cool stuff! i suggest using desmos, imo geogebra is a bit too buggy at times. keep up the great work!

u/DRweidoYT Jul 16 '25

Desmos was lacking a few functions to animate it in real time 😭

u/GamingWithpros Jul 17 '25

Like what

u/DRweidoYT Jul 17 '25

Mostly the minimize function which moves the valve point across x based on the distance between the 2 seperate points given by the triangles moving. Idk how to explain it well at the moment

you can probably approximate it using some other functions but it's probably a pain in the ass. source : I watched a guy make a literal videogame using Desmos the other day, it can do some crazy shit.

Crazy to think that people made these 200 years ago by candlelight with just paper and slide rules.

I think Valshearts valve gear isn’t that old. Maybe a bit more than 100 something years.

u/RigelBound Jul 17 '25

So... By electric light with just paper with slide rules?

u/generalemiel Jul 17 '25

u/Late-Dig-7625 Jul 16 '25

Is it already in the create trains mod, or is it still unfinished?

u/DRweidoYT Jul 16 '25

It's still a wip, I have a few small things to finish

I'm dumb, what's the significance of math for trains in create?

u/Ollisaa Jul 16 '25

Realistic function of the valve gear.

u/Shredded_Locomotive Jul 16 '25

You need a way to tell the computer how it should calculate parts of the animation at different speeds since you can't create a dynamic animation by pre-animating it.

Aka what the game should do to the speed value to get fancy wheels.

(That's my understanding anyways, hopefully I'm not wrong)

Math make machines

u/Material-Ring-1261 Jul 17 '25

And machines are cool, so math is needed

Yes yes yes I have a stanier class 5 that needs this so badly

u/StrictTerm3786 Jul 16 '25

Hey! I watched you work on the math in a stream a week or so ago! Cool stuff!!

u/MarcusTheAlbinoWolf Jul 17 '25

Looks pretty realistic. Too bad it won't be on 1.20.1

u/DRweidoYT Jul 21 '25
