パラメーター

eyeOptional argument that can be used to specify which eye transform to use. Default is Mono.

説明

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!"); } }
