[Plib-users] ssgSelector question

[Allen Y. <ay...@wr...>]

Hi,
I have a question about using ssgSelector. I set up menu selections for the
user so they can switch differnt objects.

in my main root class:
I am doing the following things:
scene1 is ssgRoot.

if (!m_OS_flag)  {
	scene1->addKid(m_pOSBranch->ReplaceShipMode(shipMode));
	m_OS_flag = TRUE;
}

if ((shipMode) != (m_shipMode_flag)) {
	scene1->addKid(m_pOSBranch->ReplaceShipMode(shipMode));
	m_shipMode_flag = shipMode;
}

m_pOSBranch->update_OS_motion(localX,localY, localZ, Heading);

In my ship  class, I try to load the different objects based on the user's
request:

ssgEntity *OS_obj2, *OS_obj;

ssgTransform *COSBranch::ReplaceShipMode(BOOL &shipMode)
{
	if(m_OS == NULL)
		m_OS = new ssgTransform;

    ssgModelPath   ( "../data" ) ;
    ssgTexturePath ( "../data" ) ;

	if (m_pStateSub == NULL ) 
		m_pStateSub = new ssgSelector[2];

	OS_obj = ssgLoad3ds ("latestSEAWOLF.3DS");
	OS_obj2 = ssgLoad3ds ("02carrier.3DS");


	m_pStateSub[0].addKid(OS_obj);
	m_pStateSub[1].addKid(OS_obj2);

	if (!shipMode)
	{
		m_pStateSub->selectStep(1);

		m_OS->addKid(&m_pStateSub[1]);
	}
	else {
		m_pStateSub->selectStep(0);

		m_OS->addKid(&m_pStateSub[0]);
	}

	return  m_OS;
}

My problem is that the old object didn't get deleted when the new objects
load into the scene. How can I solve the problem? Please help me out
