License on using PrimeTween in a commercial game template

[suppayami]

Hello PrimeTween team,

I'm working on a commercial Unity game template and want to use PrimeTween. As I read the license, this might fall into making a library that depends on PrimeTween; however, the forum post link doesn't point to the correct post in the thread.

I want to ask if using PrimeTween in a commercial Unity game template is possible, and if yes, how I can do that legal-wise.

Thank you!

Hey,

While including PrimeTween inside a paid template sounds good to me, I'm afraid this may open the gate for other products that add minimal functionality to PrimeTween and then sell it at a price.

I'm currently exploring ways to install the plugin via Unity Package Manager via NPM or OpenUPM without importing it from Asset Store. This will unblock use cases like yours, and other projects will be able to depend on PrimeTween without redistributing its source code along the way.

Thank you for your answer.

So if I understand correctly, for now, as long as we won't distribute PrimeTween along the template, it would be okay? For example we can ask user to opt-in PrimeTween by adding it manually from Asset Store.

Would love to hear more about NPM/OpenUPM solutions when it's ready too 😁

Yes, it's okay if you ask your users to install PrimeTween manually from Asset Store.

I just uploaded PrimeTween to npm, and it seems to work as I expected. Here is the installation process:
Add a scoped registry to Packages/manifest.json file:

"scopedRegistries": [
  {
    "name": "npm",
    "url": "https://registry.npmjs.org/",
    "scopes": [
      "com.kyrylokuzyk"
    ]
  }
]

Then add this line to the dependencies section:

    "com.kyrylokuzyk.primetween": "1.3.0",

Please tell me if this works for you. I'll update the license file soon to reflect that it's now allowed to install PrimeTween via npm.

Thank you, it works perfectly! 😁
