TMP_DropDownサンプル

using UnityEngine;
using UnityEngine.UI;
using UniRx;
using TMPro;
public class SampleScene : MonoBehaviour
{
    void Start()
    {
        Text text = GameObject.Find("Text").GetComponent<Text>();
        TMP_Dropdown tmpDropdown = GameObject.Find("TmpDropdown").GetComponent<TMP_Dropdown>();
        tmpDropdown.ObserveEveryValueChanged(_ => _.value)
            .Subscribe(index => {
                var value = dropdown.options[index].text;
                text.text = value;
            })
            .AddTo(gameObject);
    }
}

UnityUIComponentExtensions.csへusing TMPro;が追加できない問題

別途、UnityUIExtensionsを作れば良い？
