Quick Start

• Use this template
• Create jp and global branch from resourceless
• Enable GitHub Actions, manually trigger Update-Global and Update-JP at any branch (they will find the right branch, no matter where you trigger them) to get the first update
• Update-Global will run daily and fails when no update is available, Update-JP won't run automatically

Update-JP Needs to be triggered manually since there isn't a solution to get the latest update json link automatically (maybe there is, but I'm not going to write it now). ba_api in getModelsJapan.py needs to be updated manually (through reverse engineering or network capture) when there is a new update.

About Japan version

The update json link is hard coded into the game OBB resources.

We can get LatestClientVersion from https://prod-noticeindex.bluearchiveyostar.com/prod/index.json, but how the random hash path (likes r48_2q1alt6gvk5igdsj4hl2.json) under yostar-serverinfo.bluearchiveyostar.com is generated?

BA Japan (Yostar) does not have a certain resource path API. And their developers hard code the resource link for a version into the game OBB resources. The game only checks for LatestClientVersion to see if it's outdated and asks the user to update the game from Google Play to get the latest resource link.

Does this mean the user has to update the game from Google Play every month to get the latest monthly in-game activity? -- Yes, this is what's happening. (BA Japan releases an update at Google Play about every month, while BA Global updates about every three months)

You can extract GameMainConfig from game OBB and decrypt it. Check the key ServerInfoDataUrl in GameMainConfig to get the resource link.

Requirements

• decrunch
• fsb5
• lz4
• Pillow
• astc_decomp
• MSVC++ 14.0 Build Tools with Windows 10 SDK

Setup

Building UnityPack

setup.py build

Installing UnityPack

setup.py install

or

setup.py install --user

Downloading Models

py/getModels.py

Downloaded Models located at ./downloaded_resource

Assets (Spine and Audio) located at ./assets

Generating JSON Data

data/audio.json

py/generateAudioJson.py

This will download VOC_JP audio instead of playing it directly (cors issue ?)

To play audio directly from BA's server, change py/generateModelsJson.py

_type = 1

to

_type = 0

data/models.json

py/generateModelsJson.py

And you're done!

Just launch index.html

Used Libraries

• pixi.js
• pixi-spine
• howler.js
• UIKit

Big Kudos for awesome UnityPack
