TRANSLATORS NEEDED If you want to help us translate pixelplanet.fun, look into i18n
Just to the 2nd anniversary of r/space, pixelplanet takes pixelgames to a new level. Place pixels, create pixelart and fight faction wars on pixelplanet.fun. Pixelplanet is a 65k x 65k large canvas that is a map of the world and can also be seen as 3d globe, you can place pixels where ever you want, build an island, take over another country with a flag or just create pixelart. 30 well chosen colors (decided by polls within the community) are available and you can place a pixel every 3s on an empty space, and 5s on an already set pixel. But pixels can be stacked up to a minute, so you don't have to wait every time.
Pixelplanet receives regular updates and launches events, like a zero second cooldown day on r/place anniversary. We are driven by our community, because placing pixels is more fun together.
Controls:
W, A, S, D, click and drag or pan: Move
Q, E or scroll or pinch: Zoom
Click or tab: Place Pixel
- nodejs environment
- Linux or WSL if you want to be safe (we do not build on Windows and therefor can't guarantee that it will work there)
Checkout repository
git clone https://github.com/pixelplanetdev/pixelplanet.git
cd pixelplanet
Install packages and build
npm install
npm run build
All needed files to run it got created in ./build
Notes:
-
If you run into problems, make sure that you have rights to g++ (if not, run as root and then chown username:username -R . after build)
-
If
npm installfails with "unable to connect to github.com" set:
git config --global url.https://github.com/.insteadOf git://github.com/
- nodejs environment with npm
- pm2 (
npm install -g pm2) as process manager and for logging - redis as database for storìng the canvas
- mysql or mariadb (setup own user and create database for pixelplanet) for storing additional data like IP blacklist
Configuration takes place in the environment variables that are defined in ecosystem.yml

Notes:
- to be able to use USE_PROXYCHECK, you have to have an account on proxycheck.io or getipintel or another checker setup and you might set some proxies in
proxies.jsonthat get used for making proxycheck requests. Look intosrc/isProxy.jsto see how things work, but keep in mind that this isn't neccessarily how pixelplanet.fun uses it. - Admins are users with 0cd and access to
Admintoolsin their User Menu for image-upload and whatever - You can find out the id of a user by looking into the logs (i.e.
info: {ip} / {id} wants to place 2 in (1701, -8315)) when he places a pixel or by checking the MySql Users database - If you use gmail as mail transport, make sure that less-secure apps are allowed to access it in your settings here
| Variable | Description |

Canvas specific configuartion like colors and cooldown is in canvases.json for all canvases. The titles and descriptions of the canvases are also in src/canvasesDesc.js for translation reasons. Changing them requires a rebuild.
Meaning of some values:
| Key | Description |
|---|---|
| ident | Unique character used in the url |
| title | Title |
| size | canvas size, power of 4 and between 256 and 65536 |
| bcd | Base cooldown for unset pixels |
| pcd | Cooldown for placing on set pixels |
| cds | Stack time of Cooldown |
| cli | Number of colors on the palette to ignore |
| ranked | If pixels on canvas count on player statistic |
| req | requieremt to place on the canvas |
| sd | Start-date of the canvas for historical view |
| desc | Small desctiption text |
| v | If 3D voxel canvas (boolean) |
| hid | Hidden canvases, can be just seen by pressing P |
The canvas size limit can be surpassed by changing the websocket packages in src/socket/packages/ to send chunk coordinates in 16bit.
req is an integer and if >0 is the amount of total pixels placed before being allowed to play there, if -1 it has no requirement and if 0 it is limited to registered users.
The colors that are ignored via cli are used for making the canvas (blue ocean and white continents) and to know if the pixel is already set by a user or not.
If you want to add a new canvas, be sure that you additionally create public/loading${canvasId}.png, public/assets3d/normal${canvasId}.jpg, public/preview${canvasId}.png and public/assets3d/specular${canvasId}.jpg, check out the existing ones to see what those files are for.
