在我的libgdx游戏中,它的功能是我想要的,但当我退出游戏时,它从我之前开始,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;

public class fixGame implements ApplicationListener {
    SpriteBatch batch;
    SpriteBatch spriteBatch;
    Texture trash; 
    Texture paper;
    SpriteBatch spritebatch;

    float delay = 1; // seconds

    int score = 3;
    //Texture Gogreen;
    String myScore;
    Texture background; 
    CharSequence str = "Lives left: 3"; // = myScore;

    @Override

     //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() {
    }
}

我在网上搜索过,但找不到任何东西。有人有什么答案吗? 任何帮助将提前感谢。

您在谈论桌面还是Android?

假设你在谈论Android,当用户退出游戏时,会调用pause()函数。当用户返回游戏时,调用resume()函数。

我敢打赌,如果您在退出和恢复游戏之间运行其他应用程序,您的游戏将“重置”。通常人们会在pause()中保存游戏状态,然后在resume()中加载它,但对于你的情况,听起来你只是想每次都重置它。

如果以上所有内容对您来说都是真的,只需在resume()函数中重置游戏状态。

答案 1 :(得分:0)

对于Android:如果用户按下“主页”按钮或呼叫即将进入,则会调用游戏pause()方法。如果用户在通话后返回,或在通常resume()被调用一段时间后返回。但是如果Android操作系统决定关闭你的应用程序,将调用create(),如果你不存储存储游戏,我相信它会重置游戏。 在您的情况下,用户没有退出游戏,而是通过按“主页”按钮“暂停”它。要重置游戏,您可以使用dispose()方法拨打pause(),然后只需关闭您的应用即可。如果你切换窗口或最小化应用程序,在桌面pause()上调用,据我所知。如果你不想在这种情况下关闭应用程序,你必须控制,如果它是桌面或Android。
