Version 2.0 of my battle-tested state-machine tool is online and comes with new features, a new demo and new tutorials!
AssetStore link: https://assetstore.unity.com/packages/slug/122543
This editor tool extends Unity’s built-in state machine - the Animator system. There is no need to learn a fancy new system - just get started as usual with the Animator and integrate a state machine in your workflow as simple as that!
Use your own code base and logic without writing additional scripts. Execute functions from your own MonoBehaviour scripts on Animator states and create a clear structure of your program flow. Make your game/app logic accessable to your whole team by revealing the main dependencies and interfaces in the familiar Animator workspace.
The setup and workflow integration is super easy! You have virtualy no restrictions in using your own scripts and you can plug them into Animator States with just a few clicks.
Simple as that, see it in this tutorial:
You have the coice:
- Setup an overall state-machine to control the main-loop
- Make single entity state-machines, e.g. for AI behaviour or controlling small parts of your application
Any state-machine can operate with sub-state-machines and multiple layers, so the scale of complexity is up to you.
See for yourself in this detailed reworking of the included demo scenario:
