))          # image size , position         self._rect = pygame.rect(position, size)          # select first image         self._index = 0      def draw(self, screen):          # draw selected image         screen.blit(self._images[self._index], self._rect)      def event_handler(self, event):          # change selected color if rectange clicked         if event.type == pygame.mousebuttondown: # button clicked             if event.button == 1: # left button clicked                 if self._rect.collidepoint(event.pos): # mouse on button                     self._index = (self._index+1) % 3 # change image  # --- main ---  # init          pygame.init()  screen = pygame.display.set_mode((320,110))  # create buttons  button1 = button((5, 5), (100, 100)) button2 = button((110, 5), (100, 100)) button3 = button((215, 5), (100, 100))  # mainloop  running = true  while running:      # --- events ---      event in pygame.event.get():         if event.type == pygame.quit:             running = false          # --- buttons events ---          button1.event_handler(event)         button2.event_handler(event)         button3.event_handler(event)      # --- draws ---      button1.draw(screen)     button2.draw(screen)     button3.draw(screen)      pygame.display.update()  # --- end ---  pygame.quit()
