Our scenerio

Already have the game in flash AS1/2 We will build for Flash lite 1.1 Nokia S60 – 176 x 208

Case with Flash Lite 2.X We can directly

port our code Only Graphics

optimizations needed

Less number of devices

Require higher version of flash IDE

Tools Required

Flash – mx2004, v8, cs3 Adobe Device Central CS3 Flash Lite 1.1 CDK Flash Lite Device

Graphics Optimizations

Reduce the color palette Reduce the size – 176 x 208 Optimize graphics in flash Remove gradients used Remove transparency used Balance between vector and raster Use PNG raster graphics

Gradients

Optimizing code

Use small variable names Reuse variables Reduce nested loops Flash lite 1.1 is optimized

Design changes

Static 5 levels Pre animated graphics Left/Right arrow controls with enter

key Extensive use of movie clips and an

invisible button

The frames 6 frames labeled logo, menu, help, game, over and win

The game frame Dynamic text box with variable name ‘level’ Mathai animation movie clip mathai Hand movie clips hL and hR A go movieclip for starting The invisible button

Game frame code

lSTime = dT=lLTime=o;level = 1;mF = 20;sF = 10;dR = "";dN = "n";interval = 10000;tellTarget ("go") {

gotoAndStop(1);}tellTarget ("mathai") {

gotoAndStop(1);}tellTarget ("mathai/clip") {

gotoAndStop(10);}//stop();

Mathai Clip frame code

Button codeon (keyPress "<Enter>") {

if (/:dN eq "n") {/:dN = "y";tellTarget ("go") {

gotoAndStop(2);}if (random(2) == 0 && /:dR ne "l") {

tellTarget ("mathai/clip") {gotoAndPlay(_totalframes-_currentframe);/:dR = "l";

}} else {

if (/:dR ne "r") {/:dR = "r";

}}tellTarget ("mathai/clip") {

play();}///:lSTime = getTimer();//

}}

on (keyPress "<Left>") {if (/:dN eq "y") {

tellTarget ("hL") {gotoAndPlay(2);

}if (/:dR eq "r") {

fscommand2("StartVibrate", 1000, 0, 0);//change/:dR = "l";tellTarget ("mathai/clip") {

gotoAndPlay(_totalframes-_currentframe);}

} else {tellTarget ("mathai/clip") {

gotoAndPlay(_currentframe+1);}

}}

}
