Question

运行此脚本时，按1并单击Enter会显示两个口袋妖怪的生命值，它将您的攻击生命值减去敌人生命值。当您或敌人击中0或小于0的生命值时，它应该停止并只显示谁在控制台日志中获胜。取而代之的是显示消息。

因此，如果您的功率为-10 hp，则需要再承受一击。

let firstFight = false;

while (!firstFight) {
  let fightOptions = prompt("1. Fight, 2.Items, 3.Potions " + wildPokemon[0].name + ":" + wildPokemon[0].hp + " " + pokeBox[0].name + ":" + pokeBox[0].hp);
  if (fightOptions == 1) {

    if (!firstFight) {

      if (wildPokemon[0].hp <= 0) {
        console.log("You have won!");
        firstFight = true;
      } else {
        let attack1 = wildPokemon[0].hp -= pokeBox[0].attack.hp;
        console.log(wildPokemon[0].hp);
      }

      if (pokeBox[0].hp <= 0) {
        console.log(wildPokemon[0] + " has killed you");
        firstFight = true;
      } else {
        let attack2 = pokeBox[0].hp -= wildPokemon[0].attack.hp;
        console.log(pokeBox[0].hp);
      }
    }

  } else if (fightOptions == 2) {

  } else if (fightOptions == 3) {

  } else {

  }

}

有什么方法可以使这段代码更有效？

您可以简单地添加另一个if条件，以检查玩家的生命是否仍然大于还是等于“ 0”还是小于等于“ 0”。

这样，您就不必去下一回合检查玩家的生命，而且它摆脱了多余的条件语句...

    if (fightOptions == 1) {

       let attack1 = wildPokemon[0].hp -= pokeBox[0].attack.hp;
       console.log(wildPokemon[0].hp);
       if (wildPokemon[0].hp <= 0) {
          console.log("You have won!");
          firstFight = true;
       }

      if (!firstFight){
         let attack2 = pokeBox[0].hp -= wildPokemon[0].attack.hp;
         console.log(pokeBox[0].hp);
         if (pokeBox[0].hp <= 0) {
            console.log(wildPokemon[0] + " has killed you");
            firstFight = true;
         }
      }

   }

Answer 2

当条件为false时，循环将停止，但在这种情况下，将其设置为false，则不会停止，因为您未明确确定条件。您可以通过两种方式进行操作。

第一：

while（！firstFight == false）

第二：

var firstFight = true; while（firstFight）然后在if else语句中将firstFight设置为false。

Answer 3

问题是，要检查点是否等于或小于零后，要减去这些点。您可以通过以下方式进行检查：

let firstFight = false;

while (!firstFight) {
  let fightOptions = prompt("1. Fight, 2.Items, 3.Potions " + wildPokemon[0].name + ":" + wildPokemon[0].hp + " " + pokeBox[0].name + ":" + pokeBox[0].hp);
  if (fightOptions == 1) {
    wildPokemon[0].hp -= pokeBox[0].attack.hp;

    if (wildPokemon[0].hp <= 0) {
      console.log("You have won!");
      firstFight = true;
    } else {
      console.log(wildPokemon[0].hp);
    }

    pokeBox[0].hp -= wildPokemon[0].attack.hp;
    if (!firstFight && pokeBox[0].hp <= 0) {
      console.log(wildPokemon[0] + " has killed you");
      firstFight = true;
    } else {
      console.log(pokeBox[0].hp);
    }
  } else if (fightOptions == 2) {

  } else if (fightOptions == 3) {

  } else {

  }

}

JS while循环不会真的停止
