Answer 1

Why is everyone complicating this?

The only problem is Math.atan2( x , y)

The corret answer is Math.atan2( y, x)

All they did was mix the variable order for Atan2 causing it to reverse the degree of rotation.

All you had to do was look up the syntax https://www.google.com/amp/s/www.geeksforgeeks.org/java-lang-math-atan2-java/amp/
