Start Effect

Mod to specify the effect when the player first enters, with configuration options

🌟 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


🧾 License
