我正在创建一款棋盘游戏，并决定为此目的选择 Google 表格。我已将问题简化为由一张纸和一个脚本组成的最小示例。

情况

Following points refer to my dice sheet:

• Cells B2:C5 contain available dices. First column contains dice sprites, second comma-separated dice face numbers.
  • 游戏设计视角：艺术家可以更改骰子图像。设计者可以改变骰子面的数字。两种类型的更改都会自动传播到引用骰子的单元格。
• Cells E2:I2 and E10:I10 contain particular throw. In each throw there's 1 to 5 references to dices in column B.
  • 游戏设计视角：有许多不同的游戏项目，每个项目可能都有不同的骰子来确定行动的结果。设计者可以添加或删除对骰子的引用，它将触发特定单元格的自动重新计算（在我们的例子中，这些单元格是K2 and K10).
• Cells beginning at K2 and K10 hold the result of the DICEFACES function applied to the ranges E2:I2 and E10:I10.
  • 游戏设计视角：骰子面矩阵将进一步用于计算骰子概率。为了简单起见，我将矩阵本身视为最终结果。

• DICEFACES是我在脚本编辑器中创建的自定义函数 文件Code.gs与样式表相关联。它返回一个矩阵 与所提供范围内的骰子相对应的骰子面。它是 正文如下：

  function DICEFACES(unused_ref_to_range_containing_dices)
  {
    var app  = SpreadsheetApp;
    var spr  = app.getActiveSheet();
  
    // In the end this array will hold the dice faces. For example two
    // 1d6 dices would result in [[1,2,3,4,5,6],[1,2,3,4,5,6]].
    //
    var Dices = [];
  
    // The the formula inside the active cell (i.e. the cell on which
    // we are calling this function). This is a string like:
    //
    // "=DICEFACES(E2:I2)"
    //
    var active_formula = spr.getActiveRange().getFormula();
  
    // Set item_range to the one pointed to by the formula. This could
    // be a range like E2:I2.
    //
    var item_range = spr.getRange(active_formula.match(/=\w+\((.*)\)/i)[1]);
  
    // Loop over dice cells in the item_range.
    //
    for (var i = 1; i <= item_range.getNumColumns(); i++)
    {
      // "=B2", "=B3", ...
      //
      var dice_formula = item_range.getCell(1, i).getFormula();
  
      // As soon as we encounter an empty formula, we skip (i.e. there are
      // no more dices).
      //
      if (dice_formula == "")
      {
        break;
      }
  
      // A reference to the cell containing the dice image. We don't really
      // need the image, the dice faces are of greater importance to us.
      //
      var dice_cell = spr.getRange(dice_formula.substr(1));
  
      // Move one column to the right prior to the dice_cell and retreive
      // the value of the cell. This is a string like "1,2,3,4,5,6".
      //
      var dice_csv = dice_cell.offset(0, 1).getValue();
  
      // Convert the CSV string to a javascript array like [1,2,3,4,5,6]
      // and push it to Dices.
      //
      Dices.push(dice_csv.split(",").map(Number));
    }
    return Dices;
  }
  

Problem

问题是当我改变列中的骰子面时C, the DICEFACE公式不会被重新计算。就在我创建之前截屏我添加了,4单元格的后缀C2正如你所看到的，没有4在细胞内N2。然而，如果我either重新保存Code.gs脚本文件or改变骰子E2:I2，重新计算立即发生。

我很确定我知道问题出在哪里：因为我正在遍历脚本中的单元格，所以工作表应用程序本身看不到列中单元格之间的引用链接C和公式K2 and K10。看看我的工作表，单元格引用可能类似于：

K4  <-- E2:I2   <-- B2, B3 (C is not here)
K10 <-- E10:I10 <-- B4, B5 (C is not here)

我的符号的含义A <-- B is If there's a change in range B, update cell A.

Question

我应该更改什么才能使修改骰子面后立即自动重新计算？如果这是不可能的，那么完成我的任务的最佳方法是什么？

问题是当我改变列中的骰子面时C, the DICEFACE公式不会被重新计算。

DIFACE 是自定义函数，当打开电子表格且自定义函数参数值发生更改时，会重新计算自定义函数。

考虑到上述情况，为了最大限度地减少对自定义函数的更改，请添加第二个参数作为触发器。

改变正则表达式

/=\w+\((.*)\)/i

to

/=\w+\((.*),.*\)/i

然后通过以下方式调用您的自定义函数

=DICEFACES(E2:I2,C2)

or

=DICEFACES(E2:I2,C2:C5)

OP自定义功能修改版
