Future Development Plans

Beyond the MVP, I have many ideas for enhancing this application, some of which I have listed on the Issues page. My availability to work on these enhancements will depend on various factors. Any contribution is welcome. Please refer to the Contributing Guidelines if you are interested in contributing.

Architecture

The code is centered around the application's state machine implemented using the Stateless libary.

The core idea is that Application fires the application's state machine triggers, and the reamining scripts (such as ARInteractableInstantiator) react to changes of the state.

A similar concept is applied for ARInteractibleStateMachine and its related scripts.
