Hello Carsten,
Thanks for the hint. I manage to correct that error.
But i am not sure if the design concept is efficient enough.
So i am attaching the snippet and hope that you can suggest
something better.
/*
the following switch is for
toggling between different light sources
attached only the spot light here
the rest of them used the same
procedure.
*/
switch(k)
{
//for spot light selection
case 's':
{
if(pLightNode->findChild(utahTransformNode) >= 0)
{
/*
utah is attached to point light
so detach it first
*/
cout << "Point Light is attached " << endl;
beginEditCP(pLightNode, Node::ChildrenFieldMask);
pLightNode->subChild(utahTransformNode);
endEditCP(pLightNode, Node::ChildrenFieldMask);
}
else if(dLightNode->findChild(utahTransformNode) >= 0)
{
cout << "Direct Light is attached " << endl;
beginEditCP(dLightNode, Node::ChildrenFieldMask);
dLightNode->subChild(utahTransformNode);
endEditCP(dLightNode, Node::ChildrenFieldMask);
}
if(sLightNode->findChild(utahTransformNode) < 0)
{
//light is not attached
//so attach it
cout << "attaching" << endl;
beginEditCP(sLightNode, Node::ChildrenFieldMask);
sLightNode->addChild(utahTransformNode);
endEditCP(sLightNode, Node::ChildrenFieldMask);
}
beginEditCP(dLight, DirectionalLight::OnFieldMask);
dLight->setOn(false);
endEditCP(dLight, DirectionalLight::OnFieldMask);
beginEditCP(pLight, PointLight::OnFieldMask);
pLight->setOn(false);
endEditCP(pLight,PointLight::OnFieldMask);
beginEditCP(sLight,SpotLight::OnFieldMask);
sLight->setOn(true);
endEditCP(sLight, SpotLight::OnFieldMask);
}
break;
Regards
Sajjad
