Members
vec2 ( ) #
Default constructor. Produces a zero vector.vec2 ( vec2 v ) #
Constructor. Initializes the vector by copying a given source vector.Arguments
- vec2 v - Source vector.
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 ( vec3 v ) #
Constructor. Initializes the vector using a given three-component vec3 source vector: x=v.x, y=v.y.Arguments
- vec3 v - Three-component source vector.
explicit vec2 ( vec4 v ) #
Constructor. Initializes the vector using a given four-component vec4 source vector: x=v.x, y=v.y.Arguments
- vec4 v - Four-component source vector.
explicit vec2 ( dvec2 v ) #
Constructor. Initializes the vector using a given dvec2 source vector.Arguments
