我是Java的初学者。我正在制作基本的回合制游戏，但是战斗系统存在问题。我用选择的武器攻击随机选择的敌人，直到其死亡，但是我不知道如何降低我的生命值。
我在Character类中尝试了以下方法：
public void attack(int damageAmount, int myHealth) {
if (damageAmount >= this.health || myHealth<=0) {
this.health = 0;
System.out.println( this.name + " is dead!");
this.dead = true;
} else {
this.health -= damageAmount;
System.out.println("The remaining life of " + this.name + " is: " + this.health);
player.setHealth(myHealth-this.damage);
System.out.println("Your remaining HP: "+ myHealth);
这是行不通的，因为在Character类中无法访问“ player.setHealth（）”。
我该如何解决？我应该为战斗系统再上一堂课吗？
另外，可以通过使用继承或接口使代码更简单吗？
在此先感谢大家！

最佳答案
我对循环逻辑做了一些更改，希望对您有所帮助：
while (!characterList.get(whichCharacter).isDead() && !player.isDead()) {
switch (choice) {
case 1:
myDamage = 5;
break;
case 2:
myDamage = sword.getWeaponDamage();
break;
case 3:
myDamage = bow.getWeaponDamage();
break;
case 4:
myDamage = crossBow.getWeaponDamage();
break;
case 5:
myDamage = revolver.getWeaponDamage();
break;
default:
myDamage = 5;
}
while (!characterList.get(whichCharacter).isDead() && !player.isDead()) {
characterList.get(whichCharacter).attack(myDamage, myHealth);
player.attack(characterList.get(whichCharacter).getDamage(), player.getHealth());
//characterList.get(whichCharacter).attack(characterList.get(whichCharacter).getDamage(), player.getHealth());
}
}
