Unity 6 2D Platformer Course: Build a 2D Shooter Game

Learn to set up and create character animations in Unity, including running and jumping clips, adjust pixels per unit and sample rate, and wire them into the animator controller.

Create and connect idle, run, and jump animations in Unity, configure transitions with speed and is grounded, and drive them from the player script using Mathf.Abs for horizontal movement.

Create a playable environment in Unity using tile map system. Build ground and platforms with a tile palette, draw tiles, and refine collision with tile map and composite colliders.

Create a decorative environment using a decorations tile map and palette, placing non-collidable props such as crystal snow, grass, trees, and clouds.

Discover Unity 2D lighting by adjusting global light 2D, spotlights, inner and outer radii, falloff, color, freeform lights for ground and objects, and a player spotlight that follows the player.

Use Cinemachine to make the camera follow the player in a 2D platformer by installing the package, then configure a targeted camera with look ahead, smoothing, and dead zones.

Create a fully functional scoring system in Unity by collecting coins, using isTrigger colliders and tags, and updating coinScore with a MonoBehaviour script.

Add a canvas and a top-right score text in Unity. Set full HD resolution with scale mode and anchor to top-right, then wire a scoreText script to update the score.

Build a universal health system with spikes as obstacles, using box colliders and trigger colliders, and implement currentHealth, maxHealth, and damageAmount. Apply damage via onTriggerEnter2D and a DamagePlayer script.

Create a health bar UI in Unity with border and fill, then connect a slider to max health and current health via a health bar script.

Instantiate a damage effect at the player's position when damaged, using a public DamageEffect from the JMO assets folder (CartoonFX Remaster Free) for visual feedback and subtle camera shake.

Add an enemy by slicing a sprite sheet into multiple frames with the sprite editor, creating an enemy run animation, and placing it to patrol between two points.

Learn to implement a two-point enemy patrol with transform.position and Vector3.MoveTowards, using speed and time.deltaTime, plus a circle collider 2d trigger, sprite flip, and a damage script.

Set up a fire point, create a bullet prefab, and add shooting animation to fire bullets on mouse click, using instantiation and simple animator transitions.

Build a Unity 2D shooter bullet: move with rigidbody2d, zero gravity, destroy after two seconds; implement a coroutine-based shooting cooldown and basic enemy collision handling.

Fix the shooting direction by tracking the player's facing side with an isFacingRight boolean and a public accessor, then apply right or left bullet direction in the bullet script.

Add a damage effect by instantiating an explosion prefab at the enemy’s position when hit by a bullet, save prefab changes, and test the scene for a visible explosion.

Create a main menu, pause screen, and game over screen for a Unity 2D platformer, using canvas UI to load level one and manage start, pause, and quit.

Create a game over screen with menu and restart buttons activated when health reaches zero. The restart reloads current scene via scene management and unpauses the game across all levels.

Create an audio manager in Unity to organize sound effects and music. Assign audio sources for coin, damage, explosion, jump, and shoot, then play background music with sfx method.

Build universal level progression in a 2D Unity platformer by adding a level end with a collider and script that loads the next scene, using reusable prefabs.

Add a winning end scene with a congratulatory message and a main menu button, set up a UI canvas, and wire a script to load the main menu.
