Hello all.

Quick question.

I create a sprite with ID = CreateSprite(whatever), and an ID is returned. Later, I might delete that sprite, and then create others afterwards.

My question is this. Is that ID ever used again by AppGameKit when creating another sprite? The ID numbers keep increasing, but theoretically what happens when we hit ID 2147483647 (the highest 32-bit number)? Does AppGameKit roll back around to the first unused (deleted) ID? And is this behaviour the same for all resources (sprites, memblocks, images, etc.)

I know it's unlikely that I would create 2,147,483,647 of anything, but if, under certain circumstances, AppGameKit reuses an ID, it could mess up the code I'm working on.

I guess what I'm asking is are there any circumstances where AppGameKit would reuse an ID it had used before, if that resource had been deleted.

Thanks,

James

If you delete the sprite and AppGameKit renames another sprite with the same ID, you have nothing to worry about.

let's assume you're not doing that.

Your GPU would run out of memory long before AppGameKit could duplicate a sprite. I have dealt with that bug before(accidentally creating an infinite loop of sprites). My GPU just gives out. I can't remember the exact error, but its something like "Your GPU has run out of memory".

Or you could just test this by creating a bunch of invisible sprites?

I don't think ID's are ever reused unless you call DeleteAllSprites().

ID's that are created by AppGameKit start at 100001 and increment up by one for every resource of that type allocated up to a max value then it wraps round to 1 again.

AGK will NOT allocate an ID for an item that is currently being used. So as you have said it takes the first unused ID greater than the last one used. If you did allocate and delete a sprite 3 billion times it would wrap back round to 1 and start counting up again but it will miss out any ID's that are currently being used (ID's that have not been deleted) . If you let AppGameKit allocate the IDs for your resources then you shouldn't have any problems at all even if you did happen to create and then delete 3 billion times over.
