Download the Unity personal edition and install it, then review the license. Enable core components and platform modules (Android, iOS, WebGL) to begin building your 3D portals clone.

Learn to create a simple hello world script in Unity using C#, extend MonoBehaviour, attach it as a component, and view the debug message in the console.

Learn to organize Unity C# scripts by defining private void methods, using parameters and return values, and calling them from start to print messages and sum numbers.

Explore for loop and while loop usage in Unity by counting iterations, printing debug log messages, and avoiding infinite loops, with examples using incrementing numbers and random range logic.

Import Unity standard assets and enable the first person controller to walk, jump, and look around. Build a simple floor and walls and keep a single camera.

Activate physics by adding a rigid body to the cube and experiment with mass, gravity, and collisions. Save the scene and prepare for dragging cubes in the portal game.

perform a raycast from the player's position in the forward direction to detect hits when clicking, printing the hit object's name and using a 1.5 unit grabbing distance.

Create a Unity C# script to enable grabbing by defining a box class that extends MonoBehaviour, adding a grabble object component, and using GetComponent<GrabObject>() with testing via drag-and-drop and play.

Implement hold and release mechanics in Unity. Use the camera forward direction for grabbing objects and apply the throw force through the rigid body, while managing colliders and prefabs.

Design a simple 3D button in Unity by creating an empty button object, a cylinder base, a separate model for animation, adjusting colliders, and applying a red material for visibility.

Learn to implement responsive button animation in Unity for a 3D portals clone, moving the button on press with Vector3 target positions, lerp and Time.deltaTime, including color change.

Learn to change a Unity button's color by toggling its material on press and unpress, using get component in children to access the renderer and switch between green and red.

Design a simple door for a 3D portals clone in Unity and Blender. Duplicate and resize walls, apply door and column materials, and add lighting.

Create a Unity door that responds to a trigger button, moves toward an open position with lerp, and uses local positioning for consistent movement.

Discover how to connect a pressure button to a door in Unity by wiring a trigger object, updating the button color on press, and triggering the door to open.

Build a 3D portals clone by creating prefabs for a door, pressure button, and orb; implement a trigger-based collectible that teleports the player to the next level in Unity.

Use a physics recast to identify the hit point on a surface the player looks at, then spawn portals at that point while preventing portal creation during object interaction.

Learn to spawn portals in Unity by creating a portal prefab, assigning materials, and instantiating at hit points, while managing two portals with a list and swapping between them.

Enter portals and teleport to the paired exit portal, using trigger colliders and on trigger enter, with an offset forward to prevent reentry and exit facing the correct direction.

Learn to render portals in Unity by creating two render textures, wiring a camera inside each portal, and swapping textures at runtime to display real-time views between portals.

Design a responsive Unity game interface with a canvas, instruction and time text, and a portal crosshair, plus anchors for multiple aspect ratios and a start-to-end flow.

Create a main menu for a 3d portals clone in Unity, featuring a UI canvas, title and instructions, and a play button that loads game scene via a scene controller.

Rename level 1, update lighting, and save; duplicate the scene for level 2. Convert the player to a prefab for consistent behavior while refining level design with a button and door.

Learn Blender basics, from navigation and camera controls to object manipulation, edit mode, and essential tools like extrude, loop cut, and the mirror modifier.

Model a portal gun in Blender by forming the handle, applying a mirror modifier, extruding to create the barrel and monitor, adding stabilizers with bevels and edge loops.

Unwrap and texture a gun model in Blender by setting seams, marking them, and adjusting UVs for clean, proportional texturing.

Color and texture a portal gun base with metallic gray, turquoise energy lights, black accents, and a red button, then export UVs and prep textures in Photoshop.

Texture a portal gun in Photoshop by building diffuse layers, applying brushed steel and rusted metal textures, duplicating and transforming pieces, and adjusting colors with overlay and multiply.
