dcs-http

dcs-http is a Play! framework 1.x application that exposes a small JSON HTTP API with data from a DCS World client.

Demo

Here's a demo what you can build with this!

Features

The API currently exposes two endpoints:

Fetch all objects (static and dynamic) in the simulator: /api/objects

Fetch all active objects (objects that are moving): /api/activeobjects

Example response

[

    "groupName": "AWACS #001",
    "entity": "O",
    "time": 9776.44
  },
  {
    "id": 17018369,
    "name": "Tanker SHELL-1",
    "lat": 41.896175,
    "lon": 42.170345,
    "heading": 0.13528,
    "alt": 5486.398435,
    "country": "Enemies",
    "type": "KC-135",
    "groupName": "Tanker SHELL-1",
    "entity": "O",
    "time": 9776.44
  }
]

Example client

There currently exists a sample client which is located at http://localhost:9000/maps. This is a small web page that uses JavaScript to fetch the positions of all objects in the game which are then drawn out on a map.

How it works

DCS World allows you to run Lua code in order to export data out of the simulator. Lua is used in order to establish a socket to the Play application, where data is then streamed. The data is cached in memory in order to efficiently serve HTTP requests to clients.

TODO

Expose much more information from DCS - the active players on the server, the current map and so on. If you know Lua or DCS World, please get in touch.

Run it yourself

If you'd like to run the application yourself, you're welcome to do so.

Install DCS World.
If the folder doesn't exist, create a folder called Scripts in %USERPROFILE%\Saved Games\DCS\
Copy lua/Export.lua from the root of this repo to %USERPROFILE%\Saved Games\DCS\Scripts
Install JDK 7
Install Play framework 1.x. Instructions here.
Clone this repo, git clone git://github.com/Peksa/dcs-http.git
Start the application, play run --%prod
Start DCS World and join or host a single or multiplayer game.
Visit http://localhost:9000/api/objects or try out the sample client at http://localhost:9000/maps
