Test if object == NULL

[Brutile]

I have an object declared in a header file in C++ as follows:

Model* model;

 

How do I check to see if it is null?

 

I've tried:

if(model == NULL) and if(model == nullptr)

 

But it seems the object exists, but is not created, therefore it will always be true.

Then when I go:

model->Release();

I get an error.

 

So, how do I check if it has been created?

You're not initializing the pointer. If you do it like

 

Model *model = null;

 

then you'll be fine. Depending on your compiler, they don't always init pointers to null.

There's something wrong with the model->Release(). Is there a better/proper way of removing a model from the world?

Because I'm checking if it exists, then trying to remove it to recreate another model in its place.

Ok, It was my fault all along

I changed a pointer to another position in my array, then deleted the old one, which was still used.

Then when I tried to access model, it wasn't there.
