Jump Game

A side-scrolling obstacle game built with Java and JavaFX. The player controls a character that must jump over incoming hurdles while a parallax background scrolls continuously.

Gameplay

• Press Up Arrow to jump over obstacles
• Score increases for each hurdle cleared
• Collision with a hurdle triggers Game Over
• Replay or return to the main menu from the Game Over screen

Features

• Parallax Scrolling — two background images loop seamlessly for infinite scrolling
• Collision Detection — real-time bounds intersection checks between character and hurdles
• Sound Effects — jump, duck, and game-over audio cues with background music
• Animated Intro — sequential scale transitions on menu elements
• Multiple Screens — intro menu, game screen, settings, credits, and game-over with replay
• Keyboard Controls — arrow key input handling for character movement

Architecture

├── HelloApplication.java   # Entry point — launches the intro screen
├── Introscreen.java        # Main menu with Play, Settings, Credits, Quit
├── GameScreen.java         # Core game loop — scrolling, hurdles, scoring, collision
├── settingScene.java       # Settings screen (placeholder)
└── creditScene.java        # Credits screen

Game Loop Design

The game uses JavaFX Timeline animations:

• Background movement — 30ms keyframes shift two tiled images left; when one exits the viewport it repositions behind the other
• Hurdle spawning — new obstacles appear every 5 seconds at the right edge and move left
• Jump mechanic — character Y-position shifts up instantly, then returns after 700ms

Setup

Prerequisites

• Java 17+
• Maven 3.8+
