Making a particle system track a bone?

[InfinityComplex]

Is it possible to do this?

I tried,

Code: Select all

class Particles{
public:
       Particles( String name,String psys,Bone *attach){
             rSys = ParticleSystemManager::getSingleton().createSystem( name,psys );
             node = gsmgr->getRootSceneNode()->createChildSceneNode();
             node->attachObject( rSys ); 
             bone = attach; 
       };
       Particles( String name,String psys,SceneNode* parent=NULL){
             rSys = ParticleSystemManager::getSingleton().createSystem( name,psys );
             if(parent==NULL){
                 node = gsmgr->getRootSceneNode()->createChildSceneNode();
             }else{
                 node = parent->createChildSceneNode();
             };
             node->attachObject( rSys );        
                         
             
       };
       ~Particles(){
       };
       void update(){
            if(bone!=NULL){
               node->setOrientation( bone->getWorldOrientation() );
               node->setPosition( bone->getWorldPosition() );
            };
       };
       
       void AttachTo( SceneNode *aTo){
           //      aTo->attachObject( node );
       };
       void AttachSub( SceneNode *aSub){
       //      node->attachObject( aSub );
       };
private:
SceneNode *node;
ParticleSystem* rSys;
Bone *bone;
};

Which basically sets the node the particle system is attached to, to the world position of the bone and the orientation to the world orientation of the bone.

The result is although the particle system seems to rotate as the bone does, it doesn't match or appear to be in sync.
Also, the set position has no effect, it stays isolated at 0,0,0 where the bone starts.

The bone in question being joint10 of the robot mesh.

Any ideas?

Is it not possible to attach a scene node to a bone so the particle system it's self is updated by the engine instead of the manual code I'm using?

Try attaching the particle system to the bone itself. That way, when the bone moves, particles move as well.

Code: Select all

Ogre::Entity * mEntityToAttachTo->attachObjectToBone(strUnmanagedBoneName, mEntity);

D'oh, didn't think to look for it in the entity class. Works now.
Thanks.
