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

step2:rotation object in game

you can rotate your object in 2 way.Which way you select is in base of your games and

algorithms and graphics of your programs.In first way you can set origin in game by

setOrigin function or like it.prerotate and postrotate function invoke this origin on

base of your origin and object default origin and make new origin.( see here for technical

information) This way is used when you want change your rotation origin on base of your game

algorithm and you havn't any fixed origin for your objects .But you can set your orotation origin in3d model maker software's and export it m3g.it is better using mascot capsule because some

exporter maybe can't export your origin and will be using default origin. For this porpose in 3ds

max 2008 for rotate leg on base of its upside

first in command panel we select hierarchy(third box from left)

then select pivot button and click on affect pivot only and then you can see small pivots.it is your

rotate or move or scaling origin you can move it to your desired picture and then click on align to

object only button in below now you can rotate your objects in new origin in model and game.

you should export this model to m3g with tool that i said before or another good tool and use it in game

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 .

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);
