hello guys I need some info it has been years last time I scribbled with assembly but recently started again now I have to get all the gears straight again...
what I struggle with in particular is that I saw this video from Mr.Stephen Chapman I like watching his tutorials, now this video
shows how to create a thread on how to make anything regenerate..
I have tried it on this game Vampyr but with no success well at least I got it right but the problem is that the value I have is a float and not 4 bytes now the value is counting up in 4 bytes instead of a float if anybody would be so kind is to take the script i have and show me how to change it so that it recognizes it as a float not 4 byte would be much appreciated
thank you in advance...

Inc works for integers, not floats.
Use addss instead.

Read this to explain using floats: https://wiki.cheatengine.org/index.php?title=Tutorial:CodeInjection_Floats

[panraven]

The pointer address [[BloodBase]+f8] in mov rax,[[BloodBase]+f8] will only evaluated ONCE while the script activated,
which may be error-prone if BloodBase might change; it is better use a register to hold the value, and use as pointer only if the register value is valid <eg. non zero>; then

Thanx for the reply guys...
I have tried your guys' methods but have failed but I will Practice making threads seems like I have to play with it a more to understand it but I have succeeded doing it the old way....

newmem:

code:
push ebx
mov ebx,[rax+F8] // cap of the blood
cmp [rax+100],ebx ////Here I want to cmp value with cap then jmp
to wait
fld dword ptr [rax+100]
fadd dword ptr [bloodinc]
fstp dword ptr [rax+100]
pop ebx
jmp return


originalcode:
movss xmm6,[rax+00000100]

bloodinc:

BloodRegen:

nop 3
return:
registersymbol(BloodRegen)

[DISABLE]

BloodRegen:
db F3 0F 10 B0 00 01 00 00

unregistersymbol(BloodRegen)
dealloc(newmem)

but now I dont know how to put the timer delay this way...want the blood value to increase by one float every 2 seconds until it reaches the cap value...
I feel I have to let you guys also know that this instruction is where it is constantly reading

[panraven]

If your inject point run every frame

Thank you very much im so hype that I have learned something new....struggled with this for days....thanx man apreciate it ....couldn't thank you enough....

This was my old Blood Drain mod script for Vampyr.
I doubt it still works, and it's not treaded, but it might give you some hints.

[SigmaWolf-.-...]

last Question guys
it works 100 % only problem I have now is when I compare it it kicks me out of the game I need the script to stop when it reaches its cap my script looks like this now

label(code)
label(fpscnt)
label(originalcode)
label(bloodinc)
label(return)

newmem:

code:
push rbx
mov rbx,[rax+F8] <<<<this is Cap
cmp [rax+100],rbx
//if I place jump in here it kicks me out of game
inc dword ptr [fpscnt]
and dword ptr [fpscnt],01f
jne @f
fld dword ptr [rax+100]
fadd dword ptr [bloodinc]
fstp dword ptr [rax+100]
@@:
pop rbx
jmp return


originalcode:
movss xmm6,[rax+00000100]
jmp return

fpscnt:
dd 0

bloodinc:
dd (float)1

BloodRegen:
jmp newmem
nop 3
return:
registersymbol(BloodRegen)

thanx again guys
and one last thing where can I read more about this so that i can learn more out of it how it works or represents

inc dword ptr[fpscnt]
and dword ptr[fpscnt],01f //// zero flag every 32th execution, 03f for 64 frames, 07f for 128 frames
jne @f /// only do inc when zero flag occurs
fld dword ptr [rax+100]
fadd dword ptr [bloodinc]
fstp dword ptr [rax+100]
@@:
pop ebx //// should use 64bit reg push rbx
jmp return
fpscnt:
dd 0

What the script with the problem jump?
btw, you can enclose CODE with [ｃｏｄｅ]<code-text>[／ｃｏｄｅ] to make <code-text> look more like code (not nest-able).
([ｃｏｄｅ] is in unicode to escape from the formating, don't just copy and paste, type it as normal acsii char in the text box editor)

btw the compare to max should make AFTER your INC, else if max is make, the final value may/must be over max.

For individual x86 assembler instruction (what each instuction do), may be this https://www.felixcloutier.com/x86/ , it's more like a convenient online manual.
For AA script usage as assembler, may read other active cheat maker's uploaded ct file from fearlessrevolution.com

[Csimbi]

I don't get it.
What's the point of adding some value?
Why not just use the cap directly?

Sorry i dont understand this concept...how would you add this into my script ???Sorry im kinda new to this new ways

I geuss i cant jump because i think this script is made where the code. is constantly reading not wtiting i think that might be the problem ....

To awnser your qeustion why i dont want cap to write in my normal blood value is the same Panraven gave you but also I do the aseembly for the fun and to learn sometimes i dont even use the cheat I just like doing it....thank you guys for your tremendous help coulnt have done this without your help...

[panraven]

I mean MOVE the cmp code after inc code.

[SigmaWolf-.-...]

Thank you very much guys I appreciate it it works now 100%
you have taught me much with this...just shows me no matter how much you think you know there is always more to learn...thank you Panraven and Csimbi
I will use this technique much more now...Thanx again for your help
