Interfaces doesn’t allow you to trigger events without passing the actor that have the interface in parameter. Or you can’t just delegate an event from a specific interface without having one reference attached.
I already made a World Sub System class, its really usefull. But in my case I would like to makes static function where I can bind event. Such as “Set Timer By Event” for exemple where you can delegate an event from this node. I would like to be able to do the same and if possible, bind event that takes specific parameter.
All of this in c++ of course I don’t think that blueprint is enough for this kind of advanced system.
Thanks for your response anyway, same for game_maker, thanks for trying to help me
