Sidebar Potion

Lightweight server‑side mod that displays players' active status effects in a clean sidebar. The sidebar auto‑updates and hides itself when you have no effects.

• Server‑only: install on a dedicated server or single‑player integrated server. Clients do not need the mod.
• Configurable: names, colors, potency, icons, and duration format.
• Optional Polymer support: show effect icons using resourcepack.
• Supports vanilla and modded effects (e.g. from Enderscapes - works with polymer port)

Installation

• Put the mod on the server (or your single‑player instance). Clients can stay vanilla.
• Optional: install Polymer on the server to enable effect icons for vanilla clients (see below).

Optional dependency: Polymer

If Polymer is installed on the server:

• Effect icons can be shown to vanilla clients without a client resource pack.
• Set showIcon to true in the config to display icons.
• Set forceCompatIcons to false to use Polymer icons instead of potion icons.

Without Polymer:

• Effect icons will be replaced with colored potion icons.

Configuration

Examples of different configurations

A JSON file is created on first run at:

• ./config/sidebar-potion.json

Edit the file and run /reload to apply changes.

Available options (with defaults):

• showEffectName (boolean, default: true): show the effect name.
• colorizeText (boolean, default: true): colorize lines by effect type.
• hideDefaultGui (boolean, default: true): hide the vanilla potion effect HUD.
• showPotency (boolean, default: true): show effect amplifier (e.g. II, III).
• showIcon (boolean, default: true): show effect icon.
• durationFormat (string, default: "mm:ss"): how effect durations are rendered (see below).
• title (string, default: ""): sidebar title text.
• forceCompatIcons (boolean, default: false): force potion icons even if Polymer is installed.

Duration formats

Use one of the following values:

• "" — no duration
• "t" — ticks
• "s" — seconds
• "s." — seconds.milliseconds
• "mm:ss" — minutes:seconds
• "mm:ss." — minutes:seconds.milliseconds

Behavior:

• The sidebar is removed for a player when they have no active effects.
• The title is taken from title and can be empty.
