使用 Pygame 创建矩形按钮

Question

我正在尝试在 Pygame 中使用 rect 制作按钮。我从红色退出按钮开始，检查点击是否在按钮的边界框内。

     import pygame
"""import nemesis.py;"""

pygame.init();
screen = pygame.display.set_mode((400,300));
pygame.display.set_caption("menu");
menuAtivo = True;

start_button = pygame.draw.rect(screen,(0,0,240),(150,90,100,50));
continue_button = pygame.draw.rect(screen,(0,244,0),(150,160,100,50));
quit_button = pygame.draw.rect(screen,(244,0,0),(150,230,100,50));

pygame.display.flip();

while menuAtivo:
    for evento in pygame.event.get():
        print(evento);
        if evento.type == pygame.MOUSEBUTTONDOWN:
            if pygame.mouse.get_pos() >= (150,230):
                if pygame.mouse.get_pos() <= (250,280):
                        pygame.quit();

TKS 伙计们，

这是我的回答：

 import pygame

pygame.init();
screen = pygame.display.set_mode((400,300));
pygame.display.set_caption("menu");
menuAtivo = True;

start_button = pygame.draw.rect(screen,(0,0,240),(150,90,100,50));
continue_button = pygame.draw.rect(screen,(0,244,0),(150,160,100,50));
quit_button = pygame.draw.rect(screen,(244,0,0),(150,230,100,50));

pygame.display.flip();

def startGame():
    screen.fill((0,0,0));
    pygame.display.flip();
    import nemesis.py;

while menuAtivo:
    for evento in pygame.event.get():
        print(evento);
        if evento.type == pygame.MOUSEBUTTONDOWN:
            if pygame.mouse.get_pos()[0] >= 150 and pygame.mouse.get_pos()[1] >= 230:
                if pygame.mouse.get_pos()[0] <= 250 and pygame.mouse.get_pos()[1] <= 280:
                        pygame.quit();
            if pygame.mouse.get_pos()[0] >= 150 and pygame.mouse.get_pos()[1] >= 90:
                if pygame.mouse.get_pos()[0] <= 250 and pygame.mouse.get_pos()[1] <= 140:
                        startGame();

在 pygame 中使用 rects 时，最好使用内置的碰撞检测。这是有关如何执行此操作的示例代码，希望它可以帮助您解决问题。

在此之前，虽然我想提一下你应该使用 while 循环渲染/绘制你的对象，否则不会出现。

 import pygame
import sys

def main():
    pygame.init()
    clock = pygame.time.Clock()
    fps = 60
    size = [200, 200]
    bg = [255, 255, 255]

    screen = pygame.display.set_mode(size)

    button = pygame.Rect(100, 100, 50, 50)  # creates a rect object
    # The rect method is similar to a list but with a few added perks
    # for example if you want the position of the button you can simpy type
    # button.x or button.y or if you want size you can type button.width or
    # height. you can also get the top, left, right and bottom of an object
    # with button.right, left, top, and bottom

    while True:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                return False

            if event.type == pygame.MOUSEBUTTONDOWN:
                mouse_pos = event.pos  # gets mouse position

                # checks if mouse position is over the button

                if button.collidepoint(mouse_pos):
                    # prints current location of mouse
                    print('button was pressed at {0}'.format(mouse_pos))

        screen.fill(bg)

        pygame.draw.rect(screen, [255, 0, 0], button)  # draw button

        pygame.display.update()
        clock.tick(fps)

    pygame.quit()
    sys.exit

if __name__ == '__main__':
    main()
