Libgdx texture on key input too fast

Question

I want to draw a texture when I press a key. I'm using isKeyJustPressed() method and because of this , the texture appears and dissapears really fast. How can I slow it down a bit, so I can see it appear?

Answer 1

Are you drawing the texture like this?

public void render() {
    ...
    batch.begin();
    ...
    if(isKeyJustPressed...) {
        texture.draw()...
    }
    ...
    batch.end();
    ...
}

If so your texture will be drawn only for just one frame.

If this is the problem:

float timeRemaining = 0f; // in seconds
public void render() {
    ...
    batch.begin();
    ...
    if(isKeyJustPressed...) {
        timeRemaining = 5; // will show the texture for 5 seconds
    }
    if (timeRemaining>0) {
        timeRemaining -= Gdx.graphics.getDeltaTime();
        texture.draw()...
    }
    ...
    batch.end();
    ...
}

Also I would highly suggest that you go through this tutorials before jumping into making games.
