Parsing of TF2 demo files in node.js and the browser
usage
cli
node bin/analyse demo.dem
api
var Demo = require('@demostf/demo.js');
var fs = require('fs');
fs.readFile("example.dem", function (err, data) {
if (err) throw err;
var demo = Demo.fromNodeBuffer(data);
var analyser = demo.getAnalyser();
var head = analyser.getHeader();
console.log(head);
var body = analyser.getBody();
console.log(body.getState());
});
more information from packets
Using the javascript api it's possible to get far more information out of a demo
file than the basic state provided by the cli interface.
var Demo = require('@demostf/demo.js');
var fs = require('fs');
fs.readFile("example.dem", function (err, data) {
if (err) throw err;
var demo = Demo.fromNodeBuffer(data);
var analyser = demo.getAnalyser();
var head = analyser.getHeader();
var match = analyser.match;
for (const packet of analyser.getPackets()) {
// where you can either get information directly from the packet (see ./src/Data/Packet.ts)
// or use the `match` object which has contains an (incomplete) state of the match at the current tick
}
});
A note on POV demos
During the development of this project the main focus has always been on parsing
STV demos.
Although there are currently no known issues iwth POV demos parsing them is a lot more error prone.
