# psn-js
|
|
js implementation of the [PosiStageNet protocol](https://github.com/vyv/psn-cpp/blob/master/doc/PosiStageNetprotocol_v2.03_2019_09_09.pdf)
|
|
|
|
|
|
## Install
|
|
`npm install --save @jwetzell/posistagenet`
|
|
|
|
## Usage
|
|
|
|
### Decode - [example](./examples/psn_client.js)
|
|
```
|
|
const { Decoder } = require('@jwetzell/posistagenet')
|
|
const decoder = new Decoder()
|
|
|
|
const buffer = Buffer.from('source PSN packets from somewhere')
|
|
|
|
decoder.decode(buffer)
|
|
|
|
// data from PSN Info packets
|
|
console.log(decoder.info)
|
|
|
|
// data from PSN Data packets
|
|
console.log(decoder.data)
|
|
|
|
```
|
|
|
|
### Encode - [example](./examples/psn_server.js)
|
|
```
|
|
const { Encoder, Tracker } = require('@jwetzell/posistagenet')
|
|
const encoder = new Encoder('Server Name', 2,3) //server name, version high, version low
|
|
|
|
const trackers = []
|
|
|
|
const tracker = new Tracker(1,'Tracker 1') // id, name
|
|
tracker.setPos(1.0,1.0,1.0) // x, y, z
|
|
|
|
trackers.push(tracker)
|
|
|
|
const timestamp = 1;
|
|
|
|
|
|
// these two calls return an array of Buffers due to potential splitting that might take place because of max UDP packet size
|
|
const dataPackets = encoder.getDataPackets(timestamp, trackers)
|
|
const infoPackets = encoder.getInfoPackets(timestamp, trackers)
|
|
|
|
dataPackets.forEach((dataPacket)=>{
|
|
console.log('send packet somehow')
|
|
console.log(dataPacket.toString('hex'))
|
|
})
|
|
|
|
infoPackets.forEach((infoPacket)=>{
|
|
console.log('send packet somehow')
|
|
console.log(infoPacket.toString('hex'))
|
|
})
|
|
|
|
```
