我环顾四周，我不知道为什么它会不断推出一堆窗户。我还没有找到任何其他类似的帖子，但是如果有让我知道的话。我对java也很陌生，在观看视频后我决定尝试使用我自己的代码制作一些简单的游戏，所以如果我的道歉可能会有点麻烦。
代码：
import java.awt.event.*;
import java.util.Random;
import javax.swing.*;
public class Game extends JFrame {
// Game Variables
Enemies newEnemy = new Enemies();
String enemy;
static int enemyHealth;
static int enemyAttackDamage;
static String imput = "";
public static void main(String[] args) {
new Game();
}
public Game() {
// System Variables
boolean running = true;
JTextField textField1;
JTextArea textArea1;
// GUI Variables
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setSize(900, 600);
this.setLocationRelativeTo(null);
this.setResizable(false);
this.setTitle("Dungeon Drivers Alpha 0.2.3");
JPanel thePanel = new JPanel();
textArea1 = new JTextArea(33, 80);
textArea1.setText("Window launch was Successful.\n");
textArea1.setEditable(false);
textArea1.setLineWrap(true);
textArea1.setWrapStyleWord(true);
thePanel.add(textArea1);
JScrollPane scrollbar1 = new JScrollPane(textArea1,
JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED,
JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED);
thePanel.add(scrollbar1);
textField1 = new JTextField("", 80);
textField1.setText("Enter Text...");
thePanel.add(textField1);
this.add(thePanel);
this.setVisible(true);
// System Objects
Random rand = new Random();
// Player Variables
int health = 100;
int attackDamage = 50;
int numHealthPotions = 5;
int healthPotionHealAmount = 30;
int healthPotionDropChance = 25; // Percentage
// GAME
textArea1.append("\tWelcome to the Dungeon!"); // THIS IS THE LAST
// MESSAGE SEEN THEN IT
// CONTINUES TO OPEN
// WINDOWS
newEnemy.getEnemy();
FIGHT: while (running) {
textArea1.append("\n\t-------------------------------------\n");
textArea1.append("\t# A " + enemy + " has appeared! #");
while (enemyHealth > 1) {
textArea1.append("\n\tHealth: " + health);
textArea1.append("\t" + enemy + "'s Health: " + enemyHealth);
textArea1.append("\n\tWhat would you like to do?");
textArea1.append("\t1. Attack!");
textArea1.append("\t2. Drink Health Potion!");
textArea1.append("\t3. Run!\n");
while (running) {
textField1.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
imput = textField1.getText();
textField1.setText("");
}
});
if (imput.equals("1")) {
int damageDealt = rand.nextInt(attackDamage);
int damageTaken = rand.nextInt(enemyAttackDamage);
enemyHealth -= damageDealt;
health -= damageTaken;
if (enemyHealth < 1) {
textArea1.setText("");
}
textArea1.setText("");
textArea1.append(
"\t> You strike the " + enemy + " for " + damageDealt + " Damage.");
textArea1.append("\n\t> You recieve " + damageTaken + " in retaliation!");
if (health < 1) {
textArea1.append("You have no Health left so you ran away.");
break;
}
break;
} else if (imput.equals("2")) {
if (numHealthPotions > 0) {
health += healthPotionHealAmount;
numHealthPotions--;
textArea1.append("\t> You Drink a health potion for "
+ healthPotionHealAmount + "." + "\n\t> You now have " + health
+ " Health." + "\n\t> You have " + numHealthPotions
+ " Health Potions left.\n");
imput = "";
} else {
textArea1.append(
"\t> You have no Health Potions left! Kill enemies to get them.");
imput = "";
}
} else if (imput.equals("3")) {
textArea1.setText(null);
textArea1.append("\tYou run from the " + enemy + "!");
imput = "";
continue FIGHT;
}
imput = "";
}
imput = "";
}
}
}
}
另一个文件被命名为Enemies，这里是代码：
import java.util.Random;
import java.util.concurrent.ThreadLocalRandom;
public class Enemies {
public void getEnemy() {
Random rand = new Random();
String[] list = {"Skeleton", "Zombie"};
Game game = new Game();
String enemies = list[rand.nextInt(list.length)];
if(enemies.equals("Skeleton")) {
int maxHealth = 30;
int minHealth = 25;
Game.enemyHealth = ThreadLocalRandom.current().nextInt(minHealth, maxHealth + 1);
int maxAttackDamage = 15;
int minAttackDamage = 10;
Game.enemyAttackDamage = ThreadLocalRandom.current().nextInt(minAttackDamage, maxAttackDamage + 1);
game.enemy = enemies;
}
else if(enemies.equals("Zombie")) {
int maxHealth = 40;
int minHealth = 30;
Game.enemyHealth = ThreadLocalRandom.current().nextInt(minHealth, maxHealth + 1);
int maxAttackDamage = 20;
int minAttackDamage = 15;
Game.enemyAttackDamage = ThreadLocalRandom.current().nextInt(minAttackDamage, maxAttackDamage + 1);
game.enemy = enemies;
}
}
}
最终文件名为Items and heres，代码为：
public class Items {
static int healthPotion;
static int ironShard;
static int sharpWoodenSword;
static int averageWoodenSword;
static int dullWoodenSword;
}
答案 0 :(得分：3)
在这个方法的敌人课程中：
getEnemy()
创建一个新的Game对象。
因此，在执行此操作时，新的Game对象将创建一个新的Enemy对象，该对象将创建一个新的Game对象，该对象将永远创建一个新的Enemy对象。
如果是这样，解决方案不是这样做，而是将当前的Game实例传递给 Enemy类，而不是创建一个新的Game实例。
更改敌人，以便它获得单个有效的游戏对象（如果有的话）。改变这个：
public class Enemies {
public void getEnemy() {
Random rand = new Random();
String[] list = {"Skeleton", "Zombie"};
Game game = new Game();
到此：
public class Enemies {
private Game game; // variable to hold Game reference:
public Enemies(Game game) {
this.game = game; // set the instance
}
public void getEnemy() {
Random rand = new Random();
String[] list = {"Skeleton", "Zombie"};
// Game game = new Game(); // no longer need this
然后当你创建敌人时，传入this游戏实例：
Enemies newEnemy = new Enemies(this);
同样如评论中所述，while循环应该存在，因为它们完全违背事件驱动的编码实践。你的第一份工作应该是完全摆脱它们，而是编写代码来对事件作出反应。
