[Feature Request] States that use tasks instead of Coroutines

[TdXYZ]

Starting from Unity 2023.1, there is now an Awaitable class that makes it possible to use async/await functionality. It may be beneficial to add a sort of TaskState as an alternative to the CoState, as TaskStates could get around some of the limitations such as not being able to use lambdas,

Hi @TdXYZ,
thanks for the feature request!

I didn't know about the Awaitable feature in the latest versions of Unity. Your proposal to have a new state class that works with Awaitable is a good idea!
As I'm quite close to releasing version 2.1, I'll implement it in the next version of UnityHFSM. By using C# preprocessor directives, I intend to stay compatible with older versions of Unity while also supporting the latest features.
I'll keep this issue open until I have implemented it.

@Inspiaaa is this something that you are open to contributions for? if so, would you also be open to extending the feature to support unitask via preprocessor directives as well?

Hi @jasonpanosso, yes, I would definitely appreciate contributions in this area! My only main requirement is that the project stays fully compatible out-of-the-box for users who don't use UniTask. As long as the implementation is optional and doesn't introduce breaking changes or forced dependencies, I'm all for it! Feel free to open a PR.
