PyGame hitbox闪烁

Question

我试图用pyplay制作一个游戏，我几乎完成了，但我想让被画在墙上的盒子不闪烁，这些红色的盒子在整个游戏中闪烁，我不想让它们闪烁，最后，我在一个if条件下调用player碰撞函数，在这里每当我制作新的碰撞器时，我每次都要在if条件下添加函数，我想要的是碰撞器对象自动调用这个函数，而不需要我在if语句中为碰撞器的每个实例调用它对象。请指导我如何这样做。

def redrawGameWindow():
    win.blit(bg, (-50,-200))
    man.draw(win)
    #man.drawhitbox(win)
    pygame.display.update()


#mainloop

man = player(200, 410, 64,64)
run = True
while run:
    collider1 = wall(500, 400, 200, 200, True)
    collider2 = wall(200,100,50, 50, False)
    collider3 = wall(700,100,50, 50, False)
    collider4 = wall(900,100,50,50, True)
    clock.tick(60)
    
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False

    keys = pygame.key.get_pressed()
    x, y = man.x, man.y

    if keys[pygame.K_a] and man.x > man.vel:
        x -= man.vel
        man.left = True
        man.right = False
    elif keys[pygame.K_d] and man.x < scrWidth - man.width - man.vel:
        x += man.vel
        man.right = True
        man.left = False
    elif keys[pygame.K_w] and man.y > man.vel:
        y -= man.vel
        man.left = False
        man.right = False
    elif keys[pygame.K_s] and man.y < scrHeight - man.height - man.vel:
        y+= man.vel
        man.left = False
        man.right = False
    else:
        man.right = False
        man.left = False
        man.walkCount = 0

    man.hitbox(15, 0, 31, 17)
    player_rect = pygame.Rect(x, y, 50, 55)
    if collider2.playerCollide(player_rect) == False and collider1.playerCollide(player_rect) == False and collider3.playerCollide(player_rect) == False and collider4.playerCollide(player_rect) == False:
        man.x, man.y = x, y
    redrawGameWindow()
pygame.quit()

该问题是由对pygame的多次调用引起的。陈列更新（）。删除对pygame的调用。陈列从类wall更新（），只需执行1个pygame。陈列update（）在重画游戏窗口的末尾
但是，在绘制框之前必须先绘制背景，否则背景将覆盖框：

def redrawGameWindow():
    # win.blit(bg, (-50,-200)) <--- DELETE
    man.draw(win)
    #man.drawhitbox(win)
    pygame.display.update()

run = True
while run:
    win.blit(bg, (-50,-200)) # <--- ADD

    collider1 = wall(500, 400, 200, 200, True)
    collider2 = wall(200,100,50, 50, False)
    collider3 = wall(700,100,50, 50, False)
    collider4 = wall(900,100,50,50, True)

    # [...]

    redrawGameWindow()

通过创建碰撞器列表简化代码：

colliders = [
   wall(500, 400, 200, 200, True),
   wall(200,100,50, 50, False),
   wall(700,100,50, 50, False),
   wall(900,100,50,50, True)] 

player_rect = pygame.Rect(x, y, 50, 55)
if not any(c.playerCollide(player_rect) for c in colliders):
    man.x, man.y = x, y
