📗Integration Features📗
Mail Delivery also includes a new command that can be used generate mail. This means you can use things like RCON (Minecraft Remote Console) or Content Creator Integration mod to manage in game mail from external applications!
(While this mod does not directly have Twitch integration it is easily possible using the command)
💻Commands💻
/sendmail
- Allows you to generate mail
Usage:
/sendmail [recipient] [author] [backgroundImageLink] [packageItem] [surpriseItem] [message]
OR
/sendmail [recipient] [author] [packageItem] [surpriseItem] [message]
/clearmediacache
- (Client Only) Clears your image cache for custom backgrounds. You can use this or the "Clear Cache" button in the Post Bin
🚧Known Incompatibilities/Issues🚧
• JEI (Just Enough Items):
Minor inconvenience; The JEI container overlay likes to render itself on top of the postal bin's GUI because of the type that the menu was built on. If it's in your way you can press Control + O to toggle JEIs overlay visibility on or off (Control + O being the default keybind of course). You will recieve an in game hint about this upon joining if enabled in the config.
🔨Version Support Info🔨
Until I make the decision the mod will be explicitly for the Forge modloader. Please refrain from making Version Support tickets on the issues tracker about porting to other modloaders.
