Matrix4x4.SetColumn

SetColumn(i: int, v: Vector4): void;
void SetColumn(int i, Vector4 v);
def SetColumn(i as int, v as Vector4) as void

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));
    }
}
import UnityEngine
import System.Collections

public class ExampleClass(MonoBehaviour):

	public matrix as Matrix4x4 = Matrix4x4()

	def Start() as void:
		matrix.SetColumn(0, transform.right)
		matrix.SetColumn(1, transform.up)
		matrix.SetColumn(2, transform.forward)
		p as Vector3 = transform.position
		matrix.SetColumn(3, Vector4(p.x, p.y, p.z, 1))

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