I want to change value but:

Value is double and exact but when i try to change it nothing happen. So i clicked browse this memory region and found out that previous adress change value but not in value i want. Ingame value is 217764852 but in memory i get -1.47535813557939E-106.

I also tryed with whats writes to this adress and when i nop adress value just start counting down or up depends on adress really fast (like millions), so i cant really change it that way.

How can i change this to get normal value?

If the change has no effect, you got the wrong address.

Why do you mess with the memory editor?
Change the value in the table.

I always got 2 adresses and both turn back in table when i edit it.

Just like i explained in picture.

adress 1C832DF56B8
and 1C832DF56D8 in this case
i got this 2 in table and it turned back. but if i got from 1C832DF56B8 1 byte back (yellow color, i think it is 1 byte), i can edit value but result is always random so i cant do a fixed value.

Maybe it would help if you could share what game you are approaching, as well as what that address is supposed to stand for?

Well, if you are certain, then you're certain.
Maybe the value is encrypted/protected somehow.

So game is bloons td 6 and value is ingame money for buying characters (not green money for powers and other premium stuff)

In easy mode i start with 850$. I search for 850/exact/double, when i got 2 adresses (it is always 2), i change value and iven if i select both money does not change. So i tryed with access/write and noping some out then change but still nothing. Then i got to memory View now look at picture

lets say i got ingame money value 1350

so xmm1 and xmm6 are same value so money value

Dont worry about that anymore it seems that hack is working but i cant edit to specific value i want cause of some encription, and is it not so annoying. Just need few tryes to get money above value i want.

See, that code that run 4000+times, I think that's the check and correction on the value.
The one where you see XMM1 and XMM6 with the same value, that could be the real update.
Trace back and see where that XMM1 comes from, and update it as soon it gets its value.
That should work.

Well thx for help. I found uncrypted value. I basicly started with mov rax,[rbx+28] because it poped out later when game start to do its thing so i dont know if adress that runs 4000+ times will lead me to same value.
After few brake and traces i finally found original value.
