So, for those of you looking to use TACLS in the KSP 1.1 release, I've actually re-compiled it for KSP 1.1 and made a couple small modifications to match the new API. It's not well tested, but it pretty much just seems to work for me. It still doesn't use the stock toolbar, since that's a lot more work. A posted an issue on GItHub offering to post a Pull Request but I haven't gotten any response. For those of you wanting to use it in the meantime, drop the two files in here into GameData/ThunderAeroSpace/TacLifeSupport/ AFTER you've already installed the latest version of it. I'm going to give the author, taraniselsu, another two weeks or so to respond to the issue and if I don't get a response, I'll fork the repository and publish my own version. The reason why I haven't already done this is already is as follows: taraniselsu uses an 'unconventional' tooling setup in order to build TACLS and I had to build a whole new set of project files in order to get it to build on my development environment. If they intend to get back to TACLS and continue work on it, presumably they will want to continue using their own custom tooling and so therefore I would leave all of that alone when I submit the pull request and only include the changed .cs files. Anyway, we'll see what happens.
USE AT YOUR OWN RISK: Download Hacked-For-1.1 Version Here
Once again:
Install TACLS, the latest released official version, from wherever you do that.
Download that zip file.
Unzip it. You will have CommonReferences.dll and TacLifeSupport.dll
Put those into the GameData/ThunderAeroSpace/TacLifeSupport/ directory, overwriting what's needed
I do not offer any support or anything for this. I am not the author of this work. The source code is unchanged except for the bare minimum to make it work in KSP 1.1. I am distributing this in accordance with the author's license, which is available here current as of Jul 28, 2013. I do not intent to take over maintaining this mod if I do not hear from the author, though I may attempt to re-publish something (with source code) that works so that somebody else can work on it afterwards.
