Hi Egon,

I’ve to improve my applet defining a config file where someone can decide what world or another object to load without handling java’s code… I’ve created a config file and I’ve added this code to my applet:

    String line;
    String worldValue;
    String tempFile;
    char checkStart;
    File f = null;
    BufferedReader br = null;
   
   
    public void init() {

   
       tempFile="ThreeDSim.cfg";
       f = new File(tempFile);
       
       try{
       
           br = new BufferedReader(new FileReader(f));
           
       }catch(FileNotFoundException fnfe){
        System.out.println("File not found...");        
        fnfe.printStackTrace();
       
        }
       
       try {
           while ((line = br.readLine()) != null) {

         if (line.length()>0) {
           checkStart = line.charAt(0);
   
                  if (checkStart != '*') {
                 
             if (line.startsWith("world")) {
               worldValue=line.substring(6);
                   }
                   
               }
     
           }

    }
   
       } catch (IOException e) {
    e.printStackTrace();
         }

.
.
.


Obviously, when I open my html page the applet doesn’t load because I’m trying to access a file in an applet context. So, I’ve defined a certificate to let the applet to access the file…. using the certificate I can now access the file and reading informations without problems…. But, the problem now is that no texture is visible in my applet (as you know, I’m loading texture one by one in this way:texMan.addTexture("car1.jpg",new Texture(getDocumentBase(),"textures/car1.jpg"));). If is remove the certificate, textures become visible.... but I can’t access the file…. There’s an explanation for this behaviour?

Bye and thanks

Ok, it works, thanks a lot  

Here the results:

theWorld.getObject(120)

returns: com.threed.jpct.Object3D@787c16
theWorld.getObject(120).getName()

returns: object122
I’ve loaded four separate 3ds objs: the first, the second and the third are the selecable objs the fourth is the rest of my world (it can be compared to your level in fps and it’s loaded exactly as is loaded your level). Objcect122 is the rest of my world. Whose is strange is that it behaves as jPCT consider it as a selectable obj, but I have not defined it as selectable.

Bye

Hi, I’m here again to waste your time… but I’ve another question. I’ve implemented the selection objects function, as I’ve wrote in some previous thread, and I’ve place, as you said,  the following code:


SimpleVector ray=Interact2D.reproject2D3D(camera, buffer, mouseX, mouseY);
                     int[] res=Interact2D.pickPolygon(theWorld.getVisibilityList(), ray);

                     if (res!=null) {
                         Object3D pickedObjs=theWorld.getObject(Interact2D.getObjectID(res));
                     }
                     
                     feritoID = Interact2D.getObjectID(res);
                     
                     System.out.println("ID: "+feritoID);


after:


 theWorld.renderScene(buffer);


When I run my applet and look in Java Console, I see that it repeats many times the string ID: 120 when I click in the applet on a non-selectable objs (I guess this code is a default code for non-selectable objs) or the string ID: with the selectable obj code. Why it repeats many times this string instead that just one time?
Second question: I need that this string appears on the java console just when I make a click on a obj; I’ve experimented that if I place the mouse’s arrow on the applet window and I use the keyboard keys to move in my scene, when the arrow passes on a selectable obj (without pressing a mouse’s button) appears the string ID: in the java console. Is it possible to prevent this behaviour making string appears just when I press a mouse button?

Bye and thanks a lot
 

I’ve tried both solutions: I’ve added  this.enableEvents(AWTEvent.MOUSE_EVENT_MASK); in init method, and I’ve tried the other solution:

I’ve implemented the MouseListener interface:

public class ThreeDSimApplet extends Applet implements Runnable, MouseListener

and I’ve added the required methods:

public void mouseClicked(MouseEvent event) {
   if (event.getButton()==MouseEvent.BUTTON1) {
        mouseX=event.getX();
             mouseY=event.getY();
         
             System.out.println(mouseX+" ," + mouseY);
   }
 }
 
 public void mousePressed(MouseEvent event) {
 }
 
 public void mouseReleased(MouseEvent event) {
 }
 
 public void mouseEntered(MouseEvent event) {
 }

 public void mouseExited(MouseEvent event) {
 }    

in both solution the mouse click now works but…… the keyboard events are disabled…… Is it possible to catch both events?

Hi,

I’m experimenting on using mouse in my jPCT applet following, as trace, your way to map keys in your Bounce applet example; so I’ve initialized a variable:

private boolean click=false;

I’ve definited the following method:

public boolean mouseClick(Event e, int key) {
        ProcessKey(key,true);
        return (true);
 }

in ProcessKey I’ve added the following “case”:

case (MouseEvent.MOUSE_CLICKED):     {wire=event; break;}


where ‘wire’ is the the wireframe mode, here just as example. At last, I’ve added the following ‘if’ in the timer():

if (wire) {
                         wireframe=!wireframe;
                }

but, running the applet, nothing happens (using the 1 key, for example, the wireframe mode works, so the problem is just on the mouse event).
I’ve to add a mouse listener….. or something else?

Bye and thanks
 

Thank you very much for your help.... I'd have two another little questions; If I decide to use only sw renderer I'll have not, in theory, any compatibility problem?

I've a problem mapping keys to event.... In fps example, using the following code:

case (KeyEvent.VK_X): { // change renderer  (x)
            if (event) {
               switchMode=35;
            }
         break;
}

you've mapped the x small key to the "event" changing renderer; I've use a similar code to use the q small key to rotate the camera in my applet, but, running the applet, it only works if use the capital q (Q) and I don't understand why......

Bye and thanks again

Hi all,

I'm using jPCT to create an University 3d simulation for medical porpouse; I've created a world using Maya and I've converted the Maya's file into a 3DS file using FBX Converter.
When I load the 3DS file using an stand-alone application, such as FPS, the file is loaded without any problem; Problems occur when I try to load the 3DS scene in a applet, such as Bounce; in fact the Sun Java Console shows the following message:

[ Thu Apr 29 11:20:24 CEST 2004 ] - ERROR: Couldn't read file 3ds\prova.3ds
[ Thu Apr 29 11:20:24 CEST 2004 ] - ERROR: Not a valid 3DS file!
Created 0 triangle-strips for object2 in 1 pass(es)
[ Thu Apr 29 11:20:24 CEST 2004 ] - ERROR: Couldn't build() object! Check if the object is assigned to a world and if the TextureManager has all required textures loaded.

Do you have any explaination about this behaviour? Is it possible that 3DS files don't fit in a web application? If it's so, what other file format should I try? Thanks for any help
