【问题描述】：

我知道如何使用 Pyganim，它相当简单。但我的问题在于我如何构建我的游戏，它每秒启动 60 次 pyganim 的动画，因此它根本不会动画（根据人眼）。在如何判断动画当前是否正在播放以及之后是否调用播放方面，我需要帮助？

我的代码：

class gameStart(pygame.sprite.Sprite):
def __init__(self):
    pygame.sprite.Sprite.__init__(self)
    self.background = pygame.image.load("BG" + str(level) + ".png")
    self.player = pygame.image.load("2_scaled.png")
    self.icon = pygame.image.load("1_scaled.png")
    self.background_S = pygame.transform.scale(self.background, (width, height)) #Scale the background to match the screen resolution
    screen.blit(self.background_S, (0,0))
    screen.blit(self.player, (0, height/2))
    screen.blit(self.icon, (0,0))
    self.position = self.player.get_rect()
    self.health = 100
    #Setup the players Idle, Attack, Attack 2 and Death Animations
    self.PlayerIdleAnim = pyganim.PygAnimation([('2_scaled.png', 1), ('3_scaled.png', 1), ('4_scaled.png', 1), ('5_scaled.png', 1), ('6_scaled.png', 1)])
    updateDisplay()

def move(self):
    global rightPressed
    global leftPressed
    global facing
    global frame
    leftPressed = False
    rightPressed = False
    if keyPressed(K_a):
        leftPressed = True
    elif keyPressed(K_d):
        rightPressed = True
    elif not keyPressed(K_a):
        leftPressed = False
    elif not keyPressed(K_d):
        rightPressed = False


    if rightPressed and (self.position.x < width - 200):
        self.position.x += moveSpeed
        screen.blit(self.background_S, (0,0))
        self.PlayerIdleAnim.stop()
        screen.blit(self.player, (self.position.x, height/2))
        if not facing:
            self.player = pygame.transform.flip(self.player, True, False)
            facing = True
        updateDisplay()
    elif leftPressed and (self.position.x > 20):
        self.position.x += -moveSpeed
        screen.blit(self.background_S, (0,0))
        self.PlayerIdleAnim.stop()
        if facing:
            self.player = pygame.transform.flip(self.player, True, False)
            facing = False
        screen.blit(self.player, (self.position.x, height/2))
        updateDisplay()
    elif not leftPressed and not rightPressed:
        if not facing:
            self.PlayerIdleAnim.flip(True, False)
            self.PlayerIdleAnim.play()
        else:
            self.PlayerIdleAnim.play()
    """elif rightPressed and not (self.position.x < width - 200):
        rightPressed = False
    elif leftPressed and not (self.position.x > 200):
        leftPressed = False"""




game = gameStart()

while not gameQuit:
    for event in pygame.event.get():
        if event.type == QUIT:
            gameQuit = True
        elif event.type == KEYDOWN:
        if event.key == K_ESCAPE:
            gameQuit = True
    game.move()
    updateDisplay()
    fpsClock.tick(fps)

从技术上讲，动画永远不会运行，因为它总是停留在第一帧。但是，如果您确实想知道它是否会运行，如果您给它时间切换帧，只需在按下让动画运行的键时才激活循环。类似...

def anim_test():
    clock = pg.time.Clock()
    while run == true:
        pg.display.update()
        clock.tick(60)
