java - 如何在用户退出后重新启动我的游戏(Libgdx)

Question

在我的 libgdx 游戏中，它按照我想要的方式运行，但是当我退出游戏时，它从我之前所在的位置开始，我希望它重新启动。代码如下。

package com.me.fixGame;

import java.util.Random;









import com.badlogic.gdx.ApplicationListener;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.Input.Keys;
import com.badlogic.gdx.graphics.GL10;
import com.badlogic.gdx.graphics.Texture;


import com.badlogic.gdx.graphics.g2d.BitmapFont;
import com.badlogic.gdx.graphics.g2d.SpriteBatch;
import com.badlogic.gdx.graphics.g2d.TextureRegion;
import com.badlogic.gdx.math.Rectangle;
import com.badlogic.gdx.math.Vector2;
//import com.badlogic.gdx.scenes.scene2d.Stage;
import com.badlogic.gdx.scenes.scene2d.ui.Table;
import com.badlogic.gdx.utils.Scaling;
import com.sun.jmx.snmp.tasks.Task;


public class fixGame implements ApplicationListener {
    SpriteBatch batch;
    SpriteBatch spriteBatch;
    Texture trash; 
    Texture paper;
    SpriteBatch spritebatch;
    Vector2 position;
    Vector2 pas;
    boolean collide;
    boolean countMe=false;
    Vector2 size;
    Vector2 size2;
    Vector2 pos;
    Rectangle bounds;
    float posSpeed=30;
    Rectangle bounds2;
    float delay = 1; // seconds
boolean counted= false;
    int score = 3;
    //Texture Gogreen;
    String myScore;
    Texture background; 
    CharSequence str = "Lives left: 3"; // = myScore;
    CharSequence line = "Score: 0"; // = myScore;
    String myLife;
    int life=0;
    BitmapFont font;
    float x;
    float y;
    boolean collision = false;
    @Override
    public void create() {  

     //Gogreen = new Texture(Gdx.files.internal("data/gogreenNow.jpg"));
     background = new Texture(Gdx.files.internal("data/trash.png"));

     x= background.getWidth();
     y=background.getHeight();
        //float delaySeconds = 1;
        spriteBatch = new SpriteBatch();
    trash = new Texture(Gdx.files.internal("data/trash.png"));
    paper = new Texture(Gdx.files.internal("data/paper1.jpg"));
    position = new Vector2(100, 50);
    pos = new Vector2(54, 14);
    batch = new SpriteBatch();
    BitmapFont font = new BitmapFont();

    size2 = new Vector2(trash.getWidth() ,trash.getHeight() );
    //size2.y = trash.getHeight();
    //size2.x = trash.getWidth();
    size = new Vector2(paper.getWidth() ,paper.getHeight());

    bounds= new Rectangle(pos.x, pos.y, size.x, size.y);
    bounds2= new Rectangle(position.x, position.y, size2.x, size2.y);

    }

    @Override
    public void dispose() {

    }
    public void update(){
        bounds.set(pos.x, pos.y, size.x, size.y);
        bounds2.set(position.x, position.y, size2.x, size2.y);
        float pos1=Gdx.input.getAccelerometerX();
        //if(pos1<0)
        //  pos1=(-1)*pos1;
        position.x = position.x - 5*pos1;
    }




    @Override
    public void render() {
        if(bounds.overlaps(bounds2)){
            collision=true; 
            counted=true;
        }else{
            collision=false;
        }

        if(collision==true){

        } 
        if(pos.y<640){
            counted=false;
        } else if(pos.y > 640 && collision==false && counted==false){
            counted=true;
            score= score-1;
            myScore = "Lives left: " + score;
            str = myScore;
        }



        if(bounds.overlaps(bounds2)){

            countMe=true;
            life= life+50;
            myLife = "Score: " + life;
            line = myLife;
        }


        if(position.x<0){
            position.x= position.x+11;
        }
        if(position.x>425){
            position.x= position.x-11;
        }


          update();
            Gdx.gl.glClearColor(1, 1, 1, 1);
        Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
        pos.y=pos.y-posSpeed;
        //posSpeed = posSpeed+(2/3);
        if(pos.y<0){
            pos.y = 700;
            Random randomGenerator = new Random();
              pos.x = randomGenerator.nextInt(500);
        }
        BitmapFont font = new BitmapFont();


        batch.begin();

         batch.draw(background, 0, 0, Gdx.graphics.getWidth(), Gdx.graphics.getHeight());
         if (!collision) {
                batch.draw(paper, pos.x, pos.y);

                }

        //batch.draw(paper, pos.x, pos.y);
        batch.draw(trash, position.x, position.y);
        font.setScale(3);

        font.setColor(0.0f, 0.0f, 1.0f,1.0f);
        font.draw(batch, str, 300,900);
        font.draw(batch, line, 300, 950);
                batch.end();
                font.dispose();     
    }

     @Override  
    public void resize(int width, int height) {

    }

    @Override
    public void pause() {
    }

    @Override
    public void resume() {
    }
}

我在网上找了半天也没找到。有人有答案吗？提前感谢任何帮助。

Answer 1

你说的是台式机还是 Android？

假设您谈论的是 Android，当用户退出游戏时，将调用 pause() 函数。当用户返回游戏时，将调用 resume() 函数。

我敢打赌，如果您在退出和继续游戏之间运行了一些其他应用程序，您的游戏将会“重置”。通常人们将游戏状态保存在 pause() 中，然后在 resume() 中加载它，但对于您的情况，听起来您只想每次都重置它。

如果以上所有情况对您来说都是正确的，只需在 resume() 函数中重置游戏状态即可。
