我相对较新的java和一个项目我正在制作一个最多有4个玩家的游戏，但最初它会询问有多少玩家，所以我不需要主游戏中的所有4个玩家的脚本。我试图让每个玩家都成为一种方法，并且根据玩家的数量，这将是有多少玩家的剧本。
基本上我不知道如何使用if语句中的一个命令来运行玩家的方法。
如果声明：
if (playerAmount == 1)
{
run (player1); // this was my attempt to run the methods xD
}
else if (playerAmount == 2)
{
run (player1);
run (player2); // this was my attempt to run the methods xD
}
else if (playerAmount == 3)
{
run (player1);
run (player2);
run (player3); // this was my attempt to run the methods xD
}
else if (playerAmount == 4)
{
run (player1);
run (player2);
run (player3);
run (player4); // this was my attempt to run the methods xD
}
方法（每个玩家都有一个，这只适用于玩家1）：
public static void player1()
{
Scanner keyboard = new Scanner (System.in);
int p1space = 0;
int p1health = 100;
int p1dollars = 0;
int rollValue = 0;
int rollDie = (int) (6*Math.random()+1);
System.out.println ("Player 1, Please Enter Your Name");
String p1name = keyboard.nextLine();
keyboard.nextLine();
System.out.println ("Would you like a tutorial on how to play? (type yes or no)");
String tutorial = keyboard.nextLine();
if ((tutorial .equals ("yes")))
{
System.out.println ("Okay, first the game will have you type roll to roll your die.");
System.out.println ("After that, depending on what number you got on your die, your character will move that far.");
System.out.println ("Certain spaces have traps and things to set you back so watch out! There are also spaces that give you bonuses such as extra health.");
System.out.println ("That should be enough for you to play. Have Fun! :)");
}
while (p1health > 0)
{
System.out.println (p1name + " it's your turn!");
System.out.println ("Type roll to roll your die");
String roll = keyboard.nextLine();
if (roll .equals ("roll"))
{
rollValue = rollDie;
p1space = p1space + rollValue;
if (p1space == 0)
{
System.out.println ("START");
}
else if (p1space == 1)
{
System.out.println ("SPACE 1");
}

System.out.println ("You found a med pack, +50 Health!");
p1health = p1health +50;

{
System.out.println ("SPACE 3");
System.out.println ("You find a jetpack, move forward one space");
p1space = p1space +1;

System.out.println ("You are kidnapped, move back two spaces.");

让玩家成为一个班级。并且类具有诸如播放器名称和诸如startGame之类的方法之类的属性。此外，您还可以向玩家提供玩家选择的数量，并根据需要创建玩家对象。

我不确定这是否是您需要的，但您可以考虑使用可运行的界面
private Runnable myRunnable = new Runnable() {
public void run() {
// do your stuff here
}
};
然后你可以像这样运行它
myRunnable.run();

直接回答你的问题。由于您的方法名称为player1。要调用方法，请编写方法名称后跟一对括号：
myMethod();
所以你的代码应该是这样的：
if (playerAmount == 1)
{
player1(); //run method for player1
}
您可能已经意识到所有方法中都有大量的代码重复（player1（），player2（），player3（）和player4（））。您可能想学习如何将参数传递给方法。这样，您只需要实现一次：
public static void player(int playerNo){
}
知道如何使用方法之后。您可能还想看看Java类，您可以将每个播放器实际实现为对象而不是方法：
class Player{
public void runScript(){
}
}
