Skript: Function error on load

When two scripts are loaded, I get this error twice:

[Server thread/ERROR]: #!#! ch.njol.skript.SkriptAPIException: Signature of function is null when return type is asked!

These two scripts rely on functions defined in another script that doesn't seem to be loaded yet. When I reload or enable these scripts afterwards, they load without a problem.

As a workaround, I could either rename these scripts so that they are loaded later, or ignore the errors and force the functions script, on load, to reload the scripts that depend on it. However, I don't like either of these options, as they both seem hack-ish and would make it difficult for me to share my functions script with others. This could also become a mess if I write scripts that rely on functions from more than one script.

I think it would be ideal if functions loaded first. If that's not possible, I suggest implementing optional "import

Function signatures are loaded first, and I just fixed a bug which caused it sometimes not to work. Might fix this :)

Ok, try with dev30. Interested to hear if it got fixed.

Sadly, it doesn't seem fixed. However, I received different errors when I start the server now (for the same scripts that use functions, about the same functions):

Maybe it's possible that the issue is caused by an addon (as the scripts require SkQuery) or another plugin, so I can try editing the scripts and testing on a fresh server later if you like.

ApparitionX picture ApparitionX on 7 Aug 2017

Okay, I went ahead and tried it with two test scripts on a fresh server with Skript as the only plugin:

abc.sk

command /abcIt [<string>]:
    executable by: console
    trigger:
        send test(arg 1) to console

testfunction.sk

function test(s: string) :: string:
    return "abc %{_s}% abc"

It's because of the loading order, put 1_ in the testfunctions.sk name and it'll not throw errors.

Snow-Pyon picture Snow-Pyon on 7 Aug 2017

As a workaround, I could either rename these scripts so that they are loaded later, or ignore the errors and force the functions script, on load, to reload the scripts that depend on it. However, I don't like either of these options, as they both seem hack-ish and would make it difficult for me to share my functions script with others. This could also become a mess if I write scripts that rely on functions from more than one script.

I think it would be ideal if functions loaded first. If that's not possible, I suggest implementing optional "import
