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 That was a fun one, but got outdated on the app store.

Re: When is the "new" Agent Higgs going to be out?

It's coming. But that's not terribly specific, is it. Hmmm. Right now I'm doing some playtesting on the new version, set to be released on web/mobile/pc/mac in probably a couple months. If you'd like to help test it, or see the latest, I'd suggest you join the Discord channel (link on the main page)...

Re: Online Version does not open on Macbook Air

Alright, I've got a beta built that hopefully fixes this.

It's here, if anyone who's had the bug wants to test it out: https://testtubegames.com/gravity_beta.html

Edit: Now the new version is posted on the main gsim page.

Re: Online Version does not open on Macbook Air

Oh excellent - thanks, that helped. Looks like it's a known issue in Unity that does in fact have a patch.

I'll post here once I've gotten it fixed.

Re: Automatically pause when loading from code?

Ah, interesting. It looks like the behavior is different depending on which way you access the load panel. If you go out to the main menu, as you describe, it always starts playing automatically. The way you'd want to do it is use the save (& load) button in the upper-left menu. That will preserve t...

Re: Automatically pause when loading from code?

There's not a line of code, but (in theory) -- if the sim is paused before you open the save/load panel, it'll remain paused when you load a setup.
