這篇會補全功能上的限制或處理，
像是輸到誰就只能誰來回答，
與錯誤處理，
或是回答過的不可以再使用。

流程

開局時限制

1. 判斷發起者與按下的人是否一樣

if interaction.user.id != self.author.id:
    await interaction.response.send_message("你不是發起者喔w", ephemeral=True)

2. 當確認為已開始模式: 開局按鈕 disable=True

for child in self.children:
    if type(child) == discord.ui.Button:
         child.disabled = True

await interaction.response.edit_message(view=self)

遊戲進行中

1. 判斷此局與按下的人是否為本人

if interaction.user.id != setting.playerList[setting.round]:
     return await interaction.response.send_message(f"還沒輪到你喔w", ephemeral=True)

2. 輸入不對的值

try: playerInput = int(playerInput)
except: return await interaction.response.send_message(f"請輸入 {setting.minVal + 1}～{setting.maxVal} 的整數", ephemeral=True)

if playerInput < setting.minVal or playerInput > setting.maxVal:
    return await interaction.response.send_message(f"請輸入 {setting.minVal + 1}～{setting.maxVal} 的整數", ephemeral=True)
