There used to be legends. Legends of places below the previously conceived bottom of the Overworld. Some said that the Bedrock was the end of the line, while others said that it was just a barrier protecting us from what lies below. -DesinitDraco

Public Modpack Rules (you have to follow these if you put my mod into your modpack)

Private modpack rules are the same, except you don't need to PM me if you aren't making money off it (though it would still be nice if it's used by a lot of people on a large server).

Modpack suggestions (you don't have to follow these, but in most cases it would improve the gameplay, but if you want to, ignore these)

Modpack rules only apply if you actually distribute the pack with Deeper Caves in it. Just clarifying in case I accidentally scared anyone off there by making them think these rules apply just because you are running Deeper Caves with other mods or adding it to your personal copy of a modpack you play.

This mod will be genius. If you need help with textures, contact me.

Thanks! However, the users in the suggestion thread already made all the textures I'd have trouble making up to the Bedrock Plains level (minus Compressed Lapis, but I think I'll think of a way to do that). I'll ask you if I have texture troubles for a later update.

Looks nice, I would guess 1.7.10 since that's what the first mod was made for, but what version? I want to test it.

Yes, it's 1.7.10, because that's what I'm used to working with. You can try it if you really want to, but Beware the Bugs! If you want to know what said bugs are, look at the issues page of the GitHub: https://github.com/Valiec/DeeperCaves/issues

I know how to fix the first bug (less caves with height) that is because caves have an exponential distribution that gets rarer as you go up, due to nesting two random calls in the form of random.nextInt(random.nextInt(120) + 8); the first random() returns a number between 0 and 119, averaging 59.5, which is then passed to a second random() after adding 8, which in turn halves the average again, for an average of 33.25. That is, using the default vanilla distribution places half of all caves below y=33.25 with the greatest concentration between 0-7. You can make them evenly distributed by simply removing one of the randoms; i.e. random.nextInt(127) will give the same range (0-126).

Note also that if you do this you'll probably want to increase their size and/or frequency (the size is set by three nested random calls, meaning the average is only 1/8 with a highly nonlinear distribution weighted towards 0; the default size is 40 (0-39) in 1.6.4 and 15 (0-14) in 1.7, resulting in averages of 4.875 and 1.75); the frequency is set by a random call that sets the size to 0 if it is nonzero, 15 in 1.6.4 and 7 in 1.7, meaning 1/15 and 1/7 of chunks will have an attempted cave system, assuming the size wasn't already 0, as it is so often that in 1.6.4 the actual chance of a cave system is about 1/20.

This results in an average of 0.325 caves per chunk in 1.6.4 and 0.25 caves per chunk in 1.7, with 1.7 having a much more uniform distribution of caves (the size affects their clustering while chance affects their general frequency; for example, setting size to 80 and chance to 30, resulting in the same number of caves overall as 1.6.4, will make caves much more concentrated in cave systems with much larger open areas).

Basically, if you increased the range to the full 0-255 height you'd want to make caves about 8 times more common to get the same density as a normal world has in the lower 33-odd layers, perhaps even omit the lines that set the chance per chunk.

Also, some other values you may want to change:

The following code controls the maximum width of a cave:

float var19 = this.rand.nextFloat() * 2.0F + this.rand.nextFloat();

if (this.rand.nextInt(10) == 0)
{
    var19 *= this.rand.nextFloat() * this.rand.nextFloat() * 3.0F + 1.0F;
}

This results in an average maximum width of (1.5 + 1.5*) * 2 = 6 blocks, since var19 averages 1.5 with a peaked distribution (similar to the distribution of lapis). There is also an addition 1/10 chance of an additional multiplier being applied to this value, averaging 1.75 as each nextFloat() averages 0.5 and they are multiplied together (basically the same result as nesting nextInt() as with the size and vertical distribution).

*The second 1.5 comes from the actual method that generates a cave, which adds 1.5 to a width value that varies from 0 to the maximum using a sine function; thus the narrowest caves are 3 blocks wide.

Here is a chart showing the distributions in the size of cave systems and width of caves (see blue line, using the defaults for vanilla 1.6.4; note that I included the extra caves associated with circular rooms thus the largest size was greater than expected from the range of 0-39 noted above):

Another thing that can be changed is the length of caves, which is set by the following code in the method that actually generates caves:

int var26 = this.range * 16 - 16;
p_151541_16_ = var26 - var25.nextInt(var26 / 4);

"this.range" is set to 8 chunks by default, which means caves get up to 7 chunks (112 blocks) long. Note that if you increase the range it will significantly increase the resources required since the code basically checks a range of +/- this.range from the current chunk so it can follow any caves that generate in that area, which is how it knows if a cave intersects the current chunk, thus 8 chunks means it checks 17x17, 289 chunks. However, you can separate them and since caves aren't straight you can make them much longer than the range without getting cut-off caves; for example, in TheMasterCaver's World I increased the range to 12 chunks (I copied over the range-checking code from MapGenBase and combined them, thus my MapGenCaves is its own single class) and have caves and ravines up to 336 blocks long, triple their normal length (suggesting a range of (336 + 16) / 16 = 22 chunks) and don't get cut-off caves/ravines (I also modified the "curviness" so longer ones, particularly ravines, are curvier).

