Movie about a girl who had another different life when she dreamed What do you call this alternating melodic pattern? self.dt_update = 0.0 self.dt_frame = 0.0 # Metrics: how much real time a callback consumes self.cost_of_update = 0.0 self.cost_of_frame = 0.0 # Metrics: average updates and frames per second over the calling Sleep(0) (underlying system API) just releases the rest of your current timeslice. http://3swindows.com/cpu-usage/how-to-fix-high-cpu-usage.html

A notable distinction is there are two collision conditions that change the ball's behavior: collision with the screen edges and collision with another ball. http://www.gamedev.net/topic/518494-pygame-eating-up-my-cpu/

Pygame High Cpu Usage

By contrast, when two balls collide it does not visually matter whether they react immediately or there is a delay, even at a very low 6 updates-per- second. Install it with $ pip install memory_profiler 1 $ pip install memory_profiler Also, it is recommended to install the psutil package, so that the memory_profile runs faster: $ pip install psutil The GameClock class is purely Python and should be compatible with other Python-based multi-media and game development libraries. """ __version__ = '$Id: gameclock.py 428 2013-08-28 05:43:47Z [emailprotected] $' __author__ = Handle screen edge collisions. ## 2.

  1. This module has to be installed first, with $ pip install line_profiler 1 $ pip install line_profiler Next, you need to specify which functions you want to evaluate using the @profile

  5. There's also a method I don't recall offhand for controlling the program's speed more precisely at the expense of still using 100% CPU, but you probably don't need it.

  9. Use the memory_profiler module The memory_profiler module is used to measure memory usage in your code, on a line-by-line basis.

The update_ready and frame_ready public attributes have been removed. If the game mechanics are comparatively more costly in computing power, there is potentially a lot of benefit in choosing to update the mechanics at a much lower rate than updating If not, see /www.gnu.org/licenses/>. # Compatible: Python 2.7, Python 3.2 """gameclock.py - Game clock for Gummworld2.

Using the timeit module Anther option is to use the timeit module, which gives you an average time measure. http://osdir.com/ml/python.pygame/2003-07/msg00042.html These tips assume the stock (unmodified) settings are used. 1.

The frame_callback receives a single INTERPOLATION argument, which is the fractional position in time of the frame within the current update time- step. http://3swindows.com/cpu-usage/wmi-high-cpu-usage.html You'll see that the total amount of time spent on running your script is higher than before. update_interval = self._update_interval game_time = self._game_time if real_time >= self._next_update: self.dt_update = update_interval # fixed timestep: good self._last_update_real = real_time game_time += update_interval self._game_time = game_time self._last_update = game_time self._next_update = self.ups = 0.0 self.fps = 0.0 @property def max_ups(self): return self._max_ups @max_ups.setter def max_ups(self, val): self._max_ups = val self._update_interval = 1.0 / val @property def max_fps(self): return self._max_fps @max_fps.setter def max_fps(self,

How to copy text from command line to clipboard without using the mouse? have a peek here Right now your program is always doing everything as fast as it can, rather than giving some time for the Pi to rest or do something else.

The solution is to limit the framerate to 30, then you have almost no CPU load when doing nothing while keeping an eventloop running to react to users events.

There are many ways to solve this scenario.

This is easier than trying to shoehorn all that logic into a single loop and select based on game state. this would be more useful in larger games, but overkill for an image viewer. puzzle() sets up its own event loop - note that they all use the same event queue, but take over polling it so that the effect of the same event can

The distinction is that predicting screen edge collision makes a visible difference. running = True while running: for evt in pygame.event.get(): if evt.type == pygame.QUIT: running = False elif evt.type == pygame.KEYDOWN: if evt.key == pygame.K_ESCAPE: PostQuitEvent() ...if __name__ == '__main__': main() Back If your task is checking for the output of a subprocess, you can just subprocess.wait() for it to finish, for example. Check This Out Hope it was useful! šŸ™‚ Don't forget to share it with your friends!

the wait method is simple, but it doesn't get the cpu usage as low as it can go, and it doesn't work well for games where framerate is important. not hogging the processor) until it gets a singleĀ event.Ā  This is much more suited for the game of chess, where the user needs time to ponder their move, anyway.Ā  Replacing my
