Dropping nodes

[Quantum1982]

Hi

I am making a maze game in 3D which uses a bunch of CubeSceneNodes. Now I want to be able to delete a specific cube scene node in certain circumstances.

I tried using drop, but then the system crashes. Am I missing something obvious ?

Cheers

Works the same as all reference counting in Irrlicht: http://irrlicht.sourceforge.net/docu/cl ... unted.html
If you didn't create it with a function starting with the word "create" or created the object with new or did grab() it at some point you should not drop objects.
What you most likely want to do is remove it from the scenemanager, which you do by calling remove() on your node.

Thanks for the reply

I tried this

Code: Select all

 
if (HumanNode)
                        HumanNode->setPosition(core::vector3df(500+(500*Human.iX),200+(500*Human.iY),500));
 

to try and get rid of the crash that I get when I call this :

Code: Select all

 
else if (receiver.MyEvent.KeyInput.Key==KEY_KEY_R)
                {
                        HumanNode->remove();
                }
 

This was just a test to see if it gets removed, but the program still crashes ?
What else am I missing ?

Cheers

Safer way:

Code: Select all

if (HumanNode)
{
    HumanNode->remove();
    HumanNode = 0;
}
 

It's better to run the program with a debugger to see where it crashed.

Also you may try deleting using

Code: Select all

void irr::scene::ISceneManager::addToDeletionQueue(ISceneNode* node)

maybe will help you.
