[Mod][Merged] Valleys Mapgen [valleys_mapgen]

[Nathan.S]

Hate to be a dummy but how do I use this?
Does it need to be installed to some place other than mods? It doesn't show up as a mapgen I can use when creating a new world. Everything I've heard sounds amazing and I'd like to try it out but I can't figure out how to.

I believe you need to make a v7 mapgen map. Then it should work.

[Nathan.S]

Absolutely correct you are Don.

The screenshots don't even begin to do justice to this mod, I just followed a river upstream for quite some time, very impressive. This is going to be my new go to mapgen.

[Gael de Sailly]

The name of the topic was wrong. It's simply a mod.
The mapgen used in your world don't matter : it's overridden by the mod.

It sets mapgen to singlenode so doesnt matter which mapgen u choose.

[Nathan.S]

I guess last time when I tried my t I did something wrong then, not sure what though...

[Tom]

Very impressive mapgen! Keep up the good work!

[Gael de Sailly]

I'm back !!!
I've worked on the rivers shape today.

[Gael de Sailly]

Valleys Mapgen 2.1 released !

List of changes

[webdesigner97]

This is one of the most beautiful mapgens I've ever seen! I love it!

[Clouds]

Based on the screenies ( haven't testing out my self ) this mapgen I personally think is the equivalent to a real geological world. Beautiful doesn't even begin to describe this wonderful mapgen. Great work Gael. Can't wait to see what is next.

~~~~~ ANNOUNCEMENT ~~~~~

I need contributors, because after the end of the holidays (August 31st), I will be too busy with studies to continue my project alone. If you're interested in working on this mod, don't hesitate to say it on the topic or by private messages. I'll update the ToDo list and add more code comments.

Everyone is welcome :)

[Gael de Sailly]

I've added many comments in the code, but I'm not sure that they are understandable.

They are, which by itself makes your code better than most I've seen. I'm always impressed by anyone who can use more than one language.

I made some high-resolution textures for vmg, since I'm used to using hdx textures. They're not up to Vanessa's standards, but I like them.

[paramat]

Explored this today, good mapgen.

[duane]

I'm adding more plants to the landscape, as well as water and mushrooms in caves (optional), in a fork. You can use the giant mushrooms as both food and wood.

The download is: https://github.com/Gael-de-Sailly/valleys_mapgen/archive/cavestuff.zip

This is a screenshot of a really overgrown cave I located. Quite a few caves have enormous waterfalls in them.

+ Spoiler

Obviously the underworld isn't the major draw for vmg, but I hate boring caves.

[Gael de Sailly]

I'll take a look at this on Saturday or Sunday if I have the time.

[duane]

I have to post some more screenshots. Amazing maps.

[Minetestforfun]

This is amazing ! BUT not done... need some contributor(s) to continu/finish the mapgen ! :)

[Gael de Sailly]

duane : I've merged your changes in a branch, and added you as a collaborator.

I've been working on adding volcanoes.

I've added randomness to create variable height and radius of the the volcano. Testing tonight and spawned a very large "super" volcano. Think Mt. Vesuvius.



Standing on the top of the volcano, looking across the cone.


Looking down. Volcanoes are currently dormant. I haven't figured out how to add lava into the void yet.


At the base of the volcano cone.


TODO:

1. Add lava
2. Currently only spawns once per map. I need to add multiple volcanoes to mapgen, potentially clustered in a chain of islands or in a mountain range.
3. In mapgenv7, a volcano that spawns on water will create obsidian down to the seabed to form an island. In Valleys mapgen it floats on the water. I need to figure this out.
4. Add variable radius to cone.

Don't expect fast progress on this. I'm very much still learning to code. Offers of help are welcome :)

[duane]

I've been working on adding volcanoes.

Cool. Ideally you want this to be based on Noise 11 and 12, which determine the occurrence of underground lava. I'm not comfortable with the details of noise functions, but I'm guessing that increasing the scale of 12 (or just decreasing the lava_depth and increasing lava_max_height settings) would bring it closer to the surface. Then you use something like the current lava placement code to locate each volcano.

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

if v11 + v12 > 2 ^ (y / lava_depth) and y <= lava_max_height then

Normally, mapgen.lua doesn't even check for lava except in caves, so it won't break out anywhere else, regardless of the noise function. (And if a cave's under a volcano, you want lava there.) Leaving lava_max_height in will let people tune out vulcanism if they don't want any, though we might consider making any change to noise 12's scale based on a setting too (and/or any possibility of volcanoes, but that might be redundant).

I guess after that, we need to decide how closely to monitor the volcanoes. Do we want them to potentially devastate an area (which a player might spawn in) or not?

[Gael de Sailly]

I propose to add another noise with very large spread parameter (2048 ? 4096 ?). Volcanoes should spawn where :

• This new noise 19 is close to zero (volcanoes will spawn in lines)
• noise 2 is not close to zero (avoid volcanoes near the rivers)
• noises 11 and 12 are high

That's just an idea, I haven't tested it.

[duane]

I propose to add another noise with very large spread parameter (2048 ? 4096 ?).

That sounds ideal.

This, on the other hand, is just the opposite. I was playing around last night and put together a few changes that make random lava flows pop up occasionally, causing havoc and destruction. They can kind of form a vague cone shape eventually, if you squint your eyes and hold your head just right.

Here are a couple of screenshots.

If anyone wants to see more, you can check it on https://github.com/Gael-de-Sailly/valleys_mapgen/tree/fireland. It's not a serious addition, but I'm having fun with it. Nothing like a raging forest fire to light up your evening.

Duane: ermehgerd! Thats fantastic!

Duane: ermehgerd! Thats fantastic!

The fire! It kills my fps!

[paramat]

Kills mine too, i think the firelike drawtype is too complex having 6-10 textures per node, it used to be plantlike with just 2 textures, maybe an option is needed https://github.com/minetest/minetest_game/issues/655

Woah, that's looks nice!

What I still confused about: "How can you make so that the water inside river doesn't flood lower area?".
