What does the Action State Parameter in the Animator do?

[justsomedev]

Hello everyone! In the animator there's a parameter titled ActionState. What is it and what does the parameter do when you use it as a transition condition? I looked at the shooter and melee documentation and I don't see it anywhere. If I missed it somewhere any pointers will be greatly appreciated.

You can use it to manipulate more complex actions, for example, in the Swimming add-on we use it to identify the swimming states like swimming up, down, inside water, above water, etc... this helps on managing the transitions easier.

An alternative to it is using vAnimatorTags, it's also really helpful to idenfity states and handle things internally in the code
