JavaScript => public function SetColumn(i: int, v: Vector4): void;
C# => public void SetColumn(int i, Vector4 v);

Parameters 参数

Description 描述

Sets a column of the matrix.

设置矩阵的一列。

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

使用这个来构建一个变换矩阵，这个矩阵使用right，up和forward向量。

JavaScript:

// 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));
	}

C#:

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.

第i列设置为v，i必须在0到3之间。
