Question

JavaScript => var worldToCameraMatrix: Matrix4x4;
C# => Matrix4x4 worldToCameraMatrix;

Description 描述

Matrix that transforms from world to camera space.

从世界到相机空间的变换矩阵。

Use this to calculate the camera space position of objects or to provide custom camera's location that is not based on the transform.

用这个计算物体的相机空间位置或提供自定义的位置，这个位置不是基于变换的。

Note that camera space matches OpenGL convention: camera's forward is the negative Z axis. This is different from Unity's convention, where forward is the positive Z axis.

注意相机空间和OpenGl的约定相匹配，相机的前面为Z轴负方向，这不同于Unity的约定，向前为Z轴正向。

If you change this matrix, the camera no longer updates its rendering based on its Transform. This lasts until you call ResetWorldToCameraMatrix.

如果你改变这个矩阵，相机的渲染不再基于它的Transform更新，知道调用ResetWorldToCameraMatrix.

JavaScript:

	// Offsets camera's rendering from the transform's position.	var offset : Vector3 = Vector3 (0,1,0);
 
	function LateUpdate () {
		// Construct a matrix that offsets and mirrors along
		// Z axis. Because camera space has mirrored Z with respect
		// to the rest of Unity.
		var camoffset : Vector3 = Vector3 (-offset.x, -offset.y, offset.z);
		var m : Matrix4x4 = Matrix4x4.TRS (camoffset, Quaternion.identity, Vector3 (1,1,-1));
		// Override worldToCameraMatrix to be offset/mirrored
		// transform's matrix.
		camera.worldToCameraMatrix = m * transform.worldToLocalMatrix;
	}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    public Vector3 offset = new Vector3(0, 1, 0);
    void LateUpdate() {
        Vector3 camoffset = new Vector3(-offset.x, -offset.y, offset.z);
        Matrix4x4 m = Matrix4x4.TRS(camoffset, Quaternion.identity, new Vector3(1, 1, -1));
        camera.worldToCameraMatrix = m * transform.worldToLocalMatrix;
    }
}
