밥이 무한생성이 되지 않고 하나밖에 안나와요


using System.Collections;

using System.Collections.Generic;

using UnityEngine;

using UnityEngine.UI;


public class gameManager : MonoBehaviour

  public GameObject food;

  public GameObject dog;

  public GameObject normalCat;

  int level = 0;

  int cat = 0;


  void Awake()

  {

    I = this;

  }

  void Start()

  {

    Time.timeScale = 1f;

    InvokeRepeating("makeFood", 0.0f, 0.05f);

    InvokeRepeating("makeCat", 0.0f, 1f);

  }


  // Update is called once per frame

  void Update()

  {

    }

  }

    Instantiate(normalCat);

    if (level == 1)

    {

      float p = Random.Range(0, 10);

      if (p < 2) Instantiate(normalCat);

    }

    else if (level == 2)

    {

      float p = Random.Range(0, 10);

      if (p < 5) Instantiate(normalCat);

    }

    else if (level >= 3)

    {

      float p = Random.Range(0, 10);

      if (p < 6.5) Instantiate(normalCat);

      Instantiate(fatCat);

    }

  }


  public void gameOver()

  {

    Time.timeScale = 0f;

    retryBtn.SetActive(true);

  }


  public void addCat()

  {

    cat += 1;

    level = cat / 5;


    levelText.text = level.ToString();

    levelFront.transform.localScale = new Vector3((cat - level * 5) / 5.0f, 1.0f, 1.0f);

  }

}


일단 보류해두고 진도를 끝까지 나갔는데

마찬가지로 고양이도 무한생성이 안되네요


콘솔에 오류가 엄청 많이 뜨는데

UnassignedReferenceException: The variable dog of gameManager has not been assigned.

You probably need to assign the dog variable of the gameManager script in the inspector.

gameManager.makeFood () (at Assets/Scripts/gameManager.cs:44)


UnassignedReferenceException: The variable normalCat of gameManager has not been assigned.

You probably need to assign the normalCat variable of the gameManager script in the inspector.

UnassignedReferenceException: The variable retryBtn of gameManager has not been assigned.

You probably need to assign the retryBtn variable of the gameManager script in the inspector.
