Help!

[SooperNoobCroo]

Okay you guys, I need some help. Attached is some software that moves a gun aroud and fires it at a IR point. Is there a way that in stead of moving a couple of servos, can it move the mouse to those coordinates? And click? That would rule. Ill send you guys pics when it's done.

What exactly do you want to achieve?

Is this a robotics question?

Is this a robotics question?

Um, yes. It is. I didn't know there was a section on that. But what I'm trying to do is identify a white dot and put the mouse there.

Ok, if you are attempting to make a simulation of this I can help you.

Get the picture of "what the robot sees" in a picture box and make a function that loops round all the pixels in the box to find any white ones.

I take it that you know how to use loops, there is an API call known as GetPixel which returns the colour of the pixel at specified coordinates.

It looks somewhat like this:

Private Declare Function GetPixel Lib "GDI32" (ByVal hDC As Long, ByVal x As Long, ByVal y As Long) As Long

Obviously as soon as your program finds a white pixel then it will know where the white target is.

GetPixel is extremely slow. Depending on your needs, you may want to use Get/SetDIBits, or even consider switching to C++ and using something like SDL.

it sounds to me like classroom work in which case it has to be vb and speed doesnt matter. is this the case?