The default configuration values can be seen in src/core/config.js and for the canvases in src/core/constats.js
To add more css styles, create a new css file in src/styles based on src/styles/default.css with a filename beginning with "theme-" and rebuild`
- Make sure that mysql and redis are running
- Start with
pm2 start ecosystem.yml
Notes:
- pixelplanet uses the unix command sendmail for sending verification and password reset mails if no GMAIL account is given. If you are on windows, this might not work.
General logs are in ~/pm2/log/, you can view them with
pm2 log web
you can flush the logs with
pm2 log flush
Pixel placing logs are in ./log/pixels.logand proxycheck logs in ./log/proxies.log in the directory where you start pixelplaent. They get rotated daily and deleted if >14d old.
pm2 stop web
In order to get the real IP and not use the cloudflare Proxy IP for placing pixels, we filter those out. The cloudflare IPs are in src/utils/cloudflareip.js and used in src/utils/ip.js. If for some reason cloudflare ads more IPs to it, you can see them at https://www.cloudflare.com/ips/ and add them. If you use any other Reverse Proxy, you can define it's IPs there too.
If USE_XREALIP is set, we take the IP from the X-Real-Ip header without checking for cloudflare IPs. Use this if you have pixelplanet running behind nginx use the nginx set_realip module to give us the client ip on the X-Real-Ip header. And be sure to also forward X-Forwarded-Port and set X-Forwarded-Proto.
To have the canvas with all it's components autostart at systemstart,
enable mysql, redis (and probably nginx if you use it) according to your system (systemctl enable ...)
And then setup pm2 startup with:
pm2 startup
(execute as the user that is running pixelplanet)
And follow the printed steps if needed. This will generate a systemctl service file /etc/systemd/system/pm2-pixelplanet.service and enable it. You will have to run pm2 save while the canvas is running to let pm2 know what to start.
To make sure that mysql and redis are up when pixelplanet starts, edit this service file and modify the lines:
Wants=network-online.target
After=network.target mysql.service redis.service
PixelPlanet includes a backup script that creates full canvas backups daily in the form of PNG tile files and incremential backups all 15min (or whatever you define) that saves PNG tiles with just the differences since the last full daily backup.
It requires a second running redis instance.
The backup script gets built when building pixelplanet and also gets copied to build/ directory. You can run it with:
node backup.js REDIS_URL_CANVAS REDIS_URL_BACKUP BACKUP_DIRECTORY [INTERVAL] [COMMAND]
Make sure to get the order right, because the backup redis instance will be overwritten every hour. Interval is the time in minutes between incremential backups. If interval is undefined, it will just make one backup and then exit. If command is defined, it will be executed after every backup (just one command, with no arguments, like "dosomething.sh"), this is useful for synchronisation with a storage server i.e..
Alternatively you can run it with pm2, just like pixelplanet. An example ecosystem-backup.example.yml file will be located in the build directory.
Note:
- You do not have to run backups or historical view, it's optional.
Hourly event is an MMORPG style event that launches once in two hours where users have to fight against a growing void that starts at a random position at the main canvas. If they complete it successfully, the whole canvas will have half cooldown for a few minutes.
Pixelplanet is able to let the user browse through the past with those backups. For this you need to define BACKUP_URL and BACKUP_DIR in your ecosystem.yml for pixelplanet.
BACKUP_URL is the URL where the backup folder is available. It's best to let another server serve those files or at least use nginx.
BACKUP_DIR is the full path of the local directory where the backup is located (whats set as BACKUP_DIRECTORY in the command of the backup.js).
If v is set and true for a canvas in the canvas.json, it will be a 3D voxel canvas. 3D Canvases can not be seen in Historical View.
Run npm run lint:src to check for code errors and warnings or npm run lint -- ./your/file.js to check a single file.
Please do not produce too many additional warnings.
ttag is used for handling translations. For server-side rendering the Accept-Language header gets checked and the first locale used and on-the-fly translated (src/core/ttag.js provides the functions for it). On the client-side a seperate bundle for every language gets provided.
To update the language definitions in i18n/template.pot and i18n/template-ssr.pot run
npm run extract
You can use npm run babel-node ./your/script.js to execute a script with local babel.
npm run upgrade can be use for interactively upgrading npm packages.
