等待协同路由完成[复制]

coroutine unity5 unity3d c#

在那之后我有一次合作 N 秒清除文本并将其恢复为原始形状。问题是,第一次返回后,协同程序就再也不会继续了( wait for seconds ).

void OnMouseDown()
{
    bool safeDestroy = false;

    IGatherable gather = CharacterCommands.character.GetComponent<IGatherable>();
    if(gather != null)
    {
        switch(itemID)
        {
        case 3:
            Drops[] d = ChestDrop.GetItemFromDropStash(drops, gather, this); //Here is function that is starting function with coroutine PROBLEM
            if(d.Length == 0)
            {
                safeDestroy = true;
            }
            else
            {
                drops = d;
            }
            break;
        default:
            if(ItemDatabase.GetItem(itemID).maxStackable < Inventory.GetCoins() + amount)
            {
                Parameters.centerText.text = "Not enough space in your bag!";
                safeDestroy = Parameters.clearText(Parameters.centerText, 3, this); //Coroutine i had same problem but done it this way.
            }
            else
            {
                gather.GatherItem(itemID, amount);
                safeDestroy = true;
            }
            break;
        }
    }
    if(safeDestroy)
    {
        Destroy(this.gameObject);
    }
}

这是函数本身:

public static Drops[] GetItemFromDropStash(Drops[] drops, IGatherable gather, MonoBehaviour justToStartCoroutine)
{
    foreach(Drops drop in drops)
    {
        int r = UnityEngine.Random.Range(1, 101);
        if(r < drop.chance)
        {
            if(ItemDatabase.GetItem(drop.itemID).maxStackable > Inventory.GetItemFromInventoryById(drop.itemID).amount + drop.amount)
            {
                Inventory.AddItemToInventory(drop.itemID, drop.amount);
                Parameters.centerText.text = "+" + drop.amount + " " + ItemDatabase.GetItem(drop.itemID).itemName;
                switch(ItemDatabase.GetItem(drop.itemID).itemRarity)
                {
                case ItemRarity.common:
                    Parameters.centerText.color = Color.gray;
                    break;
                case ItemRarity.normal:
                    Parameters.centerText.color = new Color(80, 100, 255);
                    break;
                case ItemRarity.rare:
                    Parameters.centerText.color = new Color(255, 80, 80);
                    break;
                case ItemRarity.special:
                    Parameters.centerText.color = new Color(200, 0, 220);
                    break;
                case ItemRarity.legacy:
                    Parameters.centerText.color = new Color(199, 224, 0);
                    break;
                case ItemRarity.legendary:
                    Parameters.centerText.color = new Color(224, 169, 0);
                    break;

                }
                bool t = Parameters.clearText(Parameters.centerText, 3, justToStartCoroutine);

                int i = Array.IndexOf(drops, drop);
                List<Drops> tmp = new List<Drops>(drops);
                tmp.RemoveAt(i);
                drops = tmp.ToArray();
            }
            else if (Inventory.CheckForFreeSpaceInInventory() == true)
            {
                Inventory.AddItemToInventoryToNewSlot(drop.itemID, drop.amount);
                Parameters.centerText.text = "+" + drop.amount + " " + ItemDatabase.GetItem(drop.itemID).itemName;
                switch(ItemDatabase.GetItem(drop.itemID).itemRarity)
                {
                case ItemRarity.common:
                    Parameters.centerText.color = Color.gray;
                    break;
                case ItemRarity.normal:
                    Parameters.centerText.color = new Color(80, 100, 255);
                    break;
                case ItemRarity.rare:
                    Parameters.centerText.color = new Color(255, 80, 80);
                    break;
                case ItemRarity.special:
                    Parameters.centerText.color = new Color(200, 0, 220);
                    break;
                case ItemRarity.legacy:
                    Parameters.centerText.color = new Color(199, 224, 0);
                    break;
                case ItemRarity.legendary:
                    Parameters.centerText.color = new Color(224, 169, 0);
                    break;

                }
                bool t = Parameters.clearText(Parameters.centerText, 3, justToStartCoroutine);

                int i = Array.IndexOf(drops, drop);
                List<Drops> tmp = new List<Drops>(drops);
                tmp.RemoveAt(i);
                drops = tmp.ToArray();
            }
            else
            {
                Parameters.centerText.text = "Not enough space in inventory!";
                bool t = Parameters.clearText(Parameters.centerText, 3, justToStartCoroutine);
            }
        }
    }
    return drops;
}

我如何才能实现我的项目(在哪里 OnMouseDown() 是)在协同程序完成之前不会销毁?

如果您想等待一个协程完成……那么该方法也必须是一个协程。

根据具体情况,您有3种选择:

yield .
- 您还可以将委托传递到当前协同路由并将其用作回调,然后现有协同路由的每次使用都可以提供自己的回调委托。然后,“等待完成”代码进入该委托。
将当前的非协程方法转换为协程。
创建一个新的协同路由,将需要等待其他协同路由的代码放入其中,包括对现有协同路由的调用, 产量 在另一次合作中。
