我试图统一制作一个C＃脚本，而该脚本在IEnumerator的第61行（脚本末尾的行首和末尾用**标记）中说了'foodManager.foodEat(GameObject)': not all code paths return a value。这里有什么问题，我该如何解决？
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class FoodManager : MonoBehaviour
{
public bool[] isFull;
public GameObject[] slots;
public GameObject[] itemNames;
public GameObject[] itemImages;
public GameObject[] itemAmounts;
public GameObject foodObject;
public string[] foodNames;
public Sprite[] foodImages;
public Sprite[] foodHalfImages;
public GameObject foodPanel;
void Update()
{
for(int i = 0; i < 6; i++)
{
if (isFull[i] == true)
slots[i].SetActive(true);
if (isFull[i] == false)
slots[i].SetActive(false);
}
}
private void addItem(int max, string itemName, GameObject itemImage, int addingAmount, string foodName)
{
for (int j = 0; j < max; j++)
{
if (isFull[j] == true && itemNames[j].GetComponent<Text>().text == itemName)
itemAmounts[j].GetComponent<Text>().text = (int.Parse(itemAmounts[j].GetComponent<Text>().text) + addingAmount).ToString();
if (isFull[j] == false)
{
isFull[j] = true;
itemNames[j].GetComponent<Text>().text = itemName;
itemAmounts[j].GetComponent<Text>().text = addingAmount.ToString();
itemImages[j].GetComponent<Image>().sprite = foodImages[j];
break;
}
}
}
public void foodButtonsBehavior(int a)
{
if(a >= 0 && a < 6)
{
StartCoroutine(foodEat(slots[a]));
}
if(a == 6) //exit Button
foodPanel.SetActive(false);
}
**public IEnumerator foodEat(GameObject slot)**
{
foodPanel.SetActive(false);
}
}
我想使用IEnumenator，因为我想将WaitForSeconds（）添加到脚本中，但是我还没有添加。请帮助我解决这个问题，这非常重要！
public void foodEat(GameObject slot)
{
foodPanel.SetActive(false);
}
这应该可以解决您的问题。
