Re: [expr ] help needed

Thank you Antoine for help!It works, but only once. If I feed the results from [expr] into [v x] and [v y], it starts to act like in my original post. Maybe I completely missed the purpose of [value] object. My idea was to set only the initial values and then advance with 90 degrees of rotation from updated x and y values with every bang the [expr] object receives.

 works with [value]s too:

could it be some confusion between x, y from [value x]. [value y] and 
the x and y used for input/last output (e.g. in fexpr~)?

does it work if you rename x, y to a, b?
