Hi everybody !

I got a problem with a line ramp, I try to make a ramp with variable values by using the $ sign, but I always got for $1 and $2: "argument number out of range".

here is a screenshot of it:

I looked in the help patch about dollar sign but I didn't find answer about that.
does somebody know what's wrong with it ?

You don't show how the [$1 $2( message is triggered, but what i guess you should do is this :

[trigger for the message]
|
| [first value for the pack]
| |
[f ] [second value for the pack]
| |
[pack f f]
|
[$1 $2(
|
[line~]

You could connect the [first value for the pack] directly to the pack, but then the message is also immediately sent to the [line~], which might not be what you want. Anyway, no need to struggle with a [set ( message to create another one.

You get the argument out of range because you are sending a bang to the dollar message and pd does not know how to interpret a bang for $ replacement.

thanks dude for the response, but it still don't work, it's really weird, the message is triggered by a bang from a metro (around 500) and the 2 floats came from webcam video analysis (that's why they are always varying and why i need "$" to create a ramp with there value, $1 is varying between 0 and 1, and $2 between 300 and 1000)
but what does it mean exactly in this case "argument number out of range" ?

ah ok !

so I can't bang over a [$1 $2( message for example. Thanks dude, I learn something important today
now it works, but how do I do If I want to create a ramp like this [$1, $2 $3( and bang it ? (because I need to unpack $1 $2 and $3 in order to bang them, but by unpacking, The comer disappear)
more clearly if I do :

[pack f f f]
|
|
[set $1 $2 $3(
|
|
[$1, $2 $3(

the comer between $1 and $2 disappeared when values are displayed (so it can't be used by a line for example) (I know that the set message isn't useful but i use it to display values in the message under it)

I don't really understand why you need to unpack them to send them to the [line~]? Normally the same approach can be used as above but then with [pack f f f]. Anyhow, to make it work you need to make sure a list of numbers arrives at the $ message.

if you send a list with less than 3 atoms to "$1 $2 $3", you get "argument out of range", because it doesn't know what to fill the missing $n with.

to add a comma to a message box, look at the "addcomma" message, should be in the help patch somewhere, maybe.

thanks claudiusmaximus , I Found [addcomma( with an example, it's really useful !
