• System tray icon with quick access menu
• Stays on top of all windows

---

Requirements

• Operating System: Windows 10/11
• Python: 3.13
• Dependencies:
  • statsapi — MLB game data
  • PyQt5 — GUI framework
  • Cython (optional) — performance optimizations

---

Installation

1. Clone or Download

git clone https://github.com/yourusername/MLB-TCKR.git
cd MLB-TCKR

2. Install Dependencies

pip install -r requirements.txt

3. Setup Assets

The ticker automatically creates its data directory at %APPDATA%\MLB-TCKR\:

• MLB-TCKR.images\ — Place team logo PNG files here (e.g., yankees.png, dodgers.png)
• led_board-7.ttf — Custom LED font (optional)
• mlb.png — System tray icon (optional)
• MLB-TCKR.Settings.json — Auto-generated on first run

4. Run

python MLB-TCKR.py

---

Performance Build (Optional)

For maximum smoothness, compile the Cython optimizations:

.\build_performance.bat

This compiles the Cython module and automatically reads the version from MLB-TCKR.py to update all version resource files before building. The application falls back to pure Python if the Cython module is not present.

Cython functions:

• calculate_smooth_scroll() — Optimized scroll calculations
• get_pixel_position() — Fast float-to-int conversion
• adjust_speed_for_framerate() — FPS-aware speed scaling

Performance targets:

• With Cython: ~1–2% CPU, smooth 60 FPS
• Without Cython: ~3–5% CPU, smooth 60 FPS

---

How It Works

Data Flow

1. Background Worker Thread (GameDataWorker) fetches data from MLB-StatsAPI
2. Signal/Slot Communication passes game data to main UI thread
3. Ticker Builder creates a pixmap with all games (duplicated for seamless loop)
4. 60 FPS Animation scrolls content smoothly with sub-pixel precision
5. Intelligent Polling adjusts update frequency based on game status

Game States

• Live/In Progress: Scores, runners, outs, inning, pitcher info (updates every 10s)
• Final/Completed: Final scores with "F" indicator
• Scheduled/Pre-Game: Game time and probable pitchers

Polling Intelligence

• Active Games: Updates every 10 seconds (configurable)
• Warmup / Pre-Game: Immediately exits idle mode; polls at the normal update interval
• All Games Finished: Switches to idle polling
• Midnight Rollover: Detects new day, fetches the next day’s schedule
• Automatic Resume: Returns to normal polling when games begin

Baseball Diamond

• Three Bases: Triangle formation (1st, 2nd, 3rd)
  • Green (#00FF00) when runner is on base; gray outline when empty
• Three Outs: Circles below the bases
  • Red (#FF0000) for recorded outs; gray outline for remaining outs
• Inning Indicator: Gold text (#FFD700)
  • T5 = Top of 5th, B5 = Bottom of 5th, F = Final

Score Change Glow

When a score updates, the changed number immediately switches to gold (#FFD700). After 2.5 seconds it returns to white. Away and home scores are tracked independently. The glow uses a high-precision elapsed timer and invalidates the render cache automatically to ensure smooth transitions.

Moneyline Odds

Odds are fetched from The Odds API on a configurable interval (default: 15 minutes). A free API account provides enough quota for a full season of use. Odds appear inline in the ticker as color-coded moneyline values (e.g., +820 / -2200). Odds are shown for scheduled and live games and hidden once a game is final. Configure your API key and refresh rate in Settings → Odds tab.

---

Moneyline Odds Setup

1. Sign up for a free account at the-odds-api.com
2. Copy your API key from the dashboard
3. Open Settings (press .) → Odds tab
4. Paste your key into the Odds API Key field
5. Enable Show Moneyline and set your preferred Refresh Interval
6. Click OK — odds will appear on the next fetch

Team Logos

Logo files go in %APPDATA%\MLB-TCKR\MLB-TCKR.images\. Use lowercase team nicknames with no spaces:

• yankees.png, redsox.png, dodgers.png, whitesox.png, bluejays.png, etc.

Case-insensitive lookup is used. If a logo is missing, the ticker falls back to a colored square with the team abbreviation.

---

Troubleshooting

Ticker doesn't appear

• Check if another window is in fullscreen mode
• Restart the application
• Verify Windows AppBar registration in console output

Logos don't show

• Ensure PNG files are in %APPDATA%\MLB-TCKR\MLB-TCKR.images\
• Check file naming (lowercase team nickname, no spaces)
• Colored fallback squares will be used if logos are missing

Scrolling is choppy

• Run build_performance.bat to enable Cython optimizations
• Close resource-heavy applications
• Reduce ticker height in settings

Games not updating

• Check internet connection
• Verify MLB-StatsAPI is accessible
• Try manual refresh from the tray menu or press G

Settings don't save

• Ensure %APPDATA%\MLB-TCKR\ is writable
• Check for JSON syntax errors in the settings file
