2.3 progress

As you all know, 2.2 doubled the height of the world. This was a long overdue change that allows you to build properly high structures. It also doubled the size of the world files. It’s this doubling effect that I want to focus on this post.

Back in 2016 when releasing 1.29, I doubled the size of each block to use 32 bits. This doubled the size of the world files too. In 2.2, the increase in height doubled it again. The files have become huge – some larger worlds are reaching multiple gigabytes. This is something I haven’t paid enough attention to.

Another aggravating change I eventually relented on for 2.2 – after getting much feedback from you – was to increase of the maximum worlds limit on device from 20 to 30. In hindsight, this may have been a mistake.

The problem is that many, many people are running out of space on their devices. They download many large worlds from Community Content and everything grinds to a painful halt.

Another issue caused by large worlds is exceeding of Dropbox bandwidth limit for people who host their worlds for Community Content. This has always happened, but now, with worlds twice as large, it happens twice as often. The result is worlds becoming unavailable and dropping down through the ranks, until Dropbox unblocks the account after a few days. At that point, the world is so far down it might never climb out again, no matter how good it is.

As a result, one of my priority tasks for 2.3 is to change the world storage format to reduce world sizes.

2.2 and earlier use a naive format, where chunk data is stored verbatim – every block taking 32 bits. This is very inefficient, but very fast, simple and error-resilient. It also means that every chunk has exactly the same size on disk, which is extremely important. Here’s the description of the current file format: https://kaalus.wordpress.com/chunks-dat-file-format/

There are multiple compression schemes we can use to reduce the size of the chunks. Even something as simple as RLE (run length encoding) is likely to cut the size by a factor of 5 or even 10. But compression is the simple part – it’s not the issue here. The problem is, once we compress chunks, their size will no longer be the same. This opens up a Pandora’s box of pain. Fragmentation. Splitting chunks into little bits to fit in between other chunks, which have became smaller in the meantime. Etc.

Basically, what we need is a proper filesystem, with chunks being files with random size, that can both grow and shrink. And it has to be RELIABLE. Application on a phone leads a perilious life. It can, and frequently does die with no warning, at any second, due to user pressing the home button, or system running low on memory, or the battery going flat. What if it dies while chunks are being written to disk? At the moment, at most one chunk might get corrupted, and even this is unlikely, as chunk write is nearly always an atomic operation. Either it all goes in, or nothing does.

With the new complex format, we will suddenly be opening ourselves to complete mangling of the chunks file in case something goes wrong. As a result, the world will become lost forever. This cannot be.

This is what I am wrangling with at the moment. It’s proving to be more complex that I though it will be. We actually need a journaling filesystem, as ext4 or NTFS are.

One might question, why don’t we just use the Android’s or iOS’s filesystem, and save chunks in separate files? The answer is performance. File open operations are very slow, especially so on mobile systems. Even desktop Minecraft doesn’t do it this way. It combines multiple chunks into one “region” file. Plus, I’d rather not make myself a hostage to particular implementations of filesystems on various phones, which may become faster or slower over time, with no control from our side. I’ve been there before, and no, thank you, never again.

    I think you should just implement 3D chunks. This means that every chunk is 16x16x16 and also has its own Y coordinate instead of just X and Z. This would both make the world height virtually infinite and make the world size smaller for worlds that do not take up that much height. The Y coordinate should be just a byte long, making the max height 4096, which is usually more than enough.

      I literally was typing that exact same comment when i realized it is already there. I think it would shrink the files down quite a bit. When a player is only building on the surface only the top chunks need to be saved. The whole underground would not have to be saved as long as the player didn’t build/destroy there. Also i think it could help with the complexity limit (although i think that’s already fixed anyways).

      I really hope we’ll see 3D chunks in the game. It would be awesome.

        People would be amazed how this would just catapult SC into popularity. This would have been true even before the furniture and pistons updates, which could be counted as the largest updates on SC before 2.2. I have played stupid clones like Zycraft with my boys just to be able to play with them. Why? Because it had MP!

