i think the problem with this "INJECT - jb WoolfeGame.exe+575C7 "
coz it jumping to the opcode that i nop it

Of course it crashes... Look at the unconditional jump right before your inject instruction... Since you also take the following instruction (mov rbx,[rsp+40]) into your script, the jump executes code rubbish because it'll jump somewhere into your own jump instruction.

i think there's no problem with (mov rbx,[rsp+40])
coz i thought the game will crashing if i take it so i didn't nop it by doing this

In your screenshot, you can see the green arrow points to instruction mov rbx,[rsp+40]
The JMP from your injection takes up 5 bytes while the first instruction you overwrite only takes up 4 bytes.
This means that when that green-arrow JMP occurs, it is going to jump to the 5th byte at the end of your JMP statement.
That is causing the computer to read that byte as the start of the next instruction to execute.
As you can imagine, it's going to throw off the whole execution and cause a crash.

Move your injection point up to the instruction: movss xmm1,[rsp+50]
You can simply replace that with: movss xmm1,[rdi]

hi Zanzer
that what i was need ! i try to disable the adding to the xmm1 from the beginning but i didn't know which opcode i should choose
now can u give my the way that i can add this value to xmm1
value = 3F800000 "<-- it is in hex like u can see
i need to change the value to this 3F800000 coz u when i enable the script the and i trying to pressing the button from the keyboard value inc instead of dec
and that what i want but ! when i let the button the value back to the same value before increasing
i tried this but it didn't work

I'm assuming you're talking about the same address?
