使用变换创建外观干净的立方体

Question

所以有很多与此相关的帖子，但我似乎无法准确指出我的风格哪里出了问题，如果你们中的一些人认为这是对之前问题的重复，我深表歉意。

这个问题非常简单：我只是想随机掷骰子。 js 按预期工作，一切正常。问题是立方体看起来很尴尬，我不完全确定为什么。我通常对 css 相当熟练，但我对 3d 变换的处理不多，所以我缺乏直觉。如果您运行片段，您可以看到当立方体旋转时并非所有侧面都是光滑的，有些侧面看起来凹陷，我不确定为什么（特别是 1 和 2 侧面）。完整代码在下面的片段中：

const rollBtn = document.getElementById('roll');
const sides = ['one', 'two', 'three', 'four', 'five', 'six'];
const output = document.getElementById('dice_output');
let currentClass = '';

const rollDice = () => {
  let randomSide = sides[Math.floor(Math.random() * (6) + 1)];
  let currentSide = document.getElementById(randomSide);
  let generatedSide = `show-${randomSide}`;
  if (currentClass) {
    output.classList.remove(currentClass);
  }
  output.classList.add(generatedSide);
  currentClass = generatedSide;
}

rollBtn.addEventListener('click', rollDice);

Answer 1

您还需要将 #one 和 #two 翻译成 40px

const rollBtn = document.getElementById('roll');
const sides = ['one', 'two', 'three', 'four', 'five', 'six'];
const output = document.getElementById('dice_output');
let currentClass = '';

const rollDice = () => {
  let randomSide = sides[Math.floor(Math.random() * (6) + 1)];
  let currentSide = document.getElementById(randomSide);
  let generatedSide = `show-${randomSide}`;
  if (currentClass) {
    output.classList.remove(currentClass);
  }
  output.classList.add(generatedSide);
  currentClass = generatedSide;
  
}

rollBtn.addEventListener('click', rollDice);
