Checking input and applying it?

[Shadowblitz16]

How do I check input and apply it via behavior trees?

I don't know how I would compound actions into things like axes and vectors

Any node has an _input method you could hook into. Since actions are nodes, you can do it on your custom action like so:

var event

func _input(event):
   this.event = event

func tick(actor, blackboard):
   if event != null:
      # handle latest input event here. Keep in mind that once it is handled, set it to `null`

The above is not optimal, as it can cause some problems with when some other node handles the event instead. Alternatively, you could also have a separate InputHandler in your scene that has the Blackboard as a dependency. This one then could set flags on the blackboard depending on certain inputs, and your actions then can access the blackboard.
