Create a Java Tower Defence game by Kaarin Gaming

Sobre este curso

Turn Java fundamentals into a complete, playable tower defense game by building a project that feels like a real product, not a throwaway demo. In this free online course, you will create a grid-based game using Java and Swing, learning how to organize code so it stays maintainable as features grow. Instead of focusing on isolated snippets, you will work through the practical decisions every game developer faces: rendering sprites smoothly, reacting to player input accurately, and keeping the experience consistent across different machines.

You will develop a solid game foundation with a reliable loop structure and clean scene handling, so menus, settings, editing, and gameplay behave predictably. Along the way, you will tackle common problems that trip up new developers, such as coordinate offsets with mouse input, drawing and rotating sprites correctly, and animating tiles without creating messy, duplicated asset definitions. By working directly with a tile grid, you will see how data structures and rendering logic connect, which makes your project easier to extend.

A major milestone is bringing the world to life with enemies that follow paths across the map. You will implement and refine path logic so movement and turns look correct, while keeping positions precise for smooth motion. From there, you will add towers with placement rules, prevent invalid or overlapping builds, and create combat interactions that feel responsive. Projectiles, range indicators, damage, health bars, explosions, and slow effects are introduced in a way that highlights reusable architecture rather than one-off hacks.

To make the game feel complete, you will add wave progression, an economy with income and spending choices, upgrades and selling logic, pause and game-over behavior, and sensible replay handling. You will also implement saving and loading levels and learn what changes are needed to package and run the game outside the IDE. By the end, you will have a working Java tower defense game and the confidence to evolve it into your own original version with new enemies, towers, levels, and balancing.
