Hello,
I am reading serial input from an Arduino to trigger matinee events in my level blueprint. i also want to have a HUD widget that gives visual info on the serial input…I really need to use the same variables to get the same readings as I want certain things to pause during Matinee events, etc. I am very confused about casting and sharing variables from blueprint to blueprint. What is the difference between casting and checking the little eye icon to make something global? I read the documentation on casting but I still really don’t understand it…it seems more like something you do to call up a variable instead of cast it out to other BPs…
From what I can tell…I can’t really use any variables from my level blueprint anywhere else…why would this be? Or (I hope) I am very wrong about this…seems like it should be a super simple thing to do which is making this all the more frustrating…I just want to use that newNum variable in a widget…what is that minimal target reference error? How can I get a minimal target reference? Any help on how I could make that happen would be very much appreciated!
