Cheat Engine

[kik4444]

Hey, I know I already made a topic about this, but is something else and I need a veteran's opinion on this. So this is a code for a game where my and my enemies' health is stored in the same code. So I found the base addresses and compared them and found an offset which I'm pretty sure doesn't move and I used that to compare it to. I made the code something like (the game kept crashing so I recreated it on memory) this:
[ENABLE]
//code from here to '[DISABLE]' will be used to enable the cheat
alloc(newmem,2048)
label(returnhere)
label(originalcode)
label(exit)

newmem: //this is allocated memory, you have read,write,execute access
//place your code here

cmp [esi+1F1],00000001
je exit
jmp originalcode

originalcode:
movss [esi+eax*4+00000384],xmm0
jmp returnhere

exit:
movss [esi+999999999999],xmm0
movss [esi+eax*4+00000384],xmm0
jmp returnhere

"Injustice.exe"+9304BF:
jmp newmem
nop
nop
nop
nop
returnhere:




[DISABLE]
//code from here till the end of the code will be used to disable the cheat
dealloc(newmem)
"Injustice.exe"+9304BF:
movss [esi+eax*4+00000384],xmm0
//Alt: db F3 0F 11 84 86 84 03 00 00

But when activating this and when I hit my enemy or if he hits me, the game instantly crashes to the desktop without an error report. Is there something wrong with the code?
In EXIT if I were to do it like this:

mov xmm0,#999999

CE refuses to compile it.

Yes. I want to put that number into xmm0 or at the very least freeze it in the script. I tried both freezing it and doing it like this:

movss [esi+999999999999],xmm0

but both times the game crashes to desktop without an error report when I hit my enemy or if he hits me.
BTW, when I say "Freezing it in the script", I mean doing it like this:

//movss [esi+eax*4+00000384],xmm0

but both times the game crashes

[zm0d]

ESI+999999999999 will access an address totally out of your processes memory. That won't work. I edit my upper post right before you posted. Take a look at Virtual Address Space.

Hello. You made a few mistakes here. For example,

[kik4444]

I'll try that out later, right now I have to go to school. I'll report back to tell you if it worked and +rep you if it did

[kik4444]

I think it'll be a long time before I learn to script like that, so for now I'm just looking for a way to make it work with a simple script without any side-effects. BTW I'm finally back from school and now I'll try ColdFusion's method and I'll report back with my findings.
EDIT: I'm gonna try something else, but for now I did it like this:

[ENABLE]
//code from here to '[DISABLE]' will be used to enable the cheat
alloc(newmem,2048)
label(returnhere)
label(originalcode)
label(exit)

newmem: //this is allocated memory, you have read,write,execute access
//place your code here

cmp [esi+1F1],00000001
jne originalcode
push eax
mov eax,99999
pop eax

originalcode:
movss [esi+eax*4+00000384],xmm0

exit:
jmp returnhere

"Injustice.exe"+9304BF:
jmp newmem
nop
nop
nop
nop
returnhere:




[DISABLE]
//code from here till the end of the code will be used to disable the cheat
dealloc(newmem)
"Injustice.exe"+9304BF:
movss [esi+eax*4+00000384],xmm0
//Alt: db F3 0F 11 84 86 84 03 00 00

and nothing changed
EDIT2: Ok, so I did it like this:

[ENABLE]
//code from here to '[DISABLE]' will be used to enable the cheat
alloc(newmem,2048)
label(returnhere)
label(originalcode)
label(exit)

newmem: //this is allocated memory, you have read,write,execute access
//place your code here

cmp [esi+278],00000021
jne originalcode

push eax
mov eax,1065353216
movd xmm0,eax
pop eax

originalcode:
movss [esi+eax*4+00000384],xmm0

exit:
jmp returnhere

"Injustice.exe"+9304BF:
jmp newmem
nop
nop
nop
nop
returnhere:




[DISABLE]
//code from here till the end of the code will be used to disable the cheat
dealloc(newmem)
"Injustice.exe"+9304BF:
movss [esi+eax*4+00000384],xmm0
//Alt: db F3 0F 11 84 86 84 03 00 00

and it worked!!! I don't know what happened before tho, I guess I maybe not have been comparing it to a static value. But now it works anyways, thx again. I'll give you +rep once my rep timer runs out

[podstanar]

You forgot one crucial line, take a look at my post above: movd xmm0,eax
So the code would be:

[kik4444]

Oh and for the record, can this same script be used to make a one hit kill script by making it compare the enemy's health and setting it to 0 like this?:

cmp [esi+278],00000023
jne originalcode

push eax
mov eax,0
movd xmm0,eax
pop eax

[podstanar]

Actually it can. However, if the injection point is accessing only you and your enemies (excluding other possible objects), there is no need for an additional compare. Just redirect filtered addresses, and you will get Infinite Health + One-Hit Kill.

Example:

[kik4444]

I was talking about if it's possible to make a separate script for one hit kill.

[podstanar]

Read my answer above carefully, you should notice that i provided an answer to that question: It can be done.
Side-effect: You will not be able to activate both cheats at the same time. That's why i provided an alternative.

[kik4444]

Well I suppose that's enough, thx. I'll +rep you when my timer runs out in around 1.6K seconds.
