___________________________________________

I'm playing Strider 2014 and that's the code I had written for unlimited health, it works, but for some reason when I hit an enemy they don't really die... they just disappear, like poof, doesn't jump back to original code like its suppose to. I tried both of these as well:

cmp [rsi+308],2F
jne originalcode

cmp [rsi+308],27 //Enemy ID
je originalcode

still doesn't work, now it wouldn't be a problem with enemies disappearing but when I hit certain objects that trigger events, the events don't happen since the object poofs and I'd have to restart the level, can someone explain whats happening/ what to do?

Instead of this:

[vng21092]

If I write that then wouldn't unlimitedhealth_1 do nothing? Since it just jumps to returnhere_1? And data type was 4 Bytes with a value of 47, which in hex = 2F, I also tried

cmp [rsi+308],(int)47

got same result

[++METHOS]

Yes. But for testing purposes...what does it do?

The instruction that you are using for your injection point...what does it do?

Did you try comparing 8 byte value?

It seems...

possible problem 1: Compare is wrong or incomplete
possible problem 2: Other addresses are getting through (other than enemy/player health addresses), and need to be filtered out
possible problem 3: You 'health manipulation code' needs to change

Need more information.

[vng21092]

well changing it to jump to returnhere_1 didn't change anything, enemies and objects still disappeared, the instruction controls value of health for player, enemies, and objects (doors, switches, etc... yea... they have health ), in the data structure it said those values were 4 byte so that's just what I went by, but how would you compare 8 bytes? I didn't know that was an option, I always assumed numbers were the same in 2,4,8 byte and just used (int)#. I did however fixed the objects kind of, turns out they had a separate ID from the enemies, and I just added another compare and that ended up fixing one problem, I'm just confused as to why

cmp [rsi+308],2F
jne originalcode

doesn't work, if [rsi+308]!= (2F(playerID)) it should just jump back to the original code, isn't that how it works?

Try That for health

[vng21092]

@ThatLingon that code actually works really well so far, can you tell me how you found that instruction? Since when I try to find out what addresses it accesses I get nothing back except one address, which doesn't represent health. Also, what does this mean?

cmp [rdi+20],79616C50
db 75 1C

I get the compare, but whats "db"?

[ThatLingon]

Hi, well the instruction handles health, which i got from debugging health, and the damage to player, 1C0 Offset to current health 1C4 offset to max health.

I mov max health into current player health.
The DB 's i use is the equivlient to e.g. JNE / JE just using bytes insted here, used there to check if its player it then skips if not player and if player health is 0 it skips aswell.
or continues as normal.

[vng21092]

hmm thats strange, when I find out what writes to health I only get

"StriderX64_r.exe"+A40BB

I tried access but your instruction doesn't seem to be on that list either... =\
