Thanks.

And Yes, it may happens when the bullet or the ships moves  at great speeds, especially when they move one to each other, it may happen that. I should consider doing on that way having a max speed for a bullet considering the ship size/speed and the bullet size/speed!

If the ship moves into a bullet during the ship-move-phase, it doesn't matter, because in the next bullet iteration, the collision will be detected anyway

Yes, I was thinking on that too, but the problem is that it requires 2 movements to detectc the collision and that may result on a no detection on cases in which the bullet speed is too high. For example. (This can always happens but detecting on every movement reduces the posibilities)

Ok, I could add the listener to the ship too, but it wont change anything in that problem becausse I wont be able to know if the ship collided with an own bullet or with another one becausse Iwont be able to recognize the target. Of course that from one collision, one is the source and the another one is the target, but I cant relationate on event with the another one. Or does the Collision event has a unique numer to match??

in my Thread. I first move all the ships, one to one, and then I move the bullets, ont to one.

But lets imagine this:

case1: Listener on the ship
Ship 1: moves and collides with Bullet 1 (I know there were a collision so I can remove the bullet from the world, and reduce the life of that ship, but as I dont know the target I cant know the kind of bullet to know: how much life to reduce and who shoted??? and I cannot do the check for not colliding with its owner) Source: Ship1

or this another one case:

case2: Listener on the bullet
Bullet 1 moves and collides with Ship 1 (I know there were a collision so I can remove the bullet from the world and I know how much life to reduce from the target if it was a ship, but as I dont know the target I cant know the ship so I cant reduce the life to anybody and I cannot do the check for not colliding with its owner) Source: Bullet1

case3: Listener on Both, all ships and all bullet
Bullet1 moves and collide ship1 (Cant know which ship was afected becausse I cant know the target) Source Bullet 1.

I have a BulletListener class that is the collisionListener for all the Bullets, Maybe I would have to use a new CollisionCHecking class for each ship on both CLIENT and SEVER sides.  On that way I can solve the problem on case 3. I guess the only way to do it is to have exclusive Collision Checking instances for each bullet and ship in the world.
That class will hava a reference to the object, so when a collision happens I can know the objects involved. (I dont care about who was source or target, I just care about the objects involved).

Wouldnt this increase the resources needed or maybe generate a bit of lag, having a new class for each object3d?

Well I decided not to take the images nor the maps  from a database but to save them on a web hosted visible path, and to ensure the privacy I will modify on somehow the bytes of them to make it unreadable until its loaded on the applet, and then I will fix it again.

Any way this 3d part is delayed until all the documentation and the web development is done. It wont be a big thing, so dont expect too much of it when released becausse I am very dissapointed about the project but must be finished.

enableGLCanvasRenderer ... look at the GL word. it means it uses OPEN GL, that means hardware renderer. if you want to hace software render on a canvas just put the render stuff on the paint methos over an awt canvas. There are some examples over there. On the download section, there is a project called Maze, it was my first jpct applet, it may help you.

Well, yes now the listener is firing the events. Thanks. I a running into a problem now. A problem os my design. Is about precision. Actually, for each iteration the client sends the events to the server and the server moves everything, so I have a defined speed for turning and moving, but in a FPS the most important thing is the presision of the movements, for example:

         A.                         B.                           C.
         |---------5f--------|----------5f---------|
         |-----------------distance----------------|


Supose my cam is lokking at A and for each event I turn certaing degree to make the camera look at C.

Then I will never be able to aim B. point.  making it turn a lower angle or move a smaller distance will make the game too slow. Any idea about this issue?

I was thinking about moving the cam a smaller angle/distance. But separating the moving thread from the networking and from the rendering threads. The problem is that letting a free independent movement
on the client will lead to cheating. Thats why evertything is controled on the server.

mmmmmmm Yes, I set The collision mode before constructing a new Bullet from the model. Well, I guess I should use a clone method the have an exact copy? I will set the CollisionMode after creating the bullet to see if it helps, I will post the results by tomorrow! Thanks a lot, and please replace the old version of my project beucasse that was a version in which nothing works! Hopefully I will finish the first realease of the game sooner. And of course after that I will have to spend some time modelling some good maps, spacecrafts, bullets, misiles, etc!

Its okay. The search engine of the forums is not working well, and asking is the only way to get knowledgment. Feel free to ask whatever you need.
