Answer 1

I don't really get your question, since you kind of already made it in the fifth line. You could use a function like this (If you would use classes, please use classes, classes are very good, I promise):

corner(i) {
return [this.x + cos(i * this.angle) * this.r, this.y + sin(i * this.angle) * this.r];
}

(I didn't look at your code that much, but it basically returns an array of the x and y position of the angle, please look at it, don't just copy and paste it it probably wouldn't work)

Answer 2

I get what you are saying. Thanks for the reply. I used to use classes but I they take ages to build (especially with a lot of them) and they reduce readability. I use constructor functions.

I implemented what you did without the use of classes. Thanks for the help. Trigonmetry brings out the worst of my ability!
