Resolved Calling a method on a singleton? Equivalent in visual scripting

Hi,

I am learning visual scripting. I used to create singletons in C# and call some of their public methods from other classes.

I can't find an equivalent in visual scripting. Passing information from a script to another seems to be reliant on events only. It doesn't seem to be a bad thing, but before I create too many of these events I'd like to be sure I am not missing out on something.

Thanks in advance.

 

Yea, communication between graphs right now is entirely event based via Custom Events which need a target GameObject. No global events are currently available by default.

One solution is to target both the trigger and the receiver of a Custom Event to the same GameObject which serves as sort of central event distributor GameObject.

If that does not work for you. You can try Bolt Community Addons Defined Events which do have a global broadcasting variant. Those need a lil bit of C# scripting, however. Tutorial/docs for them are here: https://github.com/RealityStop/Bolt.Addons.Community/releases/tag/2.4

Bolt Addons also have UnityVS compatible branches.

 

Thanks a lot PanthenEye. It's great to know how visual scripting supposed to be used.

And thanks a bunch for the link. The targeted defined events will probably help me out.

Cheers!

 

Personally, in a previous project that used Bolt (now called UnityVS) I mixed and matched graphs with C# by calling methods from C# singletons in those graphs.

In Project Settings/Visual Scripting you can expose C# script public members to UnityVS via reflection. UnityVS then automatically generates reflected nodes for your public C# script variables, properties and methods as long as they're public. Any graph then can access a C# singleton instance from anywhere.

 

Oh that's great! That sounds like a really good way to mix and get the best of both worlds.

Thanks again for the tip.

 

Great! Looks like scripts in the global assembly (where MonoBehaviours are added by default in the project) are automatically parsed, no need to add them to the list of Type Options!

I just had to click Regenerate Units (since I've added methods since enabling Visual Scripting and generating UnitOptions.db for the first time), and the latest properties and methods appeared!

So I used the nodes: MySingleton - Get Instance > MySingleton - MyMethod and it worked.

 

Sorry for the late bump. I just wanna share my solution and maybe it'd help other late-comers.

I'm used to write a helper class derived from ScriptableObject.
It should be serving as a hub of public interfaces.
You create an instance of this type as asset, then you can call any of its public methods from any event slot, whether in-scene or off-scene.
