Need help searching for multiple points

[Justchris25]

Alright, this will kind of be a lengthy question but basically I'm trying to search for a top point of an arrow. regardless of which way the arrow is facing and move the mouse to it. This is just for fun with no real purpose except learning.

I'm doing this in mspaint so the search area is not very big. Using lines I draw an arrow.

The arrow has a tip 2 sides and then the bottom. I know the distance between the top to each side, and the top to the bottom.

Right now it takes way to long to search because each point is using a for loop. And its also not finding the arrow tip.

Heres an example of my code. Any help would be awesome

this is just mock code. Id have to completely re-write my code to post which I wouldnt mind doing if someone was willing to help. But for now this is just an idea.

for $sAreaX = 60 to 500 ;sets search area x, y

for $sAreaY = 60 to 500

$point1 = pixelgetcolor($sAreaX, $sAreaY) ;searches for the first black point

if $point1 = 0x00000 then ;

for $x2 = $sAreaX - $lineLength to $sAreaX + $lineLength

for $y2 = sAreaY - $lineLength to sAreaY + $lineLength

$point2 = pixelgetcolor($x2, $y2)

if $point2 = 0x00000 and _lineLength(sAreaX, sAreaY, $x2, $y2)= _ = $orginalLength then

and so on... for each of the 4 points.

So it takes forever and essentially doesnt work. Sorry if thats confusing. Any help would be awesome.

In the 4 years you been here, did you hear about pixelsearch?

EDIT:

Sorry, that was a bit of a lousey answer that.

Think about using pixel search to find the first black = you have a top area to work with

reverse the search to find the bottom.

Since you know how big your arrow is, with some math you can roughly determine its left and right

You now have a smaller area to begin finding your point.

That was what I was originally trying to do.. But then switched to getcolor. Thanks for the input though. I'll go back and reattempt it.

[JohnOne]

how many directions does your arrow point?

If its lefr right up down, you might want to localize your area using pixelsearch and search it for the 4 possible checksums you might have.

Well this doesn't seem to be working either. Here's what I've got so far..

Any help would be awesome.
