Minecraft Enterprise and 16-Bit ALU 151

tekgoblin writes "Joshua Walker spent the last few months creating a masterpiece. He created the Starship Enterprise 1701-D from Star Trek: The Next Generation in Minecraft using just blocks. He recorded a short video of him explaining how he did it and even gave us a sneak peek at the partially completed ship." He also posted on the Penny-Arcade forums about how he did it. If you aren't impressed by that, perhaps you should check out a 16-Bit ALU also implemented in Minecraft which totally reminded me of one of my favorite XKCD comics.

    First minecraft was plugged from the teamfortress.com blog, then 2 days of penny arcade were devoted to it, and since then it's been coming up every few days on slashdot and Boing Boing. The servers have been wrecked like 40% of the time from the constant barrage. If you like minecraft stop telling people about it!

            There's a tool that you can produce in the game called redstone dust that you can use to make what's basically wires, and it's the way it works makes it possible to create logic gates and such, which are the building blocks of computing. It's not a particularly efficient way of computing, but it can certainly be functional.

          The purpose of the electrical stuff was obstinately for much simpler reasons: Control of in-game elements. Doors open/close when powered, power can set off explosives and alter the direction of mine cart tracks. You have buttons and levers and pressure plates to provide temporary power and the red torches provide constant power unless powered themselves.

            Sadly, a computer requires something other than simple boolean logic, predictable timing.

            I spent 30 minutes building a simple 2 bit alu but I gave up building it in minecraft after 3 hours. The main issue is that everything runs in this global clock cycle. Evey torch you have in a path acts as a "tick" You also have to have a torch evey 15 spaces for a "refresher" so your putting down an inverter Evey 15 spots.

              They DON'T come out at the same time. That's plainly evident in the video. It's not clear if the thing even has a clock generator.

  • Discovered this game a few days ago. Have amassed a few items in survival mode, and have found a good hiding place, and buried them. This morning I snuck into someones home and stole a chest of items. Sitting at work now, I feel like I've actually stolen something from a local shop(not that I ever have). And thats the point, the game offers something so fresh. Tonight I could find my items raided.

    This is survival multiplayer, not the free-build mode, which does not appeal to me at all.

Some of the locations include Lua Beach, Torvalds Torrent, FreeBSD falls, and Xen caverns. We also have logic gate fields, where members are working on a binary adder. Working already are various logic gates. One of our members built tux out of blocks (who also doubles as a water slide!).

    • Voxels are, well, 3D pixels, pixels with volume. There's some good reasons to want to use them and a few games were big on the idea. However GPUs don't handle them, and thus their use has mostly died. However I think that's how this game builds things. That means they have to be pretty large, to function at a reasonable speed. If all the voxels got real tiny your CPU would die under the weight of all the calculations.

        The free version is basically just a demo of the engine. In the paid version it's called the creation mode. There are no gameplay elements in it. It's just a sandbox. There are other modes in the paid version like survival and multiplayer survival that add stuff like collecting resources, crafting items and fighting monsters among other things.

      • They're all in Java. The freely available version played in your web browser sucks and isn't at all representative of the fun you can have with the real game (though note that it's still in alpha and very buggy).

      • by khchung (462899)

        There is nothing to actually "play" in free version, which is basically just a world builder. In the paid version, there is a "survival mode" that actually has stuff like hitpoints, crafting, reason for building your house/base, mining, farming (if you like to), exploring, etc.

        I highly recommend the YouTube series "X's Adventure in Minecraft" http://www.youtube.com/watch?v=4bh4EexJO4I&sns=em [youtube.com] for a good idea why this game can be fun.

      • by FiloEleven (602040) on Tuesday September 28, 2010 @11:04PM (#33730848)

        I have only played the single-player mode in Minecraft Alpha. It's hard to describe exactly what makes it so compelling. The best thing i can think of is its sense of adventure.

        You're dropped into a randomly generated world with nothing but your fist. The terrain generator makes these fantastic landscapes that, while not always entirely Earthly, are usually quite engaging and natural: forested rolling hills, rocky islets, mountains with waterfalls (which have effective and consistent physics)...and dark foreboding caves, sometimes a small hole in a hillside, other times a straight-down pit you almost have to fall into to see. You never know what you'll find just over the next rise.

        It's up to you to bootstrap your survival. You've probably seen the Penny Arcade comics, so you know the basics: punch a tree, get some wood, craft some tools. You'll want to find some coal for torches and make a safe house before it gets dark--that's when the monsters come out. And because the combat is so basic, the outcome of every mob encounter is always in question. Zombies aren't so bad, but skeletons, spiders, and the sneaky creepers can ruin your night pretty quickly.

        It's a sandbox game, but it's also a little like Sim City or even an RTS: if you want to build stuff, you first have to collect the resources to do so. Any block can be removed from the game world, provided you have the right tools, and any block you've gathered can be placed wherever you like. Iron ore can be smelted (after you've crafted a furnace) into better tools; there's also rarer stuff like gold ore and diamonds the further down into the earth you go.

        And that's where Minecraft really shines: down in the caves. You'll find mazes of twisty little passages, all alike. You'll find huge rooms with water- or maybe even lava-falls in them. You may come to a dead end with a dirt wall; dig your way through it and you might discover a whole new set of tunnels. Wherever you go down there, you'll need to light your way with torches. Not only do they let you see pitfalls and baddies, but their light keeps more monsters from spawning. I have never played a game where the darkness was so fear-inducing. It's surprising just how tense I get when I have a pocket full of ore, but I'm lost deep below the surface, running out of torches, and my last pickaxe and sword are almost busted. Conversely, the rush of happiness and sense of reward if I survive and find my way to daylight is just as magnified.

        So there's that sense of adventure, and there's also room for lots of individuality. There is no in-game map to hold your hand, and there are as many methods to (try and) keep yourself from getting lost as there are players. I play on a MacBook Pro, meaning my render distance is pretty short, so I tend to use trails of torches above-ground to lead me from my fort(s) to working caves. Inside the caves I'm working out a system of double and triple torches in various configurations to keep myself oriented. Other people build arrows out of cobblestone or dirt, or wall off certain branches for later, or heaven knows what else. You're forced to deal with the challenges the game world throws at you, but you can do it however you like. What's the point besides exploration? Well, you can build a minecart roller coaster or a giant Sphinx, or just a homey little cottage. Whatever you build is entirely individual, since as you say you're basically working with big-ass voxels. I like expanding my houses sometimes, but the real fun for me is in the exploration.

        Oh, one more thing. The game is currently in Alpha. It has no right being even mildly playable, and instead it's the most engaging game I've played in a long time--in fact I can't remember the last time I was up until 5:00 AM playing a game before this. When Survival MultiPlayer starts to come together (it's playable but players and mobs can't deal damage yet) it's going to be a big deal. I'm having so much fun in my own worlds, I can only imagine what it'll be like exploring with a group of friends.
