vec2d

Description
Represents a 2-dimensional vector object consisting of two floating-point values (x, y).
vec2d provides arithmetic operators, value assignment, printing and resetting, as well as several vector-specific script methods like normalization, length calculation and null-vector checking.

An vec2d is typically created and manipulated inside scripts when 2D positions, offsets or directions are required.

Methods
void normalize()
Normalizes the vector so that its length becomes 1 (unit vector).
If the vector is a null vector, no change is applied.

float length()
Returns the floating-point vector length calculated as sqrt(x*x + y*x).

bool isNull()
Checks whether the vector is a null vector (x = 0 and y = 0).
Returns true if the vector is zero-length.

void set(float x, float y)
Assigns new floating-point values to the vector.
Example: v.set(10.0, 5.0);

Operators
vec2d supports the operators +, - and * with another vector, returning a new vec2d.

Example
void main()
{
    vec2d v(3.0, 4.0);
    float len = v.length();
    Print("Length: " + len);
    
    v.normalize();
    Print("Normalized vector length: " + v.length());
    
    bool isZero = v.isNull();
    Print("Is Null Vector: " + isZero);
    
    v.set(10.0, 5.0);
    Print("Vector set to ");
    Print(v);