          I personally know a handful of people who quit BECAUSE it doesn’t have multiplayer. And the splitscreen is useless to them. They just laugh when I mention it. (and not a good laugh) When we get LAN/WAN play, they’ll come back to it. Until then they play MC…

          They do NOT need a MMO server or ANY world server. All we need is a P2P system where we can join a friend’s world. I’d bet 90%+ of us would be satisfied with a 4 player limit too, so it doesn’t have to accommodate dozens of players at once. We don’t even need a link server – we can use other means to share our links. Perhaps even CC can be expanded to include real-time play links? But even that isn’t necessary. People can find ways to share them, such as a chat service like discord which could also be used during play!

    Read through the chunk.dat specification. I think I understand most of it, but I don’t understand the point of the chunk header, especially when the directory entry already has the chunk position. Maybe I’m missing something.
    Either way, it’s not like that’s taking up a ton of space.

      Speed. Without the directory, you’d have to search through the entire (potentially multi-GB) file every time you want to see if a chunk is included AND to find it each and every time it need modifying.

          Posted January 19, 2020 at 15:35 | Permalink

          The coordinates ARE the search parameters. That’s how the game can tell if it already saved a chunk or not – and where to find it, if it was saved.

    I have an idea, it may not be optimal, but it’s something.
    What if you decompressed the data primarily when the world is loading and when the player closes it, and then just saved it at some regular interval (like maybe every 2.5-5 minutes) instead of when a block is placed/removed.
    If the compression saves enough space (if I understood right worlds could potentially be 5-10x smaller) you wouldn’t have to write directly over the old data, you could delete the old data only after the new data has been written successfully.
    That way, if something were to go wrong (app closed, etc.) the player may lose 2-5 minutes of progress, but not the whole world.

    I’m not sure if this makes 100% sense.

      So we’d have a chunks backup file like we have a project backup? It would have to be permanent file for the occasions when writing to the main file IS interrupted – say by a power loss. Thus (re)doubling the world size again.

      RLE seems a good choice to compress natural worlds but in highly constructed worlds, the compression ratio could be significantly less than optimal.

      • Posted January 18, 2020 at 15:44 | Permalink | Reply

        So I don’t really know anything about RLE or compression in general, so I’m not sure if any of this would work.
        But, if the worlds were 1/5 of their current size, doubling that would only make it 2/5 of the current size, which would still be massively better.
        What I was trying to suggest anyway, was to have one game file, but when a game is saved, write it to a new file first. Then once the new file is confirmed to have written successfully, delete the old file and make the new file the main one.
        That way the world is only double in size temporarily.
        I don’t see why that shouldn’t be possible, but like I said, I know little about compression and this may not work the way I imagine it would. And it may just playing not be feasible when you’re dealing with GB’s of data.

        I do get what you’re saying. But you have to play the “what if” game since the device can crapout at any time. What if it exits just as the new file is written but the old one wasn’t deleted? There would be 2 files so how does the system know which to pick from when it starts back up? This contingency has to be accounted for – as well as many potentially more devastating scenarios. Thus the game has to assume there could be the ‘main’ AND ‘backup’ files.

        RLE is very basic and easy to understand. If you have eg, 6 granite blocks to enter next, instead of writing down granite six times you just write (6)granite. That’s why it’s less effective in built worlds – there’s fewer areas of solid, identical blocks. When there’s almost no repetition it actually increases the file size. Instead of entering WATER GRANITE DIRT GRANITE GRAVEL, you have to enter 1 WATER 1 GRANITE 1 DIRT 1 GRANITE 1 GRAVEL. However this is extremely unlikely and RLE will almost always give a reduction in file size but the reduction is very dependent upon the data itself.


        • Posted January 18, 2020 at 20:55 | Permalink

          Ah, thanks for the explanation of RLE, that makes sense now.

          Looking at your first reply again I think I misread it. You were saying that there would have to be a permanent backup, while I took it that you thought that’s what I suggested. Sorry about that.
          And yeah, there’d have to be a ton of contingency plans. Long story short, I’m not sure if it’d be viable at all, I was just throwing it out there.

    Hello Kaalus, try JFS file system, it’s robust, performant, tested (made by IBM) and free to use. It’s used in Linux systems and proven to be very stable.

    Ouch! The in-game memory usage can be dealt with but yea, pushing the dropbox speed limit is pretty bad. Especially with the result of confusion in the CC. Just an out-of-the-box idea tho – perhaps a revamping of the CC routines could be helpful…

    This problem surely is quite a sticky wicket! Well – another popular block game is Block Story and it has ‘infinite’ height so probably uses full 3D chunks. But taking a look at how they do it might give you some ideas.

