MouseMove Deceleration

[Stompa]

I'm trying to simulate some mouse movement using MouseMove(). However, I'm finding that when approaching the destination coord the mouse pointer slowly decelerates - but I want it to move at a constant speed.

I'm unclear whether MouseMove() is coded entirely in AutoIt, or whether it's simply calling some underlying Windows API function. Either way, could it be that it's the mouse settings on my PC that are causing the deceleration?

I've tried disabling acceleration by moving my Mouse Speed slide bar all the way to the left as suggested here:

and also disabling 'Enhance pointer precision', and my feeling is it does make some improvement, but there's still some deceleration occuring.

Any ideas?

Thanks

Let's see your code.

...MouseMove()...I want it to move at a constant speed...

try: http://www.autoitscript.com/forum/index.ph...st&p=249007 I've not tested it.

Let's see your code.

The code is trivial, something as simple as:

MouseMove(100,100)

MouseMove(800,800,50)

will show the problem.

Yes, I see what you mean. But if you set the speed to 0 the move is instant. Do you want to move at a constant speed so that the cursor is visible? In this case could you try having a for next loop moving the mouse along the path a bit at a time with the speed set to 0, like this

MouseMove(100,100)
for $n = 100 to 800 Step 5
    MouseMove($n,$n,0)
    sleep(10)
Next

Thanks, that's pretty much what I ended up doing, though because I'm actually using arbitrary points I just use Pythagoras to calculate the number of steps required. Unfortunately, I also have to omit the sleep(), since even using sleep(1) slows things down a great deal.
