Vector2

Vector2

Variables

Variable	Description
float &x	reference to the first element of pos[]. can be used as myVector2.x.
float &y	reference to the second element of pos[]. can be used as myVector2.y.

public methods

Function	Description
float Magnitude()	returns non sqr magnitude of current Vector2
float sqrMagnitude()	returns sqr magnitude of current Vector2
void Normalize()	normalizes current Vector2
Vector2 normalized	returns the normalized version of current Vector2

static variables

Variable	x	y
Vector2 up	0	1
Vector2 down	0	-1
Vector2 left	-1	0
Vector2 right	1	0
Vector2 zero	0	0

use these to quickly obtain a "vector" in a given direction, or a Vector2 filled with 0

static methods

Function	Description
float fastDistance(Vector2 a, Vector2 b)	returns the distance between a and b in a tiled space ( like chess )
float Distance(Vector2 a, Vector2 b)	returns the exact distance between a and b
float Dot(Vector2 a, Vector2 b)	returns the dot product of a and b
Vector2 Lerp(Vector2 a, Vector2 b)	returns the middle point between a and b, equivalent to glsl mix(a, b, 0.5) or cg lerp(a, b, 0.5)
Vector2 Lerp(Vector2 a, Vector2 b, float c)	returns the point c between a and b, equivalent to glsl mix(a, b, c) or cg lerp(a, b, c)
Vector2 Slerp(Vector2 a, Vector2 b, float c)	smooth interpolation between a and b given c.

constructors

Vector2(float x, float y)	generates a Vector2 containing the values x and y.
Vector2()	generates a Vector2 containing the values 0 and 0.

operators

operator+ adds two Vector2s

operator- substracts two Vector2s

operator+= adds the values of Vector2 to current

operator-= substracts the values of Vector2 from current

operator* multiplies current Vector2 by a float

operator/ divides current Vector2 by a float

operator+ adds float to every value of current Vector2

operator- substracts float from every value of current Vector2

operator*= multiplies every value of current Vector2 by float

operator/= divides every value of current Vector2 by float

operator== returns true if two Vector2s are equal and false if they are different
