HTML5-based Tower Defense Game
Project Title: HTML5-based Tower Defense Game using JavaScript and HTML
Project Summary
This project is a Tower Defense Game developed using HTML5 Canvas and JavaScript, where players place towers strategically to stop waves of enemies from reaching their destination. The game combines elements of strategy, timing, and resource management and is fully playable in a web browser.
Core Components
Game Map and Path
- A predefined path (or dynamic) along which enemies travel.
- Drawn on an HTML5 <canvas> or constructed with grid tiles.
Towers and Placement Logic
- Towers can be placed in allowed areas near the path.
- Each tower has attributes: range, damage, fire rate, and cost.
- Towers automatically detect and attack enemies within range.
Enemies and Waves
- Enemies spawn in waves and follow the path to the end.
- Each enemy has health, speed, and sometimes special abilities.
- Defeating enemies earns coins/points; surviving ones reduce player health.
Projectile and Collision System
- Towers shoot projectiles at enemies.
- Collision detection determines when a projectile hits and applies damage.
Game Loop and Rendering
- Uses requestAnimationFrame() for smooth real-time updates.
- Updates tower targeting, enemy movement, and visual animations each frame.
Scoring and Economy
- Players earn money from defeated enemies.
- Money is used to build new towers or upgrade existing ones.
Level Progression
- Multiple levels or increasing wave difficulty over time.
- Players win by surviving all waves or lose when too many enemies pass through.
Technologies Used
- JavaScript (core game logic and user interaction)
- HTML5 Canvas (visual rendering of the map, towers, enemies)
- CSS (styling menus, scoreboards, and in-game UI)
- Optional: localStorage for saving progress or high scores
Learning Outcomes
- Designing real-time game mechanics and canvas-based rendering
- Handling object-oriented structures for towers and enemies
- Collision detection and game physics basics
- Managing game state (waves, score, upgrades, health)
- Creating a responsive UI for browser gameplay
Possible Enhancements
- Add multiple tower types with unique effects (e.g., slow, area damage, poison)
- Enemy variety (flying enemies, bosses, fast runners)
- Tower upgrade system (level up damage, range, effects)
- Pause/play speed toggle and difficulty settings
- Sound effects and background music
- Map editor or custom wave designer
- Mobile responsiveness and touch controls
