Question

这是我的情况。我有四个类：Inventory.cs，InventoryTab.cs，ItemDatabase.cs，BaseItem.cs（以及一些从BaseItem派生的项目，如武器，消耗品等）

库存创建新的InventoryTabs（消耗品，武器，护甲），每个InventoryTab都有一个BaseItem列表。

然后调用

Inventory.AddItemByID(int ID, int Amount)，它会检查ItemDatabase.cs的ID，并在游戏开始时将项目预先加载到列表中。

好的，现在你已经掌握了我的库存运行的基本信息，这里是我的问题：

在InventoryTab中：

int Column, Row; //Declared at the top of the class

for (int i = 0; i < ItemList.Count; i++)
{
    Column++;
    if (Column > gridSize.X)
    {
        Column = 0; Row++; //Row is not limited because my inventory will be unlimited in height
    }

    ItemList[i].gridLocation = new Point(column, row);
}

虽然我认为这样可行，但它会在顶部创建一个项目，然后快速跳到右侧，然后向下跳过一行，然后重复。如果我通过KeyboardState添加更多项目，它会闪烁大量项目，然后消失。

我确定它是因为它在一个循环中分配了gridLocation的值，但是我再也不知道如何以任何其他方式解决它。

我需要做的是只在ItemList中为每个BaseItem分配一次gridLocation。

使用@deathismyfriend，您可以在每个位置运行嵌套for循环：

int pos; //Declared at the top of the class

pos = 0;
for (int x = 0; x < gridsize.X; x++) // x represents column
{
    for (int y = 0; y < ItemList.Count / gridsize.X; y++) // y represents row
    {
        // In the above (ItemList.count / gridsize.X) = number of rows needed
        ItemList[pos].gridLocation = new Point(x, y);
        pos++;
    }
}

那应该做你想要的。
