 |

I'm searching for some bytes (2) in HOMM2, using 6.1.
I know from previous work that a heroes max movement is h27 from name and cur movement h2B. So I searched for a name and found the location for the name and copied those two addresses.
I'm trying to find where the program has the movement values so I did a search of the game for the max and cur (equals max since there has not been movement) values listed in the table. To my surprise the values in the table do not show in the search results. I thought there may have been a conflict, so I closed CET and the game. Started up each, found the name and the movements, searched for that value again and the same behavior was observed the addresses in the table were not listed in the search.
Stupid question but what am I doing wrong?

If I understand that correctly, you mean that the address for current movement always ends with 0x2B. In this case your problem is memory alignment. See the "fast scan 4 alignment" part in cheat engine? It means that cheat engine will only scan addresses that are a multiple of 4, and guess what, an address that ends by 0xb=11 isn't a multiple of 4.
Technically only looking up addresses that are a multiple of 4 is justified in 32bit applications since allocated memory will always be 4 byte aligned unless a specific option is set making the program.
tldr: disable the "fast scan" option.

I guess I didn't give a clear description of the issue. Refer to document attached:
You will see Hero "Alamar" with 2 2 byte locations beneath one at h27 and the other h2B from his name.
Now look at the search results the addresses h02B67F15 and h02B67F19 are NOT in the scan search, and that is what I was trying to explain.

Thanks for the clarification, the scan works properly, bt I'm not sure why disabiling the fast scan makes a difference.

Fastscan skips unaligned memory because properly designed games would never store values unaligned since it's slower to access by the cpu.
This game does store the values unaligned which is why you need to disable fastscan so ce also scans that
