我正在尝试制作一个非常简单的游戏(即使没有界面)。您应该键入要执行的操作(攻击或阻止)。但为什么我的(enemy_hp > 0 || hp > 0
)陈述不起作用?循环永远。
public class Game {
public static void main(String[] args){
int hp = 10, enemy_hp = 10;
String attack = "attack";
String block = "block";
Scanner userInput = new Scanner (System.in);
while (enemy_hp > 0 || hp > 0) {
System.out.println("It is your turn, attack or try to block");
int your_block_chance1 = (int) (Math.random() * 4); //Chance to block an attack
int enemy_block_chance1 = (int) (Math.random() * 4);
String action = userInput.next();
if (action.equals(attack)){
System.out.print("You attacked your enemy and ");
if (enemy_block_chance1 == 0) {
System.out.println("he blocked it");
}
else if (enemy_block_chance1 != 0){
enemy_hp = enemy_hp - 2;
System.out.println("managed to hit, now his hp is " +enemy_hp);
}
}
else if (action.equals(block)){
System.out.println("You dicided to block");
your_block_chance1 = 0;
}
System.out.print("It is your enemy turn, he decided to ");
int enemy_action = (int) (Math.random() * 2);
if (enemy_action == 1){
System.out.print("attack you,");
if (your_block_chance1 == 0){
System.out.println(" but you blocked it");
}
else if (your_block_chance1 != 0){
hp = hp - 2;
System.out.println(" and you didn't block it, now your hp is " +hp);
}
}
else if (enemy_action != 1){
System.out.print("do a heavy attack");
int heavy_attack_chance = (int) (Math.random() * 2);
if (heavy_attack_chance == 1){
System.out.println(" but failed");
}
else if (heavy_attack_chance != 1){
if (your_block_chance1 == 0){
System.out.println(" but you blocked it");
}
else if (your_block_chance1 != 0){
hp = hp - 4;
System.out.println(" and he managed to hit you really hard, now your hp is " +hp);
}
}
}
}
if (hp <= 0){
System.out.println("You failed");
}
else if (enemy_hp <= 0){
System.out.println("You won!");
}
}
}
答案 0 :(得分:8)
当其中一名玩家死亡时你想停止吗?那么你应该放一个&amp;&amp ;.因为||除非两名球员的马力低于0,否则永远不会是假的。
答案 1 :(得分:2)
如果你想在 敌人或玩家的生命值下降到零或以下时停止,那么你希望你的循环条件使用逻辑AND运算符而不是OR:< / p>
ReportForm
此继续,而两者均高于零。因此,当其中任何一个(或两个)为零或以下时,停止。
答案 2 :(得分:2)
您的情况使用||
或OR。这意味着你的循环将继续,而敌人的HP是积极的,或者玩家HP是积极的(意味着它会在敌人的HP达到0后继续)。将其更改为&&
。
