Highlights

• Offline teleports: set where a player will appear next time they join
• Online teleports: move players instantly, including across dimensions
• Bulk @a: teleport all non-admins online now and auto-schedule all offline non-admins
• Exemption whitelist: skip specific UUIDs from bulk teleports
• Pending management: list and cancel pending teleports
• Uses simple JSON storage; survives restarts

Requires: Forge 47.x for Minecraft 1.20.1, Java 17

Bulk @a behavior

When you run /offtp @a <x> <y> <z> <dimension>:

• Online non-admins are teleported immediately
• Offline non-admins are automatically scheduled for next login
• Admins (permission level >= 2) are skipped
• Players on the exemption whitelist are always skipped
• You get a summary of applied/scheduled/skipped

How it works

• Online: If a target is connected, they are teleported instantly (and cross-dimension if specified)
• Offline: If a target is offline, their next-login position and dimension are saved to config/ferventes_offline_teleports.json
• On join: Offline teleports are applied the moment the player joins
• Bulk @a: The mod scans playerdata to include known offline players in scheduling

Storage: JSON under config/

• ferventes_offline_teleports.json: pending teleports
• ferventes_offline_teleport_exempt.json: whitelist (array of UUID strings)

---

Permissions

• Command usage requires operator level 3 by default (same as vanilla /tp)
• Bulk skipping logic treats admins as permission level >= 2 for safety

Q&A

Q: Is this server-side only?

• A: Yes. Install on the server. Clients don't need it to connect.

Q: Can I use this with other teleport mods?

• A: Yes. This mod only schedules/sets player positions; it doesn't change world gen or entities.

Q: Will it work with Fabric via Connector?

• A: Only Forge is supported. It may work via connectors, but issues should be reproduced on pure Forge before reporting.

Q: Does it support modded dimensions?

• A: Yes. Use the full dimension ID like modid:dimension_name.

Q: What happens if I schedule a teleport and the dimension is missing later?

• A: The teleport will be skipped for that player; nothing else is affected.

Installation

1. Place the JAR in your server mods/ folder
2. Run the server on Java 17 and Forge 47.x (MC 1.20.1)
3. Use /op <yourname> to grant yourself permission if needed

Optional: Pre-populate config/ferventes_offline_teleport_exempt.json with UUIDs to skip in bulk actions.
