A simple Minecraft clone written in C using modern OpenGL (shaders).

Craft

Minecraft clone for Windows, Mac OS X and Linux. Just a few thousand lines of C using modern OpenGL (shaders). Online multiplayer support is included using a Python-based server.

http://www.michaelfogleman.com/craft/

Features

• Simple but nice looking terrain generation using perlin / simplex noise.
• More than 10 types of blocks and more can be added easily.
• Supports plants (grass, flowers, trees, etc.) and transparency (glass).
• Simple clouds in the sky (they don't move).
• Day / night cycles and a textured sky dome.
• World changes persisted in a sqlite3 database.
• Multiplayer support!

Download

Mac and Windows binaries are available on the website.

http://www.michaelfogleman.com/craft/

See below to run from source.

Install Dependencies

Mac OS X

Download and install CMake if you don't already have it. You may use Homebrew to simplify the installation:

brew install cmake

Linux (Ubuntu)

sudo apt-get install cmake libglew-dev xorg-dev libcurl4-openssl-dev
sudo apt-get build-dep glfw

Windows

Download and install CMake and MinGW. Add C:\MinGW\bin to your PATH.

Download and install cURL so that CURL/lib and CURL/include are in your Program Files directory.

Use the following commands in place of the ones described in the next section.

cmake -G "MinGW Makefiles"
mingw32-make

Compile and Run

Once you have the dependencies (see above), run the following commands in your terminal.

git clone https://github.com/fogleman/Craft.git
cd Craft
cmake .
make
./craft

Multiplayer

After many years, craft.michaelfogleman.com has been taken down. See the Server section for info on self-hosting.

Client

You can connect to a server with command line arguments...

./craft [HOST [PORT]]

Or, with the "/online" command in the game itself.

/online [HOST [PORT]]

Server

You can run your own server or connect to mine. The server is written in Python but requires a compiled DLL so it can perform the terrain generation just like the client.

gcc -std=c99 -O3 -fPIC -shared -o world -I src -I deps/noise deps/noise/noise.c src/world.c
python server.py [HOST [PORT]]

Controls

• WASD to move forward, left, backward, right.
• Space to jump.
• Left Click to destroy a block.
• Right Click or Cmd + Left Click to create a block.
• Ctrl + Right Click to toggle a block as a light source.
• 1-9 to select the block type to create.
• E to cycle through the block types.
• Tab to toggle between walking and flying.
• ZXCVBN to move in exact directions along the XYZ axes.
• Left shift to zoom.
• F to show the scene in orthographic mode.
• O to observe players in the main view.
• P to observe players in the picture-in-picture view.
• T to type text into chat.
• Forward slash (/) to enter a command.
• Backquote (`) to write text on any block (signs).
• Arrow keys emulate mouse movement.
• Enter emulates mouse click.

Chat Commands

/goto [NAME]

Teleport to another user. If NAME is unspecified, a random user is chosen.

Implementation Details

Terrain Generation

The terrain is generated using Simplex noise - a deterministic noise function seeded based on position. So the world will always be generated the same way in a given location.

The world is split up into 32x32 block chunks in the XZ plane (Y is up). This allows the world to be “infinite” (floating point precision is currently a problem at large X or Z values) and also makes it easier to manage the data. Only visible chunks need to be queried from the database.

Rendering

Only exposed faces are rendered. This is an important optimization as the vast majority of blocks are either completely hidden or are only exposing one or two faces. Each chunk records a one-block width overlap for each neighboring chunk so it knows which blocks along its perimeter are exposed.

Only visible chunks are rendered. A naive frustum-culling approach is used to test if a chunk is in the camera’s view. If it is not, it is not rendered. This results in a pretty decent performance improvement as well.

Chunk buffers are completely regenerated when a block is changed in that chunk, instead of trying to update the VBO.

Text is rendered using a bitmap atlas. Each character is rendered onto two triangles forming a 2D rectangle.

“Modern” OpenGL is used - no deprecated, fixed-function pipeline functions are used. Vertex buffer objects are used for position, normal and texture coordinates. Vertex and fragment shaders are used for rendering. Matrix manipulation functions are in matrix.c for translation, rotation, perspective, orthographic, etc. matrices. The 3D models are made up of very simple primitives - mostly cubes and rectangles. These models are generated in code in cube.c.

