I found the packaging part to be easy. I can further explain it to you if you'd like.
Actually I just re-accepted the challenge with a slightly more focused mind than last time and worked it out, with the assistance of a tutorial which I naturally used as a loose reference then disobeyed
I can now build the project, receive
only my files (instead of having to separate them from the entirety of the Minecraft source) and get them to be packaged.
Now I'm looking into some sort of script I can have Eclipse automatically run when I build, so I can make it package the files, copy it to the test client's mods folder and run the test client. Because I don't code unless I code
swag.
Then I gotta learn about coding it to be server and client compliant and whatnot, probably gonna stare blankly at the InfiCraft source until I absorb that secret from it
