why are you using family , do you want it to be done with family , or you want it to be done any way.
I am not sure, but might be due to family, Since i never used them so not sure, try to use all button individually as i also did it without family and for me working fine, i mean in my game.
you need to make two events for each button, that's touching and not touch and set the animation frame there, and i think that will work , if not let us know again.
like for Example :-
touching right button > set animation frame to 0 or 1
not touching right button > set animation frame to 0 or 1
same for all buttons you want to make.
Will try to help you if we can . That's C2 community.
Edited :- Did some spelling mistakes and added example.
