Whenever I run my code under release build, it seems to go perfectly. All is well, until I decide to exit the program. As soon as I try to close it in any way the thing crashes, giving me

"Unhandled exception at 0x00001b60 in Prog.exe: 0xC0000005: Access violation reading location 0x00001b60."

I looked around the forums and it seems like the thing to do would be to watch the output in debug mode to see if vc++ is averting access violations and where, but I have no such warnings.

I've also looked around all of my exiting code and I do not see any potential violations there either. All of my pointers are still in my possession before I try to delete them, so unless DarkDGK is up to some mischief (unlikely), I figure it must be some sort of issue earlier in my program that for whatever reason does not trigger until the end.

Is that possible? If not, or if it is but there is a more likely solution, I would be grateful for any imparted wisdom.

Could you post some of the code? That would help.

The only thing that caused me to have that kind of problem was using an OOP object that encapsulated a sprite or image when an object of the class was declared as a global. The destructor tried to call a db* function after Dark Basic has removed its support.

Hmm, I don't have any classes that use engine functions in their destructors. Here is the code called on exit.

The game loop:


The game "destructor"


I confess, I only have one week of C++ under my belt, and I am by no means certain that this is the correct way to delete classes in arrays. I made them individually with "new," so I figured that deleting them individually was the right approach.

Are player and ent pointers? You can only delete pointers, as far as I know.

Aye, so they are. The Player class does nothing with DarkGDK itself, whereas that is the primary use of the Entity class. However, I never tell the entities to release their sprites/particles/objects when I delete them, as I'm pretty sure the engine takes care of that for itself.

It may be of some import to mention that the player and ent arrays are both global variables declared at the top of the cpp file where I define the Single_Game_Destroy method. Might that perhaps be the source of my ills?
