01. the Goal of the Independent Study

Mastering Unity Scripting and Networking

I was eager to learn and use the Unity 3D program to make games and some interesting works. So I decided to take the Independent Study and chose the subject of ‘Mastering Unity Scripting and Networking’. I know, It is not possbile to master the scripting and networking in just one semester. So I made some little games and VR / AR related projects.

One Unity game consists of many objects such as ; Game Scene, Player, NPCs (Non-Playable-Characters), Enemies, Winning-Losing Logic, Platforms (macOS, Windows, Android, iOS and more), UI/GUI design and components, 3D models, Sounds, Networking (If necessary), and scripting. I decided that not making 3D design and models on this class, be-

cause it is not included on my Independent Study. But, if possible, I would like to learn and master 3D modeling, texturing, animating on my nexxt semester.

Books and Online Resources

I bought Unity related books (Korean), and also bought e-books (English).

Here is the list ;

03. the 1st Project.

Unity Augmented Reality Game : Unity + Vuforia + Network + Projection

ing its shape and also moving around. Then I chose to use a projector.

phone. Therefore, I have to use the network to connect So the one for projection should be a notebook and also should take the server part.

2) Network Scheme Not all of its playing information should be communicated between these two devices. Only touch - kill information on the mobile should go to the server (notebook).

Then I need to find out which newtork method is appropriate for this project.

3) Prototyping I made two unity programs : one for the projection which was running on the notebook. another for the mobile to see the augmented image on itself and to interact on its image.

4) Networking There were 4 options to consider, and I tried every Step #03 technical methods : TCP/IP, UDP, Unity Network LobEvaluate the Prototypes by, Unity Network Manager.

It is easy to project on the fixed object.

04. the 2nd Project.

Unity Virtual Reality Game : Unity + Google Cardboard SDK

1) Project Sketch Virtual Reality is another hot media now, then I would like

the player is on the spot, then zombies are coming to the time, the zombies or one zombie stops or frozen temporarily. They will coming from all direction, so the player should look around and make the zombiles stop.

2) Unity : Programming & Designing

There is a book, ‘Unity Virtual Reality Project’. There is a very similar example project on the book, so I used the example project for this.

3) VR headset testing I put a iPhone 6+ into the VR headset. When I tested it

with the headset, I feel something interesting and fun.

4) iPad testing I also put the game into the iPad mini, and tested it

05. the 3rd Project.

Unity Mixed Reality Game : Unity + Lego + Projection

1) Project Sketch

Making a maze with Lego, then project the game on the maze. Then this becomes a physical maze + a digital game = the mixed reality game.

Make more Lego mazes : one lego on the desk, one drawing maze on the wall, one another Lego on the wall.

2) Lego + Unity 2D game testing Building a three-story building with Lego, and made a

simple 2D game with Unity. Then project the game on to the Lego building, and playing.

This kinds of game on mobile or computer is common,

but playing the character on the real object arise much interesting and actually I really felt fun with it.
