I found on some site a strange way to declare a pointer. It goes like this.

Okay from reading this code I can see you posting a small amount of the full code.

I'm guessing NumPoint is the pointer, and what they are TRYING to do is to use DMA (DirectMemoryAccess) to edit the pointer, but that clearly fails.

it's just a reference. i am glad you find it so whimsical and amazing though.

It is a reference, and it's what you should be using instead of pointers whenever you can.

In fact, I just finished telling you so here: http://forum.cheatengine.org/viewtopic.php?t=472459

@Athaem
Why is it better to use references than pointers?
(I myself use them mixed)

If i'm correct another pro of this is that numpoint itself does not use up any stackspace to store the address of num

so while :

Wow, dark byte you satisfy me, I didn't expect that kind of answer from anyone. Again I learned something new. Actually I want to learn assembly and how the compiler translates all that stuff writen in high level languages to asm, but all the stuff I find to read is all very general and boring. I need something with specific examples to learn and all these details like the one I posted to be explained with a simple way. You know to have fun a little bit Very Happy

. I know you can make funny stuff with asm, and be the best programmer, but its hard to find a good document to read. If you could post a link please?
