Mouse speed

Blitz3D Forums/Blitz3D Programming/Mouse speed

In wich way can i modify the speed of the mouse under windows?
I tryied the program in the code archives, but its only read the current speed and doesn't set the new speed.

Const SPI_GETMOUSESPEED = 112
Const SPI_SETMOUSESPEED = 113
Const SPIF_SENDWININICHANGE = 2

Function GetMouseSpeed%()
Local TempSpeed%, Speed%

TempSpeed% = CreateBank(4)
api_SystemParametersInfo(SPI_GETMOUSESPEED, 0, TempSpeed%, 0)
Speed% = PeekInt(TempSpeed%, 0)

FreeBank TempSpeed%
Return Speed%
End Function

Function SetMouseSpeed(Speed%)
Local TempSpeed%, Flags%

TempSpeed% = CreateBank(4)
PokeInt TempSpeed%, 0, Speed%

Flags% = SPIF_SENDWININICHANGE
api_SystemParametersInfo(SPI_SETMOUSESPEED, 0, TempSpeed%, Flags)

FreeBank TempSpeed%
End Function

Print GetMouseSpeed()

waitkey()
SetMouseSpeed(4)
Print GetMouseSpeed()

If it's not a windowed program, it's easy to modify the speed just using code.

So, what should i do?

Well, you should obviously think about what you need to accomplish, then trawl through the 2D commandset and check the mouse related commands, then draw the logic on a piece of paper and then program it.

Failing that, you can use this. PageUP and PageDOWN changes the scale# variable and thus the speed of movement.

EDIT: I am worried though - This is really simple stuff and you don't even seem to be trying.

Graphics 640,480 

SetBuffer BackBuffer() 
scale#=1.0

Repeat 

xs=MouseXSpeed()*scale#
ys=MouseYSpeed()*scale#
MoveMouse 320,240  
x=x+xs  
y=y+ys 

If KeyHit(201) Then scale#=scale#-0.1 
If KeyHit(209) Then scale#=scale#+0.1 

Cls 
Text x,y,"X",True,True 
Text 10,10,"Scale: "+scale#
Flip 

Until KeyHit(1) 

End

Thanks, the program works, but in wich way can i set the windows option?
The modify should works when the user turn on windows, not when the user execute the program.

What windows option?

Well then, I misunderstood your question. I thought you couldn't do it in a B3D program.

Is possible using a windows dll(user32.dll, for example)?

I guess it's possible, maybe you find some information at www.msdn.com

I tryied the program in the code archives, but its only read the current speed and doesn't set the new speed.

I can't speak for the modified version you've posted above, but the version I posted works fine. The compiled DLL is even in there as well.

I guess my question would be why would you want to adjust windows parameters using Blitz?

I found the solution.
Thanks for the help.
I've another question, but i'll post a new topic.
