HPByLevel

HPByLevel is a lightweight, customizable Spigot plugin that dynamically adjusts a player's maximum health based on their current experience level. All level ranges and HP values are fully configurable via config.yml

Features

• Dynamically adjusts max health as a player gains or loses levels
• Supports configurable level ranges (e.g., 0-4, 5-9, 30, etc.)
• Automatically caps current health if it exceeds the new maximum
• Includes commands for:

• Reloading the config without restarting
• Displaying the active HP level configuration

• Includes permission support for both players and admins
• Safe validation: Config errors are caught and logged (invalid configs will not be applied)

Commands

• /hpbl reload

• Reloads the config and reapplies HP hpbl.command.reload or hpbl.admin

• /hpbl info

• Shows the current HP level settings hpbl.command.info

Permissions

• hpbl.command.info

• Allows use of /hpbl info
• Default : true

• hpbl.command.reload

• Allows use of /hpbl reload
• Default : op

• hpbl.admin

• Full access to admin commands
• Default : op

Dev Notes

• You must define the levels section in config.yml; if it's missing or invalid, the plugin will not apply changes and will log an error.
• If /hpbl reload is used with a bad config (bad syntax, missing keys, invalid formats), the system will not overwrite the previous working state.
• You can safely modify and reload config.yml in production without restarting the server.
• Plugin uses Bukkit’s built-in Attribute system — compatible with all standard Minecraft entities.
