Question

我用Eclipse语言制作了一个Eclipse霓虹灯游戏，但是我想知道如何制作游戏，这样如果用户按下r或者她可以回到第一个屏幕，按下空格键开始。这是我的3个代码文件，如果你需要它来找出解决方案。

//This is the game file (main)

import processing.core.PApplet;

public class Game extends PApplet{

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        PApplet.main("Game");
    }

    James james1;
    Wall wall1;
    Wall wall2;
    Wall wall3;
    public void settings() {
        size(500, 700);
    }

    public void setup() {
        frameRate(40);
        james1 = new James(this, 250, 650, 50);
        wall1 = new Wall(this, 0);
        wall2 = new Wall(this, 250);
        wall3 = new Wall(this, -250);
    }

    public void draw() {
        if(key == ' ') {
        clear();
        background(0, 255, 255);

        boolean loser = wall1.col(james1.getX(), james1.getY()) || wall2.col(james1.getX(), james1.getY()) ||wall3.col(james1.getX(), james1.getY());
        james1.show();
        move();
        if (!loser){
            wall1.update();
            wall2.update();
            wall3.update();
        }
        else {
            reset();
        }
        wall1.display();
        wall2.display();
        wall3.display();
        }
        else {
            background(255, 0, 255);
            textSize(45);
            text("Press Space to Start!", 50, 350);
        }
    }

    public void reset() {
        clear();
        frameRate(0);
        textSize(40);
        text("You Lose, R to restart", 25, 550);
    }

    public void restart() {

    }

    public void move() {

        james1.setX(mouseX);

        if (mouseX <= 25) {
            james1.setX(25);
        }
        else if (mouseX >= 475) {
            james1.setX(475);
        }


    }



}


//This is the character file (James)

            if(ballX - 25 <= w || ballX+25 >= w+100) {

        return false;
    }


}

希望只有一个目标不会太长;）

将方法设置中的所有内容复制到方法重启，然后从方法设置中调用restart。

你得到这样的东西：

public void setup()
{
    restart();
}

public void restart()
{
    frameRate(40);
    james1 = new James(this, 250, 650, 50);
    wall1 = new Wall(this, 0);
    wall2 = new Wall(this, 250);
    wall3 = new Wall(this, -250);
}

现在只要你想让游戏重启就调用restart。在您的示例中：当用户按下“r”按钮时。

在游戏中，拥有一个处理这类事物的Map类确实是个好主意。
