A/B Street Instructions

General disclaimer: This is a very rough demo. The user interface is clunky, and gameplay is not cohesively tied together yet. Please email dabreegster@gmail.com or file a Github issue if you hit problems.

Installing the game

Grab a pre-built binary release -- updated every Sunday, announced at r/abstreet:

• Windows: https://github.com/dabreegster/abstreet/releases/download/v0.1.23/abstreet_windows_v0_1_23.zip
• Mac: https://github.com/dabreegster/abstreet/releases/download/v0.1.23/abstreet_mac_v0_1_23.zip
  • The minimap may be missing, depending on your monitor's DPI. If so, modify the play_abstreet.sh script to pass --hidpi_factor=2.0 and experiment with different values. If you have to do this, please file an issue and let me know, so I can figure out why glutin misreports this.
• Linux: https://github.com/dabreegster/abstreet/releases/download/v0.1.23/abstreet_linux_v0_1_23.zip

Unzip the folder, then run play_abstreet.sh or play_abstreet.bat. On Windows, you'll probably get a warning about running software from an unknown publisher.

Or you can build from source.

Playing the game

General controls:

• Click and drag to move
• Scroll wheel or touchpad to zoom
• Menus should work as expected. Most actions have a keybinding.
• You can hover over an object and left-click to see more actions.

Things to try:

• In sandbox mode, hover over an intersection, right click, and spawn agents.
• To run a realistic, full day's worth of traffic, go to sandbox mode, then "start a scenario" (hotkey s) and choose the "weekday_typical_traffic" entry. Time (shown in the top-right corner) starts at midnight. Things tend to get interesting around 6am -- use the speed controls in the top-left. Try zooming in for details, and zooming out to see an overview.
  • The full scenario should complete successfully on the small montlake map. On other maps, it currently gridlocks or crashes. Most of these are known issues.
• Go to edit mode (note this will reset the simulation). Use the buttons at the top to pick a lane type, then hover over a lane and press space to change it. Deselect the lane tool, then click an intersection to edit stop signs or traffic signals.
• Go back to the main menu and pick a challenge. Eventually these will be very self-guided, but there are various problems with all of them right now.
