From time to time, JJ2+ updates to a new version of AngelScript, and a handful of existing scripts can end up breaking as a result. In such cases, if the original authors can't be contacted, should J2O mods/admins reupload those existing scripts so that they can be played again?

For example, Psychomondus straight-up does not compile anymore: the author tried to do something that was never worked to begin with, and at some point AngelScript updated to treat that as a syntax error. The author was last online in November 2022. Should J2O reupload it? Or is that an infringement on the author's rights?

Are there other examples out there besides Psychomondus? Does the number of such uploads, or their popularity, affect the decision? Or how much time has passed since the original upload?

What about (parts of) levels that never worked to begin with, even for reasons other than AngelScript?

I also found one level where AngelScript won't work:

A Generic Single Player Level II

Maybe there will be a solution to fix it.

.
bevore many years, i had in mind to ask the community for help.
i saw the same problem, and ye i do have a script, that lost his compatility
.
to the story:
it was 2013, when i played with zepect, a script that was made by Foly
zepect showed it me, this script changed a few weapons
for example, the seecers, was different, here we saw a purple, bollyship missile
and when the missile exploded, there was a fire ring arround it
and that fire did gone from the center in form of a ring outside
.
i do have a screenshots from that script in action:

.
as i allready told that script dont works anymore, and lost his compatility.
.

Add types to the four arrays, like so:

array returning(32, false);
array boomerangfired(32, false);
array speed(32, cMaxSpeed);
array isfoly(32, false);

and remove the sqrt and abs function definitions altogether.


To be clear, though, the point of this topic was asking whether J2O should fix broken scripts that are uploaded to J2O, not asking how to fix scripts.

thanks so much!!
i tested it,
..and i was able to fix it!
now the script works again
.

i do vote for "yes"
J2O have to fix, broken scripts that are uploaded here
=
im absolutly sure, its also in the interrests of the autors, that there own scripts works fine. (with latest plus)
im sure they dont have anything against it
so i give my yes

100% yes. I think preserving people's work in a playable state is more important than erring on the side of a very unlikely scenario where an author would be angry that their work got a free bugfix.
