I understand that you need Unity Pro to develop plugins.
Do you need Unity Pro to use plugins?
What Unity plugins are available?
Thanks.
Yes you need to hav Unity Pro to use Plugins.
Unity Indie does not support them.
I don’t know of any standalone plugin that is offered for sale or download other than the samples and those you find on the unifycommunity.com wiki.
Plugins are commonly used to expand your game with game specific features, not needfully to add “common functionality” that you could or even would offer to other users
Keep in mind that other features are also bound to Unity Pro. Especially anything that requires render textures (movie, post render effects, shadow, reflection, refraction)
If you use a less rigid view of “plugin”, there are plugins that work on Unity Indie (but which are effectively “script packs”). The main difference is that these are more limited in what they could potentially do, e.g. one of these plugins couldn’t access the microphone or a webcam, while a Pro-only plugin written in a language like C++ would be able to.
.NET/Mono assemblies seem to work just fine with Unity Indie. It’s native code plugins that are a no-no.
For instance, integrating the .NET version of my company’s conversational AI system with Unity Indie was almost trivial.
We recently upgraded to pro, but that was mainly for the improved visuals, streaming content, and the ability to have better control over product branding (splash screens, etc).