    Kallus, I am often using Sqlite3 as a fast and reliable replacement for system filesystem. You can create a single table, put indices over chunk coordinates and inside a blob column store your compressed chunk. In my case, this operation is often really fast. Please think about it it may help a lot with fragmentation!

    There’s yet a bug in in Survivalcrafts electronics:
    When certain electrical components are directly connected trough the edges of two diagonally adjacent blocks, and when there’s a wire on the same block on which the component has been placed, the component will lose it’s logic.

    This image has two examples of the bug:

      Actually I find timing strangeness happening just when having electrics connected without a placed wire between them and started avoiding it altogether. Yes, it means bigger builds but it’s traded for reliability and I’ll accept that tradeoff when I have to.

    Kaalus, there is another reason why the downloads exceed the limit. When you download a big world, SC gives a timeout error and the download fails. Then you try and try again, just taxing dropbox more. I think this is a big problem. Also to upload big worlds just does not work at all. It always gives an error that you have cancelled.

    I have to do this manually. This is more difficult in windows. I have to take another world file and manually copy files into scworld file as well as extra content files and only then upload to Dropbox manually.

    So it is not only downloading, but uploading as well.

    Remove Level system it is arbitrarily restrictive and violates your creed of realism. Instead why not let in-game time meter to increases due to experience.

    SC2 is just not as fun as SC1 IMO due to food rot and levels. I could live with Rot if level restrictions were removed.

    At the minimum allow these features to be turned off.

      Posted January 18, 2020 at 18:16 | Permalink | Reply

      I disagree. We do not gain experience just by existing. Experience is only gained by practice – by DOING things. I think if anything, it should be expanded or detailed. E.g., we become better miners ONLY by mining. We become better hunters ONLY by hunting. Etc. How is it that by mining ores we can magically run faster?
      My biggest beef is having to chase around little golden balls in order to receive the experience we already EARNED by DOING.

      BUT – the game cannot become too involved or detailed without getting bloated and turning into another Skyrim with its reams of bugs and intolerable lags. So I understand the simplification and just wish there were better rewards for the higher echelons of levels. Once I manage level 4 or 5 it’s quick to ascend to 9 or 10. Then it’s easy to get to 20. Then beyond that – what’s the point? TBH, usually once I’m at 8 or so, I’ll start actively AVOIDING those bouncing golden balls. It gets less fun when I know I can simply outrun everything or just beat it into submission with two smacks of a stick.

      • Posted January 23, 2020 at 17:18 | Permalink | Reply

        Yes I agree just existing does nothing. My main gripe is that one can collect the resources to construct something – only to be told you must wait because you are not level X. IMHO the experience you gain from collecting the resources required for a recipe should be sufficient to use that recipe. The ingredients demand you put in the work. Let “levels” dictate other things like speed and strength. If you kill with 2 blows of a stick because you attained a high level, you deserve to. That’s a great reward. I don’t want to see that removed. I even see death resetting levels as acceptable. And rot, okaay. But the restriction of recipes due to Level X is a downer.

        In the end Kaalus has to balance challenge vs fun. he’s soliciting feedback on fun. I think this is negatively impacts fun, at least for new recruits. And it is a game, not boot camp. Toggles would provide both newbies and advanced players what they desire.

        BTW thanks for the great details on the higher levels. This provides some hope. I’d love to get to your point where I’m leveled too high! Alas will take awhile, got to spread out the game hours if I don’t want to end up divorced. 😂

          Posted January 30, 2020 at 16:28 | Permalink

          I wouldn’t mind a more complex levelling system, actually. I disagree that all recipes should automatically be known and doable. But there’s other ways to achieve it too. E.g., Block Story requires certain (training) quests to be completed before advanced recipes are known. Perhaps we could have a crafting experience tree in addition to the general xp gathering.

          Say, you ‘learn’ higher recipes after making so many of the ‘lower’ ones. The new recipes could have a high failure rate for the first 5 or 6 attempts. This gives us the experience to craft them better and then they’d always be successful.

          …and the “two smacks with a stick” was clearly an exaggeration…

      I disagree with you. The leveling system is an incredible system that makes a huge positive difference in the game as Stanimus said. But it is true that after a certain level, it becomes a bit too easy. Maybe it should unlock a new preditor or something like that.

