Simple question how to cast to another BP from a level BP

well this did not turn out so simple
Over all overview

  • This game is a Sidescroller

  • As you run it loads levels ahead of you and unloads behind you

  • It uses the Level Blueprint in order to do that

  • The Thing is I want to access the variable that has the speed rate so as you go on the speed increases

  • but I can’t access it because it does not exist at the moment

  • and I tried doing that but it only did it on that Individual one

  • So What’s needed is to change the original actor’s property so that the instances will inherit from that original actor
