如何更改 C# 中的 integer 值？

Question

我制作了一个名为 lifePoints 的 integer 然后我设置了一个 If 语句将整数的值从 100 更改为 90 如何

int lifePoints = 100;
// not a full code but just giving an explanation
if (player == ("attackthem!"))
  {

    change integer value here. how?

  }

我搜索了谷歌，结果将字符串更改为 integer。

Answer 1

{
   lifePoints -= 10;
}

对应于

{
   lifePoints = lifePoints - 10;
}

Answer 2

如果要将其设置为90 ，则：

lifePoints = 90;

如果要减去10 ，则：

lifePoints -= 10; 或： lifePoints = lifePoints - 10;

Answer 3

int lifePoints = 100;
// not a full code but just giving an explanation
if (player == ("attackthem!"))
  {

    lifePoints = 90; //CHANGE the integer's value from 100 to 90

  }
