Really, if you have the value that you want to change, just inject code at an instruction that accesses a keyboard key or controller button, and tell it to increment/decrement your value if the keys/buttons are being pressed.

If you insist on injecting at the instruction that handles your speed value, then you will need to filter out all of the unnecessary addresses.

EDIT:
Even further, all you really need are the address and pointers of three values: the speed, controller button #1 and controller button #2. You can inject your code at any instruction that is being accesses a couple of times per second - it can be any instruction in the game.

If multiply by 3 goes too fast, then try something smaller, like 1.3 or 1.003

You can write

Yes, you don't need to multiply anything. You should listen to advice and let people help you instead of focusing all of your energy on something that obviously isn't working.

Anything that you do not understand, just ask. When you ask a specific question, you will get a specific answer...as you can see. However, sometimes it is better for us to ask questions to better determine what it is that you are trying to do because the approach that you think is correct may not be correct or ideal.

OK, I saw that example from twitch.tv


You must find out how to filter out other addresses.

First, try this:
1. find address with your current vehicle speed.
2. do "find out what access ...".
3. just below "instruction" column, in that empty space, right click and choose "check if found opcodes ...."
4. go to game drive for a while
5. window "the following opcodes ...." should fill with data
6. make screenshots of whole window. Resize that window. And be sure that count column is wide enough. So we can see all entries. (you can shrink bottom list)









BTW.

addss xmm0,xmm0

is the same as:
sub esp,04
mov [esp],(float)2.0
mulss xmm0,[esp]
add esp,04
movss [eax+30],xmm0


Yes, the first one is easier, but what if you want to multiply it by 1.5 ??



EDIT:
try this code:

[shadowpt]

Alright I tried the adss xmm0,xmm0 and it "freezed" that axis movement, basically it is taking the final value and replacing itself with it, this means that no other value is added to it or decreased.

I also tried the assembly suggestions with and without limiter

Probably, you get it wrong.

Try this table:
1. open table
2. attach CE to game process
3. enable script
