Matrix4x4.SetColumn

Description

Sets a column of the matrix.

You use this to build transformation matrices using right, up and forward vectors:

 // build a matrix from a transform.
    var matrix = Matrix4x4();

    /// Build a matrix from a transform.
    function Start () {
        matrix.SetColumn (0, transform.right);
        matrix.SetColumn (1, transform.up);
        matrix.SetColumn (2, transform.forward);
        var p = transform.position;
        matrix.SetColumn (3, Vector4 (p.x, p.y, p.z, 1));
    }

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    public Matrix4x4 matrix = new Matrix4x4();
    void Start() {
        matrix.SetColumn(0, transform.right);
        matrix.SetColumn(1, transform.up);
        matrix.SetColumn(2, transform.forward);
        Vector3 p = transform.position;
        matrix.SetColumn(3, new Vector4(p.x, p.y, p.z, 1));
    }
}

The i-th column is set from v. i must be from 0 to 3 inclusive.
