如何在Pygame中為圖片添加點擊事件？

Question

我有以下代碼。 它基本上從文件夾應用程序及其子文件夾中獲取所有圖像。 我的問題是我試圖將click事件添加到所有圖像中以執行相同的操作。 基本上是“ exec("apps/" + apps[app_count] + "/app.py" ）“

# -*- coding: utf-8 -*-
from pygame import *
import os
import pygame
import time
import random
import sys

_image_library = {}

class SeedOS():

    def home(self):
        (width, height) = (240, 320)
        screen = pygame.display.set_mode((width, height))
        pygame.display.set_caption('Seed OS')
        pygame.font.init() 
        Font30 = pygame.font.SysFont('Arial', 30)
        WHITE = (255,255,255)
        BLACK = (0,0,0)
        screen.fill(WHITE)
        apps = os.walk("apps").next()[1]
        app_count = 0
        icon_width = 15
        icon_height = 0
        max_width = 155
        pygame.display.flip()
        while True:
            while app_count < len(apps):
                print apps[app_count]
                image = pygame.image.load("apps/" + apps[app_count] + "/app.png").convert()
                screen.blit(image, (icon_width, icon_height))
                icon_width+=70
                if icon_width > max_width:
                    icon_width = 15
                    icon_height +=70
                app_count += 1
            time2 = time.strftime('%H:%M:%S')
            pygame.display.flip()
            pygame.draw.rect(screen,BLACK,(0,290,240,30))
            clock = Font30.render(time2, False, WHITE)
            screen.blit(clock,(60,288))
            for event in pygame.event.get():
                if event.type == pygame.QUIT:
                    pygame.quit()
                    sys.quit()

phone = SeedOS()
phone.home()

這是檢查“ apps”文件夾中所有內容的代碼部分

while app_count < len(apps):
                    print apps[app_count]
                    image = pygame.image.load("apps/" + apps[app_count] + "/app.png").convert()
                    screen.blit(image, (icon_width, icon_height))
                    icon_width+=70
                    if icon_width > max_width:
                        icon_width = 15
                        icon_height +=70
                    app_count += 1

並附加每個文件夾中的所有圖像。 我希望在每個圖標上單擊，執行它的“ app.py”，因為在每個應用程序文件夾中都有兩個文件：“ app.png”和“ app.py”。

您可以在apps列表中添加每個圖像的坐標，然后將這些坐標與pygame.mouse.get_pos()方法一起使用：

while True:
            while app_count < len(apps):
                print apps[app_count]
                apps[app_count] = (apps[app_count], icon_width, icon_height)  # Adding coordinates to the list
                image = pygame.image.load("apps/" + apps[app_count][0] + "/app.png").convert() # Adding an index to find the image in the tuple
                screen.blit(image, (icon_width, icon_height))
                icon_width+=70
                if icon_width > max_width:
                    icon_width = 15
                    icon_height +=70
                app_count += 1
            time2 = time.strftime('%H:%M:%S')
            pygame.display.flip()
            pygame.draw.rect(screen,BLACK,(0,290,240,30))
            clock = Font30.render(time2, False, WHITE)
            screen.blit(clock,(60,288))
            for event in pygame.event.get():
                if event.type == pygame.QUIT:
                    pygame.quit()
                    sys.quit()
                if event.type == pygame.MOUSEBUTTONDOWN:
                    if event.button == 1: # MOUSEBUTTONLEFT
                        for a in apps:
                            if a[1] < pygame.mouse.get_pos()[0] < a[1]+IMAGEWIDTH and a[2] < pygame.mouse.get_pos()[1] < a[2] + IMAGEHEIGHT:
                                # Instruction to launch ("apps/" + a[0] + "/app.py")

您要做的就是定義圖標的寬度和高度pygame.Surface.get_size()如果每個應用程序都不相同，可以使用pygame.Surface.get_size()進行操作），並用正確的語法替換最后一行。 在Windows上，您可以使用：

os.system("apps\\"+a[0]+"\\app.py") # of course you should import os first
