为什么我的播放器 animation 在我不动的时候仍然出现？

Question

我有它，以便我的角色在向左或向右移动时会播放行走的 animation，当他们停止移动时，他们会处于空闲状态。 animation 部分工作正常，但是当我让左/右的 go 时，它仍然可以播放并且播放器永远不会闲置。 我的播放器 animation 和播放器控件的代码如下。

def animation_state():
    global player_surface, player_index, player_rect
    

    player_index += 0.15
    if player_index >= len(player_right_walk):
        player_index = 0
    
    if LEFT == True:
        player_surface = player_left_walk[int(player_index)]
    elif RIGHT == True:
        player_surface = player_right_walk[int(player_index)]


    if LEFT == False and RIGHT == False:
        player_surface = pygame.image.load('graphics/dino_idle_right.png').convert_alpha()
    
    if event.type == pygame.KEYUP:
        if event.key == pygame.K_LEFT:
            player_surface = pygame.image.load('graphics/dino_idle_left.png').convert_alpha()
        elif event.key == pygame.K_RIGHT:
            player_surface = pygame.image.load('graphics/dino_idle_right.png').convert_alpha()

    
    screen.blit(player_surface,player_rect)

player control
def player_control():
    global LEFT, RIGHT
    player_velocity = 0
    player_gravity = 0
    

    player_gravity += 3
    player_rect.y += player_gravity
    if player_rect.bottom >= 500:
        player_rect.bottom = 500
    
    keys = pygame.key.get_pressed()

    if keys[pygame.K_LEFT]:
        player_velocity -= 11
        LEFT = True
        RIGHT = False
        if player_rect.x < -50:
            player_rect.x = 800
    elif keys[pygame.K_RIGHT]:
        player_velocity += 11
        LEFT = False
        RIGHT = True
        if player_rect.x > 800:
            player_rect.x = -50

        
    if event.type == pygame.KEYUP:
        if event.key == pygame.K_LEFT or pygame.K_RIGHT:
                player_velocity = 0

    player_rect.x += player_velocity

因为如果没有按下任何键，您不会重置LEFT和RIGHT 。 在检查键之前将LEFT和RIGHT设置为 False。 根据按下的键设置LEFT或RIGHT ：

def player_control():
    # [...]

    keys = pygame.key.get_pressed()

    LEFT = False
    RIGHT = False
    if keys[pygame.K_LEFT]:
        player_velocity -= 11
        LEFT = True
        if player_rect.x < -50:
            player_rect.x = 800
    elif keys[pygame.K_RIGHT]:
        player_velocity += 11
        RIGHT = True
        if player_rect.x > 800:
            player_rect.x = -50
