Hi,

I'm using he keyboard to control a robot in Pd, but i dont get how to use the keyname object.

I implemented this:

[keyup] [key]
| |
[0 ( [number\
| /
[route 119 100 115 97]
| | | | |
[up] [rigth] [back][stop]
It worked just fine whit the WASD control. But when i try to use the arrows to control it does not work, for the arrows i implemented this:
[keyup] [keyname]
| |
[0 ( [symbol\
| /
[route Up Down Rigth Left]
| | | | |
[up] [rigth] [left] [back][stop]
BUt aparently the route is failing whit symbols, i'm, probably, using route in the wrong way, how should i do to route symbols?
Thanks![/left]

Hi,

Route can be used to route pairs of data to specific places.

From [keyname] you get two pieces of information. The key label and a up/down action, e.g:

Up 0
Up 1

If you think about the first value being the receiver name and the second being the variable you want to pass with it. The [route] object will the output the variable associated with a receiver that matches its arguments. [route] will also strip off the receiver name so that you would be just left with the variable.

[keyname]
| \

// create a list from keyname e.g. 'Up 1'
|
// route doesn't like lists so we strip off the list prefix
|
[route Up] // looks for a message with 'Up' in it and pass the next value to its outlet
|
[sel 1]