Transparency in glass blocks and plants (plants don’t take up the full rectangular shape of their triangle primitives) is implemented by discarding magenta-colored pixels in the fragment shader.

Database

User changes to the world are stored in a sqlite database. Only the delta is stored, so the default world is generated and then the user changes are applied on top when loading.

The main database table is named “block” and has columns p, q, x, y, z, w. (p, q) identifies the chunk, (x, y, z) identifies the block position and (w) identifies the block type. 0 represents an empty block (air).

In game, the chunks store their blocks in a hash map. An (x, y, z) key maps to a (w) value.

The y-position of blocks are limited to 0 <= y < 256. The upper limit is mainly an artificial limitation to prevent users from building unnecessarily tall structures. Users are not allowed to destroy blocks at y = 0 to avoid falling underneath the world.

Multiplayer

Multiplayer mode is implemented using plain-old sockets. A simple, ASCII, line-based protocol is used. Each line is made up of a command code and zero or more comma-separated arguments. The client requests chunks from the server with a simple command: C,p,q,key. “C” means “Chunk” and (p, q) identifies the chunk. The key is used for caching - the server will only send block updates that have been performed since the client last asked for that chunk. Block updates (in realtime or as part of a chunk request) are sent to the client in the format: B,p,q,x,y,z,w. After sending all of the blocks for a requested chunk, the server will send an updated cache key in the format: K,p,q,key. The client will store this key and use it the next time it needs to ask for that chunk. Player positions are sent in the format: P,pid,x,y,z,rx,ry. The pid is the player ID and the rx and ry values indicate the player’s rotation in two different axes. The client interpolates player positions from the past two position updates for smoother animation. The client sends its position to the server at most every 0.1 seconds (less if not moving).

Client-side caching to the sqlite database can be performance intensive when connecting to a server for the first time. For this reason, sqlite writes are performed on a background thread. All writes occur in a transaction for performance. The transaction is committed every 5 seconds as opposed to some logical amount of work completed. A ring / circular buffer is used as a queue for what data is to be written to the database.

In multiplayer mode, players can observe one another in the main view or in a picture-in-picture view. Implementation of the PnP was surprisingly simple - just change the viewport and render the scene again from the other player’s point of view.

Collision Testing

Hit testing (what block the user is pointing at) is implemented by scanning a ray from the player’s position outward, following their sight vector. This is not a precise method, so the step rate can be made smaller to be more accurate.

Collision testing simply adjusts the player’s position to remain a certain distance away from any adjacent blocks that are obstacles. (Clouds and plants are not marked as obstacles, so you pass right through them.)

Sky Dome

A textured sky dome is used for the sky. The X-coordinate of the texture represents time of day. The Y-values map from the bottom of the sky sphere to the top of the sky sphere. The player is always in the center of the sphere. The fragment shaders for the blocks also sample the sky texture to determine the appropriate fog color to blend with based on the block’s position relative to the backing sky.

Ambient Occlusion

Ambient occlusion is implemented as described on this page:

http://0fps.wordpress.com/2013/07/03/ambient-occlusion-for-minecraft-like-worlds/

Dependencies

• GLEW is used for managing OpenGL extensions across platforms.
• GLFW is used for cross-platform window management.
• CURL is used for HTTPS / SSL POST for the authentication process.
• lodepng is used for loading PNG textures.
• sqlite3 is used for saving the blocks added / removed by the user.
• tinycthread is used for cross-platform threading.

craft's Issues

Show own text in chat buffer

Now that you don't see what you type in the console any more there is no confirmation what you said was received by the server. There is no longer any reason to distinguish between input and output text and every reason to treat them the same way.

How may I assist in debugging this?

A potential account system

It would be nice if there was an account system that would save our player's accounts, maybe password protect them, and hold our location (and potentially inventory in the future). However, it would be a huge pain to host a primary server to hold this info, and we do not want to reserve usernames on servers we will not ever go on. The solution is to make each server hold its own account data.

From the Command Line

If a user goes to connect to a server, there can be an additional argument for uesrname:

./craft <ip> <port> <user>

It would then ask for your password, like how the sudo command works on mac and linux.

