Java Basic Memory Matching Game
提问by William White
I am trying to code a 4x4 memory matching game that has 8 identical number pairs. All face down cards are marked by an asterisk. Then the user inputs (1,1) and (1,2) as a guess and if correct they remain face up and the game continues.
我正在尝试编写一个具有 8 个相同数字对的 4x4 内存匹配游戏。所有面朝下的卡片都标有星号。然后用户输入 (1,1) 和 (1,2) 作为猜测，如果正确，它们保持面朝上，游戏继续。
My Problem: I have most of the code complete however my method gamewhich runs the game I cannot figure out how to set it up. Any advice would be appreciated.
我的问题：我有但是大部分的代码完成我的方法的游戏，其运行游戏，我无法弄清楚如何设置它。任何意见，将不胜感激。
My Code:
我的代码：
//Welcome Prompt
System.out.println("Welcome to the memory matching game!");
System.out.println("Enter the card coordinate for each card when promted to.");
System.out.println("For Example, 11 = Card 1 and 12 = Card 2.\n\n");
board();
}
//print the board
public static void board() {
int[][] cards = new int[4][4];
boolean upDown[][] = new boolean[4][4];
cards = randomizer(); //Shuffle cards
System.out.println(" 1 2 3 4 ");
System.out.println("---+---------");
for (int i = 0; i < 4; i++) {
System.out.print(" " + (i + 1) + " | ");
for (int a = 0; a < 4; a++) {
System.out.print("* ");
upDown[i][a] = false;
}
System.out.println();
}
System.out.println();
game(upDown, cards); // calls the game
}
public static int[][] randomizer() {
int num[] = {1, 2, 3, 4, 5, 6, 7, 8, 1, 2, 3, 4, 5, 6, 7, 8};
int cards[][] = new int[4][4];
Random random = new Random();
int temp, t;
for (int j = 0; j <= 20; j++) {
for (int x = 0; x < 16; x++) { //Randomize the card order
t = random.nextInt(1000) % 15;
temp = num[x];
num[x] = num[t];
num[t] = temp;
}
t = 0;

{
for (int s = 0; s < 4; s++) {

}
}
}
return cards;

This is very basic. But it shows the basic idea of how to run the game. Top left = "11", Bottom right = "44". You can clean it up as an exercise (including static references are passed as method arguments, checking that input will not cause array out of bounds errors, etc)
这是非常基本的。但它显示了如何运行游戏的基本思想。左上角 =“11”，右下角 =“44”。您可以将其清理作为练习（包括静态引用作为方法参数传递，检查输入不会导致数组越界错误等）
