在 Pygame 中为无尽的跑酷游戏制作障碍系统
Making an Obstacle System for an Endless Runner Game in Pygame
我正在尝试在 Python pygame 中复制 google chrome dinosaur game。我对 pygame 没有太多经验。我设法创建了所有的恐龙精灵动画（行走、跳跃和弯曲），现在我正在尝试添加障碍物。所以我想做的是当用户的分数超过 35 时，障碍物将开始随机生成。问题是，当分数超过 35 时，障碍物层层叠叠，有的不断出现又消失，看起来很糟糕，非常滞后。我怎样才能更顺利地渲染障碍物？代码的相关部分：

我怀疑您的代码存在一个问题，即 pygame.display.update() 可以同时被调用：
- 通过
draw函数的主程序；
- 以及当得分大于 35 时通过
draw_obstacles 函数启动的线程。
这可以解释为什么有些障碍物出现和消失得很快。也许，只需删除函数 draw_obstacles 中的 pygame.display.update() 就可以解决这个问题。
另一个可以解释滞后的问题与您启动线程的条件有关。在我看来，一旦分数超过 35，您将在主循环的每次迭代中启动另一个线程，这意味着 lot 个线程。因此，除非您的代码中有某些条件可以防止这种情况发生，否则您应该添加一个。
[编辑]看完你的完整代码后我注意到了一些问题。
首先，如前所述，您应该 pygame.display.update()
在你的主循环中只有 一次。 WINDOW.fill 也一样
put 在你的代码中有几个地方。这就是造成效果的原因
物体出现和消失的速度非常快。
您的程序（以及每个 pygame 程序）应该具有以下内容
结构。
while run:
process_events_and_change_objects_status()
WINDOW.fill("#FFFFFF")
redraw_everything()
pygame.display.update()
wait()
并且不应该有任何其他调用 WINDOW.fill 或
pygame.display.update() 其他任何地方。
二、看fall方法：
def fall(self):
if self.is_falling:
while self.y != 323:
self.y += 20
self.walk()
WINDOW.fill("#FFFFFF")
self.is_falling = False
self.is_jumping = False
pygame.display.update()
在这里你试图同时做两件事：更新
对象状态并使用 self.walk 重绘所有内容。那很糟
因为，例如，如果当前屏幕上有障碍物，
他们不会被绘制，因为 self.walk 不关心障碍物。此外，这意味着在恐龙坠落时无法处理事件。
所以你必须将它更改为只更新对象状态
类似的东西。
def fall(self):
if self.is_falling:
self.y += 20
if self.y != 323:
self.is_falling = False
self.is_jumping = False
然后重绘将由主循环中的self.walk管理。相同的
对于 bend 和 jump.
所以我认为你需要修改你的程序结构才能
在您的代码中将绘图部分与处理明确分开
部分（处理事件和更新恐龙状态）。除此以外
如果你把两者混在一起，你将面临你现在面临的那种问题
并且您的代码将无法维护和发展。

我怀疑您的代码存在一个问题，即 pygame.display.update() 可以同时被调用：
- 通过
draw函数的主程序； - 以及当得分大于 35 时通过
draw_obstacles函数启动的线程。
这可以解释为什么有些障碍物出现和消失得很快。也许，只需删除函数 draw_obstacles 中的 pygame.display.update() 就可以解决这个问题。
另一个可以解释滞后的问题与您启动线程的条件有关。在我看来，一旦分数超过 35，您将在主循环的每次迭代中启动另一个线程，这意味着 lot 个线程。因此，除非您的代码中有某些条件可以防止这种情况发生，否则您应该添加一个。
[编辑]看完你的完整代码后我注意到了一些问题。
首先，如前所述，您应该 pygame.display.update()
在你的主循环中只有 一次。 WINDOW.fill 也一样
put 在你的代码中有几个地方。这就是造成效果的原因
物体出现和消失的速度非常快。
您的程序（以及每个 pygame 程序）应该具有以下内容 结构。
while run:
process_events_and_change_objects_status()
WINDOW.fill("#FFFFFF")
redraw_everything()
pygame.display.update()
wait()
并且不应该有任何其他调用 WINDOW.fill 或
pygame.display.update() 其他任何地方。
二、看fall方法：
def fall(self):
if self.is_falling:
while self.y != 323:
self.y += 20
self.walk()
WINDOW.fill("#FFFFFF")
self.is_falling = False
self.is_jumping = False
pygame.display.update()
在这里你试图同时做两件事：更新
对象状态并使用 self.walk 重绘所有内容。那很糟
因为，例如，如果当前屏幕上有障碍物，
他们不会被绘制，因为 self.walk 不关心障碍物。此外，这意味着在恐龙坠落时无法处理事件。
所以你必须将它更改为只更新对象状态
类似的东西。
def fall(self):
if self.is_falling:
self.y += 20
if self.y != 323:
self.is_falling = False
self.is_jumping = False
然后重绘将由主循环中的self.walk管理。相同的
对于 bend 和 jump.
所以我认为你需要修改你的程序结构才能 在您的代码中将绘图部分与处理明确分开 部分（处理事件和更新恐龙状态）。除此以外 如果你把两者混在一起，你将面临你现在面临的那种问题 并且您的代码将无法维护和发展。