From Inside the Game

You should also be able to join without a username, and play as a guest, and create an account with /user create <name> <password> <confirm>. While in the server, you could rename your account with /user rename <new name>, and change password with /user password <current password> <new password> <confirm>. Lastly, it would allow you to log-in and log-off your account with /user logon <account> <password> and /user logoff. We would also allow deletion of accounts with /user delete while logged in.

Why?

Beyond simple data storing, this would allow for a permissions-like interface by changing who could perform what actions as more get added on. We could also mess with the colors of names based on their permission-level.

Reduced Performance

Ever since Wednesday or Thursday, I've noticed a significant drop in fps on both my Mac and Linux boxes. It's really hard to enjoy now, as I'm only able to get 8 fps max with the latest files (also, multiplayer is literally unplayable, but that's a separate issue). The actual Minecraft runs way smoother for me, which wasn't the case when this project was first posted on Hacker News. Is anyone else experiencing this problem?

Multiplayer loading freez

Hi,

I have a huge freeze when connected to 199.115.118.225 16018.

I think this is caused by the internet connection.

Does anyone have this problem ? Is there something to do to avoid that ?

strdup isn't c99

Add -D_GNU_SOURCE or similar.

Allow specifying max chat messages to display

A setting to control the max number of chat message to display at a time would be nice, in order to preserve context and prevent messages being pushed out too soon in case of high activity.

Windows build fails

Compiler - MVS 2012

Allows only c89 standard which breaks code because of declarations not made at the beginning of block.
Used gcc with cygwin to get a successful build. But can anyone suggest an alternative for use with Visual studio

Add support for rendering text

This could be useful for migrating the current terminal-based chat to a partial/full in-game chat implementation. I've been looking at QuesoGC, @fogleman, what do you think?

recv: Bad file descriptor

Somehow the client received a bad file descriptor while connected to your server.

That's not very nice!

Dummy Mob

hi,

I tried to add a mob based on the player class but it is not displayed, probably due to some simple error. It would be nice to have some dummy mob added.

Read client settings from configuration file

I'd like to see (most of) the macro constants in main.c migrated to a separate file that is read at launch, possibly keeping the macros as fallbacks. From a developer perspective this has the advantage of allowing custom settings without Git complaining. From a user perspective it has the advantage of not necessitating repeated compilation as well as persisting client settings that can't reasonably be hard-coded (e.g. nick).

I'm willing to take a shot at this, myself, too, but only if @fogleman agrees with the merit and would be willing to integrate the changes (notwithstanding the quality of any implementation my unrefined skills could amount to). Some specifics would also need agreeing on:

• format
• file path
• desired settings
• documentation/communication

If I had to answer those questions I'd probably pick .ini; same directory as the craft binary; support as many settings as possible; and add a sample file containing all supported settings with their default values and as much additional documentation as possible. That file probably wouldn't be read by the client but simply serve as a reference or a starting point for personal configuration, because otherwise people may edit that file directly and then versioning becomes problematic again. I'm not married to any of those ideas, however. A more Linux-y approach would look for a dot-file in $HOME or something but that would be very un-Windows-y and I don't like that.

Some specific goals I would like to achieve with this:

• customizing video and keybind settings without triggering changes
• client side nicks (see #63)
• server aliases

Give access to foliage block

The foliage block used by trees does not seem to be available to players. This means we can't make Christmas trees.

Bug: Falling through blocks from a height

Weird bug:
In fly mode, if you drop straight down from a large height, you clip right through the blocks on the ground.

Also if you tab out of fly mode from a height, and drop straight down, pointing directly towards the ground, it clips right through.

Seems to be more easily repeatable if I connect to the server from two clients at the same time on my computer.

Grass growth texture is different color than grass block

See attached image.

Kill another dependency: GLEW

I just found an OpenGL load generator that can replace glew for loading modern OpenGL. It creates only one source and one header file, so it can be built right into the source. It would also allow the usage of up to OpenGL 4.4 (which isn't currently available on Macs, so you may have to go with 4.0 instead). You can also choose what extensions to load, and whether you want to implement extension loading as if you were using glew or glee.

Make Player color black/different

Players are the same color as clouds currently which makes it harder to differentiate. Could you change to a color not used by a texture currently

Including LibPng (or LodePng) as a Submodule

When trying to build it, I ran into the issue of it not finding png on my computer (OS X 10.9). I was wondering if it was a dependency, which is not listed on the read me.

