Hi, I have some questions.  Whats the best way to sync two objects together over a network.  Right now I send transformation and rotation matrix clones every 50 ms over an ObjectOutputStream or something like that and also have the keypresses sending so that it can continue to translate the objects in between those 50ms. its pretty good but doesn't seem to be perfect when i have 2 clients open it has a slight delay before one can see the movement.  I was just wondering if theres a better way or perhaps this delay is due to my logic in constructing a pojo to send across the stream and then checking all the objects on the client side to find the one that is referenced by the pojo, etc.

Also how can I make something collidable with everything? I only see that theres a setting that check collision self and check collision other.  Is there no way to make it collidable with everything for example if I have 3 objects that can collide with each other?

Also if I use a .obj how do I get material to work?  If I use a .3ds exported from 3ds max with texture coords and then import the jpegs itto jpct, it will automatically put them on my model.  But I tried with a .obj exported from 3ds max and i set the .mtl file also and then i noticed that jpct imported all the correct jpegs after it read the .mtl file but it didnt seem to show up in the actual world.

Also why does it seem like sometimes parts of my 3ds file will be in the wrong position when i load it into jpct instead of the position it was in when i open it in 3ds max.  If i use a .obj file though this position problem doesn't happen but i'm not sure how to use textures.  So far I believe this 3ds problem only happened if I cloned a copy of an object, but im not sure.

Thanks,

Hey I have another problem now.  Can you tell me why this happens?

i have a class that looks like this:

public class Pellet extends Object3D implements Runnable{
    Shoot shoot;
    public Pellet(SimpleVector direction){
        super(Primitives.getSphere(2f));          
        shoot = new Shoot(this, direction);
    }
    
   public void run() {
       shoot.start();
    }
    
    private class Shoot extends Thread{
        SimpleVector direction;
        Pellet pellet;
        float speed = 10;//speed of bullet
        int time = 15; //time bullet exists
        Shoot(Pellet pellet, SimpleVector direction){
            this.direction = direction;
            this.pellet = pellet;
        }
        @Override
        public void run(){
            int count = time;
            direction.scalarMul(speed);
         while(count > 0){  
            try {                
                sleep(100);                
                pellet.translate(direction);
                count--;
            } catch (InterruptedException ex) {
                Logger.getLogger(Pellet.class.getName()).log(Level.SEVERE, null, ex);
            }
            
        }
           Main.world.removeObject(pellet);
        }
    }  
}

and implement it like this:

case (Keyboard.KEY_LCONTROL) :{
                if(event == KeyState.PRESSED){
                combat.Pellet pellet = new combat.Pellet(model.getXAxis());
                pellet.setOrigin(model.getTransformedCenter());                
                world.addObject(pellet);
                pellet.build();
                pellet.run();
                }
            }

It basically creates a sphere where the player is standing and it shoots forward and then dissapears after awhile.

at first it seems to work fine but if you spam it really fast at some point it causes a null pointer exception at com.threed.jpct.World.renderScene(Unknown Source).

However, this null pointer exception does not happen if I remove the Main.world.removeObject(pellet) from the Pellet class, in other words I don't get the error if I keep the sphere on the world.  Is this because I'm doing these changes to this object outside of the main Thread again? How can I make something keep moving outside of the main thread?

Here is a link to the program again: http://www.sendspace.com/file/77n790

Hello.  In this program I am making when I try to move my character it looks like it flickers/jerks now and then.  What can cause this?
I noticed it doesn't seem to do it if I don't move the camera at all.

Here is my program.  You can run it with runGame.bat and move with the arrow keys.

Where is the advanceAnimation method?  I've been using the animate(float index, int seq)  method for my animations, which u can speed up or slow down depending on the value of the float index.

thnx i fixed it, i had a typo in my code.
i had:
                        matrix.set(2, 0, nine);
                        matrix.set(2, 3, ten);
                        matrix.set(2, 3, eleven);
                        matrix.set(2, 3, twelve);
                       
instead of
                        matrix.set(2, 0, nine);
                        matrix.set(2, 1, ten);
                        matrix.set(2, 2, eleven);
                        matrix.set(2, 3, twelve);
