[英]counter issue encountered with java
我正在做一個骰子游戲,規則是隨機擲2個骰子,如果第一次嘗試兩個骰子的總和為7或11,則用戶獲勝。 如果第一次嘗試總和為 2,3 或 12,則用戶輸了。 如果總和是 4,5,6,8,9,10,則該總和被設置為建立點並繼續擲骰子,直到總和與建立點匹配並且用戶獲勝,但是如果建立點是 7用戶輸了。
游戲進行了 3 次,並記錄了我贏了或輸了多少次。 但是,我無法完成該部分,不勝感激,我的代碼如下。
package roll;
import java.util.Random;
public class RandomSumGame {
boolean start;
int d1;
int d2;
int sum = d1 + d2;
int valuepoint;
String plus = "+";
public void play(int d1, int d2) {
int win = 0;
int loss = 0;
sum = d1 + d2;
for (;;) {
if (sum == 2 || sum == 3 || sum == 12) {
start = false;
loss++;
System.out.println(" = " + sum + ";you lose");
break;
} else if (sum == 7 || sum == 11) {
start = true;
win++;
System.out.println(" = " + sum + ";you win ");
break;
}
valuepoint = sum;
if (valuepoint == 4 || valuepoint == 5 || valuepoint == 6 || valuepoint == 8 || valuepoint == 9
|| valuepoint == 10) {
System.out.print(" = " + valuepoint + " you establish a value point " + valuepoint + "\n");
break;
}
}
for (;;) {
if (sum == 7 || sum == 11) {
break;
} else {
Random rand = new Random();
for (int i = 0; i < 1; i++) {
d1 = 1 + rand.nextInt(6);
int f1 = d1;
System.out.print("\t" + "-you rolled again " + d1 + " " + plus);
for (int x = 0; x < 1; x++) {
d2 = 1 + rand.nextInt(6);
int f2 = d2;
int loda = f1 + f2;
System.out.print(" " + d2 + " = " + loda + "\n");
}
}
sum = d1 + d2;
if (sum == valuepoint) {
start = true;
win++;
System.out.print("\t" + "you win!" + "\n");
break;
} else if (sum == 7) {
loss++;
start = false;
System.out.print("\t" + "you lose " + "\n");
break;
}
}
}
System.out.print("wins: " + win + "\n");
System.out.print("Losses:" + loss);
}
public void play() {
for (int x = 0; x < 3; x++) {
rolldice();
play(d1, d2);
System.out.print("\n");
}
}
public void rolldice() {
Random rand = new Random();
for (int i = 0; i < 1; i++) {
d1 = 1 + rand.nextInt(6);
System.out.print("You rolled " + d1 + " " + plus);
}
for (int i = 0; i < 1; i++) {
d2 = 1 + rand.nextInt(6);
System.out.print(" " + d2 + " ");
}
}
public static void main(String[] args) {
// TODO Auto-generated method stub
RandomSumGame Teet = new RandomSumGame();
RandomSumGame d1counter = new RandomSumGame();
RandomSumGame d2counter = new RandomSumGame();
Teet.play();
}
}
哪一部分你不能完成? 好像游戲運行了3次? 是輸贏的總數嗎? 要解決這個問題,您可以將“int win”和“int loss”移到 play 方法之外,使其成為全局變量。
編輯:如果您不想使用全局變量,您可以創建一個調用自身的方法(遞歸方法)
