Question

我试图用pygame制作一种虚拟电话程序，只是为了进行试验，但是遇到了一个问题。我已经加载了图像，然后将其在屏幕的左下方涂上了斑点。但是，当我执行print(imagename.get_rect())时，它会在屏幕的0，0处打印出一个位置。鼠标也在那里碰撞。我不明白什么？

def aloitus(): #goes back to the home screen
    cls() #clears the screen
    tausta = pygame.image.load("./pyhelin.png") #load background
    tausta = pygame.transform.scale(tausta, (360, 640)) #scale it 
    screen.blit(tausta, (0, 0)) #blit it
    alapalkki = pygame.Surface((600, 100)) #ignore
    alapalkki.set_alpha(120)
    alapalkki.fill(blonk)
    screen.blit(alapalkki, (0, 560))
    global messenger #this is the thing!
    messenger = pygame.image.load("./mese.png").convert_alpha() #load image
    print(messenger.get_rect()) #print its location
    messenger = pygame.transform.scale(messenger, (60,65)) #scale it to the correct size
    screen.blit(messenger, (10, 570)) # blit on the screen
    update() #update screen
aloitus() # at the start of the program, go to the home screen
while loop: #main loop
    for event in pygame.event.get():
         if event.type == pygame.MOUSEBUTTONDOWN:
            # Set the x, y postions of the mouse click
            x, y = event.pos
            if messenger.get_rect().collidepoint(x, y): #messenger is the image defined earlier
                #do things
                print("hi")

点击图像“ hi”时，预期结果将被打印。实际结果是，当单击左上角hi时将被打印。

get_rect返回一个pygame.Rect，其默认的左上坐标为（0，0）。您需要随后设置坐标或将其作为关键字参数传递给get_rect。

我建议将rect分配给另一个变量，并以下列方式之一设置坐标：

messenger_rect = messenger.get_rect()
messenger_rect.x = 100
messenger_rect.y = 200
# or
messenger_rect.topleft = (100, 200)
# or pass the coords as an argument to `get_rect`
messenger_rect = messenger.get_rect(topleft=(100, 200))

还有更多rect attributes可以分配坐标：

x,y
top, left, bottom, right
topleft, bottomleft, topright, bottomright
midtop, midleft, midbottom, midright
center, centerx, centery

Pygame的表面位置似乎与屏幕上的不同？
