Q3Vector2D_Set

You can use the Q3Vector2D_Set function to set the scalar components of a two-dimensional vector.

TQ3Vector2D *Q3Vector2D_Set (
TQ3Vector2D *vector2D, 
float x, 
float y);

vector2D

A two-dimensional vector.

x

The x scalar component of the vector.

y

The y scalar component of the vector.

DESCRIPTION

The Q3Vector2D_Set function returns, as its function result and in the vector2D parameter, the two-dimensional vector whose scalar components are specified by the x and y parameters.
