Mouse Moves When it shouldn't

30 posts in this topic

the code below reproduces a problem where the mouse moves one pixel to the right.

? why? - 


While(True)
    Sleep (1500) 
    Local $x = MouseGetPos(0)
    Local $y = MouseGetPos(1)
    Consolewrite(@CR & "x  >" & $x & "<   y>" & $y & "<")
    MouseMove($x,$y,0)

WEnd

philkryder,

When does the mouse move?  I ran it as follows...

hmm -

when I saw the problem, it was on my machine at work, where I have 4 monitors.

I just ran it here at home with only a single monitor and it works just fine....


x  >415<   y>372<
x  >415<   y>372<
x  >415<   y>372<

so, I configured a second monitor at home.

At first there was no problem. But, then I changed the primary monitor and moved the mouse to the "negative" screen. 

Then, as shown below, the x value counted "upward" toward the right and toward zero. 
?is this as expected? why? 
And, is MouseMove causing the move? or does the MouseGetPos return the wrong value for x?

x  >-723<   y>188<
x  >-722<   y>188<
x  >-721<   y>188<
x  >-720<   y>188<
x  >-719<   y>188<
x  >-718<   y>188<
x  >-717<   y>188<
x  >-716<   y>188<
x  >-715<   y>188<
x  >-714<   y>188<
x  >-713<   y>188<
x  >-712<   y>188<
x  >-711<   y>188<

I'm going to try to see if the effect continues once x becomes a positive integer...

and here we have the problem stopping as soon as we reach zero...

x  >-4<   y>386<
x  >-3<   y>386<
x  >-2<   y>386<
x  >-1<   y>386<
x  >0<   y>386<

Is there something I'm missing or would someone help me open a ticket on this?

I had that same question.

How can we tell if the mouse is moving or if MouseGetPos is off by one?

That was easier to test than to ask the question. I commented out the MouseMove and the pointer stopped moving. With the mouse move in the mouse would move right by one pixel every loop. It stopped moving when it hit positive 8 on my computer.

here's a version with several MouseMoves - 

Local $x = MouseGetPos(0)
Local $y = MouseGetPos(1)

While(True)
    MouseMove($x,$y,0)
    MouseMove($x,$y,0)
    MouseMove($x,$y,0)
    MouseMove($x,$y,0)
    MouseMove($x,$y,0)
    MouseMove($x,$y,0)
    MouseMove($x,$y,0)
    MouseMove($x,$y,0)
    MouseMove($x,$y,0)
    MouseMove($x,$y,0)
    MouseMove($x,$y,0)
    MouseMove($x,$y,0)
    MouseMove($x,$y,0)

    Sleep (1500) ;(3*60*100) ; sleep 3 minutes

    $x = MouseGetPos(0)
    $y = MouseGetPos(1)

    Consolewrite(@CR & "x  >" & $x & "<   y>" & $y & "<")

WEnd


x  >-3660<   y>201<
x  >-3659<   y>201<
x  >-3658<   y>201<
x  >-3657<   y>201<
x  >-3656<   y>201<
x  >-3655<   y>201<

 

The $x position only moves by one pixel per loop.
If MouseMove were the culprit, wouldn't we see $x move once for each MouseMove?

To me, this implicates the MouseGetPos code.

Here is a variation with two sets of MouseGetPos within the loop and only One MouseMove.

Local $x = MouseGetPos(0)
Local $y = MouseGetPos(1)

While(True)

    MouseMove($x,$y,0)

    Sleep (1500) ;(3*60*100) ; sleep 3 minutes

    $x = MouseGetPos(0)
    $y = MouseGetPos(1)

    $x = MouseGetPos(0)
    $y = MouseGetPos(1)

Consolewrite(@CR & "x  >" & $x & "<   y>" & $y & "<")

WEnd

the "drift" is only 1 pixel per loop.

x  >-3711<   y>339<
x  >-3710<   y>339<
x  >-3709<   y>339<
x  >-3708<   y>339<
x  >-3707<   y>339<

I was only trying to point out that the MouseGetPos numbers never changed without MouseMove, so MouseGetPos is getting the right numbers, but MouseMove is moving the mouse to the wrong place.

Having multiple MouseMoves and only one MouseGetPos won't change that, the $x value is going to always be the same so it just moves it to the wrong spot multiple times, always in the same spot.

I agree that the error is most likely in MouseMove - but, it poses an interesting chicken and egg type problem. 
The movement doesn't happen without both functions being used.
It seems sort of like a relativity thought experiment. 
Which is the frame of reference?

Is there anyone with access to the code who can settle this? 
I'm guessing that the negative numbers imply a failure to account for zero when repositioning. 
But, the code will know in the end.

 

adding a couple of lines to the code makes an adequate "UDF" 


    If $x < 0 Then $x = $x - 1
    If $y < 0 Then $y = $y - 1

Could someone help me open the ticket?

I don't think it has anything to do with MouseGetPos at all, MouseGetPos seems to be working fine. The problem is that MouseMove is moving to the wrong spot, so when you use MouseGetPos, it's reading the spot the pointer is actually at, which is one pixel to the right of where it should be, so every time you move the mouse it moves right one more position because MouseMove put it there, and not because MouseGetPos did anything.

that does seem most likely, but, suppose that MouseGetPos is returing a value that is one greater than the actual mouse position when the mouse position is less than zero? Wouldn't that yield results that would look the same from the observer's point of view?

Move your mouse to the upper left corner of your screen, MouseGetPos will read 0,0. Move it to the upper left corner of your second screen and do the same, it should read the X dimension of that screen's resolution (negative of course). My screens are set to 1920x1200, so when I move the mouse to the upper left corner of the second screen I get -1920 for $x.

But, shouldn't you get -1919? where is pixel ZERO?
The second "negative screen" should have a range off -1919 to 0 - that is 1920 pixels...

This is a good test, but, I interpret it to mean that the problem is in MouseGetPos....
