Getting Started

This guide assumes a Windows machine with Cities: Skylines 1 installed through Steam.

Requirements

• Cities: Skylines 1.
• PowerShell.
• .NET Framework compiler tools available through Windows.
• CS1 managed assemblies under the game install directory.

The default build script expects the game at:

D:\SteamLibrary\steamapps\common\Cities_Skylines

If your install path is different, edit scripts/build.ps1 before building.

Build and Install

From the repository root:

powershell -NoProfile -ExecutionPolicy Bypass -File .\scripts\build.ps1

The script compiles SkylinesAgentBridge.dll and copies it into:

%LOCALAPPDATA%\Colossal Order\Cities_Skylines\Addons\Mods\SkylinesAgentBridge

Enable the mod in the CS1 content manager before loading a city.

Resume a City

The normal loop starts from the latest local save:

powershell -NoProfile -ExecutionPolicy Bypass -File .\scripts\start-resume.ps1

The script builds the mod unless -SkipBuild is passed, launches CS1 through Steam, clicks the launcher Resume button, and waits for the local API.

Start a Fresh Map

For clean experiments:

powershell -NoProfile -ExecutionPolicy Bypass -File .\scripts\start-new-map.ps1

Useful flags:

powershell -NoProfile -ExecutionPolicy Bypass -File .\scripts\start-new-map.ps1 -SkipBuild
powershell -NoProfile -ExecutionPolicy Bypass -File .\scripts\start-new-map.ps1 -SkipNewMap

Verify the Bridge

Once a city is loaded:

Invoke-RestMethod http://127.0.0.1:32123/health
Invoke-RestMethod http://127.0.0.1:32123/state/summary

Use scripts/smoke-test.ps1 for a broader read and dry-run command check.
