JavaScript => WorldToScreenPoint(position: Vector3): Vector3;
C# => Vector3 WorldToScreenPoint(Vector3 position);

Description 描述

Transforms position from world space into screen space.

从世界空间到屏幕空间变换位置。

Screenspace is defined in pixels. The bottom-left of the screen is (0,0); the right-top is (pixelWidth,pixelHeight). The z position is in world units from the camera.

屏幕空间以像素定义，屏幕左下为(0,0)，右上是(pixelWidth,pixelHeight)，Z的位置是以世界单位衡量的到相机的距离。

JavaScript:

	var target : Transform;	function Update () {
		var screenPos : Vector3 = camera.WorldToScreenPoint (target.position);
		print ("target is " + screenPos.x + " pixels from the left");
	}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    public Transform target;
    void Update() {
        Vector3 screenPos = camera.WorldToScreenPoint(target.position);
        print("target is " + screenPos.x + " pixels from the left");
    }
}
