Draw a sprite when a key is pressed in LibGDX

Question

I'm working with LibGDX. How can I draw a sprite when a key is pressed? I have tried with the following, but it doesn't seem to work.

if (Gdx.input.isKeyPressed(Input.Keys.X)) {
    batch.begin();
    sprite.draw(batch);
    batch.end();
}

Answer 1

You could have a boolean that you set to true when the key is pressed in your update method:

 boolean drawSprite;
 if (Gdx.input.isKeyPressed(Input.Keys.X)) {
      drawSprite = true;
 }

And then in your render method:

batch.begin();
if(drawSprite == true) {
 sprite.draw(batch);
}
batch.end();

Answer 2

I assume you are using Sprite class from libgdx and the sprite you created is working fine? And the only problem is you cannot show the sprite when a key is pressed.

@Override
public void update() {

    // the input is pressed once even you are still holding the button.
    if(Gdx.input.isJustKeyPressed(Input.Keys.X)) {
        sprite.setVisible(true);
    }

    batch.begin();
    sprite.draw(batch);
    batch.end();

}
