I knew Hermann would solve this.

One may use [*] return defaultSetting + c*f(n, 5*tData/maxvalue) if the slider range is from -maxvalue to maxvalue. the constant factor c will depend on tData (you use 60 in your example) -- n is any real > 1 (try n=3/2 or n=2 or n=5/2 or n=3 or n=4) -- (n doesn't need to be an integer, essential is to set n>1). -- x is any real, here between -5 and 5 -- I would try to use -3 to 3 (--> the 3 replacing 5 in [*]) function f n,x return x*abs(x^(n-1)) end f Kay, I write this in order to remark that instead of the two cases -x*x, if x<0 x*x, if x>0 one could write x*abs(x) which has the correct sign [because abs(x) = -x if x<=0 and abs(x) = x if x>0] p.s. the thumbpos is since LC 7 a real, rounding is for setting the thumpos not necessary any more. One should know that if one needs an integer when getting the thumbpos. ======= Hermann _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
