Re: Is the Hero the Ultimate System?

And caps at 40d6. *boggle*

 

Now how the eff am I going to model that? A massive RKA AVLD Power Defense? A Transform? I know!

 

XDM!

Sory for being late to the Party....

... but for "Overpowered", you might take a look at McWOD (Monty Cook's World of Darkness)

Where an unopposed* LVL 20 mage can, with some forethought disintegrate a 800' radius AoE everywhere on earth, doing to everything in it 20D12 of Fire Damage, 20 D12 of Electrical Damage, 20 D12 of Sonic Damage and 20 D12 of Component (Mana) Damage.

Ok, you need to stock up on Mana for a day (the system won't let you stock more anyway) and you are *EXHAUSTED* afterwards... but Who cares!

The Sonic attack alone is, by their own scale at the "Krakatoa" level..

... Did I forget to mention that it's a VAMPIRIC Attack?

... And that's by rolling a "10" on a D20

Could you model that?

I think that even Galactic Champion would be afraid

Re: Star System Generation (Now at the RIGHT place :/)

Oh, I forgot

I've completed the surface generation...

Granted, it's only basic features (Hydrology, Mountains %, Ice-Cap % and "Desert"%) but it'll give a base for GM to put whatever they want on that bedrock

Right now, the Planet Generation script is working pretty good, I'm only changing the output to have more understandable results.

I might have to re-code some parts, since it's the biggest project I've done in Perl as of yet (I am *NOT* a coder, I have no *real* coding skills, so it's a bit of a mess

As of now, the script is over 1600 lines long but is pretty complete by my standard... I've sumbled upon a Gas SuperGiant with over 40 moons today... with every moons generated unfortunately, since it was a random result, I didn't have the complete result in buffer and couldn't save it oh well, next time!

I'll have to fiddle with the Sector Generation script too, since I've stumble onto a *VERY* basic and stoooopid bug... built into the SH Sector Generation system ... One of those DOH! Moments (Basically, I'm litterally replicating Dice Rolls.. and with +-1D10 for each coordinates, you are missing the ZERO coordinate... DOH!.

I want it to output a distance matrice for the entire sector, a bit like those travel matrices you see in every travel books

Re: Star System Generation (Now at the RIGHT place :/)

@ Cancer

I know about water vapor, I just haven't got around including it yet... I might swap some $ of Methane for Water Vapor, since Methane (CH4) combines with Oxygen (O2) to produce CO2 and Water (H20).

The Density is in "Standard Earth". I'll probably add kg/m3. I will probably add the planet\moon "Volume" too.

As for Hydrogen\Helium, my output is only a sample... I might have tested the output by giving it a short radius ( ex: 1 AU) and putting it in a Blue Zone and keeping the Luminosity not realistic for that scenario I'm presently re-doing the output format so I can see what I generate better (in 2 column, so as to have 1 entire planet\moon on a single screen).

For the Tidal Locking comment, I'm using plain Star Hero stuff... ie: orbits within .5 AU are much more susceptible to be Tidally locked. Granted, I might have to correct the Eccentricity of the planet's orbit after determining that it's tidally locked to the primary (That and Argument of Periapsis and the Logitude of the Ascending Node).

Tidally locked moons are much more common with SH system, but I've put planetary moons further than 30 planetary radii on possible resonnant rotation. It's not perfect, but better than having them all tidally locked. I'd have to correct other orbital parameters for tidally locked moon, same as for planets...

Again, I've used SH's system to generate Ressources. Bigger planets have more chance to generate Heavy Metals and Metals, etc.. further ones tend to generate more volatiles (Gaz Giant any one?)... I've passed on generating complexe life, animals, civilizations etc. That ought to be taken care by the GM, since it can vary much more widely than the rest depending on each GM's setting.

Then again... That script is not even V1.0

@ Thia

Thanks for the Yummy but Frosty welcome

I'll let The Bunneh come along and I'll show him my nice Holy Grail Bunny Slippers...

Dunno, maybe He'll fall in love with them (I'll be sure to wash them afterward tho)

Re: Star System Generation (Now at the RIGHT place :/)

@ SteveZilla

I prefer using Periapsis and Apoapsis just because I'm using the same subroutines for Planets and Moons, but it'll probably change the output... Hell, it's only a case of Delete & Re-type

Presently, Axial Tilt do not have a very big effect in my script, since it mostly has effect on seasons (I'm taking the Earth as an example, with its axial tilt always in the same direction, in regard to the Sun, it only does one full rotation per orbit).

I do *NOT* think I'll be very usefull to go as far as calculating Nutation or other cyclic obliquity changes

As for the Drive-By Repping, I'm still reeling from the impact hit and shivvering from the cold...

But DAMNED, does it taste GOOD!

Re: Star System Generation (Now at the RIGHT place :/)

Thanks for the hints, but I'll stick to the Star Hero generation guidelines

Oh, just some nitpicking Gravity doesn't come from Density, but from Mass... not that the two aren't related tho

Denser objects tends to have more "Pull" due to the fact that most of the mass is "nearer" than less dense objects of same mass (thus being bigger, more mass is farther away from the other mass it's attracted to, giving it less attraction because of the inverse square law...)

