The Complete Beginners Guide: Make Unity Games from Scratch

Design a simple bullet and create a prefab. Implement shooting with forward movement, a lifetime, and destruction, while managing direction and instantiating bullets to organize the scene.

Use particle systems to create bullet trails by adjusting lifetime, speed, and size. Shape, color, and render particles, and switch between world and local space for dynamic effects.

Implement a charge shot mechanic in Unity by holding space to charge, displaying charge effects for the bullet prefabs via a calculated index and strength, and shooting on release.

Create a base enemy class that handles health, takes damage from bullet collisions via onTriggerEnter, and destroys itself when health reaches zero, providing shared behavior for multiple enemy types.

Create a rock obstacle in Unity with a container and rigidbody, apply material, and script it as a reusable enemy prefab; shrink the container on hit to show damage.

Destroy particle systems when they finish to free memory, by writing a Unity script that gets the particle system component and destroys the game object once isAlive returns false.

Learn to create a walking enemy in Unity that moves left and right using a walking enemy script and a movement timer, powered by a rigidbody.

Learn to implement a health system and knockback for the player in Unity, making enemies deal damage via collisions with invincibility frames to prevent rapid hits.

Create custom physics materials, assign them to the player and enemies, and tune dynamic and static friction with minimum friction combine. Test in play mode and adjust knockback.

Correct knockback to push enemies left, ensure movement runs only when not in knockback, and adjust knockback and jump forces; introduce a zero-friction physical material to fix rock collisions.

Learn to implement burst fire in Unity using coroutines to shoot multiple bullets with controlled intervals and vertical noise, by defining burst length, burst interval, and burst noise.

Develop and place a turret enemy in Unity that endlessly looks at and shoots the player using a sphere cast for detection, a bullet prefab, and a timed cooldown.

Design a door and a button in Unity, using a container and a script that moves the door with a target position and lerp for smooth opening.

Learn to build a Unity button that opens a door using a trigger collider, a C# script, and visual feedback with pressed and unpressed materials.

Learn to implement trigger elements in Unity by creating a reusable trigger script, extending it in derived classes, and wiring doors and platforms to respond to button presses.

Implement a timed button in Unity that activates for a set duration, triggers a door and other targets, and resets to its unpressed state after a countdown.

Create moving platforms in Unity with offset targets, coroutines, and lerp to control speed and wait times for dynamic, triggerable levels.

Implement a teleporter loop fix by using a private boolean flag, expose it via a public property, and guard on trigger enter to prevent re-teleport, enabling smooth cross-side teleportation.

Learn how to extend the trigger element to power the teleporter and platform in Unity, implement trigger and on trigger methods, manage particle systems and colliders, and support start-on-trigger behavior.

Define trigger patterns for doors, teleporters, and moving platforms, defaulting to disabled and clearly ordering start and trigger states. Test changes, connect controls, and tune timers for reliable activation.

In Unity, create power ups like invincibility and a supercharged shot, using a rotating prefab with particle effects, and an enum to differentiate power-up types upon collection.

Learn to implement a health display in Unity, wiring a game controller to update a health text from the player's health, with a time counter and localization considerations.

Learn to implement cutscenes in Unity by coordinating the game camera and UI bars, using delegates and events to start and end cutscenes and display messages.

Implement a pause feature using a pause button and pause area, bind it to a game controller, and control time with time scale for pausing and resuming.

Learn to create and save new scenes, set up a canvas UI with play and menu buttons, and switch between scenes using scene manager while adding them to build settings.
