Fun Caves replaces the default caves with a dense system of mostly flat (and easier to navigate) caverns, with biomes owing much to caverealms. Once you go underground, you should find everything you need to survive without ever returning to the surface.

Note: This mod is not compatible with mapgen V6, and worlds created with the previous version of fun_caves will NOT work with the new one (no matter how many other mods you add in).

For those who want to add features from the old fun_caves project, take a look at these mods:

Big Trees (killer bees are not included)
Booty (the chests found in dungeons and pyramids)
Elixirs
Fun Tools (chainsaw, flare gun, rope ladders, wall hammer, etc.)

Problems:

- Caves frequently undermine riverbeds and desert sand, causing hilarity if you're foolish enough to dig there. I'm not fixing this one -- I think it's fun.

This is cool, thx. But I got an error message.

Will try to help

Ok, had to replace this "mg" with a. Now it's working. There are caves with sandstone or desert sandstone, but there are light issues. These caves are bright as day

it means fun_cave world i think

(XD i don't know too)

Duane creates a v6 branch. The master is something different.

THX for bugfixing

It's just a place-holder so I could leave some of the world-oriented code in, in case I needed it. (Doesn't look like I will.)

Thanks for your great work. Now I can tinker around with the settings.

I've gone in a new direction with this mod. (See the first post.) It's now a fairly complete underworld environment. There's no surface at all, and anything you'd find there has an equivalent underground. Goblins, spiders, and fungi dominate the caves.

This is really cool!

Duane, your craziness is impressive. Thanks for your great work!

Ah, this is fun_caves.world = true. Nice

That's a really nice idea, but the gobblins are really hard. They spawn from the first second and I died three times in the first 5 minutes. No idea how to survive this. No time to try something.

i will maybe do a game with this, in a long time, when Voxellar will be stable (otherly said: in another life :D)

What I've had to do is immediately run away from the growing areas to some place with salt or hot cobble and then edge back to get some tools. It's a lot easier if you spawn near a cliff and can just pick up their dropped stuff. Ore spawns everywhere, and the nasty goblins (only about half will actually attack you) spawn near it, but you can also get an iron or diamond sword in no time. Once you have that and a stack of mushroom steaks, you're golden.

It's lively, but not terribly difficult once you get used to it.

Edit: It took me about half an hour to come up with all this, starting from scratch. Killed a dozen goblins, several danglers and two big spiders in the process. (One of the danglers gave me a lot of trouble -- it kept jumping up to the ceiling and dropping on me when I didn't expect it.) Not gonna tell you where the bread came from. There's an inexhaustible supply, when you find it.

I've completely removed the massive cave and v6 algorithms, and I'm now using a much denser, more interconnected set of noises. It's no longer possible to give you an idea of how they look, because they take up nearly half the volume of the world... so, here's a random screenshot.

Underground fires can be particularly deadly.

Posted: **Thu May 12, 2016 05:40**

This is cool. Maybe this screenshot might help, but it's still dificult to get an idea

Posted: **Mon May 16, 2016 08:45**

I've added some silicon-based life and biased the ores to spawn in the less pleasant places. Here's a good spot to find mese.

I also fixed the hot/cold nodes so that they properly cause mobs damage and don't require so many abms.

Posted: **Mon May 16, 2016 09:46**

Well don duane. But ores are pretty rare. Had to search a long time to find more than one iron. But then I found more than enough.

And it is difficult to see because of the uniformity of the glowing stones. My eyes are getting tired after a while

Posted: **Mon May 16, 2016 13:09**

On the left side of the screenshot is not a single ore, on the right side is Walhall. And the structure of the cave is better visible. I removed temporarely the decoration.

And I have heavy lags. I was in creative mode and puched a tiny spider once. It took over 10 seconds until the spider dies. I normal mode I was nearly killed by such a tiny spider because I couldn't kill her, but she made damage.

Oh, right, I didn't found any lava yet. And I flew through the caves.

It's a bit strange with the ores. There are area's where I can't find any ores, but there are areas with every kind of ore, even mese blocks and diamonds

The ore is based on the altitudes in the default game. Wherever there's a sharp increase based on altitude normally, there will be a similar increase horizontally here. I like making the ore harder to find. It was too easy before.

There is a lot of lag. Unfortunately, most of it is being caused by the liquid/lighting updates. To be fair, the game wasn't designed for caves in the sky. I haven't had any problem killing anything yet, as long as I'm walking.

The lava is in the hot biomes (where you see hot cobble and coal).

The uniform glow is a bit dull. Maybe I'll make the individual lights brighter and turn off the rest. That would probably help with the lighting lag.

Edit: Yep. That helps a lot. At least until you get into areas with lava and hot cobble. Then it's lag city again.

Beware the deadly ice spider!

...and the ice goblins.

But it's not the same in the defaulf game. Here you have areas with absolutely no ores and then there is a hard cut and you find everything, even Mese and diamonds at +90 and above (see attached screenshot). And it is still easy if you have a little luck. I played an hour and I have a full stack of coal blocks and nearly a full stack of diamonds

Maybe my hardware is not the best, but it was never so hard like yesterday

Found one. Rare

Much better performance. And it also looks much better and there is a need for torches again. Maybe you can add a ramdom brightness to the mushrooms?

Do you have more ideas or do you need inspiration?

Posted: **Tue May 17, 2016 20:52**

Biomes are calculated only in two dimensions, right? I noticed, that there is always the same biome with lichen and the same green moss spot on the same position if I go straight down. Even the shape of the spot is nearly equal. It's like a building with lots of floors with the same carpet. And if you look up you see the same at the ceiling

If you know that there is no need to go down or up to find another biome. Just walk horizontal. Maybe you can use a 3d noise for biomes so that there can other biomes above and below?
