Hey Nick!

In the Event Graph of your Animation Blueprint make a Cast To node from the Event Blueprint Update Animation and Try Get Pawn Owner nodes. (Drag out the “Exec” pin, start typing “cast to” and find the node with the name of your Character Blueprint.)

Drag out the “As …” pin from the lower right corner of your Cast To node and search for the boolean variable you defined in your Character Blueprint.

Drag out the output pin and select “Promote to variable”. (Give a unique name to the New Variable if you wish.)

You can make references to this (latter) variable in your Animation BP.

Hope this helps!

Best Regards,
