Overview

The ScoreScreen class displays the player’s final score at the end of a game session. It provides a simple UI overlay with the score and a button to return to the main menu. Package: com.pmm.games.screens Implements: Screen (libGDX)

​
Purpose

This screen serves as the game-over screen, showing players their final score and providing navigation back to the main menu. It uses Scene2D for UI management and creates a semi-transparent overlay to display the score information.

​
Constructor

​
ScoreScreen

public ScoreScreen(int score)
Creates a new score screen instance. Parameters:
  • score (int) - The final score to display to the player
Example: 
// Create a score screen showing player achieved 1500 points
ScoreScreen scoreScreen = new ScoreScreen(1500);
game.setScreen(scoreScreen);

​
Methods

​
show

@Override
public void show()
Initializes and configures the user interface elements. This method:
  • Creates a semi-transparent background (300x150 pixels, yellow tint with 30% opacity)
  • Displays the score with label “Tu puntuación: ” at 2x font scale
  • Adds a “MENÚ” button to return to the main menu
  • Loads UI skin from skins/uiskin.json
Called automatically when the screen becomes active.

​
render

@Override
public void render(float delta)
Renders the screen each frame. Parameters:
  • delta (float) - Time elapsed since last frame in seconds

​
resize

@Override
public void resize(int width, int height)
Adjusts the UI when window size changes. Parameters:
  • width (int) - New window width
  • height (int) - New window height

​
isShowScoreScreen

public boolean isShowScoreScreen()
Checks whether the score screen should remain visible. Returns: true if screen should continue showing, false if it should close (user clicked menu button) Example: 
// In game render loop
if (!scoreScreen.isShowScoreScreen()) {
    game.setScreen(new MainMenuScreen());
}

​
pause / resume / hide

@Override
public void pause()
@Override
public void resume()
@Override
public void hide()
Lifecycle methods with no specific implementation for this screen.

​
dispose

@Override
public void dispose()
Releases all resources used by the screen, specifically the Scene2D stage. Important: Always call this method when the screen is no longer needed to prevent memory leaks.

​
UI Components

The ScoreScreen creates the following UI elements:
  1. Background: Semi-transparent yellow rectangle (300x150px, 30% opacity)
  2. Score Label: Displays “Tu puntuación: ” with 2x font scaling
  3. Menu Button: “MENÚ” button (100x30px) that sets showScoreScreen to false when clicked

​
Integration with Game

The ScoreScreen is typically shown when the game ends. The calling code should:
  1. Create the ScoreScreen with the final score
  2. Set it as the active screen
  3. Monitor isShowScoreScreen() to detect when user wants to return to menu
  4. Dispose the screen when transitioning away
Example integration: 
// In GameScreen when game ends
int finalScore = player.getScore();
ScoreScreen scoreScreen = new ScoreScreen(finalScore);
game.setScreen(scoreScreen);

// In main game loop
if (game.getScreen() instanceof ScoreScreen) {
    ScoreScreen current = (ScoreScreen) game.getScreen();
    if (!current.isShowScoreScreen()) {
        current.dispose();
        game.setScreen(new MainMenuScreen());
    }
}

​
Dependencies

  • libGDX Core: For Screen interface and graphics
  • Scene2D: For UI management (Stage, Table, Label, TextButton)
  • UI Skin: Requires skins/uiskin.json file in assets

​
Notes

  • The screen displays text in Spanish (“Tu puntuación”, “MENÚ”)
  • Uses a semi-transparent overlay that doesn’t obscure the underlying game screen
  • Input handling is automatically set to the stage in the constructor
  • The background is created programmatically using Pixmap for flexibility
