Pyganim动画Bug

Question

我有一个非常奇怪的错误，我无法深究。当我玩我作为项目创建的游戏时，我按下攻击按钮J角色会像他应该的那样播放攻击动画。他以1-5倍的正确方式完成任务。然而，一旦他这样做（并且我不确定它如何决定它想要显示多少次），它将不再播放动画。我真的很感激任何人对此的帮助。有关Pyganim的参考，请查看here。

这是我的代码：

#Setup movement keys
rightPressed = False
leftPressed = False
facing = True #True if facing right, false if facing left
level = 1
idlePaused = False#Checks for Pyganim pausing the animation
runStopped = True#Checks if the character running is stopped
isAttacking = False#If attacking no other animation will play

def updateDisplay():
    pygame.display.flip()

    keysPressed = pygame.key.get_pressed()
    if keysPressed[inputKey]:
        return True

我为代码块道歉，但所有这些都有必要向您展示最新情况。
