Learn to create 2D game with unity and C#

Create a simple 2d game movement system using a state machine with idle and moving states, implementing enter, exit, and update methods to manage input and rigidbody velocity.

Refactor the 2D Unity game to keep a continuous x input, add a grounded check and jump state, and introduce a fall state with transitions to idle and moving.

Design a more varied level in Unity using a tile set and tile palette. Import assets, configure the sprite editor to 24×24, and organize tiles for the level.

Import background images, assign sorting layers and order in layer to place them behind the game, and create 2D physics materials with zero friction.

Implement a Unity enemy AI using a state machine with idle and patrol moving states, driven by idle and patrol timers, and layer collision settings to prevent player collisions.

Implement a horizontal wall check and ledge detection using a raycast to flip the enemy when a wall or ledge is ahead, preventing forward movement off edges.

Implement a two-dimensional attack system in Unity using a circle check, attack radius, and overlap circle to detect and damage enemies, with gizmos and animation events guiding frame-specific hits.

Create a singleton to reference the player, measure distance and direction to trigger a battle state, and move and flip the enemy toward the player when in range.

Create an enemy attack by importing an attack animation, setting an attack range and attack state in the animator, and using Physics 2D overlap circle checks to hit the player.

Build a Unity stat system with a base value, current value, and modifiers, applying it to health and attack power, and implement take and deal damage.

Build a Unity inventory UI with a grid layout for slots, icons, and item counts. Use a reusable item UI and inventory manager to update the display.

Learn to build a responsive inventory user interface in Unity by activating the panel, wiring item icons, names, and descriptions with a description manager, and previewing item data on hover.

Learn to use inventory items in Unity that modify health or attack via modifiers and increasers, apply item effects to player stats, remove used items, and refresh the UI.
