With low gravity and jet pack this seems like a lot of fun.

[prof-turbo]

It doesn't need worldedit ?
Nice :D

[qwertymine3]

It doesn't need worldedit ?

Nope, this mod is completely stand-alone. :D

It only depends on the mods containing the nodes that the planetoids generate from. By default this is only the default mod.

[paramat]

This looks cute.

[rubberduck]

and very very funny too.

[qwertymine3]

Update!

Added some more planet-types
Added some basic surface population for non-solid nodes - e.g. flowers
Added new dependency flowers

P.S. no-one seems to have noticed the extra geometry settings, guess I'll have to post screenshots :(

[rubenwardy]

This looks cool.

[benrob0329]

This would make a neat multiplayer server!

[prof-turbo]

Is there a parameter to increase or dicrease space between planets?
I think this wold make a cool kind of skyblock server :D

[Xanthin]

Oh, I have to try that as soon as possible. With the Dragon Hunters world back in my mind. :)

Increase the value of planet_size.scale in settings.lua - default is 3

Spoiler

There are two main parameters in settings.lua which you are interested in.

• The point_distribution table - an indirect way to do it
• planet_size.scale - the 'correct' way

Quick background:
The mod splits the world into cubic sectors and generates points in these sectors

point_distribution is a table used to determine how many points are generated in each sector. The values are relative probabilities and the indexes are the number of points to be generated. Default is used if a value can't be found for any reason.
-Reduce the size of the numbers for higher indexes to reduce the number of planets

planet_size.scale The size of a sector is the maximum planet radius multiplied by this number in each direction.
-increase this value to increase the distance between planets

[qwertymine3]

Update!

Re-organised settings.lua into 3 files.
settings.lua for main settings
planets.lua for planet definitions
populator.lua for basic populator definitions

nice, you could add perlin noise planets (see https://github.com/HybridDog/vector_ext ... #L406-L488), the only problem is that it may take too much memory because all the values need to be stored because minetest's perlin noise is a bit buggy (values exceeding [-1;1])
you would also reduce the maximum planet's radians at the mapchunk corners to 16

maybe you can help me with a mistake l don't find
l tried to make a "net noise", but somehow the points outside the chunk corners differ in each chunk

I'm not sure if I will do that in this mod - maybe in a separate but similar mod.
It shouldn't use much more memory than a single perlin mapgen though.

Can you explain why I would have to limit the radius to 16 though?

[Hybrid Dog]

If you use that code, perlin noise values are calculated for a sphere, then those values get normalized. Normalization only works if every value is known. You can of course use bigger radians at chunk corners, but the code l linked to doesn't support it without editing it because that currently uses math.random.

You add it and make it configurable with a setting.

The only thing (other than the undefined output order from using pairs - but that shouldn't matter), that I could see that could change with the chunk is the seed, if you've accidentally used the chunk seed rather than the map seed.

You're also not guaranteed to generate any points below minp, but IDK if that would affect the test you were doing

[qwertymine3]

Hotfix!

Fixed occasional glitches/collisions in mapgen at sector boundries

[kaadmy]

This might be very interesting in multiplayer with the planetoids close enough together so you can jump between them, and low gravity ;)

thanks a lot, the lines seem to at least direct to the joints everywhere
to make it work right l guess l also need to add that number to a specific s…

l thought about using the "net" as frame for buildings, which become generated there.
l would need to add a new sort of building because l used the hut ones already as swamp huts.

[Don]

This looks awesome. Great work!

[qwertymine3]

Update!

Added Perlin noise planetoid generation mode.
Added documentation to settings.

[cd2]

Wow!
That looks really cool!

[qwertymine3]

Update!

Nothing much, just added a mod.conf and made the mapgen automatically set the mapgen to singlenode.
Not yet added the new minetest 0.4.15 content, but will do at some point.
