Code and "art" by me (@kriblo), instructions are further down. This is far less serious than the title might indicate ;) Concept: Wireless Scratch Protocol using Video Sensing This project is intended to test and demonstrate the potential for two Scratch projects to communicate, by implementing a Video Sensing based interface, and then running the two projects on two facing laptops. This might be used to match two chess engines, as discussed here: https://scratch.mit.edu/studios/25643089/comments/#comments-76324686 ========Instructions=========== In my testing, this is what I did: Run this project in full screen on two laptops facing each other. Place each laptop so that each camera image of the other is fairly centered. If you don't have access to a second computer, you can use a mirror ;) The Receiver sprite (the arrow) should turn to point in the direction the colors run in the Sender sprite on the other computer. If it doesn't work, you can try these steps: - Make sure the ambient lighting is medium, not too bright or too dark. - Click and drag to reposition the Receiver so it is in the part of the screen where the camera image is showing the other computer's Sender. - It might be easier to set things up if you temporarily pause the Sender by pressing P, or turn off video by pressing V, press again to start again. - You might need to flip the video, by pressing F.
