actor moving back and forth problem

zombots

i have an actor that moves back and forth, that works fine, but i want it roll. how can i get that to happen?
i tryed using rotate but i only seems to work one way, it doesnt change wen moving the other way
this is my rule, is there a better way to do it that will make my actor roll? http://d.pr/3ohh

any help would be really appreciated

thanks

you could do when self motion linear x is > 0 rotate clockwise, then have when self motion linear x <0 rotate counterclockwise

i have done that but it wouldn't work.
now i have added rule to +1 or -1 from linear x.
now counterclockwise works but not clockwise, just slides

ok i got it working, just added the counterclockwise to otherwise and now it work
