我正在为一个商业问题进行模拟，但我正在尝试构建一个2D游戏来演示模拟的动作。
要做到这一点，我开始使用一个实际的python游戏，我找到了一些在线代码。
目标是通过随机整数创建100个模拟运动（向上，向下，向左，向右，停止）。例如，random = 1，然后向左移动。
出于某种原因，我能够发送第一个动作，但游戏会忽略第二个到第100个动作。
有人可以给我一个关于我做错的提示吗？
我非常感谢某人的专业知识。

答案 0 :(得分：1)
像@Blckknght所指出的那样，绘制图层Game并运行其他计划函数（在您的情况下为Game.update）仅在调用cocos.director.director.run（game_scene）之后启动。这就是为什么你看不到速度更新 - 它们是在绘图开始时完成的。
您应该删除通话game_layer.simulate()，因为它没有达到预期的效果。
然后你可以这样做：
def simulate(self, dt):
if self.x > 0: # set this to 100 in constructor
rand = random.randint(1,5)
if rand == 1:
self.movePlayer("left")
print("left")
elif rand == 2:
self.movePlayer("right")
print("right")
elif rand == 3:
self.movePlayer("up")
print("up")
elif rand == 4:
self.movePlayer("down")
print("down")
elif rand == 5:
self.movePlayer("space")
print("space")
x -= 1
请注意，我删除了对time.sleep的来电。不确定这些是否会导致问题，但最好在cocos2d中调用专用的schedule_interval（或schedule）函数。
在Game的构造函数中：
self.schedule_interval(self.simulate, 0.05)
self.schedule_interval(self.update, 0.05)
要安排Game.simulate，您必须更改该功能的签名，以dt作为其第二个参数，例如Game.update。
