void The_Asteroids::AddAst()
{
Tail = Tail->NewAst(Tail);
}
An_Asteroid *An_Asteroid::NewAst(An_Asteroid *curr)
{
if(Next==NULL)
{
Next=new An_Asteroid;
Next->Prev=curr;
Next->Next=NULL;
return Next;
}
return NULL;
}
Why doesn't this work?

I''m learning linked lists (no STD, just basic linked lists), and I''m attempting to add a new node at the end of list. No matter what I do, this freezes my computer!
this is the code:
The_Asteroids class is the list of An_Asteroid class. It have Head, Tail, and Current. An_Asteroid is storage for data on each asteroids, sort of like an array.
When this is called, the game freezes, along with my computer. Can you explain why this is happening, and what is the correct way to do it?
Thanks

Zeraan:
I don't think you can return class objects. You should probably have the NewAst function return a pointer to the next item on your linked list. Maybe something like this:
In addition, in your code, you had the function try and return both Next and NULL if curr == NULL. I'm not sure what the legal compiler response would be in that case.
