11 months ago Realistically this should have been two bugs, but I've been running into a lot of issues with LinearTransformationScene, and I thought it might be easier to create a master-list of sorts.

11 months ago It's fine to have issues with multiple things as long as you do the checklist notation! so that we can keep track of it!

11 months ago Cool, do the checkmarks I have now work? Or should I make an official to-do list for this issue

Description of bug / unexpected behavior
There are a variety of bugs in the LinearTransformationScene. Of note:
ValueError: operands could not be broadcast together with shapes (<coordinate pair>) (<coordinate pair>)Todo: test with other text-based Mobjects (number, decimal, etc)self.wait()if not the final statement in the scene causes an error:TypeError: All submobjects must be of type VMobjectExpected behavior
self.wait()should not cause an error in the middle of the scene.How to reproduce the issue
Code for reproducing the problem
* Text, Tex, & MathTex Mobjects fail upon animation: ```py class LinearTransformationSceneExample(LinearTransformationScene): def __init__(self, **kwargs): LinearTransformationScene.__init__( self, show_coordinates=True, leave_ghost_vectors=True, *kwargs ) def construct(self): text = Text("Hello world") tex = Tex(r"\LaTeX") math_tex = MathTex(r"\pi x_{1} x_{2}") group = VGroup(text, tex, math_tex).arrange(DOWN) self.play(Write(group)) # <---- FAILS HERE # Note that instead of playing, `self.add(group)` works fine. matrix = [[1, 1], [0, 1]] self.apply_matrix(matrix) self.wait() ``` * Calling `self.wait()` before the end of the scene fails: ```py class LinearTransformationSceneExample(LinearTransformationScene): def __init__(self, **kwargs): LinearTransformationScene.__init__( self, show_coordinates=True, leave_ghost_vectors=True, *kwargs ) def construct(self): circle = Circle().set_fill(YELLOW, opacity=0.7) self.play(Create(circle)) self.wait(2) matrix = [[1, 1], [0, 1]] self.apply_matrix(matrix) self.wait() ```Additional media files
... there are no files to paste. it fails to render. that's what this bug report is about.

Text bugs: calling
self.add()does not error Wait bugs: callingself.wait()as the very last action in the scene does not error.
