The helpfile that comes with the line object describes various ways you can linearly move between two numbers, it explains how to use variable time values, but it doesn't explain variable destination values, can anyone help me with this?

for example a volume fader on an interface, the destination values are constantly going to change as the user wants to change things.

using-line-with-variables

this was a bit of a dumb question, it wasn't as difficult as i expected, I've just created a line object with no additional arguments, time value goes into the middle inlet and a variable destination value can go into the left inlet

You could also [pack] your variables into destination-time pairs. This way the time setting is remembered and doesn't have to be set again each time you change the destination value.

in between your number and the line object, use a message box saying $1 5

$1 is a variable - it'll be replaced with any number the message box recieves. 5 means 5 milliseconds. connect the message box to the first inlet of line (or line~) and it'll fade to any value you send to the message box over 5ms. obviously write $1 20 or whatever if you want a longer fade time.

$1 is a variable - it'll be replaced with any number the message box recieves. 5 means 5 milliseconds. connect the message box to the first inlet of line (or line~) and it'll fade to any value you send to the message box over 5ms. obviously write $1 20 or whatever if you want a longer fade time.
simple!

I'm pretty sure line doesn't like this, I found a really easy way to do it eventually;

slider (or rotary/int etc) goes into the first inlet of line, and also goes into a bang message, the bang message then goes into a message box with your desired time value

every time you move the slider you trigger the bang message and the output of line will linearly travel to your new destination value :)

thanks for your help guys... I would like to understand pack a bit more can anyone point me to a good source or otherwise?

sorry to be more specific, line doesn't seem to like $1 variables, I might be wrong!

it might be easier to see what's happening if you change the message 

this way line will ramp to the new variable over 2 seconds, instead of
