"DCS Witchcraft" is:

• a node.js server application
• a Lua script that runs in the DCS: World mission scripting environment and talks to the node.js server via a TCP connection
• some web applications, including a debug console that allows you to execute Lua snippets inside the running mission and look at the return values

Here's what works so far:

• Lua debug console for interactive development and debugging of mission scripts
• Mission Editor to adjust the positions of existing units (mirrored to the running mission so you can watch the final position in the 3D environment)

Watch the video walkthrough to learn more.

• Copy witchcraft.lua to %USERPROFILE%\Saved Games\DCS\Scripts\ (e.g. C:\Users\<Your Username>\Saved Games\DCS\Scripts\).
• Go to your DCS: World installation directory (most likely C:\Program Files\Eagle Dynamics\DCS World), open the Scripts subfolder and edit the file MissionScripting.lua. Add the following code somewhere before the function sanitizeModule is defined:

witchcraft = {}
witchcraft.host = "localhost"
witchcraft.port = 3001
dofile(lfs.writedir()..[[Scripts\witchcraft.lua]])

To start trying to connect to the node.js server, your mission will have to call witchcraft.start(_G).

Create a new trigger set to fire ONCE, create a new condition TIME IS MORE (1 second) and add two actions:

1. a DO SCRIPT FILE action that loads MIST. Make sure you are using MIST 3.3 or later!
2. a DO SCRIPT action with the text witchcraft.start(_G)

• Start the node.js server. If you are using windows, simply double-click witchcraft.cmd in the windows subfolder of this repository.
• Start your DCS: World mission and enter a slot (singleplayer) or unpause the server (multiplayer).
• Point a web browser at http:https://localhost:3000 (if you used witchcraft.cmd, it automatically did that for you in the first step).

The Lua debug console is mostly self-explanatory. Just play around with it and avoid infinite loops (those will understandably cause DCS to hang).

If you want the map to display the live positions of ground units, you have to tell witchcraft that it should send regular unit updates (select the "enable unit updates" template in the Lua Console and press Ctrl+Enter to execute it). The map is in an early stage and is currently hard-coded to only show units of the blue coalition.
