public Vector3 WorldToScreenPoint (Vector3 position);

説明

ワールド空間の position をスクリーン空間に変換します。

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.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { public Transform target; Camera cam;

void Start() { cam = GetComponent<Camera>(); }

void Update() { Vector3 screenPos = cam.WorldToScreenPoint(target.position); Debug.Log("target is " + screenPos.x + " pixels from the left"); } }
