happy pi day from @Gusay10 (note december 13, 2025) ok so i know why the functions seem to teleport 180degrees. vertical angles are congruent, which means 180deg=0deg. how to use: - drag the blue dot project notes: - trigonometry functions (sin, cos, tan, atan) provided by scratch are degrees as input instead of radians - tan is more of like finding the slope rather than the actual implementation of tan provided by scratch math fun fact #1: tan is the angle turned into a line slope; if the angle is vertical, you will get a slope of undefined (think of a wall as tall as you think). math fun fact #2: atan is the (programming function name of an) inverse function of tan, turning the slope of a line to an angle. this is useful if you want your entities to face towards something in a 2d plane, though point-to-point slope must be calculated first.
