Press space to toggle mode. Up and down move in ρ (rho) by ten (up increases, down decreases) in mode 0, Left and right move in θ (theta) by ten degrees (right decreases, left increases) in mode 1, theta constantly changes by ten, with left and right changing the sign of this change.
In the Polar plane, ρ represents distance from the pole (origin), and θ represents degrees in standard position (0 is straight right, 90 is straight up, 180 is straight left, 270 is straight down) The pair is always given in the order (ρ, θ) This project was intended as a tech demo to polar coordinates on Scratch, the custom block and a couple variables is all you need to use this in your project.
