Licensing Question

(ReiKGT) #1

Hey I recently decided to jump from AS3 to C#. I’ve been deconstructing some of the FP classes like the Entity and World classes and remaking them in C#. I’m not trying to port the entire library or even the entire class, but I am basically copying some of the functions.

What kind of Licensing restrictions would I be subject to? Or would there be any at all? I’m only remaking about 1/3 of each class, just the stuff I find useful.

PS, sorry if this wasn’t the right section. I looked at Meta, and that didn’t seem to fit. Then I looked at Creations and it seemed even less relevant, so I ended up here.

As far as I know Flashpunk doesn’t include a license at all. There have been a few ports to different languages and backends and nobody has ever had a problem with them.

If you’re moving to C#, you might want to take a look at my port #Punk. It’s a work in progress but we’ve been using it for a while without any serious issues.

Thanks for the advice but I probably won’t use the vast majority of the FP features. I’ve just become really comfortable with the World -> Entity -> Graphic structure. I’ve already converted over most of what I need anyway and it seems to work fine.

Also I looked at the git and there is a licensing agreement. It’s only real restriction is that I include a txt of the license with “all copies or substantial portions of the Software.” So that’s kind of vague in how it would affect me. It’s not a direct copy, and “substantial” is very ambiguous.

A port is a “copy” and “substantial” is an ambiguous term, however, the only requirement of the license is that you give credit and include the text of the license in all copies that you distribute. If including the license is too much of a problem for you, you can check with the original authors whether your usage exempts you from crediting them or if they are willing to make an exception for you before you continue.

When ChevyRay was still active on the forums (old flashpunk website), he never really seemed to make a big deal about giving FlashPunk credit.

That being said, it’s the thought that counts.

With that said, I can also say that Chevy hasn’t really cared about ports. Just include some kind of credit out of common courtesy. :smile:

Actually, thanks a ton man. I’m learning quite a bit from this. I wasn’t really exploiting the benefits of C# at all.
