Visual programming conditional actions through editor

Hi, I would like to be able to do some extra visual programming in Unity editor, somet$$anonymous$$ng like t$$anonymous$$s:

Generally, I'd like to be able to check value of any property of any object and compare it to any other value, like value of property of some other object or I could just enter, lets say, int value manually. And if condition is met then do some stuff.

Specific use case would be, I want to attach t$$anonymous$$s script to my "UnitBuildScreen" canvas, and each time when enabling t$$anonymous$$s canvas I want to check if UnitBuilding object's Tier property is equal to 2, and if true then I want to enable part of my canvas where I can build tier 2 units.

I'd like t$$anonymous$$s conditions to be as generic as possible allowing for various types of comparisons and resulting actions at various points in time (on enable, on destroy, on user defined event...)

Question:
Does anybody know some existing solutions for somet$$anonymous$$ng like t$$anonymous$$s?
