More than 5 years have passed since last update.

delegateを使う。

呼び出し側

using UnityEngine;

public class SampleMain {

    public void Start () {

        SampleSub sub = new SampleSub();
        sub.hoge(Callback);
    }

    public void Callback ( string msg ) {

        Debug.Log("Callback : " + msg); // Callback : おわったよ
    }
}

呼び出され側

using UnityEngine;

public class SampleSub {

    public delegate void onComplete( string msg );

    public void hoge ( onComplete callback ) {

        // 処理が終わったら
        callback("おわったよ");
    }
}
