Vector2 Class

A class representing a two-dimensional vector.

Class Definition

class Vector2 {
    public float x, y;

    public void Add(Vector2 v)
    public Vector2 AddNew(Vector2 v)
    public void Sub(Vector2 v)
    public Vector2 SubNew(Vector2 v)
    public float Distance(Vector2 v)
    public Vector2 GetNormalize()
}

Usage Example

Vector2 vec = new Vector2();
vec.x = 0.0f;
vec.y = 1.0f;

// Same as above
Vector2 vec2 = makeVector2(0.0f, 1.0f);

Vector2 Utility Functions

makeVector2

Vector2 makeVector2(float x, float y)

Global function. Returns a Vector2 initialized with the specified x, y components.

makeVector2Add

Vector2 makeVector2Add(Vector2 vec1, Vector2 vec2)

Global function. Adds vectors together and returns the result as a new Vector2.

makeVector2Sub

Vector2 makeVector2Sub(Vector2 vec1, Vector2 vec2)

Global function. Subtracts vec2 from vec1 and returns the result as a new Vector2.

Constructors

Vector2()

public Vector2()

Creates a Vector2 with x, y components set to 0.

Vector2(float)

public Vector2(float s)

Creates a Vector2 with x, y components initialized to s.

Vector2(float, float)

public Vector2(float x, float y)

Creates a Vector2 with the specified x, y components.

Methods

Add

public void Add(Vector2 v)

Adds the vector v specified in the argument to this instance.

AddNew

public Vector2 AddNew(Vector2 v)

Adds the vector v specified in the argument to this instance and returns the result as a new Vector2.

Sub

public void Sub(Vector2 v)

Subtracts the vector v specified in the argument from this instance.

SubNew

public Vector2 SubNew(Vector2 v)

Subtracts the vector v specified in the argument from this instance and returns the result as a new Vector2.

Distance

public float Distance(Vector2 v)

Returns the distance to the vector v specified in the argument.

GetNormalize

public Vector2 GetNormalize()

Normalizes the vector and returns the result as a new Vector2.
