Vector of SimObjectPtr corrupts memory

by William Todd Scott · in Torque Game Engine Advanced · 08/12/2007 (12:04 pm) · 3 replies

Hi,

I have a class with a data member that is a vector of SimObjectPtrs to datablocks as such:

Vector> mDatablockList;

However, when this class is deleted memory gets corrupted.

I was wondering if anyone knows why this might be the case?

At first I thought it was because the destructor for tVector calls free() without calling the underlying destructors for its objects. However, I tried emptying the list before the tVector destructor is called and I still get the corruption.

Thanks
Todd

Edit: Actually, VectorPtr isn't at all what you want. It wouldn't call the destructor on the SimObjectPtr, and that would be bad.

Hey Pat,

Thanks for the response.

Right now I am just using VectorPtr, which works, but unfortunately loses the benefits of the SimObjectPtr.

I don't quite get why Vector's use of constructInPlace and destructInPlace would be problematic with the SimObjectPtr, since it is an object and it has a default constructor defined.

Thanks
Todd

Vector should be working, is the thing. I am not sure why it isn't. At first I thought this was the standard Vector/VectorPtr confusion. I checked to see if I was using a vector of SimObjectPtrs anywhere, but the closest I have is a Vector of a struct with a SimObjectPtr inside.
