Learn To Code By Making a 2D Platformer in Unity

Learn to build a Unity camera controller that follows the player with an adjustable ahead offset, using a target position and smooth movement to avoid abrupt camera flips.

Disable anti-aliasing and isotropic textures to reduce on-screen lines. Extend tile edges in the sprite sheet and replace the asset to remove tiny gaps.

Set up a kill plane in Unity using a wide 2D box collider as a trigger beneath the camera to reset the player by deactivating the object on trigger entry.

Master delaying respawn in a Unity 2D platformer by implementing coroutines in the level manager, deactivating the player, and using yield return WaitForSeconds to time respawns.

Create a destroy script with a public lifetime, decrement it by time.deltaTime in update, and destroy the object when the lifetime reaches zero to prevent memory clutter.

Learn to build a moving platform in Unity, define start and end points, move between them with MoveTowards, set up colliders and a prefab, and script player carrying behavior.

Create a collectible system with coin prefabs and a trigger collider, where a coin script disappears on collection and a level manager tracks coin totals and values.

Create and display a coin counter using Unity's UI text, link it to the level manager, anchor it to the top-left corner, and update the text as coins are collected.

Learn to implement health in the UI by using heart sprites, creating a heart holder under the canvas, and syncing three hearts to the player via the level manager.

Implement a Unity health system by linking heart sprites to a level manager, tracking max and current health, applying damage, and updating visuals.

Implement a health UI in a Unity 2D platformer using a switch statement to update a heart meter and sprites.

Learn to implement a 2d spider enemy in unity that activates when visible, uses rigidbody2d velocity for leftward movement, deals damage on contact, and gets destroyed by a kill plane.

Activate the stompbox only when the player moves downward by checking velocity.y in the player control script, and reset enemies and coins on death to restore the world.

Create an array to store objects that need resetting. Populate it at start by finding objects of type reset, then deactivate them with setActive(false) and reset in a for loop.

Implement a Unity coin-based bonus life system that tracks a hidden coin bonus count, awards lives at a configurable threshold, and resets on death.

Add a coin pickup sound via the level manager rather than duplicating audio sources on each coin, and play the sound when coins or hearts are collected.
