This is a DFHack plugin which allows items AND units that fall on top of minecarts to be loaded into them. The plugin has been tested on 44.12, 47.03, and 47.04, but probably works on other versions that are not drastically different from those.

Installation:

Attached is a zip containing the source file and two subfolders. Start by unzipping it. If you:
* Have a 64-bit Windows system,
* Are using DF version 0.47.03 or 0.47.04, and
* Have DFHack installed for either of those versions (the pre-built downloads are fine here),
then you merely need to move the file "minecart_fall_loading.plug.dll" file inside the subfolder corresponding to your version to
<df folder>/hack/plugins.

Otherwise, you must compile this plugin with DFHack. Instructions for compiling DFHack are here. Once you pull from the DFHack repo, stick the unzipped source file in dfhack/plugins, add

DFHACK_PLUGIN(minecart_fall_loading minecart_fall_loading.cpp)

in dfhack/plugins/CMakeLists.txt next to the similar lines, and then follow the usual instructions for building DFHack.



Zip structure:
