Unity WebGL Conversion Guide - Steps to consider For Unity Webgl Conversion

There are some common steps you need to repeat whenever you make Unity WebGL build or if you want to convert your project into WebGL. Beware I am not using Unity 2020.

1. Convert to Latest Unity Version (if Possible):

Always try to use the latest Unity version if you are building for unity WebGL as unity WebGL has several issues. With each new unity release, we see different bug fixes but remember each new build brings it known issues. If you don't have any problem with the latest unity version then, you should adopt it for your WebGL project. Beware porting to your current project into the latest unity version can show significant compatibility issues, so make a backup before conversion.

2. Save Scripting Define Symbols

Before converting to WebGL please save your scripting define symbol outside unity (separately). Scripting defines symbols will be available under player settings. Some of the symbols are lost during WebGL conversion.

A Glimpse of technical background of unity3d WebGL:

Unity support dozen of platform for application deployment and one of them is WebGL. WebGL allows you to run your content on a web. Technically, WebGL is an API that renders graphics in web browser. Currently, it has two supported version of WebGL 1.0 and 2.0. Remember WebGL 1.0 roughly matches the functionally of OpenGL ES 2.0 while WebGL 2.0 roughly matches the functionally of OpenGL ES 3.0.

Unity WebGL Structure

What is unity Render Streaming?

Unity render streaming is one of the packages/or a solution that allows HD rendering via a browser. For more clarification of the concept of render streaming, see the below video. Here you can watch that how we can access HD content into different devices (laptop, tablet or even mobile) via a URL. Remember, the processing will take place on one high-end PC while the different devices can get video streaming/audio or even get a remote control of the player.

This streaming solution work on top of WebRTC. WebRTC is a free and open-source project that allows RTC (real-time communication) between web and mobile applications. Luckily unity also provides its own render streaming platform called Furioos.

How to Setup Your Own Render Streaming in Unity3d

In the below video, I have explained how to setup your own render streaming.

Automatic MySQL Backup using Batch File on Windows

Backup of your database are important. You can do the backup manually but automatic backup with regular time interval are good and time saving. In this post I am specifically talking about Mysql. Unfortunately there is no free solution for auto Backup. So, There is a simple workaround available on windows platform to make MySQL backup automatically and freely. For this reason, you require a batch file and you have to write a batch script. And here are the steps for Mysql Database auto Backup:

1. Create a backup.bat file

2. Open the file in notepad and add this

echo off

start "" "C:\wamp\bin\mysql\mysql5.6.12\bin\mysqldump.exe(your my sql dump address)" --user root --password=(provide your db password here) databaseNameHere --result-file="D:\database backup location SqlFileName.sql" --database databaseNameHere

Now let's break down the string we have mentioned in the above file:

Post Processing and Unity WebGL

A common question asked several times about unity post-processing and WebGL, why post-processing is not working on my browser or some of post-processing features are not working in browser: The reason is that post-processing works with WebGL 2 (Unity Forum). Unity WebGL Post processing doesn't work on WebGL1. If your browser and GPU support WebGL 2.0 then PPS (Post Processing stack) should work within your browser. Unity Support graphics API WebGL 1 and WebGL 2 and if Graphic API settings are set to auto then WebGL 2 will try to run first (if supported in the browser) :

Remove Empty Unity Events - Do Empty Unity Events cause Performance Issues?

You definitely have noticed this thing that whenever you create a new script in Unity3D, the Unity scripting template adds two methods or unity events by default. The two methods are Start () &Update ().

using UnityEngine;
using System.Collections;

public class MyCustomScript : MonoBehaviour {

	// Use this for initialization
	void Start () {
	
	}
	
	// Update is called once per frame
	void Update () {
	
	}
}
