Hi! I have never worked with memory before, and now I need to copy one awway to another on every frame. So.

Do I have to allocate memory on every frame?
Like

-- Allocate memory for array b
-- Copy array a to array b

or just allocate memory once and then copy all the time?

Or maybe this way?

-- Free space, if b already exist
-- Allocate memory for array b
-- Copy array a to array b

Or I have to free memory only on application close? Would not be there any memory leaks when I copy all the time?

Only allocate the memory once, and free it at the end of the game.

Thanks! But do I have to allocate memory, if I use memcpy only?
Currently I have this function, but is is not working, though I get no errors

I guess it is not that simple..
I'm trying copying those arrays for a long time, still it is not working.

I have found this in the manual:



This is only info regarding arrays, and so I'm using formula to get size.

Maybe arrays have some more restrictions, their memory is not aligned well, they can not be copied this way, and I'm wasting my time?

I think the problem is this:

sizeof(var) * MAX_CELLS * MAX_CELLS * 3

there was a thread and also a mention in the manual that it does not work this way. Try

(int)sizeof(var) * MAX_CELLS * MAX_CELLS * 3

or simply

4 * MAX_CELLS * MAX_CELLS * 3

Thanks a billion! I've searched all topic, just how could i miss it?
