HOW IT WORKS
Saving player progress
The cloud-save system in my April 2025 article uses Udon# in the world, a Go/Echo API, and MariaDB for storage. It saves and loads player progress, and provides data for rankings and statistics.
- VRChat / Udon#Create a signed URL from the play data. The player enters it to send a request.
- Go / EchoVerify the signature and handle save and load requests.
- MariaDBStore play data for loading, rankings, and statistics.
HOW IT WORKS
Signed URLs for save requests
VRChat’s networking restrictions shaped the design. The Udon# client creates a signed URL, which the player enters to send a GET request. The Go API checks the signature before saving or loading data. The article describes the implementation at the time.
