Hi,

I'm using :
cId = checkForCollision(dir, step);where step =2f and dir is a direction SimpleVector from a projectile (he moves along this dir)

My problem is :

I've a projectile :  That I want to move except if there's a collision and in this case I want to do something else.
So basicaly I use checkForCollision each time before moving.
if(cId==NO_OJBECT)then I move
else
do something else.

My projectiles are configured like this when I create a project :
       addCollisionListener(this);
setCollisionMode(COLLISION_CHECK_SELF);
setCollisionOptimization(COLLISION_DETECTION_OPTIMIZED);

Now the objects I want to collide with have this settings
addCollisionListener(this);
setCollisionMode(COLLISION_CHECK_OTHERS);
setCollisionOptimization(COLLISION_DETECTION_OPTIMIZED);

The problem is that even I'm seeing that the 2 objects are colliding cID still equal to NO_OBJECT
so no collision detected.


Am I doing something wrong ?

I think I've found something it's probably related to the fact that Player inerith from Camera.
When a player is create it does automaticly call constructor from Camera
perhaps at this moment it does override the jpct world camera.

I'm trying to do this with a composition instead.

Better print to understand :  start direction is  getDirection from camera  and start position getPosition.
Called each time a bee is fire

[First fire -> camera looking scene]

[Second fire -> camera looking away]

05-29 09:32:50.879: INFO/System.out(15615): Live a bee : Bee0 id: 6

[edit]
since I only apply rotation to camera I understand that position never change
but direction should change T_T

Oh strange.

Let me just show what I do:

tiltSensors.addSensorsListener(new SensorEventAdapter() {
       public void onOrientationChanged(OrientationEvent e) {
      // NOT A GOOD IDEA !!!! initial camera position should be kept
      // when initialized and then the necessary angle calculated.
      PLAYER.lookAt(honeyPot);
      PLAYER.rotateCameraY(e.yaw);
      PLAYER.rotateCameraX(-e.roll);
      // PLAYER.rotateCameraZ(e.pitch);
       }
   });

PLAYER inherits from Camera so it's a camera with few more members and function I added ( I know it should be composed instead of inheriting but I've very few time left and I'm doing as fast as I can).

now when I shout a projectile I take the vector direction and position to get the "starting point + direction" of the projectile.

I've just a little function live wich create the projectile
public void live(SimpleVector start, SimpleVector dir) {
this.dir = dir;
alive = true;
System.out.println("Bee : " + getName() + " IA id: " + getID());
System.out.println("Bee dir : " + dir.toString());
System.out.println("Bee start : " + start.toString());
translate(start);
//rotateY(Game.ROTATION_Y_FACE_SCENE_FROM_CAMERA);
show();
enableCollisionListeners();
    }
So nothing big here...
Then to move the projectile I do this

              dir.add(dir);
              translate(dir);

The problem is when I do this.
   
public void onFireBee()
    {
for(Weapon w: bees){
   if(!w.isALive()){
w.live(PLAYER.getPosition(), PLAYER.getDirection());
System.out.println("Live a bee : "+w.getName()+" id: "+w.getID());
break;
   }
}
I just "create" make a projectile alive, on an arraylist of projectiles when a button is pressed.

That's all, but when I do this the projectile still follow the initial camera direction not the current one...

ps: I don't touch camera values or function inside PLAYER, it's a direct call to Camera functions.

I've another problem, I'm using camera.getDirection()

But even if I move the camera with camera.rotateCameraX/Y/Z
getDirection still continue to give me the direction of the backbuffer and not the actual poiting camera direction.

Is there a way to solve this ?

I shot projectiles from the camera position and direction that's why I need this.

[edit] I'm using rotateCamera  not rotate.

(About the spica, I don't have access to it right now I'll try again Monday when I'll have again access to spica)

Another question, is it possible to know world camera position ?

Another question is it really necessary to run strip on models after build ?
I would like to know if there's an improvement, I can't find where to see how much RAM my app is allocating so I can't really test if it's better or not
