説明

ゲームオブジェクトのタグ

タグはゲームオブジェクトを見分けるために使用することができます。 タグを使用する前に Tags and Layers マネージャー でタグ名を宣言する必要があります。

Note: You should not set a tag from the Awake() or OnValidate() method. This is because the order in which components become awake is not deterministic, and therefore can result in unexpected behaviour such as the tag being overwritten when it is awoken. If you try this, Unity will generate a warning reading "SendMessage cannot be called during Awake, CheckConsistency, or OnValidate".

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { void Example() { Debug.Log("Transform Tag is: " + tag); } }
