Clock provides you with a convenient way to schedule jobs at set time intervals and is preferred over sleep(), which would block the kivy event loop. These intervals can be set relative to the OpenGL drawing instructions, before or after. The Clock also provides you with a way to create triggered events that are grouped together and called only once before the next frame.

  • schedule_interval()

  • unschedule()