Re: Star System Generation (Now at the RIGHT place :/)

What's Left as of now:

The planet's surface:

- Hydrosphere

- Terrain

- Resources

- Maybe put Colonies?

- Asteroids

- Comets

- Space Habitats ?

Then it's cleaning up the code a bit, merging the two scripts into one

Re: Star System Generation (Now at the RIGHT place :/)

Latest Update: Atmosphere is done

Takes into account the following

• Distance from Primary & Planet Mass
  
• Zone (Yellow/Green/Blue/Black)
  
• Albedo (very basic tho)
  
• Greenhouse Effect
  
• Tidal Heating for Moons
  
• Planet Tidally Locked to primary
  
• Planet with very slow rotation
  
• Assume basic life on worlds with temperature "Just Right"

Gives the following:

• Atmospheric Pressure at 0 m. **
  
• Atmospheric Composition for Prebiotic and Biotic atmosphere
  
• Temperature for Periapsis & Apoapsis (to take into account very eccentric orbits)
  
• Temperature at Polar and Equatorial latitude

** I would have calculated the Atmosphere "height", and at what altitude it would equal 1 STD Atmosphere, but lets say that I don't fully how to compute everything and which equations to use...

Re: Star System Generation (Now at the RIGHT place :/)

Hullo Shadowcat...

Yes, I've seen Heaven & Earth some years ago... but I just didn't like it that much... either way, I like the way Star Hero try *HARD* to do realistic systems (ie, it's not just "random" )

As for the generator I'm "Coding" (hacking up, bodging up whaterver the term for the mess I'm typing) I'm in the process of thinking how to code for the planetary atmosphere... I gotta put my mind around it soon, next gaming session's on next sunday ;p

I Just took the w-e off, after 5 days of doing it, I need to see the forest from the trees...

I'll keep you all posted

Re: Star System Generation (Now at the RIGHT place :/)

Unfortunately' date=' I completely lack any skill as to deciphering the scripts you've posted, but, from reading your description, this sounds like it'd be extremely useful. Bravo, I'll continue checking back to see how this turns out.[/quote']

 

Well, those aren't scripts per see... they're the result of them...

Let me walk you through them briefly. The first output is the Star System one... ok, it's *NOT* great, and in need of better layout

 

Basically, it's the coordinates of the star system with brief description of all the stars in the system (I can generate up to 6 stars/system, in a triple binary configuration, that is three pairs of star orbiting each others)

There are infos as the Spectral Class of the star, it's Mass, it's approximate age (needs work tho) the orbits where planets are found (or can be found) the limits for Yellow/Green/Blue/Black zone.

 

The most interesting one is the second... it lists almost everything you might want to know for a planet, starting with it's orbital parameters, then it's physical ones...

This means you know how long it takes the planet to do a complete orbit, a complete rotation, does it have moons and if so, how much, how far are they orbiting and what kind are they (planetary moons as our own, Rings, chunks of rocks...).

 

 

Yeah, maybe it's going overboard for a RPG, but after spending two evening trying to do it by hand and seeing that I had sooooo many to go yet for my campain (and that I *DO* like to have real-looking stuff), well, I decided to automate it all

 

 

And while I'm sure I'm not the first to welcome you to the boards (people 'round here tend to be rather on the ball with the friend-making), I'll go ahead and extend a big welcome anyways.

 

So yeah, welcome!

 

 

Thanks, and btw, you're actually the first... (well, at least the first welcome I've read ;p). I've been lurking for some weeks and from what I've seen, I think I'll like the place

 

Ciao!

Hullo

Fist, Pardon me for the long post... and the post in the wrong board (did not pay attention WHERE I posted the whole thing... /me is stoopid )

Second, being a new "Old" convert (I've played the games when it was only called Champion but rediscovered it a month ago) I'd like to say hi to everyone... and offer a possible gift...

Lessee... I've been preparing a Traveller-esque game for my group and, owning almost everything Traveller, I stumbled upon Traveller Hero... 2 PDF, 5ER, Star Hero and some other purchase later, I've thrown the towel at

designing Star System by Hand (No, I do NOT like those Traveller UPP... anyway, they would not fit IMTU ;p).

Instead... I've cobbled up two nifty Perl script (cobbled as in Bail-wire and Duct Tape, I ain't a computer programmer, tho I dabble a bit in the art).

I'm presently in the process of completing the 2nd script and will merge both thereafter.

Since I'm using Star Hero star/planetary system generation extensively plus a bit of fiddling on my part, if the Powers That Be let me give it all to you,

I'll do it. If not, well, I'd be willing to generate a few fully populated systems and give them to the community...

What I have done so far:

Script 1: Generate a star sector (20 x 20 x 20 LY) with solar system, populating said system with most of the star data available from the book. (I'm NOT generating Brown Dwarfs system as it would not be that usefull)

What's left to do: Clean up the coordinates a tad, clear away "impossible orbits"

Script 2: Takes the Orbit (in AU), Star Mass (in Solar Mass) and the Zone the orbit is in and generate orbital and physical properties of the planets and any moons/asteroid/rings orbiting it.

It can generate every kind of planet and up to approximately 85 moons (I've beefed it up for the Supergiants, since even Jupiter has more moons than the bare system can generate)

What's left to do: Athmosphere, Climate, Life, and Surface properties.

Here are a sample system from the first script and a sample planet from the second...
