Help w/ bot function

[Fenryr]

i'm new to C#, and despite my best efforts to search the internet, i can't seem to find anything similar to auto-it's "pixelsearch" function in C#.

What i'm basically trying to do is to have the program search the screen to find all pixels that are a certain color, and then output the coordinates of those pixels so that i can click on them.

So far, all i can think of is to take a screenshot, and search that, but that seems far too complicated and slow.

Also if someone could point me in the right direction about making some sort of system that woiuld allow for color tolerance(find similar colors, not just the exact color i provide) any help would be greatly appreciated.

I have another question, i know vb .net pretty well, so would it be bad practice to use the information from C Sharp syntax - Wikipedia, the free encyclopedia and learn c# through trial and error, or should i read some tutorials / books?

This is a really good C# book, easy to learn from.
Check out his other books aswell.

I assume that's exactly what AutoIt does behind the scene

Actually AutoIt contains a com controll that you can include in your project.

Simply add this dll file to your project and you should be able to use AutoIt's features

If you have autoit installed you can find the dll in WhereEverYouInstalledIt\AutoItX\AutoItX3.dll

I wrote my very first fishbot with that com reference, it's a good start

Isn't there a P/Invoke that you can call to read a windows pixels? I'm pretty sure there is...

BAM! I'd write a wrapper for GetPixel so it reads ~every two pixels(depending on your resolution) and returns an array of Points. Use GetDC and ReleaseDC + FindWindow to grab the window DC/handle. This would be faster than using AutoITs library. I'm almost positive.

I just copy/pasted this from my vb.net code but there's nothing that's hard to conver to C#..i would, but....

Declare Function GetPixel Lib "gdi32" (ByVal hDC As Integer, ByVal x As Integer, ByVal y As Integer) As Integer
Declare Function GetDesktopWindow Lib "user32" () As Long
Declare Function GetWindowDC Lib "user32" (ByVal hWnd As IntPtr) As IntPtr
Declare Function ReleaseDC Lib "user32.dll" (ByVal hWnd As IntPtr, ByVal hDC As IntPtr) As Integer


Public Function GetPixColor(ByVal x As Int32, ByVal y As Int32) As Short()
Dim hWnd As IntPtr = 0
Dim hDC As IntPtr
hWnd = GetDesktopWindow()

hDC = GetWindowDC(hWnd)

Dim lColor As Int32 = GetPixel(hDC, x, y)
ReleaseDC(hWnd, hDC)
'' convert to rgb
Dim rgbs(2) As Short

rgbs(0) = ColorTranslator.FromWin32(lColor).R
rgbs(1) = ColorTranslator.FromWin32(lColor).G
rgbs(2) = ColorTranslator.FromWin32(lColor).B
Return rgbs
End Function

Later down the road you will need
Public Declare Sub mouse_event Lib "user32.dll" (ByVal dwflags As Integer, ByVal dx As Integer, ByVal dy As Integer, ByVal dwData As Integer, ByVal dwExtraInfo As Integer)
Public Declare Function SetCursorPos Lib "user32.dll" (ByVal X As Int32, ByVal Y As Int32) As Boolean


Public Enum MouseFlags As UInt32

LEFTDOWN = &H2
LEFTUP = &H4
MIDDLEDOWN = &H20
MIDDLEUP = &H40
MOVE = &H1
ABSOLUTE = &H8000
RIGHTDOWN = &H8
RIGHTUP = &H10
End Enum

Good luck.
