how do you make a player input to change roll of the character

how do you make a player input to change roll of the character?

im confused on what you mean?

do you mean how to make a button press change the rotation, or the class (like tank to archer)?

You can add an input axis value, and then from input’s exec, do Add Controller Roll Input, use the input’s Axis Value return node as the Val input.

i did that the roll won’t change