There is also more that you can change; for example, these are screenshots of a mod I made to change caves using Customized (if with issues due to MCP reobfuscating the code improperly):

I just tested out the mod... and I noticed something odd... Compressed lapis ore block drops... ink sacs? That's funny. I understand it's a WIP, but still. I just thought i'd point that out, as I find it funny.

Actually, I'll turn this post into a little bug tracker of bugs I found... If you don't mind.

That's all for now, I know this is a WIP mod in it's extremely early stages, so no rush. Also, I would of done more tests in the layers, but for whatever reason my FPS drops significantly to unplayable states when in them. Even on peaceful and on lowest settings. Although once I reach the over-world, i'm usually fine......

Bugs marked with a + means it's most likely a bug
Bugs marked with a = means it's most likely intentional

+Compressed Lapis ore Block drops inc sacs
+Portals are breakable
+Potion effects reset when entering a new layer
+When player is on fire, it is removed when going through layers
+Crystal layer crashes
+Bedrock plains doesn't use fragmented bedrock
=No textures for some Compressed ores (I know you're working on it, but I rather list everything I find)
+Silk touch tools can retrieve portal blocks
=Items bounce on portals and cannot use them
+Jumping onto a return portal while in the overworld will cause glitching, preventing moving and gives major lag
=Other entities seem to ignore portals
=tile.returnPortal.name will return you to the over world, even when multiple layers deep
+Entities treat portal blocks as full blocks and try to use it when pathfinding, resulting in them jumping in and out of it

Thanks! Here's my progress:


Also, could someone explain what is going on with issues #1 and #5 here?

Edit: The fixes for the issues DrWeegee123 found are in the compiled download now.

AWESOME!!!!
IT'S BECOMING TRUE!!!

Also, could someone explain what is going on with issues #1 and #5 here?

The issue with the lava falls may be similar to the cave height issue; they are also generated with a nonuniform distribution that places most of them near the bottom of the map, and it appears that instead of using a custom biome decorator you are just using the vanilla one (WorldProviderDrop uses BiomeGenBase.forest as the biome, the chunk provider appears to call the usual biome decorator).

This is the code in BiomeDecorator that generates lava springs; note also that far less than 20 actually generate since the point selected must be just in the wall of a cave, surrounded by stone below and on three sides with air on the fourth side, plus many attempt to generate below y=11 (the calculated average for the values shown is around y=35 for the 50/50 point):

for (var3 = 0; var3 < 20; ++var3)
{
    var4 = this.chunk_X + this.randomGenerator.nextInt(16) + 8;
    var5 = this.randomGenerator.nextInt(this.randomGenerator.nextInt(this.randomGenerator.nextInt(240) + 8) + 8);
    var6 = this.chunk_Z + this.randomGenerator.nextInt(16) + 8;
    (new WorldGenLiquids(Blocks.flowing_lava)).generate(this.currentWorld, this.randomGenerator, var4, var5, var6);
}

Essentially, the solution is similar to the cave height issue; you can add this to the chunk provider after the call to BiomeDecorator in the populate method (this is the last thing to be placed in BiomeDecorator) and it will generate additional lava springs in addition to those normally generated. Note also that the blocks they generate in must be stone so keep that in mind if you use custom blocks in place of ordinary stone; you could also use your own version of WorldGenLiquids, adding a parameter for the block to generate in, assuming that Forge didn't add one itself.

I also thought that I'd point out that a similar situation occurs for lava lakes (generated in the chunk provider), plus when they generate above y=62 (Overworld sea level) there is only a 1/10 chance of generating, so if you want them to be more common higher up you can change this as well, plus the 1/8 chance they have of generating in a chunk (by comparison, water lakes generate with a uniform distribution over 256 layers and a 1/4 chance; this also explains the chance of 80 (8 * 10) given in Customized for lava lake frequency as they are referring to surface lakes).

Very cool mod. I wish you all the luck. I'm anxious to try it out as soon as some of the bugs are worked out.

Quote from lolcreeper200»

So I decided to try the mod for myself.

