So, I've modified the loadFerito() method as follow:
where animArray[0] contains the first ferito's pose and animArray[1] contains the second that is, at this moment, the last. Running the applet nothing happens... Do you see any problem in my code?
Bye
Code: [Select]
public void loadFerito(String name, float x, float y, float z){
Object3D animateMe=null;
texMan=TextureManager.getInstance();
texMan.addTexture(name+".jpg",new Texture(getDocumentBase(),"textures/feriti/"+name+".jpg"));
Object3D[] animArray=Loader.load3DS(getDocumentBase(),"3ds/"+name+"_anim.3ds", 20f);
animateMe=animArray[0];
animateMe.setCenter(SimpleVector.ORIGIN);
animateMe.translate (x, y+55, z);
animateMe.rotateX((float)-Math.PI/2);
animateMe.rotateMesh();
animateMe.setRotationMatrix(new Matrix());
animateMe.createTriangleStrips(2);
animateMe.setCollisionMode(Object3D.COLLISION_CHECK_OTHERS);
animateMe.setCollisionOptimization(Object3D.COLLISION_DETECTION_OPTIMIZED);
//animateMe.build();
Animation anim=new Animation(animArray.length);
anim.createSubSequence("standing-up");
for (int i=0; i<animArray.length; i++) {
animArray[i].build();
anim.addKeyFrame(animArray[i].getMesh().cloneMesh(true));
}
animateMe.setAnimationSequence(anim);
animateMe.animate(0);
theWorld.addObject(animateMe);
}

Hi Egen,
I've solved my problem... :mrgreen: The problem was in the order in which things are made; in fact, moving the calling of readConfigFile() (and conseguently the calling of loadFerito) after the constructor of the world, everything works fine.
Bye and thanks

Ok, I'll try as soon as possible (after solving my previous problem that, as you can see in the forum is still here....).
Yes, ferito is a wounded; I've to create a simulator for an University Medical context.... I've to simulate situation like road accident, and so on...

theWorld is definited global:
I've followed your steps: I've moved ferito's definition and "adding to the world" into loadFerito() as follow:
Now I have not a null expection....but none "ferito" is displayed even if correctly loaded.... I'm becoming crazy :shock:
Code: [Select]
public class ThreeDSimApplet extends Applet implements Runnable, KeyListener, MouseListener {

Another task: Animation. I have to start an object animation when something happens. First consideration, even if I problably I already know the answer: is it possible to import a keyframed animation created in Maya/3D Studio into jPCT? If, as I suppose, the answer is no let try to see if I have understood that way to create animations in jPCT: I load a 3ds file in which I’ve created variuos poses of my obj to animate (every pose corresponds to a keyframe); I load this file as usual, i.e.:
every element of the array animArray is one of my poses (I guess), so after defining and instanciating an animation:
where n is the number of keyframes (poses) that I want to use. What is pretty cloudy to me is the way to use mesh (that I’ve to pass to the method addKeyFrame), in your documentation you say:
“Mesh can't be instantiated directly”, so in which way can I use them? After adding all my keyframes to the animation, it simply starts when I start the applet? In which you use the interpolation attributes?
Thanks a thousand of times

Hi Egon,
as you know I’m using a config file where an operator can decide how many objs to load and where to place them; for instance:
my init() is:
where readConfigFile() is method that scans the config file; when it find out a line having the word “ferito”, it passes to a method loadFerito that name (completed with 1 or 2) and his coordinate:
Even if the two 3ds object are correctly loaded:
It’s displayed just the one in the last line of the config file. I guess this behavior is dued by the fact that

my init() is:
Code: [Select]
public void init() {

if ( param != null){
FileToRead = new String(param);
}
// Now read the file.

Code: [Select]
theWorld.addObject(ferito) is outside loadFerito() and so it passes just the last value of ferito to init(). So I’ve tried to move Code: [Select]
theWorld.addObject(ferito) in the last line of the loadFerito method (and even Code: [Select]
theWorld=new World() to avoid a null exception) to try to add an obj to the world for every ferito’s occurance, but nothing changes... Any suggestion.....Bye and thanks

It’s a problem related to the position of the obj in Maya’s world coordinates: placing the obj in the center on the Maya’s coordinates (0,0,0), it behaves correctly in jPCT’s world.

Support / Camera position object3D position mismatching
« on: June 14, 2004, 05:51:01 pm »
Hi Egon,
I’ve to implement the following capability: I need to place some objects in the world using custom coordinate. So, for decide where place objects I’ve to move myself in the world (by the camera) and, where I decide to place an object, pressing the right click, my applet has to pass the camera’s coordinate to a html page. I’ve created this feature in this way:
then I’ve created a function that creates and places the object using the camera’s coordinates:
My problem is that the object in placed in a different position compared to the camera position where I’ve taken the camera’s coordinates. I guess the resulting camera’s coordinates don’t match the object coordinates method. Exist a way to make a matching?
Bye and thanks

Support / A texture error…
« on: June 11, 2004, 04:40:48 pm »
Hi Egon,
another question/problem….. I’m loading textures in a generic way as follow:
in init() method. In my previous version I’ve loaded some objs separately from my world in init() method too, as follow:
Now, I’m using a config file where I can decide to load or not the above obj, so I’ve decide to move the above code in another method, defined by myself named loadFerito(). The problem is that when I perform this, the Sun Java Console says:
where ferito1.jpg is the texture associated with ferito1.3ds and the obj in the applet is obviously white.
If I move back the loading/defition obj code into the init() method everything works fine. Any explanation ? Bye and thanks

Support / Loading texture problem while using certificate

No, looking in Java console no error appears, texture are correctly loaded and added to the texture manager…. And no, the applet isn’t placed in a jar file, is a “stand-alone” class file. I’m not pretty sure to understand what do you mean when you say: “where getDocumentBase() points to in both situations.”
