Hi All,

In normal 3D object in World space, following collision detection code worked.

sphere.setCollisionMode(Object3D.COLLISION_CHECK_OTHERS);
            sphere.addCollisionListener(new CollisionListener() {
               
               @Override
               public boolean requiresPolygonIDs() {
                  // TODO Auto-generated method stub
                  return false;
               }
               
               @Override
               public void collision(CollisionEvent arg0) {
                  Log.i("HelloWorldJPCT", "Sphere collision");
                  
               }
            });

When I tried the collision detection in Bones sample code , I never got any log message, Following is the code

ninjas.get(0).get(0).setCollisionMode(Object3D.COLLISION_CHECK_SELF);
      ninjas.get(0).get(0).addCollisionListener(new CollisionListener() {
         
         @Override
         public boolean requiresPolygonIDs() {
            // TODO Auto-generated method stub
            return false;
         }
         
         @Override
         public void collision(CollisionEvent ce) {
            // TODO Auto-generated method stub
            Log.i("app", "On collision");
            
         }
      });

Please let me know if I am missing something.

Regards,
Subha

Bones does not do/change anything aboout collision detection. To be sure, I did a quick test by modifying collsion detection sample in wiki. added the lines below. collision detection worked and collision events are generated.

I'm not sure what's wrong with your sample. maybe it's the scaling of objects?




--- Code: --- cube = BonesIO.loadGroup(new FileInputStream("ninja.group.bones")).get(0);
cube.scale(1f/10);
cube.translate(-50, -300, -50);

cube.addCollisionListener(new CollisionListener() {
@Override
public boolean requiresPolygonIDs() {
return false;
}

@Override
public void collision(CollisionEvent ce) {
System.out.println("collision");
}
});

--- End code ---

Hi Raft,

Sorry I forgot to mention this before, I am checking collision with bones in Android (JPCT-AE). I will check again what you have mentioned. Does Android engine can have an impact in Collision detection with bones  ::)?

raft:
no, I don't think so

Hi Raft,

I tried again, but no luck. I am attaching the source code.
Previously in JPCT-AE forum, when the collision didn't work, One suggestion was given to make the screen as full screen. I did the same in this project also.

<activity
            android:label="@string/app_name"
            android:name=".BlendprojectActivity"
            android:theme="@android:style/Theme.NoTitleBar.Fullscreen">
            <intent-filter >
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

Do I need to post the question in JPCT-AE forum also ? I need the collision as I am trying to detect if the user has touched any specific area in animation.  :(

Thanks in Advance.

Regards,
Subha
