I'm not entirely sure if you are hung up on the syntax or the algorithmic part of this problem. I figure the syntax is simpler to look up so I will offer the simple calculation. Your tuple will be calculated using the lua math functions: math.rad, math.cos, math.sin {math.cos(math.rad(degrees)), math.sin(math.rad(degrees))}...

You could Add 180 and divide by 2 as @High Performance Mark suggests for your specific problem or here is a generalized version of it based on This post. This equation holds good for any limits I have written a simple function based on the equation: function [out] = normalizeLim(...

You can use the modulus operation. With integers this is the % operator, with floats you can use std::fmod // \brief Calculates the sum of two angles // \param[in] a First angle [degrees] // \param[in] b Second angle [degrees] // \return Sum of two angles [degrees, [0, 360)] double AddAngles(double...

const radiance:Number=180/Math.PI; angle=-(Math.atan2(mouseX-panel.x, mouseY-panel.y))*radiance; I used minus because usually the orientation is reverse when you don't add minus. hope this helps....
