Complete Unity® guide: make an action shooter from scratch!

Learn to make a game camera follow the player in Unity with an offset. Apply smooth movement using lerp and switch to fixed update for physics.

Design a bullet prefab, script simple forward movement with delta time, and instantiate bullets on space press to enable shooting in a Unity action shooter.

Explore how to implement and customize particle effects for bullets using Unity, adjusting lifetime, speed, size, emission, shape, color gradients, and world versus local simulation to create dynamic trails.

Create and customize multiple bullets in Unity by duplicating prefabs, adjusting materials, colors, sizes, speeds, angles, and damage, and prepare for a charge shot mechanic.

Create a base enemy class with health, damage handling, and destruction logic, using on trigger enter to apply bullet damage and destroy the enemy when health reaches zero.

Create a walking enemy in Unity with a walking enemy script that moves a rigidbody left and right, toggles direction on a timer, and uses a box collider.

Create and apply custom physics materials in Unity to control friction for the player, enemies, and rocks, and tune knockback and invincibility timing for responsive 2D combat.

Improve collision handling by correcting knockback direction and ensuring knockback is not overridden by movement logic, controlled through an invincibility timer and zero-friction physics materials for smoother rock interactions.

Create an empty game object for the flame thrower with a flame particle system and collider, then script the flame invincible so bullets pass through while it harms the player.

Design a shooter enemy in Unity that detects the player within a sphere cast all search radius, using it to trigger shooting bullets and handle basic enemy setup.

Create an enemy bullet in Unity that hurts the player on trigger enter. Extend the bullet, set speed and damage, destroy after hit, and test the shooter.

Implement a shooter that spawns enemy bullets with a three-second cooldown, instantiating a bullet prefab at the shooter's position and directing fire toward the player.

Learn to implement burst fire in Unity using coroutines, spawning multiple bullets with configurable burst length, interval, and vertical noise to create varied shots.

Set the max distance to zero and center the fear cast on the shooter enemy as the player nears. Tweak the fear collider and search radius to constrain bullets.

Design interactive doors and button puzzles in Unity by creating a door with a trigger button and a movable container, using a lerp-based open animation.

Learn to create an interactive button in Unity that opens a door using a trigger collider, a simple script, and visual feedback with materials.

Create a reusable trigger element script in Unity that supports triggering doors, platforms, chests, or teleporters, wiring a button target to call overridden trigger methods and convert them into prefabs.

Learn to implement a timed button in Unity that activates a door for a set duration using a countdown timer, pressed duration, and reset logic.

Learn to design moving platforms in Unity by building a moving platform with movement offsets, speed, and wait times, using 3D objects, coroutines, and lerp for dynamic level design.

Create a simple Unity teleporter by building a two-cube exit, applying a blue material and a particle system, and using a trigger collider with a teleporter script that links exits.

Define a private just-teleported flag, expose it via a public property, and use a guard return in on trigger enter to prevent the infinite loop.

Learn to make teleporters respond to triggers by extending the trigger element, overriding trigger methods, and controlling particle systems and colliders, while wiring game buttons to doors, teleporters, and platforms.

Define a cutscene trigger region with a box collider to move the camera to a target position using lerp, then return and disable the trigger after activation.

Learn to lock and unlock player controls during cutscenes by routing control through the game camera, avoiding direct player references, and ensuring smooth resumption of gameplay.

Learn to create and rotate power ups in Unity, including invincibility and super charge, using trigger colliders, a power up type enum, and a simple collection flow.

Learn to implement health and time texts in Unity using a game controller script, with proper text sizing, localization awareness, and readability through a background bar.

Design a power-up bar in Unity by scaling a green image to reflect duration, anchoring it to the top bar, and updating it via a game controller event.

Animate the power bar with a coroutine on power-up collection, using elapsed time and duration to scale the bar and display the power-up name in UI.

Learn to use the magic of voxel to create pixel-like objects and master basic camera controls, including orbiting, panning, and zooming with mouse and keyboard.

Explore magica voxel tools in this crash course, resizing the work area and painting with line, circle, and square brushes. Learn erase, mirror axes, and color and geometry modes.
