I’ve spent lots of time trying to figure out why my project works differently when being built.

And finally found that I was using “.isConnected” in the code and it returns false when the project is run not in editor.

Digging further found this:

#if UNITY_EDITOR

ValidateConnections();

#endif

Seems that this part causes the problem.

So, is it a bug or am I not supposed to use isConnected in the code?

Hello,

The isConnected property is not really supposed to be used in runtime code, but I could change the code so that it can be used.
What is your use case if I may ask?

Thanks!

Sorry, for the late reply. We’re having Orthodox Christmas holidays here in Russia 😉

I’m using it to return a specific value if the input is left not connected:

var par_wgo = AddValueInput<WorldGameObject>("WGO");

...

var obj = WGOParamOrSelf(par_wgo);

...

public WorldGameObject WGOParamOrSelf(ValueInput<WorldGameObject> param)

{

if (param.isConnected || !param.isDefaultValue) return param.value;

WorldGameObject res = wgo;

return res;

}

Or maybe that’s not the right way to do it?

PS: I can’t use comparation to null because, NodeCanvas puts “Self” in the input if it is not connected. Also, I don’t want to disable that “self” feature because I’m using it sometimes…

Hello again and happy new year!

Is that code part of a custom node?
If so, is the reason you are doing these checks, to avoid linking up variable nodes in the graph to avoid redundancy?
In either case, I can see that .isConnected can be useful in certain cases 🙂 As such I will fix this so that it work in runtime for the next version, but until that next version, you can indeed remove the #if UNITY_EDITOR define from “ValidateConnections” and as such have it work as it was working before.

Thank you!

Hi there!

Basically, I need to know if the input of the node is really empty. Even if it can be converted to GameObject and the nodecanvas code will auto-fill it with the “self” value. I don’t need that “auto-fill with self” feature in this particular case.

Hey!
Thanks for the follow up.
Got it! 🙂 I will make sure that .isConnected works as expected from the next version and on! 🙂
