[Mod] Mount Meru, 2 km tower/mountain [0.3.1] [meru]

[paramat]

Before using the mod you need to edit the generation area parameters in the init.lua to a completely ungenerated area of your map, otherwise the mountain will not spawn.
If starting a new world, very occasionally the mountain may spawn right on top of you, however since mods do not work within your spawn chunk the lower part of the mountain will be missing, try flying upwards to see if the higher chunks of the tower are above you, if they are you will just have to start a new world.
If you want to cheat set parameter COORD = true to print the co-ordinates of the mountain.

HELP! I cant run the init.lua file because it says the name does not follow the naming convention! What is the real name that I should name it? I remember changing it and I don't remember what I changed it to. Just what should I name the folder. I followed all other directions.

[paramat]

The folder is called "meru".

These are images found online of the Mount Meru of Buddhist, Hindu and Jain cosmology. These images were part of the inspiration for this mod. The 'trees' on the hills are actually giant trees size of moons or something ...

[ShadowNinja]

This mod is slow because it uses minetest.(env:){set,add}_node() and minetest.(env:)get_perlin().
You could make it a lot faster if you used the LuaManualMapVoxelManipulator, but that would require Minetest 0.4.7-dev+.
Another thing you can do that should speed it up, although not as significantly, is using PerlinNoiseMap, which generates noise for the whole area and returns it as a table instead of having to call a function to get each position.
Hmmmm/kwolekr's Lua mapgen is an example for how to do this, although it is slightly outdated...
And FYI LuaJIT is very fast, faster than C++ in some cases even.

[Krock]

As already said by ShadowNinja, it is slow and could be much faster, using VM.

Could you update this mod please?

[paramat]

Okay, i didn't think there would be demand for an update so i waited for a request.

[paramat]

0.3.0
Fast generating voxelmanip / perlinmap version.

[Krock]

.3.0
Fast generating voxelmanip / perlinmap version.

Amazing. Thank you!

Finding the mount meru is a bit difficult..

[paramat]

It's meant to be, but you can always reduce the spawn area or cheat by editing parameters, see first post.

Fast generating voxelmanip / perlinmap version.

yay! one of my favorites has been updated

[Gravelpunch]

Looks super cool.

I have a question about it though. Surely the mountain ranges multiple blocks to generate. I'm wondering how you managed to keep it as seamless as it is, even though it is contained by different blocks, and thus generated at different times.

[paramat]

Eaxct same way as seamless mapgen, everything is defined per-node by perlin noise, and noise is a value that is continuous and smoothly-varying through all space, therefore mapchunk boundaries don't matter (... much. but they often create glitches).
I happy this is of some use to players, i find it a bit boring now, being one of my early mods.

Manipulated my mapgen to test this idea.

Looks ugly and too simple, compeared to the original.

Yet still pretty awesome

[paramat]

^ Looks good to me, hope you develop this.

[Wuzzy]

Thank you, paramat, for the 0.3.0 update. This was really important, no long waiting times anymore. :)

Can I change the coords of the mount meru to let it generate on an existing world?

iirc it doesn't like touching generated map blocks. I never got it to punch through existing terrain. I did get a lot of flying giant cones above generated landscape though the last time I tried. You can change a lot of parameters including position in the init.lua

[paramat]

Hybrid Dog, no, the mod would have to be rewritten to do that. The spawn area parameters must be set to a completely ungenerated volume of the world, otherwise no tower.

[twoelk]

Just tried the new faster version on an existing map of my brother's kids. Generated nicely in an unexplored part but it seems to have biomes missing. Didn't the old versions have nice patches of woods and jungles here and there? Had hoped the installed "glowing biomes" would populate the central hollow.

[paramat]

Yes this version uses mod's own stone and desert stone to avoid cavegen griefing at chunk borders, the original used default nodes, which somehow trigger bits of biome to appear. If you prefer the original behaviour just edit the default nodes into the 'get content id' lines.

[Hybrid Dog]

Actually I thought about generating it in an existing world but outside the generated map, sorry, I didn't read the topic description.
On globis' server someone claimed the mount meru as mese mountain, so I wanted to find it and...

[paramat]

Ah i misunderstood, yes to add a tower to an existing world, change the spawn area to an ungenerated part of the world. Mese mountain hehe.

[Minetestforfun]

My game crash when i tried to save with WorldEdit a mountain of "meru mod"...
Please can somebody give me a schem for WorldEdit of a mountain of this mod ?

[paramat]

It's too big to save as a schematic.

[Hybrid Dog]

It's too big to save as a schematic.

but if you use the hard drive, too and not only the memory?

[HeroOfTheWinds]

Your best chance would be to split it up into multiple schematics, and piece them all back together. And no, you can't jump straight from the game to the hard drive. It always has to assemble all the data into the RAM, then convert it to the proper format for schematics... :/

minetest.compress() could be used

Yesterday I got a memory error because my simulated lavacooling mountains were so big.

[Minetestforfun]

so, a solution exist for save a schematic of a meru mountain ?
