我有一个骰子游戏,我正在尝试将骰子滚动后选择的骰子图像更改为“死亡骰子”图像。我已经尝试了我能想到的一切,我总是在索引中找到值“0”或其他东西,但从来没有找到正确的 Die。

选择骰子时,它会将其值设置为负数。示例我选择 6 它将值更改为 -6 并将模具更改为 -6 模具图像

我怎样才能让它显示并保持我想要的“死”图像。

这是获取图像的区域

            //Get the Dice Images
           public Integer getImage(int index) {
               if (diceValues[index] == 0) {
                       return letterImages.get(index);

               } else {
                       return diceImages.get((diceValues[index]));
               }
           }

我试过改变

return letterImages.get(index);

对于所有可能的组合,当我得到它来更改图像时,它总是以“0”或当前选择的骰子数量或其他一些我不确定它是如何得出的数字结束。

这是整个 DieManager 类

由于您的 rollDice() 方法中的以下行,骰子值永远不会在滚动中为零:

diceValues[j] = (int) ((Math.random() * 6) + 1);

这对我来说似乎是合乎逻辑的。为什么骰子上的价值永远为零?
