Hello and thanks for viewing this topic

I know that for 4 byte/integer value you place '#' or blank to define it
but what to do for others like double? I saw in youtube that for float you use (float) so I tried using (double) for double values but it did't seem to work

the code i am trying to change
Code:

movsd [edi],xmm1


what i edited
Code:

mov [edi],(double)6


BTW its a health and it is in double and full health is 6....if i do the code it just does like nop....doesn't decrease but stays whatever the value is
I want the hack to give full health as it is activated.HELP?
Did I do anything wrong?

Tim's Post:

line one & two
available in 64-bit processes.

about the last one, probably a typo
just use any register.

Sorry that is a typo, by using a 64 bit registry for a source or destination operand this will have it move 64 bits and just saves writing the QWORD PTR part, but this is only in 64 bit mode.

Code:
mov rbx,(double)1
mov [rax],rbx


Then the first one is mistake on my part.
And the second one is how to use a QWORD in 64 bit mode, when no source or destination registry is used.

EDITED:
For the mistake one the first one.

this is not possible, moving a qword value into eax register in 32 bit processes is not accepted.

because it take 8 bytes in memory, which is [eax] and [eax+04] however this is valid in 64 bit processes.

he is running a 32 bit process, then he must use the fpu x87 registers and instructions.

did you mean like this code? like fld which loads and fstp which puts into destination address
Code:

fld qword ptr [maxhealth]
fstp qword ptr [edi]

i understand that code but i couldnt understand rbx and rdx things which i have found in some games. is there any tutorial or guide.....if you could i would be happy

I was just tring to show both with addresses or registries, but the RDX was meant to be RBX.

this is the corrected code:
Code:
mov rbx,(double)1 // this is for 64 bit mode only
mov [rax],rbx


But if you are working in 32 bit mode just ignore it for now. And use the fpu x87 registers and instructions as OldCheatEngineUser said.

And this looks like it should work to me:
Code:
fld qword ptr [maxhealth]
fstp qword ptr [edi]

Those are just 64 bit registries, if you don't have a 64 bit game then you could use the 64 bit CE tutorial just to work a bit with the 64 bit registries.

RAX (64 bits) EAX (lower 32 bits of RAX)

having a 64 bit processor doesnt mean all your processes are 64 bit, remember 64 bit processor can run 32 bit processes.

the game you were running is 32 bit, otherwise CE wont bother you with compiling errors.

however you can avoid fpu x87 register and instructions, you can work with sse instruction set in 32 bit processes.
