vec2 [object]

• methods
  • rotate - return vector, rotated by specified angle
• read-only properties
  • [real] length
  • [real] length_squared
  • [vec2] normalized - return a vector with length = 1 if possible, length = 0 if too short
  • [vec2] perp - returns vec2(-y,x) - 90 degree clockwise vector
  • [vec2] perp2 - returns vec2(y,-x) - 90 degree counter-clockwise vector
  • [int] size - returns 2 - the number of components in this vector
• read/write properties
  • [real] x
  • [real] y
  • [real] angle
• overloaded operators
  • + - adds two vec2/real values
  • - - subtracts two vec2/real values
  • * - multiplies two vec2/real values
  • / - divides two vec2/real values
  • % - returns modulo of two vec2/real values
  • comparison between vec2 values: first by X, then by Y
  • unary - - returns negated vec2
• other features:
  • cloning support
  • serialization support
  • GC-safe
  • indexing support for indices 0 - 1: returns/sets the specified subvalue
  • tostring, dump = "vec2(<x>;<y>)"
