Hotline Example - the modder API for Hotline

🛟 Need help or found a bug? Get support at support.doodesch.de.

A minimal example mod showing how to give your Schedule I mod a panel in the Hotline overlay - a text readout, an action button, a toggle, an optional central hotkey and a log - with a single fluent call. Every call is a zero-overhead no-op when Hotline is not installed, so there is no hard dependency.

What's here

• Hotline.Api/ - the modder shim. Reference Hotline.Api.dll, OR (recommended) drop the single Hotline.cs into your mod and compile it in - no extra DLL to ship.
• HotlineExample/ - the example mod (Core.cs): registers a panel and demonstrates the full surface.

The 10-second version

using Hotline.Api;

Hud.RegisterPanel("MyMod", "My Mod")
   .Text(() => "queue = " + _queue.Count)                // a free, multi-line readout
   .Action("Reload", Reload)                             // a button (replaces a debug hotkey)
   .Toggle("Verbose", () => _verbose, v => _verbose = v) // an on/off control
   .Hotkey("Reload", HotlineKey.F8, Reload)              // an optional central hotkey
   .Log();                                               // a log channel

That is it - no OnGUI, no uGUI, no per-mod hotkey. Hotline draws the window; the player presses its master key (F6) to open the overlay and your panel is there alongside every other mod's. See HotlineExample/Core.cs for the working version, and the Hotline wiki for the full API.

Integration

• Copy-in source (recommended): drop Hotline.Api/Hotline.cs into your mod project and compile it in. Nothing extra to ship; it binds to the running Hotline host by reflection and is a no-op when Hotline is absent.
• Reference the DLL: reference Hotline.Api.dll.

Either way it works regardless of load order (registrations queue until the host is up) and adds no hard dependency. If your mod already polls a raw function key, Hotline also auto-detects it and adds it as a button to your panel - but registering a panel like this is the clean way.
