Description

Are you ready to create your very own Tower Defense video game? Whether you're a beginner or an experienced developer, this comprehensive and standalone course will guide you step by step through building a complete game from scratch using Unity and C#.No experience with game development? No problem! I’ve included a crash course section specifically designed for complete beginners who have never touched Unity before. We'll get you on track in no time. In the main section, we’ll start slow and easy, so you can follow along comfortably as we build your skills and confidence.Throughout this course, you’ll learn how to setup:Enemy and Wave Management: Set up enemies with AI navigation, including movement, waypoints, and respawn mechanics. Implement wave systems with multiple waves, timers, and dynamic level changes to keep gameplay challenging.Diverse Enemy Types: Create a variety of enemies, including basic units, quick sprinters, swarm enemies, heavy tank with shields, stealth units with buffs, flying enemies, and two powerful bosses. All of that is designed to ensure you have plenty of practical examples to learn how to design and develop unique behaviors for your games.Build System: Create a robust build system for tower placement, unlockable towers, attack radius visualization, and interactive previews with hotkeys. Towers: Build and design towers with unique mechanics, including cannons, machine guns, lasers, drones, and more. Each tower introduces new mechanics and attack patterns to expand your skills.Target and Damage System: Build an advanced targeting system capable of prioritizing enemies based on progress, proximity, or surrounding groups, with dynamic switching for smarter gameplay.Level Creation and 3D Tile System: Create levels using a 3D tile-based system with custom editor tools, dynamic NavMesh updates, all build to make development faster and easier.Game Loop and Seamless Level Transitions: Build a smooth game loop with dynamic progression, seamless level transitions, and win/loss conditions to tie all systems together.UI Systems : Design a complete UI system with menus, in-game elements like health and currency, and animations such as fade-ins, button hovers, and shakes to enhance player interaction.Audio System: Set up an audio manager to control background music, sound effects, and volume settings, adding immersive audio to your game.Camera: Develop a dynamic camera with smooth movement, rotation, zoom, transitions, and screen shake effects. Post-Processing and Optimization: Enhance visuals with post-processing and optimize performance to maintain high FPS.By the end of this course, you won’t just have a completed tower defense game—you’ll have the skills and knowledge to create games with confidence. Maybe even publish them on Steam. Ready to turn your ideas into reality? Let’s make it happen. Enroll in my course today and begin your game dev journey!
