 Posted: Wed May 29, 2013 11:56 pm Post subject: understanding GetAsyncKeyState |
 |
|
I have an asm script where i want the effect to only take place when a key is held down. From what i understand you use a push before the GetAsyncKeyState to set up the key used but im not sure where to go after that.
i have this for when i hit control.
push 17
call GetAsyncKeyState
Im not sure what is needed afterward to make the compare work. I'm probably missing something really simple. |

The AX register will hold the result
If bit 0 is 1 that means the key is down at this moment
If bit 15 is 1 that means it has been down since last time this thread called getAsyncKeyState (might already be up)

I have windows XP x64 SP2.
Cheat engine (v6.3) says:
"Error in line ## (call GetAsyncKeyState):This instruction can't be compiled"
wherever "call GetAsyncKeyState" is present.
maybe someone knows what to do with it?

It will work only after you attach to process. (and if process imports that function)

hmmm. That looks like it may be the cause...
I have googled and found out that "GetAsyncKeyState" uses different return values on x32 and x64 systems. But all solutions found are for C# and java.
And this is no java

This is probably irrelevant for now. In your case, CE has problem to recognize the GetAsyncKeyState instruction which means that it has probably not found the API. You have to check that CE was able to find the API. If you use "Go to address" and give GetAsyncKeyState as destination, CE will jump to it. If not, then something is wrong.
