I`ve made a dummy player, so it is created automatically when a real player has gone into a vehicle and his hands have become visible:


Unfortunately, it is impossible to force a real player to be invisible in third-person view if he is attached to entity. Hence the following screenshot is not very good-looking:

Well, then...guess we better start saving for a costy expedition that's soon to come!

A space sation where a shuttle may eventually be launched from is already under construction:

Err... will the shuttle's computer use the MineHAL 9000 A.I.?
You know... ;)

That's just an x-ray view of geomoria. It's been around for years, but thanks for the compliment. : )

I used the same layouts in an experimental mapgen, which is probably closer to up-to-date. I love how pretty all the rooms look, but they were never very much fun to play with -- just lots of big, empty space.

This is kind of pretty too, and more procedural. (And mobs don't get stuck in it as easily.)

wow the attention to detail on such a large scale is astounding!

That these are procedural generated is mesmerizing! I love proc gen dungeons such as these..

You can try to set the visual_scale of the player to 0. I've seen that trick in some invisibility mods.

Yes. Use player:set_properties{visual_size = vector.new(0, 0, 0)}, alternatively set textures = {"blank.png"}

[Andrey01]

Ok, thanks for solution! I`ll try out to set the visual scale to null.

I'm going to check both, it's been a while since I've tried them.

duane,

CivTest

This is a basic "game". It contains sfinv, lib_player (my current player character mod), lib_materials, lib_ecology, and lib_mg_continental.

This should provide a completely self contained working showcase of lib_materials / lib_ecology working on a custom lua mapgen using 3 layered recursive voronoi to generate terrain. Voronoi cell data is available from mapgen.

Temperatures are earthlike, with tropical at the equator, (y=0), and cold at the poles, (y = 30000/-30000)
Continents are centered on 1st layer cells, and shaped based on 2nd/3rd layer cells.
Maps can be scaled from 1 to 0.01. World size is capped at 60000, and it is this number that scales, so a world map can be generated in 600x600.
This "game" can provide a base for RTS, RPG, FPS, and 4T style games.

A coastal scene at scale 1


A town generating on scale 0.1 map. (Towns and or Geomoria dungeons not yet included in this "game.)


A scaled world map, earth like in appearance. I custom edited the voronoi points to produce continents approximate to the real world. An experiment worth further exploration....

This is a basic "game". It contains sfinv, lib_player (my current player character mod), lib_materials, lib_ecology, and lib_mg_continental.

I can get that to run, although it still gives me a raft of errors and deprecation warnings, and I seem to be missing the "gui" mod. My first observation is that it's taking 5-15 seconds (not milliseconds) to generate a chunk. That's insanely long, to me -- I fret about adding a few hundred milliseconds to generation time. It looks like your code is pretty well optimized, so I'm guessing the voronoi math is just more than my laptop can handle.

The only thing I might recommend is to reduce the number of function calls, since lua has no inline functions. Note that I hesitate to suggest that -- I think legibility is much more important than speed, most of the time.

Generally, I tell people, "Get the code working. Don't optimize." In this case, though, it's painful just to wait for a landscape to appear while you're working. And I'm having a hard time finding land on this particular map.

You could try to convert the system to C at some point. Paramat has told me that he gets an order of magnitude improvement in speed with C. I've never seen anything like that much improvement, but he's more knowledgeable than I am. However, even that would only give you 1.5 second generation, which is still really slow.

Take all this with a big grain of salt. I'm still fairly sure that something's not working on my system, because I don't see anything like the pretty landscapes you get. I'd post a screenshot, but the forum seems to be incapable of taking attachments at the moment.

[ShadMOrdre]

Oops....

I've added the gui mod, as well as, sethome, sneak_glitch, and spawnpoint, all from MTG.

The version of gui and sfinv come from a github repository from burli, IIRK, where he had refactored a big part of MTG.

The generation times that you listed are consistent with what I get here, when all the mods are included. When running this before the addition of the gui mod, on_gen averaged 17 seconds. After adding the gui mod, on_gen times fell down to around 7 seconds. Yes, I am aware that this is rather slow, but I do not think the slowness comes so much from the mapgen, as it does from lib_materials and lib_ecology, both of which still need some TLC.

As for writing this in C for an engine based mapgen, that has been the goal. I just don't know if my C skills actually exist. Har har...

One think to point out, is the config lua file. While the options aren't yet documented, some are easily modified. There is a default "points" file, that the mod can load from the mod folder. The option is voronoi_mod_defaults, currently set to false. Set this to true to load the included points file.

I've found that the first time a new set of voronoi points are generated, the mapgen always just runs slower. If I restart the server, on_gen times drop.

There is also an option to add noise to the map using my modifications to Termos' Islands mod logic. This enables nice looking cliffs. Set map_type to "all" to generate the Islands noise on top of Voronoi cells. Set to "noise" to use only Islands noise, and set to "flat" to generate flat terrain. The flat is supposed to still generate the voronoi cells painted into the grass, but I think I botched that part. It's less useful for players anyway, more a dev setting.

Map scale should be left at 0.1, for now. This generates the voronoi within -3000 0 -3000 to 3000 0 3000. This has the effect of making all terrain seem closer. When set to 1, the entire world size is used, and terrain features are spread out, and hard to see the variations. I point all this out because when generating the voronoi points, I simply generate random values, with no weight or other processing on the values. As such, some voronoi cells may include more child cells than others. Meaning that oceans get big and deep, and you may have to move a good distance before finding land. A quick way to find land is to use one of the tier 1 point sets. These points mark the center of continents. These points are either the highest or near the highest terrain elevations, ie. mountains. The included point set is the "earth like" map from previous post. Land, at 0.1 scale, is close enough to see when spawning at map origin (0,0).

I am using MT 5.2.0 stable, on an Intel J2900 quad core processor with 8gb ram, builtin graphics with unknown memory, (256MB I think), and a standard 7200rpm HD. Nothing special by any means.

To make it run as lag free and smooth as possible, I set view distance to 20m, and alternate between full view and 20m. I find terrain generates and draws faster, even in full view, with distance set so low. Higher view distances cause the engine, and the client, to process and load far greater amounts of data before attempting to draw any of it. At 20m view distance, It loads and draws larger tracts of land quicker that trying to draw the same area volume with higher view distances.

That should give you a rough baseline for some comparisons.

Here is also my debug.txt, from the test I ran to make sure this all worked correctly. It shows the mapgen timing data.
