Some of our games

Let me know my audience

Some 2D Game examples

How to make them ?

Building blocks of a game

● Art & UI - Artists

● Code - Programmer

● Sound & Music - Sound Artists

● Story & Game Play - Creative Director

● Play testing – Testers

● Marketing team, Publisher, Analytics team, ...

Platforms

● PC (Mac , Linux)

● Web

● PS4

● Xbox

● Android

● iPhone, iPad

● Wii, DS, PSP

● Microconsoles, Smart TVs

Different tracks for a game programmer

● C++ - Ultimate, Hard, Free, Puli

● Java - Medium, Moderate, Android, Free

● C# - Great, Modern, XNA, Unity, Moderate, Microsoft ?

● Javascript - Web, Unity, Easy, Free, Fragmented

● Starling uses Actionscript which is Java + javascript

A Game Engine

We use game frameworks to build our game engine

Alternate 2D Game frameworks

● Web - Phaser, CreateJS

● Android - LibGDX (crossplatform), AndEngine

● IOS - Cocos2DX (crossplatform), Sparrow, SpriteKit

Under the hood

● DirectX

● OpenGL / OpenGL ES

For the Non – Programmer ???

● Web – Construct 2

● Crossplatform - Gamemaker

The slide many of you may hate...

What else does a game developer need

● Programming skill

● Creative imagination

● Patience

● Should be a gamer

● Logic & analytical skill. Find hacks & shortcuts.

● Above all strong MATH skills - trigonometry, matrices, physics equations, progressions etc

Hero of the day – Starling Framework

● Created by Daniel Sperl of Gamua

● Actionscript 3 language

● Optimised for touch based devices

Flash & Actionscript

Flash is now only used for

● Games

● Video

Why Starling ?

● Crossplatform

● High Performance

● Optimised for touch

● Easy to learn, very same as AS3 default classes

● Field tested & port of Sparrow

● Great community

● Supported by Adobe

● Open source !

OOP refresher

● AS3 is same as Java

A Class

● Independent blue prints of functionality. Eg, Ball

● Methods (functions). Eg, bounce()

● Properties (variables). Eg, weight

var myBall:Ball=new Ball();

trace(myBall.weight);

myBall.bounce();

OOP refresher

Inheritance

● Class can extend another class's functionality

● Uses 'extends' keyword for the same

eg, Tiger extends Cat which already extends Animal

public class Cat extends Animal {

...

}

Development setup

We will need the following for Starling development

● Flash Builder / Flashdevelop / FDT

● Flex SDK, Compiler

● AIR SDK, for crossplatform deployment

● Flash Player standalone program for testing

● Starling framework classes

Starling Graphics

Simple Starling code

Break !

Next we will start some exercises.

Let us check the development setup first.

Exercise 1

Add an image to stage!

Exercise 2

a. Move the image!b. Set image at click position!

c. Frame based v/s Time based

Exercise 3

Texture Atlas!Add an animated MovieClip to stage!

Start / Stop animation on click!

Exercise 4

Bouncing Ball!

Exercise 5

Trigonometry!Rotating arrow!

Exercise 6

Move the arrow with arrows!

Exercise 7

Trigonometry!Rotate & move arrow with arrows!

Let us create a game!
