script resources

Can we use script from tutorials and and forums here and other site and use it for our commercial game project?

because some of the sites make the script ready for download and usage

is it free to use commercially?

the script is from unitycommunity unifycommunity.com is it free to use commercially?

You should contact script’s author for licensing questions.

Sadly there is currently no clear license on the contributions to the wiki (and apparently for this site as well), see e.g. here.

I’d assume though that authors in general intent their code to be in the public domain unless specified otherwise, as you’d assume forum posts containing scripts etc. (why else would someone post that code there in the first place?).
