# Interactive A* Pathfinding Algorithm Game

## Model Overview

An interactive educational game that visually demonstrates the A* pathfinding algorithm using PyQt5. This application provides a hands-on way to understand how one of the most popular pathfinding algorithms works through real-time visualization.

## What is A* Algorithm?

A* (A-Star) is a graph traversal and path search algorithm that finds the shortest path between nodes. It combines the strengths of Dijkstra's Algorithm (guaranteed shortest path) and Greedy Best-First Search (efficiency) by using both:

- **g(n)**: Actual cost from start node to current node
- **h(n)**: Heuristic estimated cost from current node to goal
- **f(n) = g(n) + h(n)**: Total estimated cost

## Features

### 🎮 Interactive Gameplay
- Set custom start and end positions
- Place and remove obstacles in real-time
- Visualize algorithm execution step-by-step
- Adjustable animation speed

### 🎨 Visual Elements
- **Green**: Start node
- **Red**: End node  
- **Gray**: Obstacles/walls
- **Yellow**: Open set (nodes being considered)
- **Light Red**: Closed set (evaluated nodes)
- **Blue**: Final optimal path

### ⚙️ Technical Features
- 20×20 grid system with 8-directional movement
- Real-time cost display (g, h, f values)
- Manhattan distance heuristic
- Pause/Resume functionality
- Reset and clear options

## Quick Start

### Installation
```bash
pip install PyQt5
```

### Run the Game
```bash
python astar_game.py
```

### Usage Instructions
1. Select "Start Point" mode and click a grid cell to set start position
2. Select "End Point" mode and set destination
3. Use "Obstacles" mode to add walls
4. Click "Start" to run the algorithm
5. Watch the visualization and learn!

## Educational Value

This game is perfect for:
- 🎓 Computer Science students learning algorithms
- 🎮 Game developers implementing pathfinding
- 🔍 Anyone curious about how navigation algorithms work
- 💡 Understanding heuristic search methods

## Algorithm Details

### Heuristic Function
Uses Manhattan distance: `h(n) = |x₁ - x₂| + |y₁ - y₂|`

### Cost Calculation
- **Movement Cost**: Euclidean distance between nodes
- **Total Cost**: f(n) = g(n) + h(n)
- **Node Expansion**: Always expands node with lowest f(n) first

### Key Properties
- **Complete**: Always finds a solution if one exists
- **Optimal**: Always finds the shortest path
- **Efficient**: Explores fewer nodes than Dijkstra's algorithm
