PackStacker

PackStacker is a simple resource management plugin intended for "stacking" packs on minecraft clients. Downloads can be found at releases.

Short Guide

Resource packs are defined through ".pack" files. Navigate to PackStacker/packs/ under your servers plugins folder.

To define a pack, create a file with the extension .pack under the packs folder. (i.e example.pack)

Pack files follow yaml syntax. See below for an example .pack file.

name: "MvndiPack"
url: "https://github.com/HydrolienF/MvndiPack/releases/download/1.20.6.425/MvndiPack.zip"
hash: "D64DCFA57B5A94383FA39F32BE3B6D38D853304C"
priority: 0
required: true
prompt: "Hello <rainbow>world</rainbow>."
load_on_join: true

Required Pack Options

name The name of the pack. No two packs can have the same name. Pack names MUST be unique.
url The url to the pack. This url must be a direct download link. Typically, these links end in the file format .zip.
hash The SHA1 hash of the pack. You can obtain this by running certutil -hashfile "filename.exe" SHA1 on Windows.

Optional Pack Options

priority A number value corresponding to which order this pack will manifest. A lower number means the pack will be on a "lower" level on the client. Default: 0 (no priority)
required Whether or not to kick the client if the player refuses the pack. Default: false
prompt A MiniMessage compatible string that users will be prompted with when a pack is requested to the client. Default: no prompt (null)
load_on_join Whether or not to prompt the user this pack on join. Default: false
