I'm using the dissector with great success to map out the unit structures in a game.

The unit inventory is 4 2-byte words. I can define this separately, and assign an offset in the Character structure to be a "InventoryItem", but it doesn't display in a meaningful way in the Character Structure, just 4 bytes hex.

I am I doing something wrong? Or is it not supposed to be able to expand the substructure items?

Many thanks

Not really sure what you mean with substructures or what you're doing.

If you want 4 2 byte words you just add 4 times a 2 byte element at the required offset
Only if it is a pointer you can expand it

I guess to rephrase my question...

In the structure dissector, under "Change Element", there's a drop down box that you define what the element should be, e.g. 2 Bytes, 2 Bytes Signed, etc.

At the end of this drop down box there are the named structures that you've defined.

What can you use these for?

It should paste in the contents of the structure at the new position. so if the structre you've selected exist out of 2 byte elements, it 'should' add them there. But it might not be working. (and that function is gone for next ce version)

Ah, interesting thank you. It doesn't seem to be working for me.

Is there somewhere you prefer bug submissions?

I think I came across a bug in the auto-assemble, I was trying to make an array of character pointers using:

mov [cArray+4*index], pointer

But it was only adding index to cArray, not doing the multiplication. I was able to achieve my desired result by doing a mul "manually".

bugreports can be posted here: http://cheatengine.org/mantis/view_all_bug_page.php so I don't forget about them

also "mov [cArray+4*index], pointer" is invalid if you did it just like that

[cArray+4*index] : index MUST be a register. It may never be a value or address. And if it then doesn't do the multiplication there's something wrong with your cpu... (and if you just wanted the address, look up lea)
