HEXROLL 3

This is the new work-in-progress version of HEXROLL (https://hexroll.app) - the OSR sandbox generator.

Currently Included

• hexroll3-scroll: the core content generator
• hexroll3-scroll-data: the new data model, based on the hexroll2e model
• hexroll3-app: The hexroll3 app
• hexroll3-testbed: an egui application for testing and messing around
• hexroll3-signaling: the VTT signaling server

Running the testbed

Make sure you have git and an up-to-date Rust development environment, and then:

git clone https://github.com/hexroll/hexroll3 && cd hexroll3
cargo run --release

This should open up the testbed where you can generate your first sandbox:
