DSP Planner Export — BepInEx plugin

A tiny BepInEx plugin for Dyson Sphere Program that serves your live game state over a localhost HTTP server, so the DSP Ultimate Suite planner can show Live mode: your real research progress, plan-vs-actual production rates, and exact blueprint footprints.

The plugin is optional. The planner works fully without it — Live mode just lights up the features that compare the plan to your running factory.

Install

Option A — r2modman / Thunderstore Mod Manager (recommended)

1. Install r2modman (or the Thunderstore app) and select Dyson Sphere Program.
2. Search for DSP Planner Export and click Install (BepInEx is pulled in as a dependency).
3. Start the game from the mod manager.

Option B — manual

1. Install BepInEx 5.x into Dyson Sphere Program (the standard DSP modding setup).
2. Download dsp-planner-plugin.zip from the latest release.
3. Unzip it into your game folder so the DLL lands at …\Dyson Sphere Program\BepInEx\plugins\DSPPlannerExport.dll.
4. Launch the game. The BepInEx console should log: DSP Planner Export: serving http://localhost:8765/state, /protos, /rates

Use it with the planner

Open the planner at https://skieller-software.github.io/dsp-ultimate-suite/ with the game running:

• Research tab → Live: on — repaints the tech trees as you research in-game.
• Planner tab → Plan vs actual → Live: on — compares the plan's per-item rates with what your factories actually produce/consume.
• Mapper tab → Load protos (plugin) — pulls exact model indices, footprints, z-steps and sorter slots for precise blueprint export.

What it serves (localhost:8765)

The HTTP thread never touches Unity objects — the main thread refreshes JSON snapshots ~once per second and the listener serves the latest strings (thread-safe). The page fetches http://localhost from the planner because the plugin sends Access-Control-Allow-Origin: *.

Build from source

CI can't build this (it needs the game's assemblies), so releases are built locally.

Prerequisites: BepInEx 5.x in your DSP install, and the .NET SDK.

dotnet build -c Release -p:DSPManaged="C:\…\Dyson Sphere Program\DSPGAME_Data\Managed"

BepInEx + HarmonyX restore from the official BepInEx NuGet feed (see nuget.config) as compile-time references; the game's BepInEx install provides them at runtime. Only the game-install path is machine-specific — edit DSPManaged in the .csproj or pass it on the command line. Copy bin\Release\DSPPlannerExport.dll into BepInEx\plugins\.

Troubleshooting

• No connection / "no plugin on :8765": make sure DSP is running with the plugin installed; check the BepInEx console for the "serving …" line.
• Listener fails to start: another app may hold port 8765, or Windows needs a URL ACL — change Port in Plugin.cs, or run the game once as administrator.
• /rates counters reset when the plugin reloads; the planner detects the tick going backwards and re-seeds automatically.

Compatibility

Built against DSP on Unity 2022.3 (verified 2026-06). If a future game patch renames an API, the compiler points at the exact spot; the planner side needs no change.
