public class Vector2f
extends Tuple2f
A 2 element vector that is represented by single precision floating point x,y coordinates.

Constructor Index

o Vector2f()
Constructs and initializes a Vector2f to (0,0).
o Vector2f(float, float)
Constructs and initializes a Vector2f from the specified xy coordinates.
o Vector2f(float[])
Constructs and initializes a Vector2f from the specified array.
o Vector2f(Vector2f)
Constructs and initializes a Vector2f from the specified Vector2f.

Method Index

o angle(Vector2f)
