Variables not declared? #1

Closed carltesta closed 5 years ago

carltesta commented 5 years ago

When I attempt to run this simplified code:

// uses argument as variables in hydra
freq = 10

msg.on('/test', (args) => {
 freq = args[0]
 console.log(args[0])
})

osc(() => freq)
.out()

from the osc.js example I get the following error:

Uncaught ReferenceError: freq is not defined

What am I missing?

And when I restart ATOM after a force quit I get the following error from the osc-loader:

osc-loader.js? [sm]:105 events.js:173
      throw er; // Unhandled 'error' event
      ^

@carltesta ctrl + enter runs a block of code (separated by line breaks) make sure you run the line with freq = 10 before running the rest of the code, or combine all of the code into a single block

Of course, so sorry for the simple mistake. I tried CTRL-SHIFT-ENTER to run the whole file, but I think I still got the same error because they weren't in a block. Thank you, I'm excited to try and interface Hydra with SuperCollider via OSC.
