Code Response(s) on features & Request(s)
Concerning the duplicate object request:
sio2_object.cc
sio2_object.h
And a quick example on how to use it inside the templateRender function (or your own rendering loop):
sio2_object.cc
- Code:

Great, thanks alot! I'll try this as soon as possible.

Re: Code Response(s) on features & Request(s)
Note that there's a #endif missing in the header you posted. Besides that, it seems to be working great, thank you!
Best,

Re: Code Response(s) on features & Request(s)
Hi,
does someone test the above sio2ObjectDuplicate method with 1.3.1.
I used the following code with the tutorial_6_1.
Afterwords I moved the new object to an other position with the following code:
But the new object does not appear in the 3D world.
Does anyone have an idea?
Thanks
Ludi
does someone test the above sio2ObjectDuplicate method with 1.3.1.
I used the following code with the tutorial_6_1.
- Code:
sprintf( tmp_name, "%s%d", selection->name, numCreatedBalls );
_newObject = sio2ObjectDuplicate( selection, tmp_name );
NSLog(@"object duplicated = %s", _newObject->name);
if( sio2ObjectMapBuffer( selection ) )
{
_newObject->buf = selection->buf;
sio2PhysicAddObject( sio2->_SIO2physic, _newObject );
_newObject->buf = NULL;
sio2ObjectUnmapBuffer( selection );
NSLog(@"object added");
}
Afterwords I moved the new object to an other position with the following code:
- Code:
selection = _newObject;
btVector3 newPos;
newPos.setX(3);
newPos.setY(3);
newPos.setZ(3);
btTransform startTransform;
startTransform.setIdentity();
startTransform.setOrigin(newPos);
selection->_btRigidBody->setWorldTransform( startTransform );
selection->_btRigidBody->setActivationState( ACTIVE_TAG );
But the new object does not appear in the 3D world.
Does anyone have an idea?
Thanks

Re: Code Response(s) on features & Request(s)
Has this been committed to the source tree for future versions?

Maybe you are right, the sio2ObjectDuplicate method looks a little bit different:
- Code:
SIO2object *sio2ObjectDuplicate( SIO2object *_SIO2object,
char *_name )
{
SIO2object *dup = sio2ObjectInit( _name );
memcpy( dup->pos, _SIO2object->pos, 12 );
memcpy( dup->rot, _SIO2object->rot, 12 );
memcpy( dup->scl, _SIO2object->scl, 12 );
memcpy( dup->dim, _SIO2object->dim, 12 );
dup->rad = _SIO2object->rad;
dup->flags = _SIO2object->flags;
dup->bounds = _SIO2object->bounds;
dup->mass = _SIO2object->mass;
dup->damp = _SIO2object->damp;
dup->rotdamp = _SIO2object->rotdamp;
sio2StringCpy( dup->instname, _SIO2object->name );
dup->_SIO2instance = _SIO2object;
return dup;
}
The following code is missing or different and some member variables are renamed:
- Code:
sio2ObjectGetMatrix( _new );
strcpy( _new->iname, _SIO2object->name );
I tried it with the changes but my code still does not work.
Do you have any further idea?

Re: Code Response(s) on features & Request(s)
SIO2 v1.3.2 include objects databablocks, so all theses functions will be rewritten with new parameters and as well extend the flexibility...
The new revision should be out in a few weeks...
