Where did you get the pictures from? Did you capture them yourself or is there a site that has them all nicely done? I might add to it so it picks up certain gear. <-- Nevermind. I did it myself and it worked for picking up other objects.
Question: I don't know much about about coding. Does your script look on the entire screen or foreground, or just in the 1st box? I'm wondering if I could make it more efficient by just looking in the small box that the object could be in.
