Voice chat
SPED includes voice chat for communication between players.
RP and Global Chat
The text chat is divided into two channels.
RP Chat is used for roleplay and communication within the surrounding area.
Global Chat is used for communication across the entire server.
This makes it possible to keep roleplay conversations separate from general server communication.
Automatic item cleanup
Dropped items are automatically removed from the world every 3 minutes.
This helps prevent unnecessary item accumulation during gameplay.
Music Block
Play your own music using the Music Block.
The block supports .ogg and .wav audio files, allowing you to add your own music to the game.
Work in progress
SPED is being developed quickly, so some features may still be unfinished.
Some mechanics may not work as intended, contain bugs or change significantly in future updates.
The current version should be considered a work in progress.
