How to get persistent level from the game blueprint?

I can use interfaces to pass variables per:

however, how would i call custom events? If I create a variable of the levelscriptActor type and cast to the persistentlevelscript, i can access the level event from the game blueprint with no problem, however, then I can’t save the blueprint because of an external reference.

any ideas?

this was actually answered in the forums. the solution was to use an event dispatcher which worked great.

Could you please refer us to some links that helped you find a solution with dispatchers? Forum or youtube links?
