Python 游戏运动
Python Game Movement
我正在模拟一个商业问题，但我正在尝试构建一个 2d 游戏来演示模拟的动作。
为此，我从一个真正的 python 游戏开始，我在网上找到了一些代码。
目标是通过随机整数创建 100 次模拟运动（上、下、左、右、停止）。比如random = 1，则向左移动。
由于某种原因，我可以发送第一个动作，但是游戏忽略了第二个到第 100 个动作。
有人可以提示我做错了什么吗？
我将不胜感激某人的专业知识。

就像@Blckknght 指出的那样，绘制图层 Game 和 运行 它的其他预定函数（在您的情况下 Game.update）仅在调用 cocos.director.director.run(game_scene).这就是为什么您看不到速度更新的原因 - 它们是在绘图开始时完成的。
您应该删除调用 game_layer.simulate()，因为它没有达到预期的效果。
那么你可以这样做：
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 的调用。不确定这些是否会导致问题，但最好在 cocos2d.
中调用专用 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，您必须更改函数的签名以将 dt 作为其第二个参数，就像 Game.update 一样。
