 Powerful
 Ubiquitous
 2D games
 Development Cost
 Firmware Dependent
 High fragmentation
 Very complex
 Very powerful
 Close to hardware

Creating a Game Template
Write Once, Run Anywhere

17
Getting Started - Creating a Game Template
 Made to simplify the development
 Made to improve the productivity
 Made to hold many games
Main

Write once
Run anywhere

Creating a Game Template - Example
 KeyManager.isRightKeyDown()
No Template Template
Test Player
Check and Return Boolean
Test
Keypad ‘6’
Compare via Keys Database
Key.getAscii()Key.getCode()
Test
Joystick Right
Building a robust Template
allows you to keep focused
on your Game Development
KeyManager Object

 Player, Handset profiles…
 Key Manager
 Cookie Manager: Saves, Records…
 Game Interactivity: Intro, Menu, Help screen, Navigation, Pause…
 Network Features
 Tools Library: Math, Time, Menu, Algorithms …

Developing the Game
Developing a cool“Casual Game”- SNAKE - in 10 minutes:
3 movieclips:
•Snake’s head
•Snake’s body piece
•Apple
Then just call snakeAlive()
Function on onEnterFrame.
Function snakeAlive() {
if (MyMng.isInPause) { return; }
If (KeyMng.isRight) {
snake.goRight();
} else if (KeyMng.isLeft) {
snake.goLeft();
} …
If (snake.isOnApple) {
MyMng.scoring(1);
snake.addBody();
}
}
Your Template should manages
‘saves’ and ‘records’ for you.
Use MyMng.scoring(x), and
it will be automatically saved.

Developing the Game
10 minutes after …

Developing the Game
… and after graphic design

25
Testing and Optimizing the Game
The « Mobile » Reality

26
 Does not reflect the handset
capabilities
> colors, speed, latency…
 Debugging Tool
Testing
 How your game really runs on
mobile
 Devices do not react the same
 That’s why it is important to test on
all targeted devices
Simulator Devices

27
Optimizing
Significant optimizations from Mobitween’s experience:
 Do not use too much vectors, prefer bitmaps when possible
 Use the right bitmap format JPEG vs. PNG
 Optimize shapes and outlines
 Avoid animating lot of movie clips at the same time
 Avoid complex uses of Math and loops
 Avoid many code in the same frame
