Move a 2D player by updating Rigidbody2D.velocity using horizontal input, via a new Vector2 with x from input.GetAxis("Horizontal") multiplied by move speed; keep y unchanged in the update loop.

Create a new level scene, add ground, and import the blue wizard animations (idle, jump, walk) by dragging the folder into assets; set pixels per unit to 180.

Set up a 2D platformer player in Unity by renaming the character, adding box collider 2D and rigidbody 2D, adding ground with collider, and wiring horizontal movement via the script.

Implement a jump mechanic by using a jump button from the input manager to set the rigidbody velocity's y component with a jump force, while keeping the x velocity unchanged.

Set up two ground sensors and a ground layer to detect contact with the ground via overlap circle, allowing jumping only when grounded.

fix 2d player rotation and edge sticking in unity by freezing z rotation and applying a zero friction material, then implement direction changes by adjusting local scale with velocity.

Tackle a Unity challenge: wire the fire1 button to turn a square green and destroy a circle on left click using a public game object reference in a test scene.

Master basic Unity 2D mechanics by turning a game object's color to green on left-click and destroying an enemy, using a sprite renderer, GetComponent, and Fire1 input.

Explore how 2d animations work with sprites, build a simple player body, eyes, and legs in Unity, and create a looping idle animation using an animator controller.

Create a gun on the player and record a shooting animation with keyframes, set shooting as the default state in the animator controller, and remove test animations.

Add idle, walking, and jump animations to the player using existing sprites and an animator controller. Test the animations in play mode and adjust the sample rate to set tempo.

Learn to connect idle, walk, and jump in an animator controller, create speed and is grounded parameters, set transitions with conditions, and drive them from code using SetBool and SetFloat.

Create 2D environments in Unity using tile maps by slicing sprites into tiles, building ground and platforms with a tile palette, and drawing with the brush tool.

Create and refine a Unity 2D platformer environment by slicing tiles, assembling a tile palette, and applying tilemap and composite colliders with a kinematic ground.

Set up environment by changing ground geometry to outlines, adding a decorations grid with tile palettes, and adjusting collider offset and rendering order for better visuals, using Unity Asset Store.

Adjust the Village Props texture tileset's pixels per unit to resize the grid; set it to 30 or 28 to optimize space, then apply and reuse assets as needed.

Learn how to add and manage backgrounds in Unity for a 2d platformer, including removing stray colliders, using tiling for seamless backgrounds, and layering multiple images to build depth.

Set up a universal health system in Unity, using spikes as damage, create a player health script with current, max, and damage amount, initialize health, and hide player at zero.

Implement a damage system in a 2D Unity platformer by applying a damage player script to spikes, using OnTriggerEnter2D and the player health script’s deal damage.

Create a top-left health UI by adding a canvas, enabling scale with screen size at full hd, and building a health bar with border, fill, and a slider.

Connect the health bar to the player health by creating a health bar script that drives the slider’s max value and current value, updating with damage to reflect remaining health.

Implement an immortality mechanic in a 2D Unity platformer by giving the player a few seconds of invulnerability after taking damage, managed by immortal time and a countdown.

Create a bonus collectible in a Unity 2D platformer by adding a box collider 2D as a trigger, tagging it, and using ontriggerenter2d to reset immortality and destroy the pickup.

Learn to create effects with a prefab pack in Unity, including electric and fire particle systems, and attach an immortal effect to the player with activation, scaling, and render order control.

Learn to implement extra health pickups in Unity by adding a health bonus, using health tags and collider triggers, updating the health bar, and keep current health within max health.

Master Cinemachine to make a 2D Unity camera follow your player with dead zones and damping. Use look-ahead and smoothing to create smooth, responsive camera movement.

Add a coin as a scoring pickup with a circle collider trigger, adjust its size and glow layering, then duplicate coins under an empty game object and save the scene.

Create a Unity coin scoring system by adding a pickup script, tagging coins, and using OnTriggerEnter to increment the coins variable, then destroy the coin and test in play mode.

Master prefabs in Unity to reuse game objects and apply changes across levels. Learn to instantiate effects from prefabs on collisions and manage overrides for scalable 2D platformer development.

Implement a coin pickup effect by instantiating a chosen pickup effect at the player's position when coins are collected, wiring it in the pickup script and testing the result.

Create a coin score UI in Unity by adding a text element, anchoring it to the top-right, styling the font and color, and wiring it to a score script.

Add a patrol enemy by importing slime sprites, slicing them with grid by cell size to create a walking animation, then add a circle collider to enable patrol.

Learn to implement enemy movement in the 2D platformer course for beginners in Unity by patrolling two points with transform and Vector3.MoveTowards, using speed control and flipX.

Implement enemy sprite flipping by accessing the sprite renderer with GetComponent in start, then set sr.flipX true for point a and false for point b, compile and test.

Implement enemy damage in Unity by using trigger colliders and a damage script that checks the player tag, then add another enemy with separate patrol points and speeds.

Learn to implement 2D shooting in Unity: create bullets, a fire position, and a bullet prefab, using Rigidbody 2D and Circle Collider 2D with zero gravity and left mouse input.

Create a player bullet script, attach it to the bullet prefab, set the bullet speed, move it with transform.right via rigidbody 2D velocity, and destroy bullets after two seconds.

Enhance shooting in the 2d platformer by adding a time between shots with a coroutine and a can shoot flag, preventing spam and fixing left-side shooting.

Fix the shooting direction in a 2d platformer by using a boolean is facing right to fire bullets right or left, guided by the player script and an if-else.
