pygame.time

pygame.time
pygame module for monitoring time
pygame.time.get_ticks get the time in milliseconds
pygame.time.wait pause the program for an amount of time
pygame.time.delay pause the program for an amount of time
pygame.time.set_timer repeatedly create an event on the event queue
pygame.time.Clock create an object to help track time

Times in pygame are represented in milliseconds (1/1000 seconds). Most platforms have a limited time resolution of around 10 milliseconds. This resolution, in milliseconds, is given in the TIMER_RESOLUTION constant.

pygame.time.get_ticks()
get the time in milliseconds
get_ticks() -> milliseconds

Return the number of millisconds since pygame.init() was called. Before pygame is initialized this will always be 0.

pygame.time.wait()
pause the program for an amount of time
wait(milliseconds) -> time

Will pause for a given number of milliseconds. This function sleeps the process to share the processor with other programs. A program that waits for even a few milliseconds will consume very little processor time. It is slightly less accurate than the pygame.time.delay() function.

This returns the actual number of milliseconds used.

pygame.time.delay()
pause the program for an amount of time
delay(milliseconds) -> time

Will pause for a given number of milliseconds. This function will use the processor (rather than sleeping) in order to make the delay more accurate than pygame.time.wait().

This returns the actual number of milliseconds used.

pygame.time.set_timer()
repeatedly create an event on the event queue
set_timer(eventid, milliseconds) -> None

Set an event type to appear on the event queue every given number of milliseconds. The first event will not appear until the amount of time has passed.

Every event type can have a separate timer attached to it. It is best to use the value between pygame.USEREVENT and pygame.NUMEVENTS.

To disable the timer for an event, set the milliseconds argument to 0.

class pygame.time.Clock
create an object to help track time
Clock() -> Clock
pygame.time.Clock.tick update the clock
pygame.time.Clock.tick_busy_loop update the clock
pygame.time.Clock.get_time time used in the previous tick
pygame.time.Clock.get_rawtime actual time used in the previous tick
pygame.time.Clock.get_fps compute the clock framerate

Creates a new Clock object that can be used to track an amount of time. The clock also provides several functions to help control a game’s framerate.

tick()
update the clock
tick(framerate=0) -> milliseconds
:sg:` -> `

This method should be called once per frame. It will compute how many milliseconds have passed since the previous call.

If you pass the optional framerate argument the function will delay to keep the game running slower than the given ticks per second. This can be used to help limit the runtime speed of a game. By calling Clock.tick(40) once per frame, the program will never run at more than 40 frames per second.

Note that this function uses SDL_Delay function which is not accurate on every platform, but does not use much cpu. Use tick_busy_loop if you want an accurate timer, and don’t mind chewing cpu.

tick_busy_loop()
update the clock
tick_busy_loop(framerate=0) -> milliseconds
:sg:` -> `

This method should be called once per frame. It will compute how many milliseconds have passed since the previous call.

If you pass the optional framerate argument the function will delay to keep the game running slower than the given ticks per second. This can be used to help limit the runtime speed of a game. By calling Clock.tick_busy_loop(40) once per frame, the program will never run at more than 40 frames per second.

Note that this function uses pygame.time.delay()pause the program for an amount of time, which uses lots of cpu in a busy loop to make sure that timing is more acurate.

New in pygame 1.8.0.

get_time()
time used in the previous tick
get_time() -> milliseconds

Returns the parameter passed to the last call to Clock.tick(). It is the number of milliseconds passed between the previous two calls to Pygame.tick().

get_rawtime()
actual time used in the previous tick
get_rawtime() -> milliseconds

Similar to Clock.get_time(), but this does not include any time used while Clock.tick() was delaying to limit the framerate.

get_fps()
compute the clock framerate
get_fps() -> float

Compute your game’s framerate (in frames per second). It is computed by averaging the last ten calls to Clock.tick().
