UNIGINE_DECLARE_USE_MEMORY UNIGINE_INLINE vec2 ()

Default constructor that produces a zero vector.

UNIGINE_INLINE vec2 (const vec2 & v)

Initialization by a vector.

Arguments

• const vec2 & v - The value of the vector.

UNIGINE_INLINE vec2 (float x, float y)

Initialization by scalars.

Arguments

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

explicit UNIGINE_INLINE vec2 (float v)

Initialization by a scalar: x=v, y=v.

Arguments

• float v - The value of the vector.

explicit UNIGINE_INLINE vec2 (const vec3 & v)

Initialization by a four component vector: x=v.x, y=v.y.

Arguments
