Can't take references inside Level Blueprint

I tried to let a matinee play just when some boolean (inside an actor blueprint) are true… i tried to create a reference of that blueprint inside the “Level Blueprint” to get the booleans i needed but it gives me lots of error (accessed none from the blueprint reference)

This is what i tried to do inside the Level Blueprint:

The things selected are the one that give me the errors.

Blueprint is not actor it self it’s a class which let you create object of class. Just making variable of actor won’t work, it empty varable, that why you getting “None” errors, you need to get actor and set that actor in that variable. If this is actor that player controls and it possesed by PlayerController, you can use Get Player Character or Get Player Pawn, if not you will need to find other way, most easiest but more expensive way (which i think you should not use with “Tick” event) is using “Get All Actors of Class” node, which let you get all actors of specific class spawned in the world.

Since you seem to not understand basics of objects and classes, here my video about it:

Could you explain me an easy way to let a matinee start when i enter inside a triggerbox?
