Pygame 不检测鼠标点击

Question

#The induvidual squares
class Square():
    def __init__(self,x,y):
        self.x = x
        self.y = y

#The grid as a whole
class Grid():
    def __init__(self,width,height):
        self.squares = []
        self.objects = []
        self.width = width
        self.height = height

    def populate(self):
        for i in range(1,self.height + 1):
            for j in range(1,self.width + 1):
                self.squares.append(Square(j,i))

grid = Grid(10,10)
grid.populate()
for i in grid.squares:
      grid.objects.append(pygame.Rect((i.x -1) * 50,(i.y - 1) * 50,50,50))

While True:

    for event in pygame.event.get():
        if event.type == pygame.MOUSEBUTTONDOWN :
            print("HELLO") #Testing to see if it worked
            (x,y) = pygame.mouse.get_pos()
            for i in grid.objects:
                if i.x*50 <= (x) < (i.x+1)*50:
                    if i.y*50 <= (y) < (i.y+1)*50:
                        print("hi") #Testing to see if it worked

我一直在尝试创建网格并使用它们制作游戏。我正在考虑能够单击网格的某个方块，这会导致该方块发生变化。

这是我试图让它注册我是否点击了任何方块的地方，但是它根本没有注册我是否点击过。我查看了有关该主题的其他讨论并且 none 有效。

pygame.Rect 对象的 .x 和 .y 组件包含矩形的实际左上角位置。乘以 50 是错误的：

while True:

    for event in pygame.event.get():
        if event.type == pygame.MOUSEBUTTONDOWN :
            print("HELLO") #Testing to see if it worked
            x, y = pygame.mouse.get_pos()
            for obj_rect in grid.objects:
                if obj_rect.x <= x < obj_rect.x+50:
                    if obj_rect.y <= y < obj_rect.y+50:
                        print("hi") #Testing to see if it worked

无论如何我建议简化代码并使用 collidepoint

x, y = pygame.mouse.get_pos()
for obj_rect in grid.objects:
    if obj_rect.collidepoint((x, y)):
        print("hi") #Testing to see if it worked

我找到了一个与我有另一个相关的修复程序

对于 pygame.event.get()

中的事件

在同一个 while 循环中。此事件检查用于检测我是否曾尝试退出 window。 ~~似乎 pygame 在同一个循环中进行两个事件检查有问题，可能与使用相同变量名的它们有关~~，不管怎样，我把我的检查移到了同样的 for 循环，它现在可以工作了

while True:

for event in pygame.event.get():
    print(event)
    if event.type == QUIT:
        pygame.quit()
        sys.exit()

    if event.type == pygame.MOUSEBUTTONDOWN :
        print("HELLO")
        x, y = pygame.mouse.get_pos()
        for obj_rect in grid.objects:
            if obj_rect.collidepoint((x, y)):
                print("hi") #Testing to see if it worked
