Time Management

The time management functions of Scene object is to manipulation those time related activities of Scene object. The time management functions are

• def wait(self, duration=DEFAULT_WAIT_TIME, stop_condition=None)
• def play(self, *args, **kwargs)
• def wait_until(self, stop_condition, max_time=60)
• def increment_time(self, d_time)
• def compile_play_args_to_animation_list(self, *args, **kwargs)
• def update_skipping_status(self)
• def begin_animations(self, animations)
• def progress_through_animations(self, animations)
• def finish_animations(self, animations)
• def idle_stream(self)
• def force_skipping(self)
• def revert_to_original_skipping_status(self)
• def add_frames(self, *frames)
• def show_frame(self)

def wait(self, duration=DEFAULT_WAIT_TIME, stop_condition=None)

In general, wait function is used to define a time frame in Scene object.28Dec2019

Example Scene.wait

Example of Scene.wait.

Code Scene.wait

# folder/file: tut/manim_scene_wait_001a.py

from manimlib.scene.scene import Scene
from manimlib.mobject.geometry import Circle
from manimlib.mobject.geometry import Square
from manimlib.mobject.mobject import Mobject

class manim_scene_wait_001a(Scene): 
    def construct(self): 
        temp1=Circle(stroke_width=10,radius=2.5)
        temp2=Square(color="#FFFFFF",side_length=4)
        temp3=Circle(radius=2.2,color="#FF0000",stroke_width=10)
        temp4=Circle(color="#FFFF00",radius=1.75)
        temp5=Square(color="#FFFF00",side_length=2.25)
        temp6=Square(fill_opacity=1,side_length=5.25)
        dummy=Mobject().add(temp4,temp5)
        self.add_foreground_mobjects(temp6)
        self.wait(2)
        self.add(temp1,temp2,temp3,dummy)
        self.wait(2)
        self.remove(temp6)
        self.wait(2)
        self.remove(temp1,temp5,temp3)
        self.wait(2)

Output Scene.wait

def play(self, *args, **kwargs)

In general, play function is used to define a action time frame in Scene object.05Jan2020

        self.play(FadeOut(dummy2),run_time=2)

Output Scene.play
