3DWalker - 3D Environment explorer for Unity3d Projects

Unity3d is one of the most popular game-engine use for game development, simulation, training and architecture visualizations. In most 3D projects, specially related to architecture, simulation and training, we require feasible, friendly, effective and robust methods to navigate in the 3D environment. In unity, we use cameras for rendering and exploring 3D world and usually navigate camera in order to show or explore the 3D environment. Conventionally, we develop and use different kind of cameras like Fly camera, Walk camera, Orbit Camera, Point Camera etc. These camera are use to watch and navigate 3D projects.

There are plenty of paid and free solution available that provides easy ways to run your 3d projects with different cameras. But there is a general requirement to develop such a workspace (or working environment)  that help every newbie or expert unity developer to quickly set and play unity project. The workspace should be developed and form over some main principles like effective navigation systems, intuitive UI and run-time 3D object manipulation and multi language support. For this reason, I have just stared an open source project named 3DWalker at GitHub with these aims & objective. Obviously, the aim of 3DWalker is to improve user experience regarding 3D world navigation with bunch of other features like 3D environment manipulation at run-time. All Unity3d developers are allow to participate in this project so together we can provide better 3D experience to over end-users.

Since Unity 2020 (I think!) exists something called Focused Inspectors: open as many inspectors as you want by right-clicking a group of GameObjects and/or Assets then selecting "Properties"! 🥳https://t.co/oUiGOo6jDj@unity3d #unitytips #gamedev pic.twitter.com/71UPU4EHXV

As far as #unitytips go this ain't flashy, but is one of my all-time faves

Empty game objects. The problem? They're invisible. Easy to forget and lose in the scene view. Oh no!

The answer? Give them an icon. Your life will be a million times better and so will mine thankyou pic.twitter.com/yf1FZM0X97

One thing i figured out to reduce the iOS App size of a unity game, is to set the compression to LZ4HC in the build setting, are there any other tips on reducing the app size? #unity #unitytips #IndieGameDev pic.twitter.com/DIpVgnfHif

— fleischshake (@fleischshake) April 17, 2020

To improve performance and reduce draw calls, try to use GPU Instancing if possible. It optimises copies of the same Mesh, useful for repeating objects like grass, but allows for different parameters so doesn't have to look identical.https://t.co/TQXwrwUwMD#unitytips #unity3d

With the latest @unity 2020 LTS you can use some of the new features in C# 8.0! One of my favorites is a switch expression which greatly reduces the syntax required. It's not a full replacement for switch statements but works well for linking data together. #UnityTips pic.twitter.com/tAB3mxfxvN

Found a nice property attribute that labels array elements by enum names. This is going to be very useful, no more need to make get methods or dicts as I typically would when I want to map data to enum.

Data Saving Techniques for Unity3d Application

Data is one of the integral element in modern applications of Games, VR/AR or gamification. Unity3d, the most famous and most widely use game-engine provide you different options to save your game data in different ways. Once on a forum, a programmer asks the question that how to save data in unity3d?? and I  answered him with different options. I guess it is necessary to share the detail of the answer for future users. So, here is the list of different options for saving data for unity application. (we will like to update this article to add more techniques if you know anyone).

1. Platform-independent:

One way of saving data in Unity3D in a Platform-independent way is to use the PlayerPrefs class.


Here is the example to set a string and later get it through PlayerPrefs class.


Where the Data Store? Here is the chart:

Platform	Data stored at
Windows	Registry under HKCU\Software\[company name]\[product name] key
macOS	~/Library/Preferences folder, in a file named unity.[company name].[product name].plist,
Win Phone 8	application's local folder
WebGL	browser's IndexedDB
Linux	~/.config/unity3d/[CompanyName]/[ProductName]
Android	/data/data/pkg-name/shared_prefs/pkg-name.xml
	* company and product names are the names set up in Project Settings

Reference Links:

·         PlayerPrefas Documentation

·   Tutorial PERSISTENCE - SAVING AND LOADING DATA using DontDestroyOnLoad, PlayerPrefs, and data serialization Video Tutorial by unity.

2. Server Side:

You can also use a Server for saving data (like a combination of PHP and MySQL Database). You can use it to save Score Data, user profile, etc., Learn More From Unity Wiki
You can also use third party solution like back4App and firebase.

3. Embedded Database:

SQLite (an embedded database for your app) is another great option for you get the Free Package, it is simple and easy (and my favorite) if you know SQL.

Unity3d Training and Certification in Pakistan

 Unity3d, the amazing cross platform game-engine developed by Unity Technologies, helping thousands of users to develop games, simulations, architecture, gamification, VR, Mobile and Console applications. In April 2016, Unity announced it own certification program with this objective and background:

In talking with members in the Unity community, one of the common, recurring themes we have encountered is a need for a way to reliably assess an individual’s Unity knowledge and skills against a benchmark of proficiency.

In an effort to respond to all of these needs, we developed the Unity Certification Program, and at GDC 2016 we were thrilled to announce that the first level, Unity Certified Developer, is now available!

In order to make accessible its certifications in different countries,  Unity Technologies has partner with different training institutes. You can find its partner list here. Initially there was no affiliated partner exists in Pakistan but yesterday, i received an email from unity and I am pleased to share with you that, CETA has become the first and only Unity authorized institute in Pakistan.

"We are proud to announce our first Authorized Training Center in Pakistan: Center for Enterprise and Technology Advancement (CETA). You can now learn and get certified all at the same place!"

Now congrats for all Unity fans in Pakistan, CETA is giving Game Development Training in collaboration with Unity for the first time in Pakistan. Remember, its certification valid only for 2 years but  it is expected that it will teach you a lot as its course-ware seems comprehensive.

Unity3d Interview questions

Unity3d one of the famous and most amazing cross-platform game-engines that provides a great environment for game development. It is widely used and there are significant opportunities available for game development using this technology. If you want to avail these opportunities then, you must have to prepare yourself for technical questions and this is the reason for this post.

      After making some initial search and an interview experience, we have gathered some of the questions for you that you can consider before conducting or giving an interview as these questions addressing different aspects of unity game engine including programing, unity features and shaders etc. Remember this list does not include all the necessary questions. We will try to update this article in order to make a valuable resource. You can comment to share your interview question so that we can improve this source for our reader. In the future, we have also a plan to write the answer of these questions:
