How to evaluate distance in BT?

[AdamRParticipant]

I’m probably being thick here but is there a simple way to create a distance check in a constraint node?

Do I have to enter the equation for the distance between two points as the expression to evaluate? This seems a bit harsh.

I could create an action that does this, but then I can’t really use it for control flow of actions unless its put in a sequencer, but this also seems not ideal.

Is the correct way to create a highly specific subclass of the constraint?

You can write your distance constraint by inheriting RAINDecision.
_children is all child nodes of decision node, and you can do everything now.

Call node.RUN() can play the node.
Note that you need care playing order of RUNNING state node under your decision node.
