An unreal engine plugin with an embedded HTTP server to do your bidding.

Install this plugin like any other UE4 plugin. Once this is done, the plugin will host a HTTP server at port 18820.

All these endpoints will trigger the subsequent functionality in the engine. There is never a request body expected, and only the 200 status code indicates a success.

Post body is expected to be a string. The body is passed directly to the UE4 editor console where it is Exec'd.

Example: Run a python script in the scripts dir called foo.py with arguments a, b and 42:

echo "py.exec_args foo.py a b 42" | http POST localhost:18820/command

Example: Run a random UE4 engine console command:

echo "showfps" | http POST localhost:18820/command

Post body is expected to be a comma-separated-string. The first element is the path in the local file-system to the .pak file we wish to mount, and the second argument is the mount path.

Eample: Mount /tmp/foo.pak into /Content/Import/02843684:

echo /tmp/foo.pak,/Content/Import/02843684 | http POST localhost:18820/loadpak

The /loadpak endpoint will also accept HTTP POST payloads with JSON where the following keys are expected to live:

{
    pak_path: <...>,        // Path to pak file in the local system
    mount_point: <...>,     // Game mount point
}

The JSON deserializer is attempted first, failing which the payload is checked against the csv scheme.

echo "py.exec_args import_fbx.py import_shapenet /tmp/shapenet/ 00000001" | http POST localhost:18820/command
echo "py.exec_args import_fbx.py make_pak /Game/Import/ /tmp/output.pak" | http POST localhost:18820/command
echo "/tmp/output.pak,/Content/Import/02843684" | http POST localhost:18820/loadpak
