🚀 Quick Start

Installation

pip install pfagd

Create a New Game

# Create a new project
pfagd scaffold mygame

# Navigate to project
cd mygame

# Run on desktop
pfagd run main.py

# Build for Android
pfagd build-android main.py

Simple Game Example

from pfagd.engine import Game, Scene
from pfagd.ui import Button, Label
from pfagd.assets import AssetManager

class MainMenu(Scene):
    def on_enter(self):
        title = Label("My Game", pos=(300, 400))
        self.add_widget(title)
        
        start_btn = Button("Start", on_press=self.start_game)
        self.add_widget(start_btn)
    
    def start_game(self):
        self.manager.switch_to("GameScene")

class GameScene(Scene):
    def on_enter(self):
        self.player = self.add_sprite("player.png", pos=(100, 100))
        
    def update(self, dt):
        # Game logic here
        pass

# Create and run game
game = Game(
    title="My Game",
    start_scene=MainMenu(),
    assets=AssetManager("assets/")
)
game.add_scene(GameScene())
game.run()

🛠 CLI Commands

# Project Management
pfagd scaffold <name>              # Create new project
pfagd run <file> [--debug]         # Run game on desktop
pfagd run <file> --hot-reload      # Run with hot reload

# Building
pfagd build-android <file>         # Build Android APK
pfagd build-desktop <file>         # Build desktop executable

# Assets
pfagd import-assets <dir>          # Import and optimize assets

# Monetization
pfagd add-monetization admob       # Add AdMob ads
pfagd add-monetization iap         # Add in-app purchases
pfagd add-monetization analytics   # Add analytics tracking

📚 Examples

Basic Platformer

class Player(Scene):
    def on_enter(self):
        self.player = self.add_sprite("player.png")
        
    def update(self, dt):
        # Gravity
        self.player.velocity[1] += 500 * dt
        
        # Ground collision
        if self.player.pos[1] > 400:
            self.player.pos[1] = 400
            self.player.velocity[1] = 0

Adding Monetization

# Add AdMob ads
from monetization.ads import AdMobManager

ads = AdMobManager("your-app-id", "banner-id", "interstitial-id")
ads.show_banner("bottom")

# Track analytics
from monetization.analytics import AnalyticsManager

analytics = AnalyticsManager("your-api-key")
analytics.track_level_start("level_1")

🎯 Target Use Cases

PFAGD is perfect for:

• Indie game developers wanting to reach both desktop and mobile
• Prototype development with rapid iteration
• Educational games that need cross-platform deployment
• Casual mobile games with monetization requirements
• Game jams where speed of development is crucial
