Porting a desktop unity application to a webgl build

Porting to WebGL in Unity3D

Porting from Desktop / UWP to WebGL comes with a lot of challenges. When I ported an application, there were many libraries and code which didn't work on WebGL. However, I found alternatives and were able to switch libraries to make it work in WebGL.

Not supported features

  • System.Net namespace
  • Threads are not supported (System.Threading)
  • No Multithreading
  • No direct access to socket
  • Reflection using System.Reflection.Emit

Audio codecs: AAC
Latency: 2 - 30 seconds

Pros: Multicast support, low buffering, wide platform support
Cons: Old codecs, somewhat low security, relatively high latency

WebRTC: Web Real-Time Communication (both UDP and TCP)

simple ftp server using user list and /var/www/{user} directory
# Config file /etc/vsftpd.conf using userlist and /var/www/{user} directory
#
# The default compiled in settings are fairly paranoid. This sample file
# loosens things up a bit, to make the ftp daemon more usable.
# Please see vsftpd.conf.5 for all compiled in defaults.
#
# READ THIS: This example file is NOT an exhaustive list of vsftpd options.
# Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's
# capabilities.

Unity Addressables

Unity3D Addressables

Addressables are a new feature by Unity3D to allow the loading of an asset by a simple address no matter whether it is stored locally or remotely. Required assets are loaded at runtime which can reduce build time, installation size and Unity Editor play times. It can also be used to deliver content for deployed games and applications.

However, the setup and the content update after you deployed your game / application can be challenging.

The manual is found here: https://docs.unity3d.com/Packages/com.unity.addressables@0.6/manual/index.html
