unity transform 常用操作

1.尋找物體

1.1 尋找滿足條件的子物體

`    public static Transform FindObj(Transform transform, Func<Transform, bool> condition, bool isGrandsonObj = false)

{

    Transform[] allChilds = transform.GetComponentsInRealChildren<Transform>(isGrandsonObj);

    foreach (Transform child in allChilds)

    {

        if (condition(child))

        {

            return child;

        }

    }

    return transform;

}

public static Transform FindObj(Transform transform, string tag, bool isGrandsonObj = false)

{

    return FindObj(transform, (t) => t.tag.Equals(tag), isGrandsonObj);

}`

1.2 尋找一組滿足條件的子物體

`    public static List<Transform> FindObjs(Transform transform, Func<Transform, bool> condition, bool isGrandsonObj = false)

{

    Transform[] allChilds = transform.GetComponentsInRealChildren<Transform>(isGrandsonObj);

    List<Transform> list = new List<Transform>();

    foreach (Transform child in allChilds)

    {

        if (condition(child))

        {

            list.Add(child);

        }

    }

    return list;

}

public static List<Transform> FindObjs(Transform transform, string tag, bool isGrandsonObj = false)

{

    return FindObjs(transform, (t) => t.tag.Equals(tag), isGrandsonObj);

}`

2. 操作一組物體

2.1 對一組滿足條件物體進行操作

`    public static void AddActionObjects(Transform[] transform, Func<Transform, bool> condition, Action<Transform> action)

{

    foreach (Transform child in transform)

    {

        if (condition(child))

        {

            action(child);

        }

    }

}`

2.2 常用擴充套件方法

`    public static void AddActionObjects(Transform[] transform, Action<Transform> action)

{

    AddActionObjects(transform, (t) => true, action);

}

public static void AddActionObjects(Transform transform, Func<Transform, bool> condition, Action<Transform> action, bool isGrandsonObj = false)

{

    Transform[] allChilds = transform.GetComponentsInChildren<Transform>(isGrandsonObj);

    AddActionObjects(allChilds, condition, action);

}

public static void AddActionObjects(Transform transform, Action<Transform> action, bool isGrandsonObj = false)

{

    AddActionObjects(transform, (t) => true, action, isGrandsonObj);

}

public static void AddActionObjects(Transform transform, string tag, Action<Transform> action, bool isGrandsonObj = false)

{

    AddActionObjects(transform, (t) => t.tag.Equals(tag), action, isGrandsonObj);

}
