Nginx config and ubuntu systemd services for hosting multiple game instances on ports 8001 through 8005, proxied from urls like wss://subdomain.domain.io/1 through wss://subdomain.domain.io/5; can also remove the ssl and listen on port 80 instead. The service file is an example, but creating 5 called instance1.service through instance5.service a…

timetocode / transfer-example.js

Created June 1, 2019 19:37

Example of transferring a player between two nengi instances while maintaining an authoritative server. One instance registers some information with the other instance, and provides the client with a token which it uses to be reconnected with that information after connecting to the other instance.

	// pseudocode for transfers if game has a practically infinite number of instances.
	// From one of the game servers
	transfer(client, toInstance) {
	toInstance.someWebApi.request(
	{ transfer: { token: 'abc123', data }},
	(res) => {
	if (res.transferAccepted) {
	instance.message(new TransferMessage(address, token)), client)
	client.disconnect()
	}

timetocode / PlayerCharacter.js

Created June 1, 2019 06:14

babylon.js + nengi.js entity example. Note: one can write the same thing in more of an ECS style (instead of regular oop) if desired by moving all of the methods off of PlayerCharacter and into systems

	import nengi from 'nengi'
	import * as BABYLON from 'babylonjs'

	class PlayerCharacter {
	constructor(scene) {
	this.name = 'anon'
	this.mesh = new BABYLON.Mesh('dummy', scene)
	this.mesh.entity = this // for collisions within babylon
	this.hitpoints = 100
	// velocity from own impulses

Created October 17, 2018 01:00

Example of using tls-json + express to create a master server listing service. master.js uses tls-json to listen over tls and accept connections + listing data from other services that connect, meanwhile instance.js shows a snippet of a game server that is listing itself on the master server. server.json is an example of what the http call to th…