      I like the levels system and food rot, BUT! I do totally agree that there needs to be way more settings for both creative and survival. One thing I really really dislike is that you can change settings for precipitation/lightning in creative but not in survival. I think it would satisfy both parties (People who want harder/easier) if in settings you could adjust starting stamina, speed resilience, etc… separately. Also if you could optionally disable being affected by temperature (for people used to mc) and separate lightning and precipitation. I like snow and rain, just not the stupid lightning that comes with it.
      Now that I think of it, what would be truly awesome would be if you could customize the game modes. I don’t know how hard it would be but if you could edit challenging or harmless or even make a whole new mode where you could set the starvation, fall damage, food rot, whether you get attacked by animals, HOW OFTEN DIFFERENT ANIMALS SPAWN, or even ore frequency. I think that would be up with the furniture update for coolness.

        Now those a great ideas, they’d really expand what you can do with Adventures.

        I’d love a release with just toggles added for all these high impact features. It could help retain new players; as they gain confidence they’ll flip more features on. Or off as Stanimus might, avoiding yellow experience orbs at broken levels as he does now.

    Indeed, if a world pre-1.29 was 25 MB for example nowdays would be roughly 80 MB with 2.2 due to 32 bit conversion and new height limit.

    Good to know that you’re planning to find a way to optimise memory size!

  20. Posted January 18, 2020 at 18:19 | Permalink | Reply

    I’d like the bring up the idea of cubic chunks again now that you’re taking another look at it. Which basically saves the game in smaller chunks. But generates way more on both xz axis and y. (Scalable height limit)

    I’m not familiar with compression. But to me these smaller chunks might actually lower the file size over time. Currently the world saves are pretty much identical to where you’ve been and modified terrain. Chop down a tree? New saved chunk. Mined for awhile in a 2 by 1 tunnel? More saved chunks. Just. Needed to dig yourself an emergency hole for a night? Even more saved chunks. This isn’t a big deal. Except the chunks are now kind of massive.

    I’m most interested in the fact that you could do crazy things with unlimited hieght. True mountainous terrain as well as deep mines that have natural heat barriers stopping you from going any further.

    I think block story already does something similar. Or atleast has near infinite hieght. Then there is a Minecraft mod you can looks at and even (quite easily) ask the devs from advice from.

    Wait –
    we really have two issues here: Loaded worlds take up a lot of memory and saved worlds take up a lot of memory. They do not have to be the same problem or need the same solution.

    The bloat from loaded worlds is really a direct consequence of user actions. Unless it leaves the system without sufficient resources it ‘s not even a problem. This can be remedied simply by user awareness and self control. It really is not your responsibility Kaalus. However if you wish to be helpful perhaps a quick system check when the game starts up and if it’s using up more memory than [some limit] or there’s less than [some other limit] of system memory left, the user gets a warning message with brief instructions about backing up and deleting unused worlds. Maybe even reinstate the lower world count limit. I for one, have never run into this limit. I prefer to keep my worlds outside the game if I’m not actively engaged in them.

    This means the internal representation can stay the same and only the uploaded format needs to be compressed. Very big worlds already take awhile to compress for uploading so a bit longer to compress the chunks file would be no surprise. The game need not be slowed down by an encoded file while uploaded files could be more tightly compressed. Of course this does mean that out-of-game visualizers or editors would have to compress/decompress the file.

          Players should be able to build whatever they want, not be restricted by some kind if technical limitation. Players shouldn’t be forced to use “self control” in a sandbox building game. And maybe you can easily backup and move worlds around, but the average 5-year-old playing this game might not want to go through the hassle.

          This is such an idiotic argument.

          Why can’t I just do anything I want to without limitations or consequences?
          Why can’t I have infinite memory?
          Why isn’t everything I want free?
          Why should I actually LEARN something?
          Why isn’t the whole world all about ME ME ME ME ME!!!?

          This is called REALITY, buddy!

          The “technical limitations” EXIST. Everyone must learn to live within them. (Who in their right mind would let a 5 y/o play this game with NO supervision, anyway?)

