Rejoin Scheduler (Catporter utilities)
Rejoin Scheduler adds a command that makes you disconnect and automatically reconnect after a specified time.
About this Mod
Rejoin Scheduler lets you automatically reconnect to a server after a specified delay, putting you in control of exactly when you return. It’s lightweight and entirely client-side.
You can set a custom delay using commands, or create and manage named presets for different scenarios.
Commands like /rejoin delay, /rejoin preset set, and /rejoin with allow you to quickly configure and schedule your reconnects without any server-side setup.
Rejoin Schedulers is designed to work in tandem with Catporters, a system where a cat entity tracks your connection. If you've been offline for a specific window—say, between 10 and 20 seconds—and rejoin within that time, the cat will teleport you as intended. This mod ensures you can reliably hit that timing window, making Catporter mechanics easier to trigger and more consistent.
Commands:
/rejoin delay {ticks} - Disconnects the player and rejoins after the specified amount of time has passed.
/rejoin preset set {name} {delay} - Adds a preset with the specified delay.
/rejoin with {preset} - Rejoins with a delay specified by /rejoin preset set {name} {delay}
/rejoin preset list - Lists all presets and their delays in ticks.
/rejoin preset delete {preset} - Deletes the specified preset.
Do note: 20 ticks is 1 second, so if you want to rejoin in 15 seconds, you should do 20x15 to get the amount of ticks (300 ticks).
Presets are stored in a json file in the config folder.
