First post on the boards. I've read everything that popped up through search relating to what I am trying to do and no luck. What I am trying to do is use pixel detection to lock on to the pixel that I am currently hovering over. In other words I am trying to search a small box in the middle of my screen instead of my entire window. This should stay locked until I release the key. Here is the part giving me trouble:

~F3::
MouseGetPos, begin_x, begin_y
while GetKeyState("F3")
{
MouseGetPos, x1, y1
PixelSearch, Px, Py, 0, 0, 636, 638, %color%, 0, Fast
if ErrorLevel
MsgBox, That color was not found in the specified region.
else
MouseMove, Px, Py, 0 ;0 is mouse speed, 0 is instant
}
Return



I am new to the lang so go easy on me. Thanks in advance!

Can you give more info? Im a little puzzled in what your trying to do. You want to lock-on to a pixel? What do you mean by that?

Also use the MouseGetPos cords with the PixelSearch region if thats what your looking for.

Ok this is what I have done so far. It works but just not like I had hoped. I don't believe there is much more I can do to make it work with the apps that I am trying. But it is flawless when using it in paint.


F1::
{
IniFile := "C:\Users\Jesse\Desktop\location.txt"
FileGetSize, size, %IniFile%
if (size = "") {
MsgBox Setting up
IniWrite, %color%, %IniFile%, location, color
} else {
IniRead, %color%, %IniFile%, location, color
}
CoordMode, Pixel
Return
}

F2::
{
MouseGetPos, x, y
PixelGetColor,color, %x%, %y%
IniWrite, %color%, %IniFile%, location, color
Return
}

~F3::
MouseGetPos, begin_x, begin_y
while GetKeyState("F3")
{
MouseGetPos, x1, y1
PixelSearch, Px, Py, 803, 524, 803, 524, %color%, 0, Fast
MouseMove, Px, Py, 0 ;0 is mouse speed, 0 is instant
}
Return



f1: creates ini file if there isn't one.
f2: selects the pixel to lock to.
Hold f3: goes to the pixel and stays on it until you let off.

I was hoping to use it in some simple flash games etc. as a means of aiming. It was a good beginner project but I just don't think PixelSearch can process it.

If you have any suggestions let me know.

Theres much better way to do stuff like this. First i wouldnt use GetKeyState.

You know there is also a PixelMatrixSearch right? Search the forum.

Basically it searchs or obtains a 3x3 matrix be default.. Meaning. a combination of 3x3 pixels so its uniqe. That way it wont mis-match as much.. or maybe not at all

PixelMatrixSearch seems to be pretty advanced from the examples posted on here. I'll read up on it tommorow and modify/test it. Thanks for the support, i'll keep posting here with the changes I make.

It actually isnt complicated at all. 2 functions. One finds the matrix. One obtains the matrix. Just call them when you need to.

I have made the changes and implemented PixelMatrixSearch. Seems to work on a screen cap of the game but not in the game itself?

Here is what I've got:


#NoEnv
#SingleInstance Force
#Persistent
SetBatchLines -1
SetDefaultMouseSpeed, 0
SetControlDelay, -1
Process,priority,,low

SetBatchLines, -1
CoordMode, Pixel, Screen
CoordMode, Mouse, Screen

f1::
MouseGetPos, mX, mY
SplashImage, Off
Matrix := GetMatrix(mX,mY,4)
Matrixtemp := Matrix
again:
soundbeep 3000
Result := FindMatrix(1,1600,1,1200,4,Matrix)


~f2::
MouseGetPos, begin_x, begin_y
while GetKeyState("f2")
{
Result := FindMatrix(1,1600,1,1200,4,Matrix)
StringSplit, Result, Result, %A_Space%
Mousemove, %Result1%, %Result2%
}
Return

f3:: reload


Once again, I am open to any suggestions. Thanks.
