MiningFatigue3Fix

Fixed the issue of abnormal mining speed in Mining Fatigue III (MC-279819).

The original version only officially fixed this issue in 26.3, and this plugin provides a temporary fix for versions prior to 26.3.

Problem description

When the excavation fatigue level was upgraded from Level II to Level III, the speed multiplier erroneously used 0.03 instead of 0.3, resulting in:

This plugin corrects the incorrect speed to the correct value by temporarily adding the BLOCK_BREAK_SPEED attribute modifier.

Functional Features

• Automatically adjust the mining speed of players with Mining Fatigue III
• Supports on/off commands, allowing for instant activation/deactivation
• The switch status is saved persistently, ensuring it is not lost upon restart
• Lightweight design, with almost no performance impact
• Only affects Excavation Fatigue III, and does not affect other levels

Environmental requirements

• Minecraft 1.20.5 ~ 26.2
• Core Paper / Spigot / Purpur, etc. (as long as they support Bukkit API)
• Java 21 or higher (26.x requires Java 25)

Installation method

1. Download the latest version of MiningFatigue3Fix-x.x.x.jar
2. Place it in the plugins folder of the server
3. Restart the server

Instructions

The default permission is op.

Working principle

When the player has Excavation Fatigue III (amplifier = 2), the plugin will add a MULTIPLY_SCALAR_1 attribute modifier to multiply the excavation speed by 10, thereby correcting the error from 0.0027 to the correct 0.027.

When the effect disappears or the plugin is closed, the modifier will be automatically removed.

The switch state is saved in config.yml and remains valid after restarting the server.

Precautions

• Only supports Minecraft 1.20.5 ~ 26.2 (requires the BLOCK_BREAK_SPEED attribute)
• After updating the server to version 26.3 or later, the original version has already fixed this issue, so you can directly uninstall this plugin
• Versions 1.20.4 and earlier cannot use this plugin due to the lack of relevant attributes
