All compiler errors have to be fixed before you can enter playmode! のエラー

Question

All compiler errors have to be fixed before you can enter playmode!
UnityEditor.SceneView:ShowCompileErrorNotification()
とエラーが出ました。
調べてみると、全角とかビルドのエラーらしいのですが結局なんのエラーかわかりません。

using UnityEngine;
using System.Collections;
using UnityEngine.UI;


public class GameDirector : MonoBehaviour {

	GameDirector hpGage;

	// Use this for initialization
	void Start () {
		this.hpGage = GameDirector.Find ("hpGage");
	}
	
	public void DecreaseHp(){
		this.hpGage.GetComponent<Image> ().fillAmount -= 0.1f;
}
}

using UnityEngine;
using System.Collections;

public class PlayerController : MonoBehaviour {

	// Use this for initialization
	void Start () {
	
	}
	
	// Update is called once per frame
	void Update () {
		if(Input.GetKeyDown(KeyCode.LeftArrow)){
			transform.Translate (-3, 0, 0);
	}
		if(Input.GetKeyDown(KeyCode.RightArrow)){
			transform.Translate (3, 0, 0);
		}
}
}

using UnityEngine;
using System.Collections;

public class ArrowController : MonoBehaviour {
	GameObject player;
	// Use this for initialization
	void Start () {
		this.player = GameObject.Find ("player");
	   
	}
	
	// Update is called once per frame
	void Update () {
		transform.Translate (0, -0.1f, 0);

		if(transform.position.y < -5.0f){
			Destroy (gameObject);
	}

	Vector2 p1 = transform.position;
	Vector2 p2 = this.player.transform.position;
	Vector2 dir = p1 -  p2 ;
	float d = dir.magnitude;
	float r1 = 0.5f;
	float r2 = 1.0f;

	if(d< r1 + r2){
		Destroy(gameObject);

			GameObject director = GameObject.Find ("GameDirector");
			director.GetComponent<GameDirector> ().DecreaseHp ();
}
}
}

using UnityEngine;
using System.Collections;

public class AllowGenerator : MonoBehaviour {
	public GameObject arrowPrefab;
	float span = 1.0f;
	float delta = 0;
	// Use this for initialization

	// Update is called once per frame
	void Update () {
		this.delta += Time.deltaTime;
		if(this.delta > this.span){
			this.delta = 0;
			GameObject go = Instantiate (arrowPrefab) as GameObject;
			int px = Random.Range (-6, 7);
			go.transform.position = new Vector3 (px, 7, 0);
	}
}
}

と４つのファイルに記述しました。
なんのエラーなのでしょうか？

Answer 1

そのエラーメッセージはエラーが出たよってメッセージで特に意味はありません。
真のエラーメッセージは多分その一つ上の行とかに出てるはず。
