Okay here's how I would devise it in VB.NET, you can do it by creating a device context to the screen, but I prefer this method as you have less extern API calls.
[highlight=vb.net]
Import System.Runtime.InteropServices
'...
<DllImport("user32.dll")> _
Public Shared Sub mouse_event(ByVal dwFlags As UInt32, ByVal dx As UInt32, ByVal dy As UInt32, ByVal dwData As UInt32, ByVal dwExtraInfo As UIntPtr)
End Sub
Public Sub TryClick(ByVal clickPosition As Point, ByVal checkPositions As Point(), ByVal col As Color)
If ReadyToClick(checkPositions, col) Then 'make sure the positions hold the color.
Dim dx As Int32 = clickPosition.X * 65535 / Screen.PrimaryScreen.Bounds.Width 'calculate the absolute position of the x-axis
Dim dy As Int32 = clickPosition.Y * 65535 / Screen.PrimaryScreen.Bounds.Width ' " " " y-axis
mouse_event(&H8000 Or &H1 Or &H2 Or &H4, dx, dy, 0, UIntPtr.Zero) 'move the mouse to an absolute position and click.
End If
End Sub
Private Function CaptureScreen() As Bitmap
Dim screenSize As Size = Screen.PrimaryScreen.Bounds.Size 'calculate the size of the screen
Dim bmp As New Bitmap(screenSize.Width, screenSize.Height) 'make a buffer bitmap to hold the screen data
Using g As Graphics = Graphics.FromImage(bmp) 'create a graphics object to link to our bitmap
g.CopyFromScreen(Point.Empty, Point.Empty, screenSize) 'copy the screen data into the bitmap.
End Using
Return bmp
End Function
Private Function ReadyToClick(ByVal pts As Point(), ByVal c As Color) As Boolean
Dim screen As Bitmap = CaptureScreen()
For Each pt As Point In pts
If Not screen.GetPixel(pt.X, pt.Y) = c Then Return False 'if the color are the current point <> the correct color exit immediately
Next
Return True
End Function
[/highlight]
Now to use this I'd do something like the following:
[highlight=vb.net]
Private CheckPoints As Point() = New Point() {New Point(550, 609), _
New Point(550, 583), _
New Point(550, 556), _
New Point(550, 554), _
New Point(550, 500), _
New Point(550, 474), _
New Point(550, 449), _
New Point(550, 423), _
New Point(550, 393), _
New Point(550, 368), _
New Point(550, 339), _
New Point(550, 313), _
New Point(550, 287), _
New Point(550, 258)} 'array of points to look for the color at.
Private CheckColor As Color = Color.FromArgb(177, 11, 60) 'color to check for (in RBG)
Private ClickPosition As New Point(637, 690) 'position to click at when it's ready to do so
'...some method
TryClick(Me.ClickPosition, Me.CheckPoints, Me.CheckColor)
'...end method
[/highlight]
Enjoy.
