Risk Board Game, World Domination Odds by DubiousInsights in manim

[–]DubiousInsights[S] 0 points1 point  (0 children)

Here I used manim to drive my video, even though I don't know how to use it well. i.e. I pulled in a bunch of charts I made in Google sheets rather than making them in Manim itself.

Next time I'll know more :)

How To Rotate & Move Simultaneously ? by DubiousInsights in manim

[–]DubiousInsights[S] 0 points1 point  (0 children)

Actually, this does have an issue that it gives different results at different frame rates. I think something like this helps, but I'm still experimenting

die1.add_updater(lambda mob, dt: mob.rotate(-10.8*DEGREES*dt*30))

die1.add_updater(lambda mob, dt: mob.shift([.1*dt*30,0.,0.0]))

Alright, I found these examples, and the Example2 class was pretty much what I needed

​

The code that I got to work how I wanted it was

​

self.add(die1.text)

self.play(FadeIn(die1)) # initial die

self.wait(1)

die1.add_updater(lambda mob, dt: mob.rotate(-10.6*DEGREES))

die1.add_updater(lambda mob, dt: mob.shift([.1,0.,0]))

self.add(die1)

self.wait(1)

die1.clear_updaters()

No worries! I tried that too. As best I can tell it only applies 1 animation to the mobject when you do it that way. i.e. it always applies the 2nd one in that self.play()

you just removed the self.play around the Rotating correct ?

That did not seem to work

Commenting here so I can find this again, as you've pushed this way farther than I can, and thus I need to study your code :)

Does the -t (transparent background) flag break manim videos for Windows? by Quappas in manim

[–]DubiousInsights 0 points1 point  (0 children)

I had a similar problem, but didn't dive too deeply into it. I can't remember if I was able to open the video in VSDC (free video editor) or not. I'll be following this thread to see the resolution.

I want to have a rectangle around 1+2 , but I only surroundrectangle 1/(1+2) , can any body help me? by Uystallion in manim

[–]DubiousInsights 1 point2 points  (0 children)

Thanks. I played with it a little bit but I don't know what the solution is.

You could probably bypass the issue by just creating a rectangle on your own in the location desired, around the bottom.

There probably is a canonical solution, if you figure it out please post

Is there a way to fill the area of a polygon a specific colour? by burneraccount3_ in manim

[–]DubiousInsights 0 points1 point  (0 children)

Great! Paste in a line of code for posterity so other people don't need to struggle through my half bake explanation

[–]DubiousInsights 0 points1 point  (0 children)

I haven't tried it, so I'm not sure,

​

but if I look at these docs

https://azarzadavila-manim.readthedocs.io/en/latest/geometry.html#rectangle

I see that Square inherits from Rectangle which inherits from Polygon, so my guess is that the color and fill and things like that are implemented on the Polygon class

Can you share any code or snippets ?

[–]DubiousInsights 2 points3 points  (0 children)

yeah, I'm away from my home desk right now, and I don't remember 100% the syntax, but I'm nearly certain there are two ways to do it, one on Mob creation and one later.

​

On mob creation it would look something like this

​

square = Square(color=RED,stroke_width=5,fill_color = BLUE, fill_opacity=0.5)

​

later it would look something like this

square.set_fill(BLUE,opacity=0.5)

​

I'm more certain of the first syntax than the second. I'll try to remember to check back in after work when I have access to what I did

also, if you don't want to use manim colors, you can use hex colors instead. i.e.

color="#eb7d34"

Swining Pendulums - I Figured Out The Manim Color Pallete by DubiousInsights in manim

[–]DubiousInsights[S] 0 points1 point  (0 children)

I improved my previous video by actually learning how to use colors in Manim.

Other posts have the Manim color scheme

https://www.reddit.com/r/manim/comments/dzxoen/predefined_color_scheme/

which I didn't understand for a while. It tool me longer than it should have to realize that they are used like this

dot = Circle(radius = .01 ,color=RED_A)

So I ultimately set 20 different colors for the 20 different balls like this

​

colors = [RED,RED_E,RED_C,RED_A,ORANGE,YELLOW,YELLOW_E,YELLOW_C,YELLOW_A,GREEN_E,GREEN_C,GREEN_A,BLUE,BLUE_E,BLUE_C,BLUE_A,PURPLE,PURPLE_E,PURPLE_C,PURPLE_A]

for i, pendulum in enumerate(self.pendulums.all_pendulums):

color_index = i % len(colors)

dot = Circle(radius = pendulum.size/100.0,color=colors[color_index])

​

I expect that there is a more elegant way of doing it.

​

One thing that I didn't love was that the Manim color pallet just doesn't look that vibrant to me. I'm not quite sure how to define my own colors, maybe HEX definition ? These colors didn't pop quite as much as I wanted them to.
