[Solved, Thx] Start / Stop button, and a loop

[arkane]

I still don't understand why... Might someone help me ?

I'm back, sorry for the delay. A side note, you'll generally get friendlier people who might be more in a mood to help you if you don't constantly bump a topic- 24 hours is kind of the requested period around here.

My guess is that your game sets something within itself (like a hotkey or accelerator key) on F1...as likely as not, it's to prevent exactly what you're doing. (You may want to check the EULA of your game to make sure that bots aren't illegal )

Try another hotkey, or checking for _IsPressed() on F1 in a loop instead of assigning a hotkey. (sorry, missed your note about this above)

Edit: it would help a lot of you'd answer the question I asked last- what does HotKeySet() return if your game has focus (and therefore the HotKeySet() appears to fail)?

Maybe a low level Keyboard Hook using $WH_KEYBOARD_LL might work...

Look here for an example...

[arkane]

I don't really know how to check what hotsetkey returns.

I mean, hotsetkey works, its role is to say :F1 now runs this function.

And not : If you press F1, I'll run this function.

So indeed, if I set :

if HotKeySet("{F1}", "FocusProg") Then
            MsgBox(0, "Ok !", "Works...") 
        Else 
            MsgBox(0, "... !", "Doesn't work...")
        EndIf

Once the gui appears, I'm spammed of "Works..." Msgbox (my hotsetkey function is in a while loop).

I suppose I havn't understood what you exactly meant.

@KaFu : I don't understand how to use it, even with an exemple. I guess I'm not skilled enough to use hooks.

But I'm pretty sure that it is what I need, so I can detect "F1 key is pressed" at any time.

Edit : I've managed to adapt an exemple I found in the help file. I guess it needs some more modifications.

First: you shouldn't put the HotKeySet() in a loop; it only has to be called once at the top of your script to set it, and once later on if you want to un-set it.

Getting the return value of the function is the same as any other return value; either:

ConsoleWrite(HotKeySet("{F1}","FocusProg"))

or

$ret=HotKeySet("{F1}","FocusProg")
ConsoleWrite($ret)

will write to the SciTE console the return from the HotKeySet function. If it's a 1, then it thinks it worked, and it would be significant if it returned a 1 and yet still didn't work. If it returns a 0, it means that it couldn't set the hotkey at all, so it's guarenteed that F1 will not call your function. 0 usually means that another program (like your game) has reserved the specified key as it's own hotkey already.

It returns 1.

But the low level hook seems to work. I'm giving more tries.

Ok it works great with low level Keyhook. Thanks a lot to both of you .

No, you should base the movement of the character on the time elapsed, not the other way around (we did this in the 1980s and it sucked ).

Can you please give me more informations about how to do that ? I want it to work with the biggest precision possible.
