GURPS Space World Building Issue

[Roh]

Oh wow. I had a serious misconception about the effects of a smaller diameter. I never imagined a half the diameter would give you a quarter of the surface area.

I still think I screwed up in a few areas so Myrion's star system generator should be a big help to me. Though so far I've only figured out how to get the example.py going. From some comments in the issues section I think I may possibly me missing out on a lot. lol

Remember that the surface area of a sphere (technically planets are oblate soheroids, but Space doesn't go there and a sphere is close enough) is

A = 4 × pi × r^2

Thus, area is proportional to the square of radius. I believe Space uses diameter for some reason, instead. But D = 2 × r, which gives

A = 4 × pi × (d / 2)^2
A = 4 × pi × (d^2) / 4
A = pi × d^2

So you can see, even with diameter, area is proportional to the square.

I hope it'll help!

Seems to be up and running on my end now :)

Had a misbehaving program block the Starsystem Generator from running after the last reboot...

[Roh]

Hehe I very much appreciate the effort Humabout but the truth is I have trouble with basic math like working anything with fractions and such. I am not bad at all with understanding the pieces to a puzzle I can grasp but my recall is... Ridiculously unreliable.

I'm sure every math rule I ever learned is floating in there somewhere. But for the most part only a very few of them every resurface and usually not enough of them to handle math that is complex. I do okay when enough of the parts are there to intuit what is what but when I need to remember a rule that isn't obvious in the math in front of me? I'm probably hopeless at that point.

lol Myrion I actually just downloaded it from the source and installed python. The first link just showed me a page telling me I had successfully installed tomcat which I havent as I have no idea what it is. ;)

[Myrion]

Yeah, tomcat was misbehaving and blocking the Starsystem Generator... My bad! It's fixed now and the link'll work.

Running it from source is cool too, if you want any help with that, I can try to advise via PM.

However, it seems that something broke on the server, which I'll have to fix tonight.

A suggestion on the generator for improvement:

Allow giving of the random number seed on the starsystem level(The first page) and if given pass on always the same random numbers based on it to the one or more planetary systems generated and use them as random number seeds on those. Thus the same seed would always generate the same resulting system.

Nifty!

The thing I would really like to be able to do is enter star parameters. Specifically spectral class and luminance, because those are the numbers I mostly have for real-world stars, and the others can largely be derived from them.

(While I'm waiting for Jon Zeigler's new system to be ready…)

[Roh]

Hey Myrion I don't suppose you know anyone who tossed together a nifty Species generator too, eh? lol

[Myrion]

Feature requests noted!

I'm actually working on the seed issue, but since we didn't think about it in the very beginning there's some odd problems with it.

Also, I'm glad people like it :)
