Opening craft files on different versions

[Ivan Cheung]

I saw a few crafts on KerbalX but sadly I am currently on 1.4.1 (As Steam Auto updates game and usually ends up ruining the game, and I prefer a stable version) while the craft are built in version beyond 1.4.1

 

is there anyway to modify a craft so it it is compatible with 1.4.1? I installed too many mods that updating the game would take ages to do so.

So long as the parts are still the same, you can go in and edit the craft file & change the version.   Results may vary - the parts Squad has updated since 1.4.1 are "new" parts - so for example, the Mk 2 lander can in pre-1.6 still exists, but post 1.6, the game uses the new Mk 2 lander can. 

AFAIK, the only thing that will happen is you will get a message saying the parts are invalid & the craft won't load, so it's worth a try.

The craft files should look something like this (from one of mine on KerbalX).  Just change the version to 1.4.1.   And maybe delete the "steamPublishedFileID" line - that was added after 1.4

Spoiler

ship = Jet-3
version = 1.7.0
description =
type = SPH
size = 13.0740223,5.09718418,14.1610661
steamPublishedFileId = 0
persistentId = 1757850739
rot = 0,0,0,0
missionFlag = Squad/Flags/REBEL2
vesselType = Debris

This will involve modifying the game, and so the question has been moved to the modding subforum.

Thanks A lot for that and by the way can I delete parts with this method?

[Gargamel]

Do what most of us do.   Keep your stable 1.4 version in one directory, but then install the latest version in another.   This way you can have your cake and eat it too.   And if you then find a craft you must have in your earlier version, you can do the above methods to move it between versions.

It can be done, although if it's a major structural component, it is not going to be easy or pretty.  But if its something simple, it's not hard to do.  Just <Control-F>, find the part you are looking for and delete it out, as well as the lines on other parts where it shows the part you are deleting is attached to other parts.  They will look something like this:

    link = telescopicLadderBay_4289293210

The part section will look like this:

            }

            {
                actionGroup = None
                wasActiveBeforePartWasAdjusted = False
            }
            RetractAction
            {
                actionGroup = None
                wasActiveBeforePartWasAdjusted = False
            }
        }
        UPGRADESAPPLIED

    }
}

So you need to delete out the entire part from the first { to the last }, then delete out the "link =" lines from any parts the deleted part is attached to.  I used the retractable ladder as an example because it happened to be the first linked part of the root part of the craft file I opened to use as an example.  You'll have to find the actual part name either by educated guess or find the part.cfg & looking for the "name =" line
