Game Triangular Pixel Search

[DodgeThis]

PixelSearch Function searches only in rectangular area , right ? Please forgive my noobism as an effort to learn more. But is there a way i can use Same function to search Triangular area.

So please help me with these:

1) While using AutoIt Window Info is it advisable to keep it set for screen or client window while using it for game?

2) In context to above , since i want to use it for triangular search is it possible?

3) What would be the fastest way to scan an image for certain color (any special algorithm to use ? fast in sense of CPU Time and efficiency.)

4) I believe searching very small rectangle areas spread over the entire screen. Would this make it slower.

I do apolize if i am sounding absurd. This is not an idea i have so far been succesful only with the rectangular search, but at cost of CPU Overheat.

Any help appreciated

Here what i am trying to do:

No, not with PixelSearch(), but you could code a function of your own. Just take in three sets of coordinates instead of two and do the maths to generate a loop for PixelGetColor(). You could make a fuction to search an oval or a pentagon. Anything for which you can do the maths to find a set of x/y coordinates contained in the shape.

Probably window vice desktop, especially if not running full-screen.

Answered above.

a. Search the smallest possible area that will provide usefull results.

b. Don't search every pixel. If the target is a square 10 pixels on a side, then searching every ninth or tenth pixel will find it.

It will if you still cover the whole screen. But this is testable. Code a search both ways and time it with TimerInit()/TimerDiff().

I hope you meant overhead. Nothing about an AutoIT script will cause overheating in a normally functioning computer.

Aight thanks for replying.

I was thinking more like make small rectangles. Keep each as a separte Switch Case(with minimum result needed for matching). Once found jump to executing that part of code.

One more quick question:

How does pixelsearch work ?

Diagonally Horizontally or just equationally (x1 + x2 )/2 , in context of rectangle

Left-to-Right, and Top-to-Bottom. The equivelent function is:

Func _SearchPattern($X1, $Y1, $X2, $Y2)
     Local $x, $y, $Color
     For $x = $X1 To $X2
          For $y = $Y1 To $Y2
               $Color = PixelGetColor($x, $y)
               ; Compare logic goes here...
          Next
     Next
EndFunc

Once again thank you.
