⚙️ Configuration Options

Edit these at the top of the script:

TRIGGER_PHRASE = "reward"          # Text to detect for trigger
TRIGGER_HITS_REQUIRED = 2          # Consecutive detections needed
SPOTS_REQUIRED = 5                 # Number of letter spots
FRAMES = 50                        # OCR attempts per letter
TYPE_INTERVAL = 0.15               # Delay between keypresses (seconds)
PRESS_ENTER_AT_END = True          # Auto-press Enter after typing
CLICK_CENTER_BEFORE_TYPING = True  # Click game window center first

🐛 Troubleshooting

❌ "Could not find window containing: 'EndlessOnline'"

• Make sure the game window title contains "EndlessOnline"
• Update WINDOW_TITLE_SUBSTR if your window has a different name

❌ OCR returns wrong letters

• Increase FRAMES (default 50) for more samples
• Adjust TYPE_INTERVAL if letters are typing too fast
• Check DEBUG_PREVIEW = True to see OCR preprocessing

❌ Keys not registering in game

• Ensure the input field is active (cursor blinking)
• Try increasing TYPE_INTERVAL (e.g., 0.20 or 0.25)
• Make sure game is truly focused

❌ Tesseract not found

• Verify installation path: C:\Program Files\Tesseract-OCR\tesseract.exe
• Update line 25 if installed elsewhere

📝 Notes

• ⚠️ The script uses real keyboard input via SendInput
• 🎮 Game must be focused and input field active
• 🔄 Run the script fresh for each captcha session
• 💾 Selection areas are NOT saved between runs
