随机位置持续时间libgdx

Question

我试图用libgdx做一个游戏，但有一个问题。我已经找得很好了，但我找不到解决办法。

public class MainScreen implements Screen {

SpriteBatch batch;
private Texture carte;
private Texture mario;
private Array<Rectangle>foret;
private Animation animation;
private float time;
private Rectangle mari;
private Vector2 position;
private Rectangle mickey ; 
Game game;
public MainScreen(Game game) {
    this.game = game;
    batch = new SpriteBatch();
    carte = new Texture(Gdx.files.internal("foret.png"));

    animation = new Animation(3/3f , new TextureRegion(new Texture("mario1.png")) , new TextureRegion(new Texture("mario2.png")) , new TextureRegion(new Texture("mario3.png")));

    foret = new Array<Rectangle>();

}


public void carte(){
    foret = new Array<Rectangle>();
    for(int i =0 ; i<7 ; i++){
        for(int j =0 ; j<7 ; j++){
            Rectangle fore = new Rectangle();
            fore.x = (i*100)+100;
            fore.y = (j*50)+20 ;
            fore.width = 64;
            fore.height = 64;
            foret.add(fore);
            batch.draw(carte ,fore.x , fore.y , 64 , 64 );
        }
    }
}
public Rectangle depMarioRandom(){
    foret = new Array<Rectangle>();
    for(int i =0 ; i<7 ; i++){
        for(int j =0 ; j<7 ; j++){
            Rectangle fore = new Rectangle();
            fore.x = (i*100)+100;
            fore.y = (j*50)+20 ;
            fore.width = 64;
            fore.height = 64;
            foret.add(fore);
        }}
    int random = (int) ( Math.random() * foret.size );
    Rectangle randomX = foret.get(random);
     return randomX;

}

@Override
public void show() {


}
@Override
public void render(float delta) {

    Gdx.gl.glClearColor(1, 1, 0, 1);
    Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);


    this.mari = depMario();
    time += delta;
    Vector2 position = new Vector2(this.mari.x, this.mari.y);

      // i try te do a copy and scaling whith time but it doesn't work

    position.cpy().scl(time);

    batch.begin();
    carte();

    batch.draw(animation.getKeyFrame(time), position.x, position.y, 64, 64);
    animation.setPlayMode(Animation.PlayMode.LOOP);


    batch.end();
}
@Override
public void resize(int width, int height) {
}
@Override
public void pause() {
}
@Override
public void resume() {
}
@Override
public void hide() {
}
@Override
public void dispose() {

}
}

我已经读过你的问题好几次了，这是我所理解的

你想让你的心脏有一秒钟的rondom中毒，你可以这样做

 counterTime += Gdx.graphic.getDeltaTime();
        time += delta;
        if(counterTime > 1 ) {// each second ==> one call to position random
            // putting the random position here
            position = new Vector2(this.mari.x, this.mari.y);
            counterTime = 0; // reset to 0;
        }

    // do not scall anything


    batch.begin();
    carte();

但是您只需要在create（）方法中第一次初始化位置
