Mastering SOLID Principles in Unity Game Development

Master the single responsibility principle in Unity by splitting a player script into separate classes for movement, attack, and sound, reducing spaghetti code and improving modular design.

Refactor a monolithic tank controller into modular movement, rotation, and firing in Unity using SRP, comparing before and after in a 2D project.

Explain the open closed principle (OCP) and extend a tank fire system with normal and burst modes using a common I fire mode interface, preserving existing code.

Explore the open closed principle by adding normal and burst fire modes to tank fire script in Unity, highlighting a growing switch based design and prep for an OCP solution.

Explore how to implement the open-closed principle (OCP) in Unity by designing a fire mode system with an interface, enabling normal and burst modes for a tank.

Discover how the Liskov substitution principle uses a common tank engine base with start and stop methods to replace light, medium, and heavy engines without breaking behavior in Unity.

Explore implementing tank engines without LSP, then refine with the Liskov substitution principle to ensure consistent start and stop engine behavior across light, medium, and heavy tanks in Unity.

Refactor the tank system to follow the Liskov substitution principle by using a TankEngine superclass and overriding start engine and stop engine in light, medium, and heavy tank engines.

the interface segregation principle shows how to avoid forcing tanks to implement unused movement methods by splitting movement into forward and backward interfaces.

Implement the interface segregation principle in unity by creating forward and backward movement interfaces for light, medium, and heavy tanks, then verify movement behavior across tank types.

Apply the dependency inversion principle to decouple high level modules from low level bullet implementations by using abstractions and interfaces like the I projectile interface.

Learn to apply the dependency inversion principle in unity by decoupling tank firing from concrete shells through an IProjectile interface and light, medium, and heavy projectile implementations.

Visualize a Unity game project with two tanks, light and heavy, drones, scoring, and UI screens, then implement movement, firing, drone interaction, sound, and modular interfaces.

Import five Unity packages, organize folders, and configure sorting layers—from ground to enemy—to assemble a playable 2D tank game scene in Unity.

Apply interface segregation and dependency inversion to implement tank movement in Unity. Build light and heavy tanks with forward and backward controls and mouse-based gun rotation.

Implement a modular tank fire system in Unity by applying the open closed principle with an i projectile interface and distinct light and heavy shell projectiles.

Toggle between light and heavy tanks with the tank selector script by pressing L or H, starting or stopping the engine and disabling movement, rotation, and firing.

Implement a health system class for tanks in Unity using IDamageable to take damage, update a world-space health bar, and mark tanks inoperable when health hits zero.

Configure and spawn drones in Unity 2D by implementing the move forward drone script and a spawner that instantiates drone prefabs at random right-edge points, with proper layers and colliders.

Add a drone health script implementing IDamageable and destroy drones on take damage; enable projectile collisions via layers and 2D colliders, apply damage, and destroy shells off screen.

Declare and fire game events with the observer pattern in Unity, such as on game started, on game over, on tank fired, on tank damaged, and on drone damaged.

Create a dedicated sound manager in Unity that follows the single responsibility principle, subscribing to projectile fired, tank damaged, and drone damaged events to play corresponding audio clips.

Manage the home, gameplay, and game over screens with the UI manager, updating the gameplay score and final score on game over while responding to game start and end events.

Create a game manager that tracks all tank engine statuses, reacts to tank damaged events, and triggers game over to drive the UI manager.

Add rockets and laser projectiles, introduce a medium tank with different weaponry, and diversify drones with varied speeds and spawner timing to raise difficulty; apply solid principles with modular code.
