Element Management

The Element management functions of Scene object is to manage the Mobject objects of Scene object. The Element management functions are

• def add(self, *mobjects)
• def remove(self, *mobjects)
• def add_mobjects_among(self, values)
• def add_foreground_mobjects(self, *mobjects)
• def add_foreground_mobject(self, mobject)
• def remove_foreground_mobjects(self, *to_remove)
• def remove_foreground_mobject(self, mobject)
• def clear(self)

def Remove_foreground_mobjects(self, *mobjects)

Remove the priority of one or more Mobject objects by reconstructing the specified Mobject from the priority casting list of Scene object back into the casting list of Scene object according to the existing position or layer in the combined list. In other words, the priority of specified Mobjects are stoped by moving from the priority casting list to the foreground of the casting list.last updated 28Dec2019

Example of Scene.remove_foreground_mobjects.

Code Scene.remove_foreground_mobjects

# folder/file: tut/manim_scene_remove_foreground_mobjects_001a.py

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

class manim_scene_remove_foreground_mobjects_001a(Scene):
    def construct(self):
        temp=Square()
        temp1=Circle(stroke_width=10)
        temp2=Square(color="#FFFF00",stroke_width=10,side_length=1.8)
        temp3=Square(fill_opacity=1)
        temp4=Square(color="#22FF00",fill_opacity=1,side_length=1.5)
        temp5=Circle(color="#22FF00",radius=1.1,stroke_width=10)
        self.add(temp)
        self.add_foreground_mobjects(temp2,temp1)
        self.add(temp3)
        self.remove_foreground_mobjects(temp1,temp)
        self.add(temp4,temp5)

Output Scene.remove_foreground_mobjects

def Remove_foreground_mobject(self, mobject)

Same function as remove_foreground_mobjects, but remove only one Mobject object from the priority casting list of Scene object back into the casting list.last updated 28Dec2019

        self.remove_foreground_mobject(temp1)
        self.remove_foreground_mobject(temp)
        self.add(temp4,temp5)

Output Scene.remove_foreground_mobject

def clear(self)

Clear all Mobject objects in both the priority casting list and casting list of Scene object. In other words, all element in both the priority casting list and casting list of Scene object are removed.last updated 28Dec2019
