So I have been using new a lot for my game because I am declaring pointers to some of my game objects and then initializing them later like so:



Now my question is do I call delete after the game is over like lets say the player quits out to the main menu is that when I should call delete?

Also I have a lot of enemies that I do that with should I call delete whenever they die or just when the level is done?

One last thing, if I were to call delete based off if the enemy is alive would I have to make a bool to make sure that it only tries to delete the memory once for example:


If I ran that and then the next time it looped through my game loop it would come to this line and try and delete it again. I would really only use this if you are supposed to call delete right when an enemy dies.

Anyway I really appreciate any help that can be given. =)

You should delete it when you no longer need it - that just depends on the structure of your program.

If you have a lot of enemies, you may want to reuse them. It's safe to just delete them when they die though and spawn new ones separately.

Try this code for not deleting something twice:

Cool thanks I just wanted to make sure that I understood when to delete things. Seems like I am on the right track from what you said.

I have a question on header files. I have a header file that includes all of my games header files, looks like this:



Now for lets say my individual classes like Box.h would it be inefficient to just include this header file into that class knowing that I wont be using a good majority of these include files in that class. Or does it really not matter and I can just add any new include files that I have to IncludeAll.h and just use that for all my new files?

Generally, you only want to include what you will use in that class and forward declare classes as much as possible. Kinda like this:
