Oohhh, that's clever. Thanks for the idea.

We support devices older than 5 years old. The argument was that gameplay and advantage giving features shouldn't rely on shaders. Implementing self-illuminating textures shouldn't require anything more complex than what Minetest already does with lighting. It already sets custom texture brightness...

If you make the led's a separate node and place it after the machine is placed then it could be lite. The problem is that if the light level of a node is low, then even a white (255,255,255) texture gets rendered as dark grey. If the light level is high, then it throws light everywhere as if it wer...

ArguablySane have you looked at walking light? It does what you want. https://forum.minetest.net/viewtopic.php?pid=36928 Thanks. That would work as a temporary solution. It's not exactly what I wanted though. I'd prefer it if there was a way to make an object self-illuminating without having it cas...

It would be really nice if there was a way to specify that an item is self-illuminating when held in your hand (ie. it gets rendered as if you were standing in full sunlight). I've been playing around with adding a type of glowing gemstones to the game, but it just looks ridiculous when you're holdi...

+1 @Arguably Sane. That has always been my favorite method. I just hope i doesn't look as bad as the bones from the bones mod. We should have a Dead Sam model instead of a node. Just make him laying down, perfectly still, and with a bones skin. Or maybe like a skin overlay... I hadn't even thought ...

Is that really the purpose of mods to create huge complete buildings? Not all mods, obviously, but there's definitely a largely unexplored niche for mods which generate buildings and roads rather than hills and oceans. Imagine a zombie-survival type subgame which starts you in the middle of an aban...

Steam is proprietary crap with built-in DRM and spyware. Valve promote exactly the opposite values to those of the open source movement and Free Software Foundation and make the world a worse place by existing. If anyone had any lingering doubts, the fiasco with trying to commercialise Skyrim mods (...

Not every monster should drop meat. A monster should drop food, but not always meat. And sometimes it doesn't drop anything. I'd actually like to see a corpse/butchery system instead of the Minecraft approach of just having the mob leave loot on the ground. When a mob dies it should fall over and r...

Don, am I right in thinking that you want to assign the value of chis1/hori1/etc (in this case "stuff"), to node_box? You're going to have to iterate over a table of references to each type, but it would be helpful to know exactly what you're going to be using this code for. If I know the ...

I just tested this on Minetest 0.4.13-dev using the following code:

It seems to work exactly as expected.

By default, it's air (minetest.get_content_id("air")). I believe there's a way to customise it from within a mapgen mod though.

http://i.imgur.com/Qotg9fH.png Just a quick preview of an improved cave generator. It doesn't use Perlin noise, Perlin worms, or anything else named after Perlin. Eventually the caves are going to look less like balls and sticks and more like actual caves. EDIT: If you're wondering why it's an impr...

When you're building something, you'll frequently place a node somewhere where you'll later on decide was the wrong place. That's why I suggested adding nodes which can be dismantled easily from one side using the right tool, but are very difficult to break from the other side. You'd just have to b...

[*] Doing away with biomes in favor of something more generic. The biome concept places artificial restrictions on what can happen at one location in the world, by assuming a fixed, unchangeable set of environmental parameters. This is what bugs me to since the beginnings of the biome system. It on...

Hi there, the minetest.find_path() function has an parameter to set the searching algorithm ( "A*_noprefetch", "A*", "Dijkstra" ), I am wondeing what the differences are. Is there a documentation on them somewhere? Wikipedia has articles on both Dijkstra's Algorithm an...

Yes, but to make caving an exciting element in Minetest something has to lurk in the dark. Part of the excitement of going underground to gather resources is in the inherent danger it presents. I agree that zombies are overdone but maybe ghosts or just more environmental hazards? I agree, but I thi...

I always get a load of "ignore"s returned to me. I think I must be missing a step or not doing something right. You're probably missing the minetest.forceload_block(pos) part. If you try to get map data from a section of the map which isn't loaded then you'll just get a load of "igno...

That's perfect, thanks. I'll remember to use that site (or lua_api.txt) in future instead of relying on the wiki.

rubenwardy wrote:Isn't Minetest. Serialise position for this purpose?

Is it? Can PseudoRandom(seed) accept a string as its seed, and will it use the entire string rather than just truncating it? If so, that would simplify things massively.

Here's a function for spawning the player in a random position: https://github.com/CasimirKaPazi/spawnarea/blob/master/init.lua What you're trying to do is very similar, so take a look at that code. Basically, calculate random x, y, and z coordinates within some volume, use minetest.forceload_block(...

When do you need to place the node? While generating the map, or later?

Do you only want to place a single node once, or do you want many of these nodes randomly distributed throughout the world?

Does anyone know of a fast way to hash 2 or more numbers together in Lua such that the result is deterministic, depends on the order of the parameters, and has a reasonably low probability of collisions? Almost any standard hash function would be fine, but Lua 5.1 doesn't even support bitwise operat...

Why? Lua mapgens aren't that slow. How complex is the dungeon generation code?

I'm going to reply here because I don't have a github account yet. I like ruben's idea of movement patterns for swimmers, walkers, flyers, etc. Those should be implemented with fast c++ functions which take the mob towards its current target location. Those functions should also run on both the serv...

You've done good work, Jordach. Minetest certainly needs more polished features like player animation. I would say that I think the "resting" animations should be slowed down by at least a factor of two and the amount of movement should be reduced even further. Also, nobody swings their he...

I think the griefing problem (both intentional and unintentional) is caused by the simple fact that it's easier to destroy something than to create it. Almost any conceivable structure in "vanilla" minetest can be destroyed with a pick and a bucket of lava, and it takes a fraction of the t...

Personally I think it's a silly question. We shouldn't care how similar or different Minetest ends up being to Minecraft. There are some things Minecraft did well and some things it did badly. There are some excellent Minecraft mods and some awful ones. We should feel free to borrow features which w...

NumberOfClusters := Round( (ChunkVolume/ClustScarcity) + (Random(-100,100)/100) ); That might work, but it wouldn't be ideal. As scarcity increases the number of clusters should tend towards zero, but using your code it would tend towards a random number between -1 and 1. Negative numbers of cluste...

Regarding ABMs, is there any way to detect if a node is near the edge of the active region of the map? I'm trying to create more dynamic trees, but when the trunk lies just outside the active region the active leaves stop receiving their keep-alive messages and die. I could put the code to check if ...
