我是使用 Python 的 SciTE 的新成员和新手程序员。我有一个项目，我必须制作一个游戏，其中涉及保持动画人物跳千斤顶的时间，我正在尝试运行它，只是为了表明我的列表对象在引擎功能中没有“更新” . 我有一段很长的代码。我试图找出问题所在。
定时器类：
def __init__(self,position,start_value,size = 20,color = gc.WHITE,font = "Arial"):
''' Initializes the timer.
Start value is in seconds. '''
self.original_time = start_value
self.time = start_value
self.max = start_value * 1000
self.x = position[0]
self.y = position[1]
self.size = size
self.color = color
self.font = font
self.active = False
pass
def is_active(self):
""" Tells the program if the timer is on. """
return self.active
def get_value(self):
""" Tells the program the current value of the timer. """
return self.time
def start(self,time = None):
""" Starts the timer. """
self.active = False
self.time = self.original_time
pass
def update(self,time):
""" Iterates the value of the timer.
deactivate returns True if the timer reaches zero. """
deactivate = False
if self.active:
#
# Iterate time
#
self.time -= time
#
# Deactivate the timer when the countdown finishes.
#
if self.time <= 0:
self.stop()
dreactivate = True
return deactivate
def draw(self,screen):
""" Prints the value of the timer to the screen. """
output = format_time(self.time)
position = [self.x, self.y]
#
# Print the output string
#
gc.screenprint(screen,outpit,position)
引擎：
#
# MVC FUNCTIONS
#
def engine(interval,avatar,timer):
''' The engine models the physics of your game by updating object
positions, checking for collisions, and resolving them. '''
score = False
if avatar != None:
score = avatar.update(interval)
timer.update(interval)
return score
