NewManager - Game Manager

What is it?

NewManager is the main brain of the game. It:

• 🎮 Starts the entire game
• 🔄 Coordinates all components
• 📊 Tracks game state
• 🎯 Responds to player actions

Analogy: Like an orchestra conductor - doesn't play itself, but makes everyone play together.

Where to find it?

What do fields mean?

Field	What is it?	Why?
Matrix	Reference to board	Manager needs to know where the board is
Shape Spawner	Block generator	Creates new blocks on screen
Score Manager	Scoring system	Counts points, combos, highscore
Brain	Artificial intelligence	Selects block difficulty
Draggable Prefab	Block prefab	Template for creating new blocks
Shape Data Assets	Shape list	All possible blocks in the game

How does it work?

Game Start

1. NewManager.Awake()
   ↓
2. Initialize all components
   ↓
3. NewManager.Start()
   ↓
4. Generate first 3 blocks
   ↓
5. Wait for player input

Game Loop

Player places block
   ↓
NewManager.OnShapePlaced()
   ↓
Check if lines are full
   ↓
Clear full lines (if any)
   ↓
Update score
   ↓
Check if all 3 blocks used
   ↓ Yes
Generate new 3 blocks
   ↓
Check if any block can be placed
   ↓ No
GAME OVER

Key Methods (for programmers)

If you want to modify code, these are the most important:

OnShapePlaced(shape)

Called when player places a block on board.

// What it does:
1. Tells Matrix to add the shape
2. Checks for full lines
3. Clears lines if found
4. Updates score
5. Checks for game over

GenerateNewShapes()

Creates 3 new random blocks.

// How it works:
1. Asks Brain for 3 shapes (based on difficulty)
2. Tells ShapeSpawner to create them
3. Displays them on screen

CheckGameOver()

Checks if game should end.

// Checks if:
- Any of 3 blocks can fit anywhere on board
- If none fit → Game Over
- If at least one fits → Game continues

Events You Can Listen To

NewManager sends events that other scripts can listen to:

Event	When	Use for
OnGameStart	Game starts	Reset UI, animations
OnShapePlaced	Block placed	Sound effects
OnLinesCleared	Lines cleared	Visual effects
OnScoreUpdated	Score changes	Update UI
OnGameOver	Game ends	Show popup

Common Modifications

Change number of blocks per turn

Default is 3. To change:

// In NewManager.cs find:
private const int SHAPES_PER_TURN = 3;

// Change to whatever you want:
private const int SHAPES_PER_TURN = 5;

Change when game is over

Default: game over when NO blocks fit.

Want game over when only 1 block fits?

// In CheckGameOver() change:
if (CountPlayable(currentShapes) >= 1)  // was: >= 1
    return false;  // game continues

// To:
if (CountPlayable(currentShapes) >= 2)  // now requires 2
    return false;

Singleton Pattern

NewManager uses Singleton pattern - only ONE instance exists:

public static NewManager Instance { get; private set; }

This means you can access it from anywhere:

// From any script:
NewManager.Instance.GenerateNewShapes();
NewManager.Instance.CheckGameOver();

Important

Never create multiple NewManager instances! Always use Instance.

For Beginners

You don't need to understand all the code! Most settings can be changed in Inspector without touching scripts.