          So what, when you hit a wall, when there’s a small challenge, you should just give up? “Eh, it’s too hard, just let someone else deal with it.” If that was the mindset of the human race, we’d still be stuck in the dark ages. Why should we have to learn to live with something when we can instead learn how to overcome it? I imagine this whole game was impossible to make 50 years ago. I bet there were more than a few “technical limitations” back then, such as “Oh no, my CPU only has a clock speed of 375 kHz”. Where are those technical limitations now? Gone. Engineers and programmers and designers have been hitting technical limitations since the beginning of computers, and getting past them. That’s how technology advances.

          So now, Kaalus finds a problem, makes a post about it, and your suggestion is “Just give up.”

          And yeah, many parents just give their kid their phone and say “Go sit in the corner and play a game or something.”

    Please don’t change the world limit back to 20!! Even 30 isn’t enough! I have 128 gb internal and 128gb sd card, big world’s are nothing.
    I understand that not everyone has decent space but it should be up to the user to decide if we want 1 world or 100! We should be able to manage our own space how we like.
    Maybe put in a setting thats like safe mode where for the average user it sets a world limit for them but can be disabled for unlimited worlds.
    It’s horrible when you have lots of awesome ideas in world’s and then want to check out some community worlds but can’t because you’ve reached the limit.

    Kaalus if flu, rot, hunger, temperature etc… are a problem then I think doubling the time for the day cycle along with the other mechanics could solve the issue. Also it’s really strange that desert biomes don’t cause the player to become hot during day times. I think it would be a great idea if this is tweaked and made so that staying for prolonged period of time in the day time in hot biomes can lead to heat strokes and what not. Since I am suggesting you to increase the duration for things like temperature or hunger bar, making it so that it effects the player’s overall stats would make a great penalty as it’s a similar effect to the human being in the real world and would be an interesting concept. So if hunger and temperature penalties could be a bigger concern if implemented, I think having a wider range of food sources especially small would have a good impact on survival since players would require to go in small steps during their survival. In case you have not heard of this before, I think the way the player is reliant on finding wood or ground stone is not useful. That said, having the ability to craft without a crafting table especially for the simple beginning tools would be way more helpful since you basically can’t do anything if you can’t find a tree. Speaking of wood and stone, cooking on a campfire would be a great feature so we aren’t forced to dig stone from underground just to be able to cook food. I am willing to help improve the game’s overall gameplay and I am suggesting things like these. Please let us know about your current status and whether or not you are taking our feedback and suggestions. Also thank you if you read this far.

    Sorry for bothering you guys again with this. Do these roof tiles appeal to you?

    I see the the furniture dropped down the list, but I think it has to do with how the rating system works as well as Dropbox giving errors with downloads. The more colours texture pack also dropped down. Do any of you use this in builds. It actually is great even in survival. The big doors are nice to use.

    The texture pack gives new colours when you paint marble, sandstone and basalt, using clay plain texture though. It gives you great new options like orange etc. which is needed with the roof tiles. Remember that you can paint those tiles as well.

    You will need this:

    Furniture pack: Roof Tiles ETC. (need to scroll down even if it has a 5 star rating).
    Texture pack: Johan More Colours Marble (also scroll down on CC)

    Please give your opinion here if I must change anything.

      I have chosen a few textures that are more medieval for this texture pack. This pack however also includes the more colour options when you paint basalt, sandstone and marble. Let me know if you do not like this.

        Maybe base the texture for chest off of pirate treasure chests. They are usually dark hardwood with brass or black iron hinges and handles in the sides. You could add some hint of jewels, pearls, coins or gems near or on top of the lid.

        I noticed in your latest texture pack several paintings are present but I’m unclear on what I would need to craft to get those in a game. (Do you have a list for players who want to add some paintings while using your textures?)

        It’s too bad the recipedia doesn’t use your textures too (while a game is underway…)

          The paintings are the logic gates that is part of electronics. So you have to craft one of them. I have not included the paintings in the Survival pack, but could if somebody wanted them.

          You are always welcome to request things from me. Even if you want a photo of yourself as I texture, I can do that. The logic gates are a good option for that. It makes it a bit more difficult to use, but for myself I have added little dots so that I would know how to use them. You can see it especially in my world “Johan Real Colour TV”

          I have changed the chest a bit as well as the oven, but might change them again. (survival pack). Have you seen the skins I have made? I like realistic skins. You can look at Real Blonde lad and real blonde gal. It seems others do not like them, since they are way down the list, but I think they are good.

      I think those roof tiles are cool. I wanted to something likemthat but the complexity limit was a stopper.

