today I want to focused on game developing with IPhone.
Best tool for develop IPhone game is Xcode that you should
run it on mac.For windows and visual studio you can use
mono project and develop iPhone application with it but it is
not good as Xcode .
In Xcode you have many template for building application.
For games you should chose opengles template and
start coding.in following post I’ll describe more about it.
what you need for developing IPhone application?comment it.
Windows phone 7 comes with news developer tools
and attract more developer and of course more hacker!
today we have 3000 applications for windows phone 7
and it goings up,of course it is less than iPhone
applications and wp 7have ways to reach iPhone
this week come with new jailbreak tool for windows phone 7 that named ChevronWP7 allow developer and install new wp7 games and tools without going to Microsoft approval process.Of course Microsoft doesn’t like this tool .Now we should wait for new court and wars between Microsoft and hackers
before xna and visual studio setup you should know that your graphic card must be compatible with xna that means you should have graphic card with diret3d that support xna framework Hidef profile. Also for using xna 4 you need have visual studio 2010 .
Now created project.you can use just visual c#.net language for create project .Next you’ll see environment like above.In left sidebar you have files of project and in middle part you’ll see code of game.if you run project a blue window will be appeared.you can changed it easily.Just go Draw function and change this code GraphicsDevice.Clear(Color.CornflowerBlue); to this one GraphicsDevice.Clear(Color.Red); and you’ill see a red windows.For now it is enough 
for developing android application you need download android sdk and eclipse and adt plugin .then create a sample project,when you run your applications it show your result on simulator.
result is something like this
now you want change string .Android application main language is java but coding is different from normal java mobile program;you have main class that open main.xml file in layout folder.This xml file have LinearLayout,and textview nudes.in in textview nude you see this code:android:text="@string/hello" that define some values that contained in values folder .Its names is hello .change string and run it again.just this!

more comes in next postswhen you want use keys you should noticed that have many function
like keyPressed(int keyCode),keyReleased(int keyCode) ,keyRepeated(int keyCode) if you want use all of them should have something for control number of key pressing and releasing and repeating. with this code detect which key is pressed
int gameAction = getGameAction(keyCode);
switch(gameAction){
case UP:
key= "[UP]";
break;
case DOWN:
key= "[DOWN]";
break;
case LEFT:
key= "[LEFT]";
break;
case RIGHT:
key= "[RIGHT]";
break;
case FIRE:
key= "[FIRE]";
break;
case GAME_A:
message = "[LEFT_UP]";
break;
case GAME_B:
message = "[RIGHT_UP]";
break;
case GAME_C:
key= "[LEFT_DOWN]";
break;
case GAME_D:
key= "[RIGHT_DOWN]";
break;
default:
key= "";
break;
you can add all of code in same function.then define value like speed; we assume that in our game when you continue on key press you have more speed so add this code after detect key “speed++”;But after checking speed in real device you see that you object move slower than emulator.it because that device can’t process graphic like computer and emulator.You have to use timer functions and class in your games or using smaller graphic file in next post you see how do that
In game canvas you can detect keys and touch and using graphic function.Canvas have pre defined functions .For using touch in your game you have three function
protected void pointerDragged(int x, int y)
protected void pointerPressed(int x, int y)
protected void pointerReleased(int x, int y)
they are active when you dragged or pressed or released your finger(or pen) on your device.X and Y is place of your finger or pen.If you want same action for all of function you can define another function like this
public void doyouraction(int x,int y)
{
//add your code here
// you can change your function name(doyouraction)
}
in other hand you should have deferent code or functions
{} are keyword for define start and end of your codes.Public means that you can use your function in other class ,if you don’t want use private instead.After coding function use it with this codes
protected void pointerDragged(int x, int y)
{
doyouraction(int x,int y) ;
}
just this,in next post you’ll see infoo about detect keys and code for them
When you build a java mobile game in software(like netbeans IDE or eclipse..)
first thing you‘ll see is a middlet class .Middlet class used for handling start and
initialize and interface of java mobile applications. In netbeans you have sample
screen that can add button or text or image or like that .just you should drag your desired items from right side to screen and then go to source
screen is interface of your project in netbeans
For example you have pre defined string seeing in screen and want changed it when middlet started. Code is like this
public void startMIDlet() {
// write pre-action user code here
switchDisplayable(null, getForm());
stringItem.setText("my name is dawood");
// write post-action user code here
}
startMIDlet is function that using in every middlet .In netbeans for adding interface to screen using a form , should calling when middlet started.For this purpose have this code switchDisplayable(null, getForm());
and then add this for changing text stringItem.setText("my name is dawood");
and run it in emulator
in start for do more thing in java games you should add canvas class that i’ll describe later
Ok first you should know tools that used . There is so many tools you can use for create mobile games.But three of them are most important than others.Everyone have some profit and loose to others and on base of your needs can use one of them.
1.NETBEANS
Netbeans is oracle tool for java programming(windows and mobile and..).Oracle bought java and Netbeans from sun company .Netbeans
have visual library.It means that for create some tools like web tool and windows form you can drag library like button and forms and textbox and..to your program without code.But It can’t use for some mobile 3d games.
2.Eclipse
Eclipse is ibm tool for for java programming.Andriod officially support eclipse(not netbeans because oracle and google problem).Netbeans have also plugin for android but isn’t officially supported.Eclipse ide have also better plugin support from netbeans.
3.microsot visual studio(express have no mobile support)
Best to for windows mobile programming but no java mobile support
now ready for programming!
