GameObject.tag

Description

此游戏对象的标签。

可使用标签来识别游戏对象。 使用标签前，必须在标签和层管理器中声明它们。

注意：您不应通过 Awake() 或 OnValidate() 方法设置标签。这是因为组件唤醒的顺序是不确定的，因此可能导致意外行为，例如标签在唤醒时被覆盖。如果尝试执行此操作，Unity 将生成一条警告：“SendMessage cannot be called during Awake, CheckConsistency, or OnValidate”。

public class CollisionGameObjectExample : MonoBehaviour
{
    //Detect collisions between the GameObjects with Colliders attached
    void OnCollisionEnter(Collision collision)
    {
        //Check for a match with the specified name on any GameObject that collides with your GameObject
        if (collision.gameObject.name == "MyGameObjectName")
        {
            //If the GameObject's name matches the one you suggest, output this message in the console
            Debug.Log("Do something here");
        }

        //Check for a match with the specific tag on any GameObject that collides with your GameObject
        if (collision.gameObject.tag == "MyGameObjectTag")
        {
            //If the GameObject has the same tag as specified, output this message in the console
            Debug.Log("Do something else here");
        }
    }
