Found issues

• Variable & event names are identified by literal string (for variables user needs to type it manually or sometimes the dropdown will work)

• Variable & event names cannot be edited across all instances (must be edited by hand)

• Events cannot return params and input count must be manually added

• Most inputs of nodes cannot be directly typed in, this means you need to add another node for the literal value

• Wildcard pins type are not updated after connecting a known type

• A error can be reported from a nested call

  • Example :
    • Something calls EventA, EventA calls EventB
    • an error occurs in EventB
    • In the console the error can be reported at EventA, with not indication in the call chain

• Adding object variables to prefab is broken

  • If you add a object variable to the prefab definition, already placed instances will not be updated (resulting in missing object variables)
  • same issue with default value

• Broken node search:

  • No contextual search
  • If dragging from pin, can hide possible nodes (I recommended always searching from nothing, in some simple cases like with bools, ints, floats or flow control it works)

• Weird parallelism for execution (its all events, not functions, so Unity doesn’t wait for your code to finish before going to the next execution)

  • I saw a checked value becoming false after a check IN THE SAME execution flow (in one case for now)
    • Details:
      • OnUpdate:
        • Check if MyVar is true, if true:
          • Do stuff
          • Do more stuff <⇐ ERROR ! MyVar was now false (like if it was updated in a parallel process)
    • Solution: Each time i needed to do something that required MyVar to be true, i checked it before
  • In another case a game object returned from a collision event was becoming null after a single node execution (caching it fixed the issue)

• Nested graphs cannot have multiple output triggers (But its allowed to create multiple ones ?)

• Returned values from nodes aren’t cached, meaning you need to save it or it will rerun it, or error (dynamic access error)

• No delegates support

• Cursed and time consuming to make callable nodes from C# for graphs

• Cannot diff properly

• And of course, bad UX
