説明

衝突したオブジェクトのコライダー情報

衝突したオブジェクトがひとつ以上のコライダーがある場合に役に立ちます。このプロパティーを使用して、オブジェクトだけでなく特定のコライダーを判定できます。

Note that some functions that return a single RaycastHit2D will leave the collider as NULL which indicates nothing hit. RaycastHit2D implements an implicit conversion operator converting to bool which checks this property allowing it to be used as a simple condition check for whether a hit occurred or not.

using UnityEngine;
using System.Collections;

//Attach this script to an empty gameobject. //When you click on a sprite with a collider it will tell you it's name. public class ExampleClass : MonoBehaviour { void Update() { //If the left mouse button is clicked. if (Input.GetMouseButtonDown(0)) { //Get the mouse position on the screen and send a raycast into the game world from that position. Vector2 worldPoint = Camera.main.ScreenToWorldPoint(Input.mousePosition); RaycastHit2D hit = Physics2D.Raycast(worldPoint, Vector2.zero);

//If something was hit, the RaycastHit2D.collider will not be null. if (hit.collider != null) { Debug.Log(hit.collider.name); } } } }
