Libgdx 不断绘制纹理

Question

When my if-statement is true, I want to draw a Texture.

But the Texture is displayed for a second and directly disposes.

I wanted to ask if there is a way to stop the disposing and display the Texture even after the condition is fulfilled.

my render method:

@Override
public void render(float delta) {
    Gdx.gl.glClearColor(0, 0, 0, 1);
    Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);

    batch.begin();
    batch.draw(BackgroundImage, 0,0, BackgroundImage.getWidth(), BackgroundImage.getHeight());
    batch.end();

    // Kamera aktualisiert ihre Matrizen
    camera.update();

    // Dem SpriteBatch mitteilen , dass es das
    // Koordinatedsystem , welches von der Kamera erstellt wurde, benutzen soll
    batch.setProjectionMatrix(camera.combined);

    batch.begin();
    for (Rectangle raindrop : raindrops) {
        batch.draw(TropfenTexture, raindrop.x, raindrop.y);
    }
    bmf.setColor(1f, 1f, 1f, 1f);
    bmf.draw(batch, ScoreString, 10, 790);
    batch.end();

    GameSpeedup();

    Iterator<Rectangle> iter = raindrops.iterator();
    while (iter.hasNext()) {
        Rectangle raindrop = iter.next();
        raindrop.y -= 200 * Gdx.graphics.getDeltaTime();
        if (raindrop.y < 0)
            iter.remove();
        if (raindrop.overlaps(BoundsBottom)) {
            //dropSound.play();
            //game.setScreen(new GameOverScreen(game));
            //Gdx.input.vibrate(200);
            batch.begin();
            batch.draw(PfützeTexture, 0, 0);
            batch.end();
            }
        if (Gdx.input.justTouched()) {
            Vector3 tmp = new Vector3(Gdx.input.getX(), Gdx.input.getY(), 0);
            camera.unproject(tmp);
            if (raindrop.contains(tmp.x, tmp.y)) {
                CurrentScore++;
                ScoreString = "" + CurrentScore;
                if (dropSound.isPlaying())
                dropSound.stop();
                dropSound.play();
                iter.remove();
                if (raindrop.contains(tmp.x, tmp.y) && raindrop.overlaps(BoundsBottom)) {
                    CurrentScore++;
                    ScoreString = "" + CurrentScore;
                    dropSound.pause();
                    dropSound.play();
                    iter.remove();
                }
                }
            }
        }

        if (CurrentScore > Highscore){
            Highscore = CurrentScore;
            prefs.putInteger("highscore", Highscore);
            prefs.flush();
        }
    }

EDIT: clarified my question and added more code

Answer 1

In case i understand your question correctly you shouldnt be rendering an object by checking collisions. Instead render from arrays of your game entities.

1. Check collisions and remove add entities as need. in your case: remove raindrop, add splash.
2. render objects

3. update object positions

   if (raindrop.overlaps(BoundsBottom)) { waterRectangles.add(new WaterObject()); //maybe remove raindrop? } batch.start(); for(Rectangle waterObject: waterRectangles{ batch.draw(WaterTexture,waterObject.x,waterObject.y); } //same for raindrops batch.end(); //update positions

Hope this helps.
