Introduction to iphone programming

Xcode is  best tool for Iphone and Ipad and Mac programming.You can used so
many interfaces  easily in programming and connect them to source as you
want also with simulator for test your apps.see here for more info.In this picture
you see xcode 3.2.3 ide with iphone sdk 4.0


Every project in Xcode at last have one windows(or view) .In windows we can
add some library like button,label,slide and…For this purpose we should
expand resource folder in left sidebar and open MainWindow.xib or
MainView.xib .Interface builder tool opened and show a blank window.It is
same windows that you see in iphone app. next drag your library from right
side to your windows . If you can’t see library should select tool menu and
then library.

Now build and run your apps .In next post I'll describe opengles tempelete that
is best choose for create 3d games for Iphone .and show how using interface
builders and codes in Xcode.

blender and python and game

blenderis a free 3d open source code.in blender you can run a python code and access to object and rotate and scaled and transform
them .you can first make figure in poser and then import it on blender or 3ds max.for import any poser figure it is better to select unimesh demo in python script box and make a sample demo from figure and then import it to 3ds max or blender.then you can create a code like this

# Windows version 
import Blender
import sys

obj=Blender.Object.Get()
print str(obj)
sys.stdout.flush()

and run it on blender.you can custumize code with loop and others and make a game with it

python and animation

python is great scripting language for animation specially use in blender and poser.
with a python script you can control tools of this software and moving of object in this.when you want to make game with java you can run a script sample in blender or poser for test of your game in real 3d scene and then make a java code for it.you can download python ide from here
this is a picture of python shell ide

and this is a part of code for rendering frame of 1 until 10 and save their images
PoserFile.append("E:\\dawood\\movie\\movie1.pz3")
TargetDirectory.append("E:\\dawood\\movie\\run\\")
FramePrefix.append("Run")
StartFrame.append(0)
EndFrame.append(10)
this codes help you also making animation easier and faster and control animation scenes.

animation and sound in 3d games

for this purpose you should use synchronized function for synchronized animation and sound with

your events occurred when key pressing.for Synchronize any functions you should use synchronized word before you functions this function is used for play mp3 sound
public synchronized void playmusic(String file)
{
if(sound==0)
try
{
Player p = Manager.createPlayer(file);
p.setLoopCount(5);
p.start();
}
catch(IOException e)
{
System.out.println("Error in io : " + e.toString());
}
catch(MediaException e)
{
System.out.println("Error in media : " + e.toString());
}
}
you should add this function in function that you want played syncronized .
public void keypress()
{
playmusic(file);
}
for animation you can make any arbitary function like this
syncronized void animation()
{
x++;
group.setTranslation(x,y,z);
}
this function force to moving a group in x axis without stop!
this was a sample way for animation and sound in java 3d game.

sample tips in making mobile game:graphics 1

tips1:
When you making a mobile games you should know that you can't make full city or even building

and textured them.Because it forced to have bigger 3d models and some mobile device's(or all of

them!).In this case you can textured your desired city or building or...in sample plane or cube

and move camera toward them. in game it seems that you moved in real city or building but you

moved to image .Then you can add your game sample building and humans and creatures to other

side of pictures.like below


this is my video

steps in making real 3d game

1.moving
moving of objects in 3d game is an important step in games and you should have good control in moving light and cameras .Camera position is on base of your game strategy and your game algorithm.for example in this test game(i'm still beginner) I set camera position with this code.
cam.postRotate(45, 0, 1,1); cam.setTranslation(xpos+40, ypos-50, zpos+60);
and you'll see camera in front of girl and above of her head when she moving near house.
in this video you will see how camera move(xpos,ypos,zpos is girl position in 3d place)


another method for moving is using transformation and transform matrix . a transform matrix is a 4 X 4 matrix and in java code you write it as float array with this code
float[] matrix={1,0,0,sx
,0,1,0,sy
,0,0,1,sz};



Transform m=new Transform();
m.set(matrix);
now for moving camera and human in x axis(1 unit) set sx=1 .If you have mesh with name human and camera you need only to this code for moving them.
camera.setTransform(m);
human.setTransform(m);
With setting sy and sz you can moving in y and z axis

.Matrix transform is very good for rotation and scale also. In next post i show how you can moving human with rotate hand and leg and body.This game also need a sample algorithm for moving girl .

You can download game for playing from this link

(sorry for some problem in exit and speed it was my first game)

Advanced programming II: images and text

Advanced programming II: images and text

Now we want focusing on making better game. For better game we need some text for showing score and some images for maps and other thing and at last a better graphics for getting your game more reality .

