How can I transfer the velocity values from Character to the Pawn with trigger Box. When the character overlaps with the box collision. There are several pawns.
transfer the velocity values
What does this mean?
What is supposed to happen once the Pawn learns the velocity of the entering character?
What you’re saying is just this:
But I’m almost certain you’ll need something more / or something else.
When the character leaves the Box
Trigger, the value transfer must stop.
Enigmatic 
Strange, but OK. Would be easier to suggest a solution if we knew what you were actually making…
transfer the velocity values from
Character to the Pawn with trigger
Box. When the character overlaps with
the box collision.
So you want the Pawn to know the Character’s velocity for as long as they’re overlapping the pawn’s component:
This might be completely wrong as I don’t understand what’s the purpose. Or there might be a much better, logical, practical or efficient way of doing what is really needed… Meh.
Good luck.
When the character leaves the Box Trigger, the value transfer must stop, then the value in Pawn should be 0.
