Libgdx - Animation only plays for 1 second inside if statement - libgdx

Question

Basically, when the ball hits the top wall. I want it to make some lightning strike animation, but the animation only last around 1 second.
if(ball.getY() + ball.getHeight() > topWall.getY()) {
game.getBatch().draw(animation.getKeyFrame(timepassed, false), ball.getX(), ball.getY() + ball.getHeight(), 0, 0, leftWall.getWidth(), leftWall.getHeight() * -1, 1, 1, 0f);
LightingStrikeRectArrayList.add(new Rectangle(ball.getX(), Apm.HEIGHT - ball.getY() + ball.getHeight() / 2, topWall.getWidth(), topWall.getHeight()));
for (Rectangle rect : LightingStrikeRectArrayList) {
if (rect.overlaps(playerHitbox)) {
this.game.setScreen(new GameScreen(this.game));
}
}
if(!(LightingStrikeRectArrayList.isEmpty() && animation.isAnimationFinished(timepassed))) {
LightingStrikeRectArrayList.remove(0);
}
ball.reverseDirectionY();
}

Answer 1

The problem seems to be that you only draw the animation as long as the ball is on the top. When the ball moves back down the animation stops.
If you set a boolean variable that indicates, that the ball was touching the top wall, and draw the animation as long as this flag is set, it will continue to be drawn event if the ball moves back down.
A solution could look similar to this:
// create a global variable somewhere in the class, to store the flag
private boolean ballTouchedTopWall = false;
public void processGame() {
//...
if(ball.getY() + ball.getHeight() > topWall.getY()) {
// set the flag instead of drawing the animation
ballTouchedTopWall = true;
LightingStrikeRectArrayList.add(new Rectangle(ball.getX(), Apm.HEIGHT - ball.getY() + ball.getHeight() / 2, topWall.getWidth(), topWall.getHeight()));
for (Rectangle rect : LightingStrikeRectArrayList) {
if (rect.overlaps(playerHitbox)) {
this.game.setScreen(new GameScreen(this.game));
}
}
if(!(LightingStrikeRectArrayList.isEmpty() && animation.isAnimationFinished(timepassed))) {
LightingStrikeRectArrayList.remove(0);
}
ball.reverseDirectionY();
}
if (ballTouchedTopWall) {
game.getBatch().draw(animation.getKeyFrame(timepassed, false), ball.getX(), ball.getY() + ball.getHeight(), 0, 0, leftWall.getWidth(), leftWall.getHeight() * -1, 1, 1, 0f);
// reset the flag when the animation ends
if (animation.isAnimationFinished(timepassed)) {
ballTouchedTopWall = false;
}
}
}