      I would recommend making another small piece that fits underneath them to fill in the little ‘dips’ in the bottom of the roofline. At least for the overhangs. To help make the look smoother.

        Posted January 22, 2020 at 20:08 | Permalink | Reply

        I thought of that, but am worried that the complexity might become an issue again. I also do not want to take up too many furniture slots. Remember that everytime you paint something, it takes up double slots. Generally you also do not look at roof tiles so closely. I actually made these when the bugs were present and just did not use it because of the bug. I also had them with higer resolution (smoother), but it increases the complexity.

        Have you tried it with the texture pack? What about the doors with the pack?

        Without the new colours, the tiles do not look good at all, unless you paint them solid colours. There is a limit to what I can do to get other colours with these textures. The biggest gaain is to get orange and some of the darker colours, like dark red, purple etc.

        With the wood textures, it basically gives you new types of wood.

      I have deleted the furniture pack: Roof Tiles ETC.

      It is now again listed on Community Content. It took a few days after I uploaded it, but now it is at last available again. I am eager to see a few worlds use this. Let me know so I can download it and have a look at it. It seems that the furniture bug is not a problem anymore using tiles. Just remember that these tiles really need the more colours texture pack, otherwise the tiles are bright yellow. The survioval pack also gives more colours.

      Also, if you do like it, rate it. I don’t care about recognition. It is just frustrating to scroll down so much.

      My colour TV word has gone down again because of what Kaalus mentioned. For those who mentioned that the the world size is not an issue on Windows, since you have big drives, that is not the problem, Dropbox is the issue. Just read again what he posted.

    Kaalus, furniture is regarded as wood, even if you craft it from just granite or metal. I understand that it is almost impossible to know which furniture are flammable, float-able and which are not. Is it possible to rather mark it with high resistance to destruction and not flammable? Yes you will no longer be able to use tables and chairs as fuel, but that is ok. I am not sure how much resistance furniture has against lightning as well.

    I use roof tiles furniture and I do not want lightning to destroy it. It was created using granite, basalt, sandstone and clay.

    The problem I have, is that when my tiles are near a fireplace, they catch fire and my whole roof burns down, granite burning… Please help with this. You also cannot use furniture near a fireplace like with making a fireplace with furniture. The same will go with lava. Rather give it resistance, especially since it is mostly used in creative.

    I came up with a nice trick to have a fire place right next to flammable items like my roof tiles. Just make furniture of a torch and it looks like a fire, but doesn’t burn. Just remember that it also does not produce heat:

    interesting idea. but if the game can determine such a thing as complexity, then it could also easily calculate the ratio of burning materials, for example: a completely stone table is not fuel, and a chair half made of wood or diamonds will be two times shorter.

      The problem is with the amount of bits available for blocks, but more importantly the information used up to make a piece of furniture. It will leave you with less vectors to create furniture, meaning some complex furniture that was already created will have a problem, since there will not be enough place to store that information.

        Eh – furniture doesn’t work that way. It’s technically not a block like the others. They are defined in their own section in the project file. Kinda like a mini version of the chunks file. So adding characteristics to them does NOT increase the bits needed to define a block.

    Just remember that the tiles only work with Johan Real more colours marble or Survival, otherwise the tiles are bright yellow, not nice. The furniture pack is way down. It is rated high, but not many have rated it, maybe because of the reason I mentioned.

    I have also found a great way to have a fireplace that will not put my roof tiles on fire. Make furniture from one torch only. I looks even better than a block of coal, but it does not give off heat though:

      That’s a nice fireplace. I have had similar challenges making indoor temps warm enough and reducing danger of fire.
      One thing I like to do is find or make a coal block and light on fire with a (sulphur) match. If your house has stone walls and roof that will withstand the heat. I have sometimes surrounded the coal block with Gravel or with Stone Bricks and light just the interior face of the coal. Or alternatively, I’ll bring a bucket of lava and dump that in a one-block gap in the floor. The, to prevent accidental injury, put a half-height stone block on top.
      I have seen a fireplace that used dispensers to drop wood on an existing fire, but I thought that was not very realistic.

Just remember to use my more colours or survival texture packs, otherwise the coloured tiles are bright yellow. You can also use the remove paint bucket to have sandstone tiles. I have used this roof on a house in my Colour TV world.

    I have added outside corners so that you can make roofs like these:
