# A/B Street Instructions

General disclaimer: This is a very rough demo. The user interface and controls
are horrible. Don't expect things to work well, or at all. Please email
`dabreegster@gmail.com` or file a Github issue if you hit problems.

## Installing the game

The easiest method is to use pre-built binaries. Check
https://github.com/dabreegster/abstreet/releases for the latest version, though
I'll try to keep these links up-to-date:

- Windows:
  https://github.com/dabreegster/abstreet/releases/download/v0.1.1/abstreet_windows.zip
- Mac:
  https://github.com/dabreegster/abstreet/releases/download/v0.1.1/abstreet_mac.zip
- Linux:
  https://github.com/dabreegster/abstreet/releases/download/v0.1.1/abstreet_linux.zip

The Windows and Mac versions may have more problems than the Linux version,
because I only have regular access to a Linux machine.

### Compiling from source

To build, you need a Linux-like environment with `bash`, `wget`, `unzip`, etc.
You also `osmosis` for the import script. At runtime if you want to use the
screen-capture plugin, you need `scrot`.

1.  Install Rust, at least 1.31. https://www.rust-lang.org/tools/install

2.  Download the repository:
    `git clone https://github.com/dabreegster/abstreet.git`

3.  Download all input data and build maps. Compilation times will be very slow
    at first. `cd abstreet; ./import.sh && ./precompute.sh --release`

If you build from source, you won't have the convenient launcher scripts
referenced below. Instead:

```
cd editor
cargo run --release ../data/maps/montlake.abst
```

## Running the game

Start the game by running `play_abstreet.sh` or `play_abstreet.bat`. On Windows,
you'll probably get a warning about running software from an unknown publisher.

General controls:

- Click and drag to move
- Scroll wheel or touchpad to zoom
- Hover over something and hold Control to examine it
- Select something and right click for a menu of relevant actions. The keyboard
  shortcuts also work just by selecting that object.
- Explore the menu bar at the top.

Simulating traffic:

- Choose `seed the sim with agents` from the `Simulation` menu, or just press
  `s` while nothing is selected. This will spawn a bunch of parked cars, buses,
  and pedestrians leaving buildings. Some of the pedestrians will get into a
  parked car and start driving somewhere.
- Press `space` to pause/resume the simulation. `]` speeds things up, and `[`
  slows things down. You can find all of these in the `Simulation` menu.
- Spawn a single agent by selecting the starting building and pressing `F3` (or
  right clicking the building and using the menu). Select the goal building and
  confirm with `F3`. You can hover over any agent to see its route; press `r`
  (or right-click the agent) to keep drawing the route.
- Hover over an intersection and press `z` to spawn a bunch of cars nearby.

Editing the map:

- You can only make edits when a simulation isn't running. If you already
  started one, quit and start over.
- Select an intersection and press `e`. You can then select an individual turn
  icon and press `space` to change its priority.
- Enable `edit roads` from the `Edit` menu, select a lane, and press `space` to
  change its type.
- Save your changes using `manage map edits` in the `Edit` menu.
