Java角色扮演游戏

Question

试图在java中设计一个角色扮演游戏，在选择"a“并输入名称作为目标后，代码停止。不知道是怎么回事。试着改一个for，但是没有什么效果。事先非常感谢

Answer 1

这里有一个无限的循环

            for(int m=0; m<Player.size()-1; i++){

将i++更改为m++

您的代码中还有另一个问题：

            for(int j=0; j<Player.size()-1; j++){
                Player.get(j);
                String targetName=name;
                if(target.equals(targetName)){
                     hitp=Creature.getHitpoints(name);  
                }
                else{
                j++;
            }

在这里，您将得到第j个玩家，但是您在任何地方都不使用它，您只需将targetName分配给正在攻击的当前玩家名。正确的方法是

String targetName = Player.get(j).getName();

一些建议：

• 将Player重命名为Player，java约定使用低分数名作为变量，并且复数将记住您是一个列表。
• java有一个内置的for循环，它更直观，我会将上面的for循环更改为如下所示： for(生物targetPlayer: Player){ String targetName = targetPlayer.getName()；if(target.equals(targetName)){ hitp=targetPlayer.getHitpoints(名称)；}
