Unity Game Dev for Beginners | Build a 3D Ball Runner Game

Learn to color 3d gameobjects in Unity by creating a material, choosing blue from the color palette, and dragging the material onto a cube or sphere.

Learn to organize a Unity scene by creating empty game objects and nesting cubes as children under a parent. Moving the parent moves all its children.

Create and attach a C# script in Unity by adding a movable script, exploring MonoBehaviour with Start and Update, and learning how inheritance reuses base code on game objects.

Move a sphere in three dimensional space using the rigidbody component, read horizontal and vertical keyboard input from axes, apply a Vector3 move, and jump with space.

Attach a move script to the ball, read arrow key input, and apply rigidbody movement in 3D space using Vector3, with a public speed adjustable in the inspector.

Learn to make a ball jump only once in Unity by using a collision check with a cube and a boolean isTouching, ensuring spacebar input works only when touching.

Attach the camera as a child of the sphere to make it follow the ball while avoiding rotation.

Learn how the main camera follows the sphere in a whiteboard animation, by computing the camera-sphere distance and updating the camera position each frame in Unity.

Learn to set a background texture for a game object in Unity by creating a background folder, importing an image, dragging it into the project, and previewing in play mode.

Restart the main scene when the ball collides with a ground cube using a ground restart script that loads the scene via the scene manager.

Create coin prefabs by turning a cylinder into a cone, apply a gold metallic material, switch to global coordinates, attach a points script, and group them under a coin collector.

Add a UI text element under a canvas to display points. Anchor it to the top-left, rename it coin text, and set the font size to 20 with bold styling.

Learn to increment the score by collecting coins in a Unity 3D ball runner setup, updating a UI text with the coin count starting at zero.

Implement a coin counter that starts at twelve, decreases as coins are collected, and transitions from the main scene to the end scene when the value reaches zero.

Learn to customize Unity user interface fonts by downloading 100 percent free fonts, importing them into assets/fonts, and applying size, color, and glow to the end scene.

Learn to move from the menu scene to the main scene on a button click by using a Unity C# script with scene management to load the main scene.

Import a free audio asset from the Unity Asset Store, attach an audio source, and play a one-shot audio clip when coins are collected.

Add restart and exit controls in Unity with a single script on a shared button. Restart switches from current scene to the main scene, while exit logs a debug message.

Learn to build and run a Unity game, configuring the player, icons, and resolution, selecting platform targets, and building a 3d ball runner game with C#.
