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 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.
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:
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) :
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 ().
usingUnityEngine;
usingSystem.Collections;
publicclassMyCustomScript : MonoBehaviour {
// Use this for initializationvoidStart () {
}
// Update is called once per framevoidUpdate () {
}
}
Welcome to another unity game development tutorial, today i will show you how to render your whole scene or game in grey scale mode. Gray scale mode help you to
I have posted and gather several UnityTips and tricks into my blogs and youtube channel and in this post I again collecting all the links. Most of the tips are targetting beginners game developers. So here is the list without particular order:
I mostly prefer to tween UI but in this video i will show you how to animate text in Unity3d. most of the time you have to show some animated text and this game development tutorial exactly addressing the ui animation.
In this unity game development tutorial you will learn how to control decrease or increase GameObject transparency/alpha or opacity. With the help of a slider and a C# script. I will explain how to increase or decrease opacity of an object using a c# script.
Unity MonoBehaviour offers different magic events that you can attach to any GameObject. In this unity tutorial I will explain awake or start events as they both mostly use for assignment purposes.
Awake:Awake is invoked when the
MonoBehaviour is created. You may view it as your default constructor
Start: Start event executes after all initialization is done and the
first frame for the behavior is about to run. Start runs right before the
Update event.
Similarity:
Start/Awake are called exactly once
in the lifetime of the script.
Calling one method of a script from another script is common in Unity3d game development. In this Unity3d beginners tutorial I will show you how to call one c# method from another script.
In this video tutorial I have explained how to add third party logging system in Unity3d. This is advance logging way to log information in unity console with SeriLog. you can even write your games logs in specific text file with proper text formatting.
You often require to add third-party dll or nuget packages in Unity3d project. In this unity tutorial I will show you step by step how to add Nuget Package or dll into Unity3d project. For this tutorial we choose newtonsoft nuget package. You can adopt these steps for any nuGet package.
Here are the details,
go to your desired NuGet package webpage.
on the right side **Download Package** option click it.
your package **.nupkg** file will be downloaded.
change its extension to .zip and extract it
go to lib and copy your package dll file from net or any netstandard folder. For [your unity project compatibility purposes][2] view this:
In this post, we will learn that how to install and use Kafka server along with producer and consumer clients message exchange. This guide is based on practical only (no theory). For theory you can see other resources. This is the step by step practical guide that how to run Kafka on windows environment.
Step 1: Download and Extract Kafka in your desired directory:
1. Go to the link Apache Kakfa download and download. (I have download binary version 2.13)
2. Extract the .tgz file into any suitable location.
I have extracted my Kafka installation into C drive insdie Apachekafka Folder.
Step 2: Install Java run-time and Save its path in environment variable.
2. After installation, open Environment variable from my computer properties and add JAVA_HOME variable and provide your java runtime installation path.
Java runtime installation path provided in a new environment variable named JAVA_HOME.
3. In environment variable, select path, click on edit button and add this string “;%JAVA_HOME%\bin”
4. Go to command line and test "java -version". If you are not getting java installed version then see
Note:In above batch file command, kafka_2.13-2.4.1 is my Kafka installation folder name put your folder name in both location.
Two batch files have created in order to run Zookeeper and Kafka Server. Whenever you want to run Kafka server, you first need to start zookeeper server.
Step 4: Create A Topic
In order to send message from Producer to consumer, you first need to create a topic. Later both producer and consumer will subscribe the topic and send and receive messages.
1. Go to Kafka installation directory, then Bin\Windows, and open command prompt form here and type below lines. You can write your desired name instead of YourTopicName
Unity Vector graphic package is in the preview stage currently so you need to check one more setting in order to view the package in the package manager window. First of all, you need to open package manager window from the Window menu then click on advanced setting and check show preview packages.
During my extensive interaction with unity WebGL, I found different things that are difficult to handle in unity WebGL or Unity Webgl has some serious limitations (But nevertheless I have managed to stream large 3D area in unity WebGL with asset bundles). I have made this post in order to show you Unity3D WebGL issues sheet and if you are interested to see what technologies or toolchain Unity WebGL using behind the Scene then check this post. So, without a particular order here is the list of unity webgl limitations with relevant references for your further research.
1. You cannot use Threads in unity WebGL. Here is the error that you will get when thread try to start: SystemException: Thread creation failed. UnityLoader.js:4 at System.Threading.Thread.StartInternal (System.Security.Principal.IPrincipal principal, System.Threading.StackCrawlMark& stackMark) [0x00000] in <00000000000000000000000000000000>:0 GameDev Question Unity Forum Unity Webgl Doc
Update:Unity claim that in Version 2019.1.0 they have added multiple Multithreading support but it was not working according to my test and now I also find this that there was bug with the problem which has fixed in Unity 2020.1.0 and Unity 2019.4.7 (untested)
2. If you are continuously pressing any keyboard input key and meanwhile you lost focus to WebGL canvas in the browser, the input will still work even after releasing the key. The situation may get worst in the Edge browser.
Ref: SE Question Maybe resolved in Unity 2019.3.0 but I have tested and still the same problem is happening.
#UnityTips You can create artificial fog for a low-spec project by fading out an object's alpha (this was created using Shader Graph) and using a blank skybox.
For debugging purposes, you may require to pause the game on an error so that you can inspect the game situation. For this reason, you can follow these steps:
1. Write an error log in block of the code
Debug.LogError("Exception occured");
And before running the editor open console and hit Error Pause in the console log.
The game will pause as any error occurred in the console.
