Complete 3D FPS Zombie Game in Unity for Beginners

Add a Unity character controller to the player, capture horizontal and vertical inputs from the input manager, and move the player using a public move speed and time delta.

Improve player movement by computing an actual movement vector that combines input with the character's orientation, using forward and right directions, normalization, and move speed to drive the controller.

Teach players to boost movement with a turbo speed when holding left shift, toggling between regular speed and run speed via current move speed.

Implement a basic jumping mechanic using a jump force, gravity modifier, and vertical velocity, triggered by the spacebar, with ground checks via the character controller to prevent mid-air resets.

Implement a ground check to prevent infinite jumping by using a ground sensor, layer masks, and raycast checks to allow jumps only when on the ground.

Set up a separate player viewpoint to have the camera follow the player using mouse input, with horizontal player rotation and vertical camera rotation, including invert look and vertical clamp.

Lock the cursor at game start and unlock with escape; re-lock on left click, using a Unity script to control a third-person controller and camera, and adapt to first-person games.

Make the main camera a child of the player and align its rotation to zero along the forward axis to create a first person view. Copy the transform and test.

Swap the player model by integrating a little ghost from the Unity Asset Store, attach the prefab to the player, and adjust the character controller for gameplay.

Learn to implement shooting mechanics in Unity by adding hands or a gun, using a center raycast to simulate hits, and exploring raycast-only shooting with optional bullets and debug feedback.

Configure a zombie with idle and run in place animations, transitions controlled by an in range boolean, and a script that detects the player within range using tags.

Shows how to make a zombie chase the player by computing direction, using Vector3.MoveTowards with delta time, rotate to face the player, and stay on the ground by ignoring y.

Develop a zombie combat system in Unity by linking the attack animation to run and idle transitions with a trigger and range conditions, and use a coroutine to time attacks.

Detect zombie–player interaction with an attack point and a visible sphere collider. Use Physics.OverlapSphere and a player layer mask to trigger damage and log when the player is damaged.

Learn to implement enemy health in Unity by creating a take damage function, tracking current and max health, and destroying the enemy when health reaches zero.

Implement zombie death animation using a falling back clip, a dead trigger, and any-state transitions; pause chasing by disabling the capsule collider and the enemy controller after death.

Add dramatic death effects using particle packs and prefab instantiation in Unity; swap impact effects, spawn a death effect at zombie position with identity rotation, and apply vibrations for realism.

Create a player health system in Unity using a PlayerHealth script with current and max health and a dealDamage method; use OnTriggerEnter with obstacles to reduce health and trigger death.

Create a health bar UI in Unity with a canvas, border and fill images, sprite 2D UI, anchor to the top-left, and configure a slider with fill and max value.

Connect the health bar UI to a player by syncing the slider's max value and current health, using set max health and set health methods to update on damage.

Set the enemy to damage the player using an attack point near the zombie's right hand. The script uses GetComponent to call the player's health to deal damage on collision.

Implement a red damage overlay in Unity that fades back using a UI image and moveTowards-based alpha fade, while tuning zombie attack timing and player health.

Make a smarter zombie in Unity by implementing NavMesh navigation and baking the scene. Use a NavMesh agent to set destinations like the player and test across versions.

Fix and fine-tune zombie ai in Unity by preventing dead bodies from reaching the player. Adjust navmesh agent stopping distance, radius, and idle state behavior for reliable damage.

Explore how to build and optimize Unity environments by importing prefab-based assets, applying materials and textures, baking navigation, and arranging a level with player, zombie, magazines, canvas, and camera.

Create a night scene by applying the Real Star Skybox light to the skybox material, test lighting, and add mesh colliders to buildings for a zombie game.

Explore Unity lighting by adjusting directional, point, and spotlight sources, learning to set intensity, range, and color, and attaching lights to zombies to create mood and atmosphere.

Create a main menu in Unity by configuring a full hd canvas with a background image and logo, then assemble a panel with new game, credits, and quit buttons.

Create and connect UI buttons to load scenes by name using SceneManager. Add all scenes in build settings, and test the start, quit, and credits buttons.

Create a credits scene in Unity with a black ui raw image background, scrolling credits text, a 15-second non-looping animation, and a script to return to the main menu.

Create a pause screen in level one by adding a UI panel, a bold 'paused' text, and two buttons for menu and resume, then test in play mode.

Implement a functional pause system in a Unity 3D FPS game by wiring menu buttons, pausing time with time.timeScale, and gating player input and cursor lock when paused.

Build a simple Unity quest to defeat two zombies, track defeated enemies, and check completion using a level one quest instance and get component references.

Learn how to add a second quest by placing a briefcase on a table, using a trigger and booleans to require briefcase found and enemies defeated.

Create a quest UI in Unity featuring a quest screen panel, quest texts (defeat two zombies; find secret briefcase), and a tab toggle that turns red to green when completed.

Create level-ending portals that unlock the next level only after quest completion, using triggers, colliders, and a universal level-end script with scene management.

Create UI messages in Unity, display a 'you shall not pass' panel until quests are complete, and a 'case found' screen after finding the briefcase, using triggers and coroutines.

Craft cutscenes in Unity by using a separate cut scene camera, animator, and timed UI prompts to guide players through quests and reveal portals.
