m_paCClasses = new CClass * [numberOfClasses] ???
Author
Okay, this is kind of like another recent post but I am still lost on what to do in my situation. I have an array of pointers to animations used by a class...
CAnimation ** m_paAnimations;
...so when I allocated memory with new I did the following...
m_paAnimations = new CAnimation * [numberOfAnimations];
...which doesn't seem to work. Can someone help me with this? It shouldn't be to hard, I just don't get why this wouldn't work.

What do you want? An array of pointers to CAnimation or an array of CAnimation objects? i.e. what is the data type of m_paAnimations?
If you want an array of objects, m_paAnimations needs to be of type CAnimation* and you allocate like this:
and delete like:
If you want an array of pointers (not sure why as you are not clear on the application), then m_paAnimations needs to be of type CAnimation** and you allocate like this:
and delete like this:

Sorry about not being clear, m_paAnimations is an array of pointers to animations. So by what your saying...
m_paAnimations = new CAnimation*[numberOfAnimations];
..should work, but it doesn''t seem to, so maybe I have some other problem. In regards to allocating each pointer I have another function doing that. Should I rewrite so its not in another function or is what I have okay?

It would be helpful if you can define what you mean by "it doesn''t seem to work"...is it not compiling?

Okay, I was just looking through my code and I realized I wasn''t allocating memory for the pointers in the array. That fixed the problem. Thanks, that had me stumped.
