Master if blocks in Unity by testing conditions, comparing values, and driving actions like rotating a cube and printing console messages.

Convert a cube into a prefab in Unity and instantiate many at random positions using for or while loops. Control count with cube amount and random area for dynamic layouts.

Explore how to use Unity's input system to move a cube with key presses, look around with the mouse, and jump with space, including a chase camera.

Create a Unity project to learn input handling, attach a game controller script, print hello world, and implement left/right movement and jump using get key and get key down.

Create and customize a 3D player cube in Unity, assign a material, and script keyboard-controlled movement using transform.position, speed, and delta time for consistent play across devices.

Control a kart-style player in Unity using transform.forward, input keys, and delta time; rotate around the vertical axis and cycle cameras with the mouse.

Cycle through four cameras in Unity by placing them in an array, enabling only the active one via a camera index, and switch with mouse input.

Learn to use Unity prefabs to reuse objects like explosions, coins, and enemies, creating one prefab and replicating it across the scene to tune the game.

Learn to use prefabs in Unity to create reusable game objects, instantiate bullets from a player script, and control shooting with the mouse using Rigidbody physics.

Control bullet direction by exposing a shooting direction on the bullet prefab, instantiate bullets, use normalized vectors with random ranges for varied angles, then destroy bullets after a set lifetime.

Implement a simple explosion effect in Unity by spawning prefab particles with random directions using rigidbodies, applying forces, and destroying them after a short lifetime when bullets hit a wall.

Learn to implement collision detection in Unity by tagging surfaces with trigger explosion, handling on collision enter, and spawning explosion prefabs at bullet impact.

Explore how to build a simple two-player air hockey game in Unity 3D with a 2D perspective, covering art integration, physics, and game logic through step-by-step scripting.

Set up a new Unity 2D air hockey project, import 3D assets, organize folders, place and resize the paddle and puck, adjust the camera and lighting, and save the scene.

Activate physics in Unity by adding a box collider to the table, a rigid body to the paddle, and a convex mesh collider to the puck, then freeze vertical position.

Learn to implement paddle movement in Unity using horizontal and vertical input axes, a Rigidbody velocity, and a custom paddle script to support keyboard and gamepad controls.

Create invisible boundary walls with box colliders for left, right, and middle bounds, then use layers and collision settings to prevent puck-wall collisions while keeping the paddle constrained.

Create physic materials for puck and boundary, set friction to zero and bounce to one, apply them to colliders, and freeze the puck’s rotation with a sphere collider.

Apply deceleration to the puck in Unity by multiplying its rigidbody velocity by a deceleration factor in fixed update, test 0.95 to approach zero velocity for score logic.

Explore collision-based gameplay in Unity by creating bounds and a goal, tagging the goal, and using puck collisions to trigger scoring and reset via a game controller.

Declare the on-goal event via a puck delegate, then have the game controller subscribe to update scores and reset the puck position for each goal.

Add a second player in Unity by configuring separate horizontal and vertical axes for player one and two, updating the paddle script with a player number, and testing keyboard controls.

Set up a Unity 2D UI canvas, create a score text, and wire it to the game controller to display live scores and reset after a three-point win.

Learn to implement a restart in Unity: detect wins, show player wins, hide the puck, and restart the scene after a short countdown.

Attach an audio source to the puck, assign an audio clip, and call AudioSource.Play on collisions to play sounds, and reuse the same method for background music.

Tune the air hockey game score by exposing a public variable to set the score limit, and adjust paddle speed with the input manager sensitivity for keyboard controls.

Learn to build a 2D space shooter in Unity by creating a 2D project, adding player, enemy, and projectile sprites, and scripting movement and prefab spawning.

Build an enemy spawner that instantiates enemies from a prefab at random x above the player, with starting y around 20 and a spawn timer, 2D collision and score logic.
