Re: GSim 0.32.01 - 0.32.06

0.32.09

By popular request, now you can use time as a variable in the force law. Just use 't' in you equation.

Re: Can time to be introduced in gravity function?

That'll be one soul, please.

(Version 0.32.9 is up on Humble, use a lower-case 't' to write time into the force law)

Swing Explorer

How does swinging work? Like - pumping your legs... how does that get you swinging higher and higher? ... It's simple enough to actually go to a playground and swing - but when you start going into conservation of energy/momentum/angular momentum, this topic can get a bit (a lot) confusing. For inst...

Re: "I'm stuck on Level..."

The wording on the level is a bit ambiguous -- what you're trying to do is get the color of all the keys to match each other. So you'll want to blue-shift the redder key, and red-shift the bluer key.

You don't need to bump into the gate, it'll open up whenever the keys match.

Black Hole Explorer

The distortion of space (and especially time) around black holes is fascinating to me - so I made an experimental little sim, to see if I could recreate that. https://testtubegames.com/ShareBox/blackhole/ Move around, explore the space, and add (or shoot, if you're moving) Beacons to see how clocks ...

Re: The Fittest

I have no problem of you posting about how the dna works -- In fact, there was this comment posted on the sim's page that makes a pretty exhaustive attempt to decode the code. If you wanna know how it works... Stuart Lyall posted this - I haven't checked it, but a quick skim of it looks about right ...

Re: Trouble with saving/loading files.

Let's see if I can help out here... Starting with the (easier) second question - you set the name by adding an "n:" argument to the settings, like such: _settings(gravity: r^(-2), x: 37.07583, y: -15.83333, n:The Astroman System); For your first problem, I'm wondering if the simulation might be paus...
