Re: Level

Oh, that's a super neat look at dipoles -- I love it! The explanations are also super well done.

Thanks for sharing that!

GSim 3.1.0

Haven't posted many updates here lately, which I should really get better about! (If you want more, I do suggest you join the Discord, or follow my Twitter feed) Anyway, I'm working on big changes to the Gravity Simulator -- with version 3.1.0 almost ready for release. In fact it's out for testing r...

Veloc-t in Space

To celebrate the 10-year anniversary of Velocity Raptor's release (which was, uh, in December, but hey what's time anyway) -- I built a new relativistic toy to play with. Run through the solar system (and beyond) at relativistic speeds in: Veloc-t in Space! https://testtubegames.com/veloctinspace.ht...

Re: Is it possible to change the law's proportionality to mass?

In the full version, you can play with a lot of things (arbitrary force dependence on distance, or even time), but I don't have a way to change the mass dependency. Sorry.

Re: How to simulate an elastic collision?

Oh, there's a setting that will help you out here. There's a Coefficient of Restitution that you can set in the Planets Menu in the lower right. By default it's set to .5 -- but you can set it to 1 for a perfectly elastic collision.

Re: Rotating object code

At a certain point you'll run into issues with the fact this sim is built in 2D -- sorry Uranus. But in general if you want to give objects a rotational speed using code, it'll be input as "rotspeed: 20"... which would be 20 degrees rotation per unit time. There's more detail about the codes here: h...

Re: Rung Kutta 4 in more than 1 dimension of space

That's super cool, I've been wondering about the difference between RK4 and the Euler method in GSim. I know they are off, just as you show in your first post, and the Euler method (can) diverge much more quickly. But on the other hand, I've been wondering about the best way to maybe do a side-by-si...

Re: Pocket Sundial

No, it's not, I'm afraid. That was a fun one, but got outdated on the app store.
