Can you call a Custom Action from a script?

Can you call a Custom Action from a script? If so, how? It doesn't seem like it's covered in the documentation.

It's not currently supported. Further, as the concept of custom actions relates closely to picking in the event system, and since picking is not a concept that is built-in to JavaScript, it's not necessarily obvious how to design a script interface for calling a custom action. They operate in different paradigms.

Thanks, that makes sense.

Custom actions aren't called per-instance in the event system though - an API that matches the way the event system actually works would look more like runtime.objects.Sprite.customActions.MyAction(arrayOfPickedInstances, ...params), but that's not a very natural for a JavaScript API, which is what I meant by the different paradigms.

Yes I understand but at the same time, stuff like conditions and actions are SOL-based in Eventsheet while their equivalent in JS interfaces are instance-based.

It would be better if Custom Actions scripting interface followed the same logic. SOL-based in eventsheet but instance-based in JS.
