Hi. Is the memory deallocated automatically? Or I must delete all the sprites-bitmaps-images that I load and create?

Thanks for helping, I'm new at this.

When the program exits, DarkGDK automatically deletes anything with an id number. (So objects, sprites, bitmaps, images, etc.)

Even if it didn't windows XP and above automatically frees all resources owned by a program when it exits anyway.

I believe DarKGDK only released resources by itself when using the default "Escape key to exit" behavior.

As stated above Windows should deallocate your resources, if it doesn't you could (and probably even should) create a function that deletes all your resources for you when you press your game "quit button".

Its good programming practice to release anything you create.

An init function to create

A shutdown function to release

Thanks, I'm going to deallocate everything manually, just to be sure...

Bear in mind that some of the text input functions return pointers to dynamically allocated space for the zero terminated string. If you're going to handle everything manually then you need to do

delete [] txtPtr;

or whatever the pointer is. And don't reassign the same pointer to another input until you've deleted any previous assignment, otherwise you get a memory leak for the duration of the program.
