▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ ★ Instructions ★ ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ ★ press space key to switch costumes between arrow and point ★ This project is a functional Coordinate Geometry Engine built entirely from scratch. It utilizes the classic high school analytical geometry formula for the rotation of axes: 1.) x' = x*cos(θ) + y*sin(θ) 2.) y' = -x*sin(θ) + y*cos(θ) ★ where: x = x-position of object in normal cartesian plane y = y-position of object in normal cartesian plane x' = x-position of object in rotated cartesian plane y' = y-position of object in rotated cartesian plane θ = angle of rotation with x-axis (anti-clockwise) ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ ★ Notes ★ ★ Credit me if you use it in your projects (if you do, pls show me, I'd love to see how you use it!) ★ My next project will have an application of this! ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ ★ Credits ★ ★ Scratch for the arrow sprite ★ rest by me ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ tags:- (ignore) #cartesian #coordinate-system ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
