FOSS gamedev and creative worlds

Done&pushed VoxelManip. Can't say they are faster because I have a constant 3-10 second lag on the server (not sure why though, minetest was always super-slow for me since 0.4 was introduced).

There are 2 types of voxelmanip, one is for mapgen and worlks on a whole 80^3 mapchunk.

I use this one. I'm only interested if I need to run update_map or just calc_lighting. What's the difference?

There isn't a default value for light level, it's best to leave that alone because light level for each node is calculated at the end in 'vm:calc_lighting()' or 'vm:update_map()'. Wiki says these 2 methods are to be used only when implementing a map generator. But I need to move a structure of node...

There also is set_node_at and get_node_at. Can I use these to move nodes, or it won't be faster than set_node? And does it "move" the metadata?

How do I set a "default" one as remove_node does?

1. Yes you can get and set a big chunk of param2 (rotation) data, i'm now doing this in flexrealm to rotate nodes properly https://github.com/paramat/flexrealm/blob/master/init.lua Note you can also do this with param1 (light) data also. 2. Voxelmanip is exactly that, a way to get, process and writ...

1. Can I rotate node with VoxelManip? I tried to use it to speedup moving many nodes at once, but it just forgets the facedir. 2. Why is it implemented as a completely different interface? Was it harder to implement just a way to get the node area and work inside it with the old set_node and get_nod...

Nope, it does not work. Lighting breaks, node facedirs break too.

Added voxel manip. Now I'll test it on a live server and then commit and push to the repo.

I could not understand the wiki page about voxel manipulation, and don't see any other tutorial. If anyone can work with it, pull requests are welcome. There is not so many code :)

Nodes are stored in MapBlocks. Each MapBlock is a row which contains a "blob" of binary data to store the nodes within it. Therefore, nodes are not stored in their own rows. I'm not sure how meta data is stored, however. Oh gosh. Then I think this structure should be first rewritten to no...

Version 1.0 seems to be stable but I've tested it only for several minutes. So feel free to write about any bugs.

This mod allows you to connect nodes into a structure that can fly as a whole. The code was originally taken from technic' frames but changed a lot. You connect a node by placing a motor, connecting any blocks to it (no frames!) and punching it with a configurator. If there are no too many blocks in...

I doupt there will be a huge speedup if you add this into the core because the data must be deleted somewhere in the database and added on another place. It does not need to be deleted. Just update its coordinates. I doubt minetest data structure is so horrible to store coordinates and data in the ...

Is there a way to do subj? Now to move a node we need to do 2 heavy actions: remove one node and create a new node, and serialize/deserialize their metadata. Also, with this we lose all callbacks made on a node (IMO, I can be wrong).

My only thought for now it making some entities in the air pointing to the nodes that auto-destroy after few seconds. But maybe there is a more efficient way?

I'm currently working on a mod with flying structures (based on technic's frames mod but without frames and limiting the structure to connect by frames only). Any nodes can be connected to each other by metadata, and I need to see by punching them with a tool what nodes are connected to which ones. ...

Mipmapping is not related to filtering at all. It is just a method to use different textures for different resolution and object sizes.

Texture filtering is texture smoothing. Look at other games. Try using mip-mapping and nothing else. I began this discussion exactly because I saw filtering in other games, particularly minecraft that has the same resolution textures. There is filtering there and no smoothing (at least it is not vi...

Calinou wrote:This is intended, it is supposed to be used with high-resolution textures (64² at least, 128² recommended).

What for? Just shoothing the texture is not related to filtering at all.

If I enable any type of filtering, textures are smoothed very much even if I stand in front of the block and it fits the whole game window.

I don't want to regen whole map, just a region. I would be best to select it with worldedit. Maybe someone can suggest a lua code to run mapgen on a region? I recall worldedit being able to run plain lua code. You might do a backup of your world, then open the database with sqlite3, calculate the i...

What's the point of maintaining compatibility with old clients in open source? Anyone can get a new version free of charge and without any difficulty.

Emm, so what? Many free fonts contain them too, what's the difficulty in picking any of them? Not the fonts are the problem. From what I heard, the chat and almost every part in the interface would break compability to older Minetest versions. Compatibility was broken several times already. For exa...

as of 0.4.7 TrueType font is allowed and used This topic is two years old. Why do people not look at the dates anymore? Because the problem is still not fixed.

Currently was trying to run the latest tagged freeminer client/server. This is what I've seen at the first minutes: * Old minetest's lighting problems which I've not been seen in mt for a year: some leaves are black. * Strange water: I've seen a place just in the center of the sea that is 1 water bl...

Can I rerun mapgen on a region somehow? I have a very old world and some parts of it were generated with old generators. I want to regenerate them with current generator. Is this possible with this mod or any other? l think l read somewhere that someone made a python mapfix script. I don't want to ...
