PRAGMATA Split Control (Two-Player Co-op Mod)

Read this in other languages: Русский

A local two-player co-op mod for PRAGMATA (Steam version 1.2.2.0+).

This mod enables local split-control co-op on a single PC:

• Player 1 (Hugh): Full control over movement, combat, camera, and target selection.
• Player 2 (Diana): Uses a second controller to solve hacking mini-games and puzzles (Y/X/A/B or ▲/■/X/●).

Architecture & How Input Isolation Works

RE Engine natively merges input from all connected controllers into a single combined device. To separate controls, this mod consists of three components:

1. Native Input Filter (native/PragmataInputFilter.cpp):

   • Hooks XINPUT1_4.dll functions inside PRAGMATA.exe.
   • Isolates controllers so the game engine only sees Player 1's gamepad while Player 2's inputs are intercepted.
   • Keyboard and mouse input is never filtered and always remains available to Player 1.

2. C# REFramework Plugin (managed/PragmataSplitControl/):

   • Reads Player 2's controller via XINPUT9_1_0.dll.
   • Passes Player 2's hacking directional commands directly into active in-game puzzles.
   • Automatically falls back control to Player 1 if Player 2's controller disconnects.

3. Configurator Utility (tools/PragmataSplitControlConfigurator.cs):

   • WinForms application for easy controller slot assignment and live input testing.

• DualSense / DUALSHOCK 4 (Native HID) for P1 + Xbox/XInput for P2 (Recommended to retain DualSense adaptive triggers).
• Two Xbox / XInput Controllers.
• Keyboard & Mouse for P1 + XInput Controller for P2.
