unity transform 常用操作

Posted 2021-02-07 programmingadorablenew

1.寻找物体

1.1 寻找满足条件的子物体

`    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 寻找一组满足条件的子物体

`    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. 操作一组物体

2.1 对一组满足条件物体进行操作

`    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 常用扩展方法

`    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);
}
