【Unity】GetComponentsInChildren で引数の型情報を文字列で渡せるようにする拡張メソッド

ソースコード

using UnityEngine;

public static class GameObjectExt
{
    public static Component[] GetComponentsInChildren( this GameObject self, string type, bool includeInactive )
    {
        return self
            .GetComponentsInChildren<Transform>( includeInactive )
            .Select( c => c.gameObject.GetComponent( type ) )
            .Concat( new []{ self.GetComponent( type ) } )
            .Where( c => c != null )
            .ToArray();
        ;
    }
}

使い方

var list = gameObject.GetComponentsInChildren( "BoxCollider" );
