[Mod] Fun Caves [fun_caves]

[burli]

I guess I found the reason for the shadows and other issues with the v6 lua cavegen. I replaced "air" with "default:cobble" for large caves and "default:wood" for normal caves.

Normal caves "grow" sometimes into forests


Huge caves are floating in the air. Inside the huge caves are small caves


And they are eveywhere


An interesting fact is, that the large caves always spawn at specific heights

Ok, but why would that cause shadows when you're only placing air?

[duane]

a crystal cave?!?cool!

The salt blocks are dim light sources in caverealms, which makes them look pretty, but it spoils the surprise when you're moving toward another lighted area in the distance and you hit a (nearly) invisible wall. In some places, it's a bit like a mirror maze.

I don't know why, but I noticed something similar with the original intersecting mod. There is just a hard limit at 48. Sometimes I found a shadow right next to a hole. If you fly above the shadow you see, that the wield hand gets darker and normal again around 48.


I also think that there must be normal caves in the air. I can see them in the water, they are inside the large caves and they "grow" along other nodes like trees. But for whatever reason air is not replaced by the small caves. It is really strange.

Another thing I noticed is, that h1 is always 1. Are you sure that vector.add can add 4 values?

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

vector.add(v, x)`: returns a vector

[burli]

Ok, this looks better. No flying large caves, but still shadows, caves still eat up plants and caves under water

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

local p1 = vector.add(orpi, vector.add(veci, vector.add(this.of, this.rs / 2)))
local p2 = vector.add(orpi, vector.add(this.of, this.rs / 2)

This one is a special one. It does not collapse



Is it possible that lua mapgens are executed AFTER the decoration? This would explain the destroyed plants

[duane]

It won't unless you update liquids (which causes lag, sadly).

They are.

Your wield hand darkens when you fly into an ungenerated chunk. It brightens once the chunk generates (even if it's nothing but air).

I also think that there must be normal caves in the air. I can see them in the water, they are inside the large caves and they "grow" along other nodes like trees. But for whatever reason air is not replaced by the small caves. It is really strange.

That probably has to do with the fact that large caves are not generated by noise, so the game has no way to tell that a stone roof won't be generated over one at a chunk border. With the smaller, noise-generated caves, there's an easy way to see where they extend into the next chunk.

Another thing I noticed is, that h1 is always 1. Are you sure that vector.add can add 4 values?

I am not. It does in most languages, but lua is special.

I started to miss the surface world, so I added it back in. It should work with any mapgen that produces a heightmap.

I like your work and I think about to use it for something new

[duane]

Wasting time, watching a bunch of goblins dig a new quarry. It's kind of like having an ant farm.

I have a texture bug. Mob Textures are not loaded with your latest version

[burli]

I noticed that your top dirt block is a full grass block. Do you use a mod for this? I asked for this feature a few weeks ago, but did not find a satisfying solution

Which ones? It shouldn't matter much, since the affected mobs will die out and be replaced.

There are a number of texture packs (e.g. PixelBox) that have side grass. I use my own compilation, but I've borrowed from so many sources, that I can't post it for fear of leaving the credits out.

I was attacked by naked spiders. I add mobs mod, but not mobs_monsters. I expected, that you just need the api, but you removed some textures. So I had to add mobs_monsters to get the textures

Or are you using an older mobs mod befor it was splitted?

[duane]

I added some plants and coral, using some of my textures from valleys_c, to liven up the surface. This time I'm not using any water abms.

[azekill_DIABLO]

stupid question : inyour 1st post u say there's no surface... but why there is a river, grass and sun??!?!

ok thx ;)

See https://forum.minetest.net/viewtopic.php?p=218419#p218419

I think your heightmap checks may be failing, large caves should not be generated high in the air. The dark air of overgenerated large caves can cause lighiting bugs.

That's probably true. I've already taken all the large cave code out of the mod. Burli's using the original code I cobbled together from the C source and never maintained.

[duane]

Deserts were not much fun, so I added small rocks (which can be made into cobble) and a recipe to turn dry shrubs into sticks. I've also added hunger, so I had to add some food to this harsh terrain. Bon apetite.



The code is now faster, but it still develops a lot of lag at times. I think some of that is due to the large number of creatures I have available.

Hm, I add a counter. I just waked on the surface the first ingame day and in this time over 40 mobs are spawned. But it is also possible to get up to over 100. I don't know if they are all active

And I noticed that I get demage without any mob around. Even if I fly in the air I got damage. Is that by intention?

[Edit] you added hunger. Just read it now, sorry

And if I punch a mob the game craches

That's an old error. Are you using the latest mobs redo?

[burli]

A few days old. But I can update again if there was an update shortly

[duane]

That's definitely not the version I've got, which has the mobs_redo directory and different code. I got mine from https://github.com/tenplus1/mobs_redo.

No idea what happens. My version was maybe two weeks old and I could play two days ago with this mod.

I just downloaded the new version of fun_caves and replaced the old one. Then I got the error

[duane]

I'm working on hidden fortresses, underground. They'll be mazes full of nasty creatures with some kind of trophy hidden inside. Collect the set and you win a no-prize. (They won't actually be lit. I took the shots in debug mode.)

[azekill_DIABLO]

+1

[duane]

Mobs that spawn in fortresses are now tougher than their free-roaming cousins -- a little tougher up top -- at the bottom... expect pain. This should work for any mobs_redo mob, as long as you add a register_spawn line with the "fortress" group set (so they spawn there at all). It won't affect mobs that wander in from above.

Edit: A lesser goblin just killed me in two hits. I may have to look into armor mods.
