Camera.WorldToScreenPoint 世界转屏幕位置

function WorldToScreenPoint (position : Vector3) : Vector3

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。

using UnityEngine;
using System.Collections;

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

var target : Transform;

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