到目前为止，我自己已经找到了大部分代码。我试图制作一个基于文本的小游戏。我遇到麻烦的是，我似乎无法使随机数滚动正确循环。当它循环时，它只是循环最后滚动的东西。这是我的代码，整个事情。

在你杀死妖精后，它只是循环问题，而不是实际上回来并运行损坏代码等。我做错了什么？
答案 0 :(得分：1)
这是因为你的Goblin的HP死后你不会重置它。您的代码非常庞大，但这就是为什么您的代码没有按预期工作的想法：
// You only create a single Goblin instance in your scope
monster Goblin = new monster();
Goblin.name = "Goblin";
Goblin.health = 5;
Goblin.damage = 1;
...
while(true)
if(roll < 10) {
switch(randomNum) {
...
case 4:
System.out.println("You've run into a goblin! Attack or Defend?");
String action = scanner1.nextLine();
while(Goblin.health > 0) {
if(action.equals("Attack")) {
Goblin.health = Goblin.health - Player.damage;
System.out.println("You've done " + Player.damage + " damage to Goblin. Goblin has "+ Goblin.health + " health remaining.");
while(true){
if(Goblin.health <= 0){
System.out.println("You have slain the Goblin! Continue to move forward.");
break;
}
}
} else if(action.equals("Defend")) {
// Redacted
}
}
// You need to reset the Goblin's health here.
break;
case 5:
...
}
}
你永远不会在任何地方重置地精的健康状况！
简单的解决方法是将case 4的结尾更改为：
case 4:
// All your other handling here
Goblin.health = 5;
break;
case 5:
答案 1 :(得分：0)
mauzel是正确的。你没有重置健康状况，因此它陷入了循环
while(Goblin.health > 0)
我想在答案中添加更多内容。避免始终使用以下
while(true)
会导致无限循环。而是使用标志
boolean something = true
while(something)
{
//do something
}
因此，您可以在需要时轻松将标志设置为false。
此外，当您进入循环时，您已经
while(true)
if(roll < 10){
}
我建议删除if条件并将其更改为
while (roll != 10)
{
}
尝试将所有事件分解为方法，以便于调试和查找问题，我希望您使用调试器（调试时很容易发现）
答案 2 :(得分：0)
变量roll没有递增，因此您无休止地评估switch(randomNum)语句，其值为randomNum。这就是为什么即使在敌人被杀之后它仍然重复同样的情况。
