You can’t have a custom event inside a function. As I said:
And then cut / paste this node outside
of the function.
Place the event outside of this function. Cut and paste it from the Function to the Event Graph. Ctrl+X on the node and Ctrl+V in the graph.
In which blueprint (HexTiling/HexMesh)
I have to add event dispatcher?
In the Hex Mesh. But if you’re using just Click, you already have it:
Actors come with a lot dispatchers already, you can add your own to send custom data.
You can also create this event manually if you prefer, but adding signatures is a hassle.
