Learn to Make a 3D Platformer Game with Unity & C#

Explore basic player movement and jumping in Unity using a character controller, reading horizontal and vertical inputs from the input manager, and applying a speed-based move with Time.deltaTime.

Implement jumping in a Unity player controller by applying gravity to the vertical velocity, reading jump input, and computing an initial velocity from jump height using a square root formula.

Fix jumping in a Unity 3D platformer by controlling vertical velocity with ground checks, using raycast to set isGrounded with a ground layer mask, and tuning ground radius and layers.

Rotate the player to face the move vector and update the forward direction when moving, so the character looks in the correct direction before jumping.

Open the barbarian character in the Unity project, assign idle, jumping, and running animation clips, configure the animator controller, set default states, and enable looping for the running animation.

Create and manage animation transitions in Unity for a 3D platformer by using speed and is grounded parameters to switch between idle, run, and jump with instant transitions.

Set up follower camera in Unity with Cinemachine by configuring a virtual camera, follow targets, and framing transposer, then tune damping, dead zones, and look ahead time for smooth tracking.

Create a c# script to control the player's health with current and max health; initialize health to max and implement a deal damage function that hides the player at zero.

Use a trigger collider bomb to damage the player. Create a damage script that calls player health deal damage via an instance, and verify health drops from 5 to 0.

Create a health UI in Unity by configuring a full HD canvas, then build a health bar with a border, fill, and a non-interactive slider to reflect health.

Connect the health bar visuals to the player health system using a health bar script with setMaxHealth and setHealth, integrating a Unity slider and player health to reflect real-time changes.

Implement a red damage overlay using a stretched UI image and a simple C# script; reveal damage on hit and fade back smoothly with move toward and a fade speed.

Learn to implement a universal scoring system by creating gem pickups, tagging them, using on trigger enter with a collider, updating score, logging with debug, and destroying gems after collection.

Display the score on the canvas via a UI text element, style it, anchor to the top right, and link it to the scoring calculation to reflect collected items.

Design the game environment by texturing the ground plane with tile and dirt textures, adjusting tiling and materials, and using unpacked prefabs for trees and decorations.

Learn how to customize your Unity game's look by adding and swapping skyboxes, adjusting lighting with directional, spotlight, and point lights, and fine-tuning color and intensity for a cohesive environment.

learn to add an enemy in Unity by placing a rogue model, adding a box collider, and setting up idle and running animations with in range boolean to trigger chasing.

Calculate the distance between the enemy and the player to trigger chasing within a detect range, using a Unity C# enemy controller and animator to loop the running animation.

Create an enemy that chases the player with a move towards function, calculates position and direction, ignores y to stay grounded, and uses look at to face the player.

Create enemies that damage the player by reusing the damage player script with OnTriggerEnter. Test in play mode, adjust enemy health, and add more enemies using the character pack.

Add a horizontal melee attack animation to the barbarian and trigger it with an attack parameter in Unity's animator, using idle-to-attack transitions activated by left click.

Learn to detect enemies in a Unity C# 3D platformer by implementing attack detection with physics overlap sphere, an attack point, and enemy layers, plus visual gizmos and debug validation.

Create an enemy health system with current health, max health, and damage amount, destroy the enemy when health reaches zero, and call take damage from the player via GetComponent.

Create an impact effect with Unity’s particle system to enhance enemy destruction. Tune duration, lifetime, speed, color, shape, and emission; then instantiate a prefab at the enemy’s position on death.

design and implement a unity main menu with start and quit buttons, ui text, and scene transitions using the main menu script and scene management by name.

Build a pause menu in Unity using a panel, pause screen text, and main menu and resume buttons; implement pause logic with public functions, keyboard toggle, and time scale control.

Fix a bug by preventing player input during pause in a Unity and C# 3d platformer, using a pause menu singleton to guard jumping and other actions until resume.

Equip a Unity audio manager to play sound effects with a Play SFX function. Assign audio sources, manage indices, and trigger damage, death, and jump sounds from gameplay scripts.

Drag the background music into the hierarchy, attach it to the music object so it plays on awake, and use an audio mixer to group SFX and music.

Learn to create multiple levels in Unity by adding new scenes and reusing core mechanics with prefabs. Implement environments, enemies, UI, and simple bomb mechanics to enable level transitions.

Explore level transitions in a Unity 3D platformer by creating a level-end trigger with a collider and OnTriggerEnter to load the next scene using SceneManager and the current scene index.
