java - 如何为两个玩家掷骰子编程

Question

(处理)代码没有返回我想要的结果。基本上，有两个玩家，每个玩家轮流掷骰子。这些值应分别存储在变量“p1diceroll”和“p2diceroll”中。它将比较两个值，并根据谁滚得更高来发布谁将先进行。

void setup(){
    size (100,100);
    background(200,200,200); 
    println("press l to roll the die!");
}

void draw() {
      if(keyPressed)
          keyPressed();
      noLoop();
}

void keyPressed(){
    int p1diceroll=0;
    int p2diceroll=0;

    if (key == 'l') {
        double rand1 = Math.random();
        double rand2 = rand1*6;
        double rand3 = rand2 +1;
        p1diceroll = (int)rand3;

        println("You rolled a " + p1diceroll + "!"); 
        println("player 1! press 'a' to roll");
    }

    if (key == 'a') {
        double rand11 = Math.random();
        double rand22 = rand11*6;
        double rand33 = rand22 +1;
        p2diceroll = (int)rand33;

        println("You rolled a " + p2diceroll + "!");


        if (p2diceroll>p1diceroll) {
            System.out.println("player 2  rolled higher!. They go first. "); 
        } else if (p2diceroll==p1diceroll) {
            System.out.println("It's a tie! player 1 goes first by default." ); 
        } else {
          println("player 1 rolled higher! They go first.");
        }
    }
}

我希望输出是“玩家 2 滚得更高!他们先走。”、“平局!默认情况下，玩家 1 走在前面。”或“玩家 1 滚得更高。他们先走。”

Answer 1

除了 A.A 的回答之外，我还提供了一些处理选项:

1. random() (例如 println((int)random(1,7)); (转换为 int 相当于 println(floor(random(1,7)) ); 这会将 float 降至 1-6 之间。
2. randomGaussian()玩 distribution is closer to a dice roll 可能会很有趣
3. noise()会给你很多选择，特别是与 noiseSeed() 一起使用和 noiseDetail()

我还注意到每次按下该键时每个玩家的骰子值都会重置。我不能 100% 确定这就是您的意图，因为这两个值之一始终为 0。

这是使用 random() 和调试文本的代码调整版本:

int p1diceroll=0;
int p2diceroll=0;

String result = "";

void setup(){
    size (120,120);
    background(200,200,200); 
    println("press l to roll the die!");
}

void draw() {
  background(0);
  text("press 'l' for p1"
      +"\npress 'a' for p2"
      +"\n\np1diceroll: " + p1diceroll
      +"\np2diceroll: " + p2diceroll
      +"\n\n"+result,5,15);
}

void keyPressed(){
    if (key == 'l') {
        p1diceroll = (int)random(1,7);

        println("You(p1) rolled a " + p1diceroll + "!"); 
        println("player 2! press 'a' to roll");
    }

    if (key == 'a') {
        p2diceroll = (int)random(1,7);

        println("You(p2) rolled a " + p2diceroll + "!");

        if (p2diceroll > p1diceroll) {
          println("player 2  rolled higher(" + p2diceroll + " > " + p1diceroll + ")!. They go first. ");
          result = "player 2\ngoes first";
        } else if (p2diceroll == p1diceroll) {
          println("It's a tie! player 1 goes first by default." );
          result = "tie! player 1\ngoes first";
        } else {
          println("player 1 rolled higher(" + p1diceroll + " > " + p2diceroll + ")! They go first.");
          result = "player 1\ngoes first";
        }
    }
}
