CODE EXAMPLE FOR CSHARP

vector3 unity

- Vector is a mathematical concept that holds both magnitude and direction.
Vector3.right /* (1, 0, 0) */   
Vector2.right /* (1, 0) */
Vector3.left /* (-1, 0, 0) */   
Vector2.left /* (-1, 0) */
Vector3.up /* (0, 1, 0) */      
Vector2.up /* (0, 1) */
Vector3.down /* (0, -1, 0) */   
Vector2.down /* (0, -1) */
Vector3.forward /* (0, 0, 1) */
Vector3.back /* (0, 0, -1) */
Vector3.zero /* (0, 0, 0) */    
Vector2.zero /* (0, 0) */
Vector3.one /* (1, 1, 1) */     
Vector2.one /* (1, 1) */
float length = myVector.magnitude /* Length of this Vector */
myVector.normalized /* Keeps direction, but reduces length to 1 */
