How do I import mainline campaign units to my campaign?

[tactics123]

I'm interested in importing HttT and UtBS units into my campaign. How do I do just that without copying the whole folder?

Short answer: You don't.

Longer answer: If you want to use units from a mainline campaign, copy everything they need into your add-on's folder. That's the images (obviously), the unit definition files, custom races or movetypes if applicable, and any macros they use for abilities, animations, or the like.

Rationale: If you try to reference files in a mainline campaign from your add-on, there is no guarantee that your add-on will even load on another computer. Wesnoth supports running with the mainline campaigns not installed at all, so those files may or may not exist. (In practice, barring strange circumstances, they will always exist on Windows and Mac installs. Linux installs are more varied – sometimes they are included and sometimes not.)

As a bit more background: some Linux distros prefer to package each campaign separately (ie: scroll down through https://packages.debian.org/search?suit ... snoth-1.16). Normally they'll all get installed anyway, but it's not 100% guaranteed depending on how the user does the installation. Whether you care about supporting that edge case on Linux is up to you.

Wow! Thanks for the heads up.
So the answer is to copy if you want the best support. Understood.
