🌟 StartEffectMod

🧪 A lightweight utility mod that automatically grants potion effects to players when they join the world for the first time.

💡 About

This mod was originally created for our upcoming Calamity Protocol hardcore modpack —
where you get infected right after joining the world and must find a cure within 50 days (50 hours)!
But feel free to use it in your own projects or modpacks.

It simply applies configurable potion effects when a player joins the world,
and can optionally reapply them if removed.
Perfect for mapmakers, servers, or modpack creators who want custom start effects.

⚙️ Features

🎯 Apply any potion effect by ID (e.g. minecraft:night_vision)
⏱️ Custom duration & amplifier values
🔁 Optional “reapply if removed” mode
🧍 “Only once” mode for first join
💀 Optional “keep effect after respawn” and “reset duration on respawn” settings
⚡ Lightweight, server-friendly, and fully configurable

🧰 Configuration

A config file will be generated at:

config/starteffectmod-common.toml

You can modify:

effect → potion effect ID
duration → effect duration in ticks (20 ticks = 1 second)
amplifier → effect strength
onlyOnce → apply only on first login
refillIfRemoved → reapply automatically if lost
keepEffectOnRespawn → keep effect after respawn
resetDurationOnRespawn → reset to full duration when respawning
