DSC RNGPIT had organized a session on Game Development where students where introduced to the basics of Game Development and the Unity Game Engine Interface. Students were also introduced to the game development flowchart where an example of Flappy Bird was given, and were also given a task to make flowcharts for their games.

1. Game Development
Getting Started with

2. The overall process of making a game is called Game Development.
This “overall” process consists of thinking of a game idea, compiling your ideas
into a document for better understandability, actually making the game,
polishing your game, making your game available to the public.
In the previous point, the actually making a game, takes the most of the time.
The rest of the processes are just for understanding your game better.
Let’s see all the processes in brief.
What is Game Development?

5. How do we do it?
When games were created in the “old-times”, they used to create every pixel on
the screen by themselves, every logic for moving a pixel was written by hand.
Now all these tasks are very tedious, so the developers came with something new,
where a program manages all the stuff for you, and you can just focus on creating
the logic of your game.
These programs are called Game Engines.
Game Engine is a very powerful and helpful tool which helps you in making games
by not letting you worry on the basic stuff that just repeats every time for a new
project.

7. Unity Game Engine Introduction
WHAT?
A game engine where you can create desktop, mobile, console, interactive
games.
WHAT CAN YOU MAKE?
2D / 3D games , AR / VR games/content.
WHY? -
● Easy to Learn for beginners
● Free and powerful tool
● Biggest Community Support
● Build support for almost 30 platforms, including Mobile, Desktop, Web,
Consoles, Virtual Reality, AR.

8. Unity Interface Introduction

9. Session 2

10. Unity Terminologies
GameObject - An object which is in your game.
Components - Components define the behaviour of the gameobject. A gameobject
can have different types of components attached to it.
Prefab - A gameobject which is needed multiple times can be made into a prefab in
Unity and can be reused multiple times.
Script - A piece of code that drives your gameobject.
Asset - Things that make up your game are called Assets

11. Classes that make up Unity

12. Unity C# Script Structure

13. How does Unity work?

14. Game Flow / Game Loop
Before we start making games, we should know what our game does.
We must define a game flow for our game, or something that shows that our game
is running. For eg. Temple Run, How do you know that it is still running?
Unity uses the Update function for defining all the game loop related code.
And Start/Awake for initializing your game.
Let’s see how can we make a flowchart of our game, which is easily integrated to
Unity as well.

17. Pseudo Code for the
above flowchart
Note: Not the actual code of the game. It is
just for understanding the flow of the game

18. We’ll be waiting to see your
flowchart
See you next week
