Traffic Editor III

Welcome to Traffic Editor III.

install stuff

Unfortunately we need a newer Rust than what comes with Ubuntu 20.04.

First make sure you don't have any distro-installed Rust stuff on your machine:

sudo apt remove rustc cargo

If you don't have it already, install rustup from the Rust website: https://www.rust-lang.org/tools/install

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Just select the normal defaults (option 1). A bunch of stuff will happen. Be sure to reload your ~/.bashrc afterwards or close and re-open your terminal.

Alternatively, if you already have a Rust installation managed by rustup, you can just do this to bring it up-to-date: rustup update

Next, install some dependencies and the source:

sudo apt install lld libxcb-shape0-dev libxcb-xfixes0-dev binaryen
git clone ssh://[email protected]/open-rmf/traffic_editor_iii
cd traffic_editor_iii
cargo build --release

Dependencies.... still figuring this out, and it's changing daily, but currently as siblings to this repo:

bevy from https://github.com/mrk-its/bevy on branch wgpu-0.11 only changes are to remove the local wgpu crates-io patch and the wgpu log filter in line 78 of crates/bevy_log/src/lib.rs to error to avoid debugging console text
bevy_egui from https://github.com/jakobhellermann/bevy_egui on branch bevy-pipelined with a few tweaks to Cargo.toml to point at the local bevy sibling path and add render to the feature list. Not sure if that is needed. Specifically drop in this line: bevy = { path = "../bevy", default-features = false, features = [

run stuff

cargo run --release

WASM stuff

Dependencies:

cargo install wasm-bindgen-cli
cargo install basic-http-server

At time of writing, the latest wgpu (v0.11) can support WebGL2. At time of writing, this requires the local clones and slight tweaks to the forks described above, but once this is setup, it's quite magical:

cargo build --target wasm32-unknown-unknown --release
wasm-bindgen --target web --out-dir web target/wasm32-unknown-unknown/release/libtraffic_editor_iii.wasm
cd web
basic-http-server . -a 127.0.0.1:1234
