public Vector3 WorldToViewportPoint (Vector3 position);


ワールド空間の position をビューポート空間に変換します。

Viewport space is normalized and relative to the camera. The bottom-left of the camera is (0,0); the top-right is (1,1). The z position is in world units from the camera.

// Finds out whether target is on the left or right side of the screen
using UnityEngine;
using System.Collections;

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

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

void Update() { Vector3 viewPos = cam.WorldToViewportPoint(target.position); if (viewPos.x > 0.5F) print("target is on the right side!"); else print("target is on the left side!"); } }