In design of 3d models you need getting texture from building and objects that you want to use in game. Some texture maybe force to distortion your model and even maybe you can’t see anything. And of course more high graphics texture and models may not be seen well in some old phone. For example when you download this game for p990 sonny erricson you see a picture like it

But when you want to download it for k750 from same company (sonny ericsson) you will see some graphics problem and maybe even you can’t see some models in older phones.

Add text and images and some functions

You can add text and images to your games with Graphics class and bind Graphics3D to it .You should add text and images to graphics after bind it to Graphics3D . it is an example code

g3d.bindTarget(graphics,true,Graphics3D.ANTIALIAS|

Graphics3D.TRUE_COLOR);

g3d.render(_world);

g3d.releaseTarget();

graphics.setColor(0x990000);

graphics.setFont(Font.getFont(Font.FACE_SYSTEM, Font.STYLE_PLAIN, Font.SIZE_LARGE));

graphics.drawString("corner", 90, 150,

Graphics.TOP | Graphics.RIGHT);

In first code we bind target graphics(from Graphics class) to g3d(from Graphics3D) and in second line we render my world class . After release your g3d object you can change your graphics object and add image or add text .For add text I use three line for set color and font and text.

Add images is like that and only you need add function drawimage and image object to your code.This image can be maps or character picture or other thing.You can add some function also to your program for controlling move of cameras or objects in your game.I add a sample code for this porpose.

if(y>-20)

Y=-20;

With this code camera will be stopped if it reached to left wall.In 3ds max wall y position was 20 and

Camera will be moved to Y with this code

camera.setTranslation(X, Y, Z);

Advanced programming I: lights and cameras

1.your 3d model

In every game you should select your lights and cameras carefully and move them on base of your objects moves specially in 3d games.

In this 3d model you see three light( free spot) and one camera and panel and ball(sphere).this is a sample game for moving a ball in panel.For using it you should export in m3g After do that maybe you see a view such this in a m3g player

As you see you may lost some graphics on base of your m3g exporter and your 3d software now you are ready for moving your lights and cameras.

2.moving your lights and cameras

Java have two class for moving light and cameras in m3g files with name Light and Camera.

For moving light and cameras you can use this codes

Light l=(Light)(Myworld.find(lighted);//getting your desired light

l. setTranslation(x,yz);//move it to x,y,z location

Camera m;m=(Camera)(Myworld.find(cameraid);//get your desired camera from your world

m.setTranslation(x,y,z);// move it to x,y ,z location

now you can run your game in netbeans emulator (see picture)but you should now that your game maybe presented in mobiles differently on base of their graphics.

You can send your comments about this post .I'll be glad for them.

Download and develop your 3d java game mobile

For starting in programming with netbeans first I upload a sample java mobile game project that you can download it and run it or change it and even make a new game.

3d model making

1-for starting programming first you should have 3d model maker .this software should can export models to m3g.I using 3ds max 2008 but you can also use any 3d software like blender and a m3g exporter with it.Blender and m3g exporter are free.Maya is another good software for it but is not free.Every box and sphere you create in this software ,have an id in m3g that give you access to them and You can rotate and move this object .Graphics of this model maybe have some problem in

Some phones on base of their graphics.

Netbeans project information

2. After make your 3d model and export it now you are ready for programming .you should export your 3d model to subfolder "src\res" from your project folder .

My game engine is panel1 class and game canvas is "Canvas" and middle is hellomiddlet. 3ds model is in res folder (game1.max)with m3g file and you can change this model in way you want.your project name in netbeans is your project folder(unzip file after download) and you jar file is in dist folder.You can run it from mobile .In next post I'll explain my project functions and cods and models.

About functions and code

Panel1 class have two functions setmeshpositions and movemesh.setmeshpositions (15,35,35,35) means that your object with id 15 is positioned in 3 dimension space in xyz coordinate(x=35,y=35,z=35) and movemesh(15,"up",5) moving your object with id 15 to up direction in 5 unit.For example in this code

int state = getKeyStates();

if( ( state & DOWN_PRESSED ) != 0 ){

panel.movemesh(15, "up", 5);

state value is 1 when your using a key(in otherwise is 0) or no and DOWN_PRESS value say that you pressed down or

no and if two of them are true mesh move up 5 unit in up direction.you can change this code with replace up with down or like that.in next post I'll write some more about this codes and functions.
