FOSS gamedev and creative worlds

The extreme of game/engine split, break minetest down to a core functionality of maintaining voxel areas and providing an interface for manipulating them, real-time mesh generation. Offload everything else to whatever other program (ie. game engine) wants to utilize it. Most games/mods, as they exis...

Definitely a good idea, but should be done to give perspective of how diverse games can be. minimal developer test, minetest_game (or something, the minecraft equivalent), and then something else doing entirely different things with the engine.

video, core, io, scene are all sub namespaces in the irr namespace, supplied by the Irrlicht engine. ok, thanks. I'm looking through drawscene.cpp, you wouldn't happen to know where driver->setTransform(video::ETS_WORLD, core::IdentityMatrix); these variables (video::ETS_WORLD and core::IdentityMat...

Where are namespaces defined? For example video:: ? Are they all over or is there generally one large collection? or are these subspaces of core::, or something? I've looked in all the places I could think they might be (primarily headers included in files where they're used), but haven't found any ...

The inability to easily pillar up is definitely noticed and felt, coming from minecraft. I think I'd personally prefer that it just be 'fixed' (made more minecraft-like, but I can't think of any major problems with having an auto-pillar option as well (when placing blocks below you automatically mov...

I presume we could gain about 6 % in all directions by increasing map generation limit. This way, we'd have worlds of up to about 32768 blocks in all directions. Not that much, but it's worth trying. the current code has an arbitrary limit of 31000 (defined in constants.h, very easy to change), as ...

By which I mean, connection to minecraft servers, loading of minecraft maps. To get this a lot of new features would be needed, mostly what is being discussed in https://forum.minetest.net/viewtopic.php?f=5&t=9183, far larger world size and variable height limit (minecrafts real blocks are 60m x...

-> you still can't go further than 214748 because of the way floats are sent (a 32 bit integer)

Could you elaborate on this? And the nature, root cause, of the current codes 2^15 limit?

Is there any reason for blocks to be 16^3 nodes, as opposed to any arbitrary size? // Dimension of a MapBlock #define MAP_BLOCKSIZE 16 // This makes mesh updates too slow, as many meshes are updated during // the main loop (related to TempMods and day/night) //#define MAP_BLOCKSIZE 32 I've toyed wit...

better in-game statistics and info panels (even a full statistical menu, all variable, modifiable in real time, look-based node/block picking and readout/modification), block border highlights of some kind (including occluded but loaded blocks)

real dream would be actual documentation

how about an option for world gen, that places a predesigned tutorial structure at spawn, a small 'hazard course' with popups to explain controls and some basic crafting, plus stuff like how fluids work, fall damage, etc. plus the structure itself would be a good source of resources. basically an ex...

Predictive block loading/generation for caves. So you want the mapgen running on the client? That won't work for Lua mapgens anyway, or for servers with mods that affect generation. I didn't bother to expand much on that one because I figured there would be an immediate reply "it already does&...

Tessellation, combining of multiple node faces to reduce the total number of polygons to be rendered. What kind of tessellation does minetest feature? Minecraft had a lot of work put into its tessellator, in the earlier days of its development, but it seems to have been abandoned at some point. Does...

can nodes have multiple sound types, for example with ladders both one for on first attaching to it, and for actually climbing it? or how about randomly selecting from multiple different sounds?

This goes against the principle of the server having the map with everything that belong to it. I have to agree, that this should always remain the case. Client side activity should be limited as much as possible to graphics. Allowing mods for this would be a good idea, and as I see it would probab...

This would be a good thing to ask one of the active engine developers about. It seems like something that might be a matter of literally just enabling. I couldn't see much use for it, though. Maybe it could be combined with the tessellation (does minetest even use any tessellation?) somehow, for an ...

A big problem in minetest would be, where's the 'top'? It's a fully 3D environment, and gameplay is highly vertical. A map showing just a top-down view of the surface (from worldheight cast down to the first solid block), would be very possible, and in fact exists (a few different mods for minecraft...

Blending sounds like a good idea, i have a feeling it's possible in a clean mathy way, or at least wrapping in one direction only, like a tube world. Great! And something to remember, except for the corners it's all going to be in just one direction, either left/right(x) or top/bottom(y) edges bein...

What would happen if people ... mine ? That's actually the exact problem I have with the true 3D cube world concept. If players are constantly changing the shape of the planet it would seem to me you'd quickly wind up with significant 'gravitational anomalies'. What happens when a player digs to th...

Depending on which of six regions you are in (determined by which primary axis coordinate has the greatest magnitude and its sign), up/down would just be in a different direction (for determining camera orientation, gravity, and "height"). There'd be the +X region, and -X, +Y, -Y, +Z, and...

The engine likely doesn't think in terms of animation frames: currently, you can use any amount of frames for the breaking animation, it's fully client-side. This makes me realize, I have no idea how node breaking even actually works, in minetest. I know it's probably not anything as straightforwar...

> Perhaps easier to do what kilarin suggested in the other thread, where i guess you would add an XZ offset to each layer in the stack. emugod, ah that sentence has a double meaning, what i mean by that is: kilarin's idea seems easier for me to acheive in a lua mapgen, because it doesn't need 'circ...

I think the 'wraparound logic' that's being discussed would be a very valuable addition/change in its own right, with more good uses beyond fudging world space/size. Like creating 'spherical' worlds by removing any edge, having all four edges of the map loop back to the opposite edge. Or you could f...

Now can you make it wither and die, collapse, spreading slowly outward from the center?

Hm i can now see problems with this, because essentially you need the 2 opposite edges to have identical terrain, and perlin noise doesn't do that. Perhaps easier to do what kilarin suggested in the other thread, where i guess you would add an XZ offset to each layer in the stack. you mean this pos...

Thanks for the answers paramat. What do you think of procedurally bridging two far distant (technically, although for play purposes in this concept actually quite close, after whatever teleportation or 'treadmilling' effect is done) and very differently composed (presumably/possibly) blocks, to prod...

This sounds like a really great idea to me. Adding more data for each node to carry should always be carefully considered, but this seems like a small additional burden, that could open up a huge number of new possibilities. Already I'm imagining explosions leaving behind highly damaged blocks aroun...

There have been threads on this. I browsed through the entire engine development subforum and didn't see any, and searched the whole of the forums for relevant terms (like but not limited to the three in the thread subject). In any case, is that all you have to say on it? I'm not surprised it's bee...

paramat already worked on a sphere mod: https://forum.minetest.net/viewtopic.php?f=11&t=7887 I've actually already spent some time browsing through all paramats posted topics, before making this one, and was hoping he might chime in here (might even send him a PM requesting his input, in a day ...

Like a spherical world, where if you keep walking in a straight line you will eventually return to the starting point (and thus also the world is necessarily of a hard limited size). But of course not truly spherical, rather just a normal square map of limited size, that tiles with itself. Would on-...
