WorldTimer

WorldTimer

A Paper 1.20.1 plugin that enforces configurable time limits for specific worlds (e.g., resource worlds) with rank-based overrides via LuckPerms.

Features

• Per-world time limits — Configure how long players can stay in each world
• Rank-based overrides — Different ranks get different time limits and cooldowns via LuckPerms permissions
• Cooldown system — Players must wait before re-entering a world after their time expires
• Warning messages — Configurable warnings at specific time thresholds
• Expiry actions — Run commands when a player's time expires (e.g., titles, effects)
• Return teleport — Players are teleported back to their exact pre-entry location
• Persistent storage — SQLite database survives restarts and crashes
• Bypass permission — Staff can bypass all restrictions per-world

Requirements

• Paper 1.20.1+ (or compatible fork)
• Java 17+

Optional Dependencies

• LuckPerms — For permission-based time limits and cooldowns. Without it, all players use the default values from config.
• Multiverse-Core — Works seamlessly with Multiverse-managed worlds

Installation

1. Download the latest world-timer-x.x.jar from releases
2. Place it in your server's plugins/ folder
3. Restart the server
4. Edit plugins/WorldTimer/config.yml to configure your worlds
5. Reload with /worldtimer reload

Configuration

# How often the plugin checks timers (in seconds)
tick-seconds: 1

storage:
  type: sqlite

messages:
  prefix: "&8[&bWorldTimer&8] &r"
  warn: "&eYou have &6%time_remaining% &eremaining in &6%world%&e."
  expired: "&cYour time in &6%world% &chas expired."
  cooldown: "&cYou must wait &6%cooldown_remaining% &cbefore re-entering &6%world%&c."

worlds:
  resource:                              # World name (case-insensitive)
    enabled: true
    main-world: "survival"               # Fallback teleport world
    teleport-location: "spawn"           # Currently uses return point or spawn
    default-limit-seconds: 1800          # 30 minutes (used if no permission)
    default-cooldown-seconds: 600        # 10 minutes (used if no permission)
    limit-permission-prefix: "worldtimer.limit.resource."
    cooldown-permission-prefix: "worldtimer.cooldown.resource."
    bypass-permission: "worldtimer.bypass.resource"
    warn-at-seconds: [600, 300, 60, 10]  # Warn at 10m, 5m, 1m, 10s remaining
    expire-commands:
      - "title %player% title {\"text\":\"Time is up!\",\"color\":\"red\"}"

Permissions

Time Limit Permissions

Format: worldtimer.limit.<world>.<duration>

Duration formats: 30s, 30m, 2h, 1d, unlimited

If a player has multiple limit permissions, the highest value is used.

Cooldown Permissions

Format: worldtimer.cooldown.<world>.<duration>

If a player has multiple cooldown permissions, the highest value is used.

Other Permissions

Commands

Alias: /wt

How It Works

Entry Flow

1. Player teleports to a configured world
2. Plugin checks for bypass permission → if present, allow freely
3. Plugin checks for active cooldown → if active, block entry and show message
4. Plugin saves the player's current location as their return point
5. Plugin resolves time limit from permissions (or uses default)
6. Timer tracking begins

While In World

• Timer increments every tick interval
• Warnings are sent at configured thresholds
• Time is tracked per-player per-world

On Expiry

1. Expiry message is sent
2. Configured expire-commands are executed
3. Cooldown begins (based on permissions or default)
4. Player is teleported back to their saved return point
5. If no return point exists, player goes to main world spawn

Disconnect Safety

• If a player disconnects while in a limited world, their timer is saved
• On rejoin, if their timer is expired or cooldown is active, they're teleported to safety
• This prevents bypassing limits by disconnecting or switching servers

LuckPerms Setup Example

# Default rank: 30 minute limit, 10 minute cooldown
/lp group default permission set worldtimer.limit.resource.30m true
/lp group default permission set worldtimer.cooldown.resource.10m true

# VIP rank: 1 hour limit, 5 minute cooldown
/lp group vip permission set worldtimer.limit.resource.1h true
/lp group vip permission set worldtimer.cooldown.resource.5m true

# MVP rank: 2 hour limit, no cooldown
/lp group mvp permission set worldtimer.limit.resource.2h true
/lp group mvp permission set worldtimer.cooldown.resource.0s true

# Staff: bypass all restrictions
/lp group staff permission set worldtimer.bypass.resource true

Without LuckPerms

If LuckPerms is not installed, the plugin still works:

• All players use default-limit-seconds from config
• All players use default-cooldown-seconds from config
• Bypass permissions still work via Bukkit's permission system
• A warning is logged on startup

Storage

Data is stored in plugins/WorldTimer/data.db (SQLite):

• timer_data — Per-player per-world: seconds used, cooldown timestamp
• player_worlds — Last known world for each player
• return_locations — Saved return points (world, x, y, z, yaw, pitch)

Placeholders

Available in messages:

• %player% — Player name
• %world% — World name
• %time_remaining% — Formatted time remaining (e.g., "5m 30s")
• %cooldown_remaining% — Formatted cooldown remaining

Building