First, I did a "dig down" and soon came across a portal which leads to the "Drop Level." After a couple of minutes for loading, the level loaded up and I can safely say that yes, it does work. However, coming back through one of the portals was a different story. It loaded almost immediately, but for some reason I was completely stuck, similar to how you suffocate in sand, and most likely in a different location than where I came down.

I have some pics below, one of which being a "cave chicken" in the Drop Level, which was kind of hilarious.

Also, quick question, can these portals spawn in pre-existing chunks that were loaded before the mod was installed and/or in an older version?

ye, i bet ya the creator doesnt save last world location xyz coords in the player files. it is a good thing to add NBT tags for "Dimension name: x y z" so that onEnterPortal to (say the deep) "TheDeep: lastCoordX lastCoordY lastCoordZ"

this is just a very rough addition but maybe adding sky layer dimensions as well?

This came from my one post on the original suggestion.

As for items, idk wth to add so maybe you could smooth it out. All i had was the idea of also seeing sky layers too.

As well, (if you want) you dont need portals. you can check their YCoord

if(@yChoord == DIM.World(yCoord(0))

tp player DIM.World

PS: feel free to tweak my idea in any way shape or form.

This is great and all!!! but where is the love in the sky :)?

i'd love to see more done with sky levels.



Here is just some of my suggestions:



So ye, you start with the regular surface layer:


This layer consists of Below sea level, sea level, and above sea level

Pretty straight forward for the ground.



But wait:

Surface level:


The next level apart of the surface level (sub level)
is the hills level. Still pretty explanatory.
The next level up is still apart of the surface level (sub level)
and this is the mountainous level. This consists of tall, jagged mountains that stretch
high and reaching peaks that would normally be hard to traverse.
At this point, you would be way above the clouds.

Mountains will contain methods of getting to the stratosphere:

Stratosphere:


The stratosphere consists of ethereal, tangible clouds that can be mined. Up here, there isn't much other than clouds
but you can get air essence from the clouds to use in some way.
The stratosphere is a dangerous place because it is easy to fall from this height.

After the stratosphere comes the Thermosphere:



Thermosphere:


The Thermosphere is a place that verges to the exosphere.
Up here, gravity is reduced by some amount and your jumps let you jump higher.
The Thermosphere consists of patches of floating tangible cloud dirt and stone.
These patches aren't much but is considerably more than the clouds down in the Stratosphere.
It is also considerably snowy up here and there is ice and snow patches.

After the verge from Thermosphere, you then make your way to the Exosphere.

Exosphere:


The Exosphere is a whole bunch of chaos. Up here, you jump higher than before.
The Exosphere consists of floating islands made of star dust and meteor ore. This area
has a lot of floating land in which you can explore. There are Temples up here. There are also
cherubs and frozen angels up here. Other mobs such as sky whales exist up here too. There are
a few mystical ores up here and multiple other blocks (feel free to add onto my ideas). This land also
has ice and is weathered with snow. Snow up here starts to hurt if you are in it for too long.

After the Exosphere comes space.

Space:


This is the only level where fly is enabled, leaving this layer will cause you to fall to your doom.
Space consists of solid meteors and stars where you can collect sun stone

After space comes the final level, the furthest reaches:

The furthest reaches:


After a while of space travel and going up some more, you make your way to the furthest reaches.
Here, gravity is fine. The terrain consists of ethereal clouds and a high density of floating islands made of hallowed ground and
holy stone. Mobs such as angels, statues, unicorns, bunnies, winged pigs, and Hallowed guardian can be found up here. Holy ore can
be used to make excalibur. Other ores like star fragments can be used to make other neat things. You can also find the heavenly vast temple
up here that can wield some sick loot. The temple also has an egg in the middle of it u can use to summon and kill the sky dragon (or maybe a god). after killing the dragon or god, a teleportation will be set up that u can use to get back down to the surface. Also you can make Hermes Boots with the hallowed ingots and golden feathers which will let you fly in any layer in the Stratosphere and above.

Like i said, feel free to add on i just think the sky needs more love too

Love the idea! 100% support from me!

Thanks for testing it! However, that is a known problem (the "spawning in the ground in the Overworld" thing).

Also, the portals are generated with the world, they cannot spawn in chunks that have already been generated. Sorry.

No problem! I'm glad I was able to try it out.
Also, if you need some help with mob ideas I could help you with those.

I don't think I need mob ideas just yet.

However, I would want help on fixing issue #5 here.

I've tried using the Nether spawning function, but that will only spawn you below layer 128. Does anyone know how to expand it to spawn you around layer 180-200? I've tried, but it just starts spawning you in "caverns" it cuts out of solid stone to spawn the player in.

Thanks, but I need help with calculating the spawn. That could help with storing the spawn, but what I need help with is how to calculate it correctly.
