Question

我正在为pygame创建一个类，该类将允许用户为其游戏创建文本框。我的代码由于某种原因未到达mousebuttondown部分。我将整个代码与遇到问题的部分一起附加。

未完成打印

def main(self, events, mousepos, id):
    for event in events:
        if event.type == pygame.QUIT:
            exit()
        if event.type == pygame.MOUSEBUTTONDOWN:
            if self.rect(id, mousepos):
                print("done")

保留打印否

def rect(self, text_id, mousepos):
    x, y, width, height = self.dict_all[text_id]
    if ((x + width) > mousepos[0] > x) and ((y + height) > mousepos[1] > y):
        print("yes")
        return True
    else:
        print("no")
        return False

下面的整个代码，更新是我试图制作的一种方法，但由于某种原因无法使用。

import pygame

pygame.font.init()


class textBox:
    def __init__(self, surface, id, color, width, height, x, y, antialias, maxtextlen):
        self.surface = surface
        self.id = id
        self.color = color

        pygame.draw.rect(self.surface, (self.color), (self.x, self.y, self.width, self.height))
        # for i in self.text_list_keys:
        #     if self.id not in i:
        #         self.text_list_keys.append(self.id)
        #         self.text_list.append(tuple(self.id))

                            new_t = t
                        self.text_list[new_t].append("a")
                        self.surface.blit(self.font.render(f'{self.text_list[new_t]}', self.antialias, (0, 0, 0)),
                                          (self.x, self.y))

                    else:

            else:

test.py

import pygame
from pygame_textbox import textBox

pygame.init()

win_width = 500
win_height = 500

screen = pygame.display.set_mode((win_width, win_height))
pygame.display.set_caption("test")

run = True
while run:
    mouse = pygame.mouse.get_pressed()
    screen.fill((0, 0, 0))
    events = pygame.event.get()
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False
            pygame.quit()
            exit()

    a = textBox(screen, 1, (255,  255, 255), 100, 30, 100, 100, True, 20)
    # a.getId(1)
    a.rect(1, mouse)
    a.main(events, mouse, 1)
    pygame.display.update()

Answer 1

方法main的第二个参数必须是鼠标位置，而不是鼠标按钮：

run = True
while run:
    # [...]

    mouse_pos = pygame.mouse.get_pos()
    a.main(events, mouse_pos, 1)

    # [...]

当pygame.mouse.get_pressed()表示所有鼠标按钮状态的布尔值序列时，pygame.mouse.get_pos()返回鼠标光标的X和Y位置。

为什么我的pygame.MOUSEBUTTONDOWN无法正常工作？
