vec2 Class
Members
vec2()
Default constructor. Produces a zero vector.vec2(const vec2 & v)
Constructor. Initializes the vector by copying a given source vector.Arguments

vec2(float x, float y)
Constructor. Initializes the vector using given float values.Arguments
- float x - X component of the vector.
- float y - Y component of the vector.
Examples
Source code (UnigineScript)
vec2(2.0, 3.0);
/*
Creates a vector (2.0, 3.0)
*/explicit vec2(float v)
Constructor. Initializes the vector using a given scalar value: x=v, y=v.Arguments
- float v - Scalar value.
Examples
Source code (UnigineScript)
vec2(1.0);
/*
Creates a vector (1.0, 1.0)
*/explicit vec2(const vec3 & v)
Constructor. Initializes the vector using a given three-component vec3 source vector: x=v.x, y=v.y.Arguments
- const vec3 & v - Three-component source vector.
explicit vec2(const vec4 & v)
Constructor. Initializes the vector using a given four-component vec4 source vector: x=v.x, y=v.y.Arguments
- const vec4 & v - Four-component source vector.
explicit vec2(const dvec2 & v)
Constructor. Initializes the vector using a given dvec2 source vector.Arguments
- const dvec2 & v - Source vector.
explicit vec2(const ivec2 & v)
Constructor. Initializes the vector using a given ivec2 source vector.Arguments
- const ivec2 & v - Source vector.
explicit vec2(const float * v)
Constructor. Initializes the vector using a given pointer to the array of float elements: x=v[0], y=v[1].Arguments
- const float * v - Pointer to the array of float elements.
void set(float x_, float y_)
Sets the vector by components.Arguments
