# Unigine::Math::hvec2 Struct

This class represents a vector of 2 half (16-bit float) components.

## hvec2 ( ) #

Default constructor. Produces a zero vector.

## hvec2 ( const hvec2& v ) #

Constructor. Initializes the vector by copying a given source vector.

### Arguments

• const hvec2& v - Source vector.

## hvec2 ( half x, half y ) #

Constructor. Initializes the vector using given half values.

### Arguments

• half x - X component of the vector.
• half y - Y component of the vector.

### Examples

Source code (UnigineScript)
``````hvec2(2.0, 3.0);
/*
Creates a vector (2.0, 3.0)
*/``````

## hvec2 ( half v ) #

Constructor. Initializes the vector using a given scalar value: x=v, y=v.

### Arguments

• half v - Scalar value.

## hvec2 ( float v ) #

Constructor. Initializes the vector using a given scalar value: x=v, y=v.

### Arguments

• float v - Scalar value.

## hvec2 ( const vec2& v ) #

Constructor. Initializes the vector using a given vec2 source vector.

### Arguments

• const vec2& v - Source vector.

## hvec2 ( const dvec2& v ) #

Constructor. Initializes the vector using a given dvec2 vector.

### Arguments

• const dvec2& v - Vector.

## const half *operator const Unigine::Math::half * ( ) const#

Performs type conversion to const half *.

## const void *operator const void * ( ) const#

Performs type conversion to const void *.

## half *operator Unigine::Math::half * ( ) #

## hvec2 &operator= ( const hvec2& v ) #

Performs vector assignment. Destination vector = Source vector.

### Arguments

• const hvec2& v - Source vector.

Result.

## half &operator[] ( int i ) #
