Cheat Engine

[bensh]

Hi guys,

Again I have a question to ask.

Is it normal, that I can't find any adresses for a value in some games?

in one of my pc games I scanned for a value, and found about 100 or so.
but after the second scan the results are always 0, no matter which scanntype (byte, 1 byte etc..)

or does a way exist to find even such an hidden value?

I'am gratefull for any help. sorry to bother you all, but I still don't understand everything of cheat engine.

well as I said, after the first scan there are plenty of adresses cheat engine has found. but when I change the value in the game, and search for it in cheat engine, It doesn't find anything anymore.

If you are searching for an integer try scanning for a float, and vice versa. Floats and integers are formatted differently, but you cant tell them apart just by looking at their raw values.

A few games hide certain values to prevent cheating. Simply XORing a value with a known other value effectively hides a number from simple scans, and is extremely fast so there is no performance penalty to the game. You may have to just alternately scan for value has changed, and value has not changed, not giving it a value to search for. If you do find it, you would need to find the known value (which on rare occasions could change each time the game writes to it), and inject custom code to change the value instead of just injecting the value.

Even worse some games actually move the location of variables around during runtime. One of the supplied tutorials deals with that problem, if i remember correctly.

Try doing a double for it, then scanning for that number or what he said up there.

I already tried everything like (byte,2byte,4byte,8byte,double,float) but found nothing. well i guess it can't be helped. maybe because it is an emulated game

[Dark Byte]

tried an unknown initial value scan method ?

anyhow, in emulator games I recommend setting to 1 byte value
And if the value is bigger than 256, just ignore that (it will convert to a less than 256 automatically)

I tried this one out again in some games and noticed something. there are values than can be found, and others that can't be found.

for example I found values for str,dex and so on, but I could not find values for hp and mp. maybe this game was programmed so It can't be hacked for some values?

so the hp value I was searching for all the time, still can't be found )= but I was able to change the value of my hp potions =)

so thanks to you all no more help in this topic is needed so far, maybe I'm able to find such values that are hard to find some day when I'm deeper into the topic (I'm still new to ASM )
