The vector3 class represents a three-dimensional vector.
Methods
create
This is default constructor for the Vector3 class and returns a Vector3 object.
Syntax
vector3 Vector3 ( float x = 0, float y = 0, float z = 0 )
- x, y and z: coordinates for the vector. If not specified, they default to 0.
- Instead of these three coordinates, a single Vector3 object may be inserted to clone it.
Example
This example sorts all players in a nice line on the center of the map.
