I made this for my class project on "Ideas of new inventions using this around you.". And I so happened to own a computer, and a Scratch account. So, I made this, a horrifyingly decently accurate tracker prototype that tracks the y and x axis of a subject by using variables to see where exactly your subject is on the quadrant plane. CONTROLS- WASD to move the red point.
WARNING: This has a bug where if you press a key when your red point is on the edge of the border, the radar counts it as one point up, so don't try to go through the border, or it will mess up the radar.