However, libpng is hosted on github, so it may make sense to add another submodule for that, and save the trouble of installing dependencies for everyone.

If these make the build process too long, there is also the option of using lodepng, which is a single file png decoder/encoder.

Server has no clue what it's map looks like

I've been trying to program some stuff for the server lately, and it has come to my attention that the server has no way of knowing what the pregenerated blocks are. It can only tell which blocks have been placed/removed by clients. Hopefully there's a way to integrate the map.c code in python somehow, so the server can actually get block data.

Create full player body, instead of just a head

Players should have entire bodies, similar to on Minecraft, instead of just a head.

Enhancement: Including GLFW as a submodule

We would no longer have to download GLFW separately for it to work, it would become easier to set up and run, and it would always be up to date.

Set nick client side

Having to set nick on every connect gets irritating, but for persistent nicks, storing them server side isn't exactly scalable (storage, client identification, name collisions).

Ultimately I'd like to be able to set a nick client side, offline. Other than requiring changes to the server to support receiving nicks (I think it could just store at connect and /nick and mostly keep the current code) it will be necessary to decide how to handle collisions. Currently there is no regard for collisions. Pull request #62 prevents collisions but for obvious reasons doesn't address the situation where a collision occurs when a client connects. The simplest solution, outside of continuing to disregard collisions, may be to assign the offending client a default name similarly to what happens now.

Crashes when trying to use multiplayer

Using the latest git I get

./craft 199.115.118.225 16018

Add a LICENSE.md

I suggest something open-source, to stir mods and improvements to the code. This is awesome!

Server is implemented in Python

I guess I love Python as much as you.

But I also guess that statement like "Minecraft clone in 2500 lines of C - even supports multiplayer online" might be a little misleading when server is actually written in Python.

Support text wrapping

Long lines extend beyond the screen. They should wrap.

Key bindings are broken with a dvorak keyboard

Need an indicator for the active observer mode

There is no way to tell which observer mode is active. It gets confusing sometimes, e.g. when the player you have been observing disconnects.

Block selection is off

When deleting or placing a block, the selected block is sometimes off from what it should be. See the pictures for examples.

Hangs on Q since text update

Up until the text update a few hours ago I've always gotten a recv: something-something error message when pressing Q to quit, but quitting has otherwise worked fine, including after the generic chat update. Since adding text support, which otherwise appears to work fine (there was no one to chat with :() the game hangs after pressing Q or releasing the mouse and closing the window with the X (though I don't know if that worked before), necessitating a manual shutdown.

I'm on Mint 16 but also in a VM, which is causing some other issues (reversed window context).

I don't have any time to look into this right now, just reporting it.

Server is written in Python 2

Updating the server to Python 3 seems like a good idea- SQLAlchemy supports it, so there is nothing preventing it from happening.

I am more than happy to port it and tidy some code, I just can't test it as I am also afflicted by #16 .

Can't ascend or descend while strafing

Aimed up or down, strafing while moving forward or backward will not change your elevation. Moving without strafing will.

Bump speed of the user up to 200, and you can clip through the world

main.c: float speed = flying ? 200 : 5;

Can now fly through the ground. Perhaps it'd be good to do hit testing on the line that the user moved, rather than the client's position at the current frame?

Create a logging bot of some sort

There should be an official log bot for the Craft server mentioned in the README. Given that the client and server communicate using a very simple protocol, this shouldn't be too difficult.

The other side of glass isn't correct

See this: http://i.imgur.com/hiCLMUZ.jpg

Not sure how to reproduce this issue; it only happens on one side of the glass. This can be found on your server, near the large dirt penis structure.

Destroying Block under your feet freezes screen

Ubuntu 13.10 with Gnome and an NVidia card, more details on request, don't know what's helpful.

This helped to get back to a working desktop:

$ killall craft
$ /etc/init.d/x11-common restart

Closing the game freezes the window when connected to a server

I'm pretty sure that this is caused by line 118 of client.c. client_stop is called when the game is shutting down, but recv_worker uses an infinite loop, and will never terminate. So, when client_stop calls thrd_join, it will block forever waiting for a thread that will never finish.
