28 | Wire is not defined : Hello everyone, this is my first time using manim, manim-physics and GitHub, i hope that i'm doing every fine and respecting all the rules,
So my issue is that i want to create an animation of a magnetic field streamline being blocked by a metallic shield, and as a starter i wanted to try the code provided in the doc, but when i try to input the Wire example in my visual studio i get this message error :
"Wire" is not defined Pylance (reportUndefinedVariable) [Ln 7, Col 16],
How can i solve this ?
Best regards, | [

27 | Update ```rigid_mechanics.py``` to support Ellipse : When I tried to apply ```make_rigid_body()``` on an ```Ellipse```, it acted weirdly and soon I found its collision box was a circle. When ```get_shape()``` was checking its shape, it fell into the category of ```Circle``` due to the following code:
```Python
if isinstance(mob, Circle):
mob.shape = pymunk.Circle(body=mob.body, radius=mob.radius)
```
Adding an if statement solved this bug:
```Python
if isinstance(mob, Ellipse):
vertices = [(a, b) for a, b, c in mob.get_start_anchors() - mob.get_center()]
mob.shape = pymunk.Poly(mob.body, vertices)
elif isinstance(mob, Circle):
mob.shape = pymunk.Circle(body=mob.body, radius=mob.radius)
``` | [

26 | Refactor. Breaking Changes. : ### Changes include:
- Renamed `src` to `manim_physics`
- Structured the files into categories:
- electrostatics and magnetostatics -> electromagnetism
- rigid_mechanics and pendulum -> rigid_mechanics
- lenses, rays -> optics
- more documentation(?)
- better tests (run pytest)
- implement GH CI(?) | [] |
21 | Added `**kwargs` to `get_force_on_charge` method : The `Vector` object returned can then be instanciated properly. | [] |
20 | Manim-physics is not longer working (with the last version of manim)? : I tried one of the examples and get an error. It was previously working (althought it´s been a long time since I ran it) | [

19 | VGroups as whole rigid bodies : Fixes #18 | [] |
18 | Make `SpaceScene.make_rigid_body` not take children of `VGroups` : From discord user Naw Sai: [SVGMobjects don't work as rigid bodies.](https://discord.com/channels/581738731934056449/875659130667425853/955458158300659793)
This is because the function `SpaceScene.make_rigid_body` takes the whole family of the mobject and applies the rigid property; which explains the explosion, as overlap of rigid bodies are considered high powered collisions.
### Suggested Changes
I think a good approach would be to make the function disregard families; if the children are intended to be rigid, then an unpacking operator should be used.
Before:
```py
a = VGroup(Circle(), Square().shift(UP*2))
self.make_rigid_body(a)
```
After:
```py
a = VGroup(Circle(), Square().shift(UP*2))
self.make_rigid_body(*a)

17 | Fix lensing module : - The lensing module is fixed, taking into account how the `shapely` package lists the intersections.
- Poetry files are updated to avoid`scipy` install error in Python 3.10
- formatting with black | [] |
16 | OpenGL import compatibility with recent releases : Added try except block to handle `ModuleNotFoundError` due to manim v0.15.0's file structure. | [] |
14 | Add lensing module : ## New lensing module
Showcases refraction happening in lenses.
Example Scene:
```py
class RayExampleScene(Scene):
def construct(self):
lens_style = {"fill_opacity": 0.5, "color": BLUE}
a = Lens(-100, 1, **lens_style).shift(LEFT)
a2 = Lens(100, 1, **lens_style).shift(RIGHT)
b = [
Ray(LEFT * 5 + UP * i, RIGHT, 8, [a, a2], color=RED)

self.add(a, a2, *b)

13 | Restructure, documentation, and general updates : Changes include:
## Documentation
The plan is to host a readthedocs.org documentation. But these changes are important prior to that.
## Magnetism Rework
Fused CurrentMagneticField and BarMagneticField into MagneticField.
## Fixed 3D Waves
The parametric surfaces were deprecated and had deprecated parameters.
## Dependency
Added new dependency for a new feature, ray tracing. Another PR will showcase that. | [] |
12 | Added `GRAVITY` attribute to `SpaceScene` : Added `GRAVITY` class method to `SpaceScene`.
