Hexagon tile-based terrain generation system. A series of configurable algorithsm can generated varied and realistic terrain.

Usage

Want to use Terra? It has a native Rust interface, as well as a WebAssembly interface. View the code in demo/ for an example of how to create Terra configs and generate worlds from Wasm.

Development

Prerequisites

• rustup
• wasm-pack
• npm

Running the Demo

There is a minimal in-browser demo that's very useful for development.

cd demo
npm install
npm run start

This will build the project and start an HTTP server on http://localhost:3000.

Deployment

Deployed through GitHub pages. Any push to master will trigger the CI to rebuild, which will updated the deployment.

Rust Nightly

Currently we use Rust nightly because of a handful of features. Once this list gets down to zero, we can switch to stable.

• rustc
  • const_fn_floating_point_arithmetic
• rustfmt
  • imports_granularity
  • wrap_comments

Troubleshooting

ARM + wasm-pack

If you're running on a Mac M1 or any other ARM system and get this error when trying to run the demo:

Error: no prebuilt wasm-opt binaries are available for this platform: Unrecognized target!
To disable `wasm-opt`, add `wasm-opt = false` to your package metadata in your `Cargo.toml`

Then make sure your installation of wasm-pack is at least version 0.10.2. You can check with:

wasm-pack --version

You can upgrade by reinstalling with the link above.
