Flizzy Burd 🐦 is an exciting 2D platformer 🎮 where players take control of a brave little bird navigating through an endless world 🌍 filled with challenges. The bird must flap its wings 🪽 at the right time ⏱️ to avoid obstacles 🏔️ and stay alive 💥.
🐦Bird Script🐦
1. VARIABLES:
- myRigidbody: A reference to the bird’s Rigidbody2D component (handles the bird's physics 🧲, gravity 🌍, and movement 🏃♂️).
- flapStrength: The strength 💪 of the bird's flap 🦅 (how high the bird flies when the spacebar is pressed ⬆️).
- logic: A reference to the LogicScript 📜, which controls the game’s logic (like checking if the game is over 🚨).
- birdIsAlive: A boolean 🔘 that tracks whether the bird is still alive 🐦❤️ or has crashed 🪦.
2. START METHOD:
- Sets logic to the LogicScript (finds the object in the scene using the "Logic" tag 🏷️) so the bird can interact with the game’s logic (like game-over checks and scoring 🎯).
3. UPDATE METHOD:
- Called every frame ⏱️ to check if the player presses the spacebar (flap button 🦅). If the bird is still alive (birdIsAlive is true 🐦✅), it applies an upward force ⬆️ to the Rigidbody2D (making the bird "flap" 🐦💨).
- The flapStrength determines how high the bird will fly with each flap 🌟.
4. ONCOLLISIONENTER2D METHOD:
- Triggered when the bird collides 🛑 with another object (e.g., a pipe 🏗️ or obstacle 🪵).
- When a collision happens, it calls the gameOver() method from the LogicScript 🕹️ to end the game 🛑 and sets birdIsAlive to false ❌, stopping the bird's movement 🐦💀.
IN SUMMARY:
The BirdScript makes the bird flap 🦅 when the player presses the spacebar ⬆️. If the bird crashes 🛑 into anything (like an obstacle 🏗️), it triggers a game-over sequence 🚨, stopping the game 🛑. It's a basic script for handling player input (flapping 🐦) and detecting collisions (game over 💀).
Logic Script
WHAT IT DOES:
- This script manages the game logic for scoring 🎯, restarting 🔄, and handling the game over 💀 state in Flizzy Burd.
FEATURES:
- addScore(int scoreToAdd): Increases the player's score 💯 by the given amount ➕ and updates the score displayed on the screen 🖥️.
- restartGame(): Reloads the current scene 🔄 to restart the game, giving the player a fresh start 🌱.
- gameOver(): Displays the game over screen 💔 when the game is over 🛑, signaling the end of the bird's journey 🚶♂️💨.
- The script keeps track of the player’s score 🎯, displays it in the UI 🖥️, and provides functions to restart the game 🔄 or show a game over screen 💀 when the bird’s flight ends.
Pipe Middle Script
WHAT IT DOES:
- This script manages the scoring logic 🏆 when the bird 🐦 passes through the middle of a pipe 🚧 in Flizzy Burd. Here's what each part does:
- Start(): It finds the LogicScript attached to the game object tagged with "Logic" 🔍 and stores it in the logic variable 📥.
- OnTriggerEnter2D(Collider2D collision): This method checks when the bird 🐦 passes through the middle of the pipe 🚧 (the "trigger" area).
- If the bird (on layer 3) 🐦 collides with the pipe 🚧, it calls the addScore(1) function from the LogicScript 🎯, increasing the score by 1 ➕.
- This script ensures that the player earns points 🎯 whenever the bird 🐦 successfully passes through a pipe 🚧, adding to the challenge and excitement of Flizzy Burd!
Pipe Move Script
WHAT IT DOES:
This script handles the movement 🏃♂️ and deletion 💥 of pipes 🚧 in Flizzy Burd. Here's what each part does:
- moveSpeed: Controls how fast the pipe 🚧 moves across the screen ⏩.
- deadZone: The X position 🗺️ at which the pipe 🚧 is destroyed 💥.
KEY ACTIONS:
Update():
- Moves the pipe 🚧 to the left across the screen ⬅️ at a speed determined by moveSpeed.
- If the pipe 🚧 moves past the deadZone (a specific X position), it gets destroyed 💥 using Destroy(gameObject).
This script ensures the pipes 🚧 move across the screen and are deleted when they exit the visible area 🌍, preventing them from cluttering the game world 🌪️.
Pipe Spawn Script
WHAT IT DOES:
This script spawns pipes 🚧 in Flizzy Burd at regular intervals. Here's what each part does:
- pipe: The pipe 🚧 prefab that gets instantiated (spawned) in the game world.
- spawnRate: The time 🕒 between each pipe spawn. Default is 2 seconds.
- timer: Keeps track of the time passed and triggers a new spawn when it reaches spawnRate.
- heightOffset: Determines how far the pipes 🎮 can spawn from the origin point (higher or lower).
KEY ACTIONS:
Start():
- Calls the spawnPipe() function to spawn the first pipe 🚧 when the game starts 🎮.
Update():
- Checks if the timer is less than the spawnRate. If true, it adds time 🕒 to the timer.
- If the timer exceeds the spawnRate, it calls spawnPipe() to spawn a new pipe 🚧 and resets the timer.
spawnPipe():
- Spawns a pipe 🚧 at a random Y position within a defined range (between lowestPoint and highestPoint).
- The pipe 🎮 will always spawn at the same X position but at different Y heights to create variety.
- This script ensures endless pipes 🚧 are spawned at regular intervals to keep the game fun and challenging 🏃♂️🎯.
