Pygame Python：功能显示运动但与类功能一起使用时不显示

Question

程序正常启动并显示带有图像的窗口，当我单击它时使用内部创建函数（代码部分旁边有2条注释）：

import Units_sol_1
import pygame
import sys

pygame.init()

clock = pygame.time.Clock()

resolution = (1080, 720)
pygame.display.set_caption("AWO")
surface = pygame.display.set_mode((1080, 720))


recon1_x = 0
recon1_y = 0

running = True

while running:

    for event in pygame.event.get():
        surface.fill((0, 0, 0))
        if event.type == pygame.QUIT:
            running = False
            pygame.quit()
            sys.exit()

        recon1 = Units_sol_1.Recon(recon1_x, recon1_y)

        pygame.display.update()

        surface.blit(recon1.icon, recon1.pos)

#this is the code below

        if recon1.pos <= pygame.mouse.get_pos() <= (recon1_x + recon1.w_icon, recon1_y + recon1.h_icon):
            print("work1")
            if event.type == pygame.MOUSEBUTTONDOWN:
                recon1_x += 1
                recon1_y += 1
                recon1.w_icon += 1
                recon1.h_icon += 1
                print(recon1.pos)

#this is the code upside

pygame.display.flip()
clock.tick(60)

在类函数 Recon (Units_sol_1) 之下：

import pygame

class Recon(Vehicule1, pygame.sprite.Sprite):
def __init__(self, posx, posy):
    super().__init__(posx, posy)
    self.pos = (posx, posy)
    self.w_icon = 33
    self.h_icon = 33

    self.icon = pygame.image.load("Unité/recon_l.png")

然后是具有类函数的相同代码，当我单击它时不会移动图像：

import Units_sol_1
import pygame
import sys

pygame.init()

clock = pygame.time.Clock()

resolution = (1080, 720)
pygame.display.set_caption("AWO")
surface = pygame.display.set_mode((1080, 720))

recon1_x = 0
recon1_y = 0

running = True

while running:

for event in pygame.event.get():
    surface.fill((0, 0, 0))
    if event.type == pygame.QUIT:
        running = False
        pygame.quit()
        sys.exit()

    recon1 = Units_sol_1.Recon(recon1_x, recon1_y)

    pygame.display.update()

    surface.blit(recon1.icon, recon1.pos)

    recon1.icon_moving(recon1_x, recon_y)

pygame.display.flip()
horloge.tick(60)

还有具有类函数的类（Units_sol_1）：

import pygame

class Recon(Vehicule1, pygame.sprite.Sprite):
    def __init__(self, posx, posy):
        self.pos = (posx, posy)
        self.w_icon = 33
        self.h_icon = 33

        self.icon = pygame.image.load("Unité/recon_l.png")

    def icon_moving(self, posx, posy):

        for event in pygame.event.get():
            if self.pos <= pygame.mouse.get_pos() <= (posx + self.w_icon, posy + self.h_icon):
                print("ok 1")
                if event.type == pygame.MOUSEBUTTONDOWN:
                    print("ok 2")
                    posx += 1
                    posy += 1
                    self.w_icon += 1
                    self.h_icon += 1
                    print(self.pos)

我的问题是我不知道如何使类函数起作用；我知道为什么当我点击它时类函数不移动图像。

您必须在应用程序循环之前创建Recon 的实例。但是，您必须在应用程序循环中连续绘制对象。 此外，当您移动对象时，您必须更改位置属性self.pos[0] 和self.pos[1]。
pygame.event.get() 获取所有消息并将它们从队列中删除。请参阅文档：

这将获取所有消息并将它们从队列中删除。 [...]

如果在多个事件循环中调用pygame.event.get()，则只有一个循环接收事件，但并非所有循环都接收所有事件。因此，似乎错过了一些事件。

每帧获取一次事件并在多个循环中使用它们或将事件列表传递给处理它们的函数和方法：

class Recon(Vehicule1, pygame.sprite.Sprite):
    def __init__(self, posx, posy):
        self.pos = [posx, posy]
        self.w_icon = 33
        self.h_icon = 33
        self.icon = pygame.image.load("Unité/recon_l.png")

    def icon_moving(self, event_list):
        for event in event_list:
            if event.type == pygame.MOUSEBUTTONDOWN:
                rect = pygame.Rect(*self.pos, self.w_icon, self.h_icon)
                if rect.collidepoint(event.pos):
                    self.pos[0] += 1
                    self.pos[1] += 1

recon1 = Units_sol_1.Recon(recon1_x, recon1_y)

running = True
while running:

    event_list = pygame.event.get()
    for event in event_list:
        surface.fill((0, 0, 0))
        if event.type == pygame.QUIT:
            running = False
           
    recon1.icon_moving(event_list)
        
    surface.fill(0)
    surface.blit(recon1.icon, recon1.pos)
    pygame.display.flip()
    clock.tick(60)

pygame.quit()
sys.exit()
