A Minecraft client running in a web page. **Live demo at https://webclient.prismarine.js.org/**
|
|
|
|
|
|
## How it Works
|
|
prismarine-web-client runs mineflayer and prismarine-viewer in the browser, which connects over WebSocket to a proxy
|
|
which translates the WebSocket connection into TCP to connect to normal Minecraft servers.
|
|
|

## Live Demo
|
|
Click on this link to open it in your browser, no installation necessary: https://webclient.prismarine.js.org/
|
|
|
|
*Tested on Chrome & Firefox for desktop platforms.*
|
|
|
|
## Usage
|
|
To host it yourself, run these commands in bash:
|
|
```bash
|
|
$ npm install -g prismarine-web-client
|
|
$ prismarine-web-client
|
|
```
|
|
Finally, open `http://localhost:8080` in your browser.
|
|
|
|
## Features
|
|
|
|
* Display mobs and players
|
|
* Display blocks
|
|
* Movement (you can move, and you see entities moving live)
|
|
* Place and break blocks
|
|
|
|
## Roadmap
|
|
* Containers (inventory, chests, etc.)
|
|
* Sounds
|
|
* More World Interactions (attacking entities, etc.)
|
|
* Cosmetic Rendering Features (day night cycle, fog, etc.)
|
|
|
|
## Development
|
|
|
|
If you're contributing/making changes, you need to install it differently.
|
|
|
|
First, clone the repo.
|
|
|
|
Then, set your working directory to that of the repo. For example:
|
|
```bash
|
|
$ cd ~/prismarine-viewer/
|
|
```
|
|
|
|
Finally, run
|
|
|
|
```bash
|
|
$ npm install
|
|
$ npm start
|
|
```
|
|
|
|
This will start express and webpack in development mode: whenever you save a file, the build will be redone (it takes 5s),
|
|
and you can refresh the page to get the new result.
|
|
|
|
Connect to http://localhost:8080 in your browser.
|
|
|
|
You may want to disable auto saving in your IDE to avoid constant rebuilding, see https://webpack.js.org/guides/development/#adjusting-your-text-editor
|
|
|
|
To check the production build (take a minute to build), you can run `npm run build-start`
|
|
|
|

Some variables are exposed in window for debugging:
|
|
* bot
|
|
* viewer
|
|
* mcData
|
|
* worldView
|
|
* Vec3
|
|
* pathfinder
|
|
|
|
### Some debugging examples
|
|
|
|
In chrome dev tools
|
|
|
|
* `bot.chat('test')` allows you to use the chat
|
|
* `bot.chat(JSON.stringify(Object.values(bot.players).map(({username, ping}) => ({username, ping}))` display the ping of everyone
|
|
* `window.bot.entity.position.y += 5` jumps
|
|
* `bot.chat(JSON.stringify(bot.findBlock({matching:(block) => block.name==='diamond_ore', maxDistance:256}).position))` finds the position of a diamond block
|
|
* `bot.physics.stepHeight = 2` allows you to walk about blocks
|
|
* `bot.physics.sprintSpeed = 5` walks faster
|
|
* `bot.loadPlugin(pathfinder.pathfinder)` then `bot.pathfinder.goto(new pathfinder.goals.GoalXZ(100, 100))` goes to position 100, 100
