How to run a script in background and check for a state

Sometimes you want to do something advanced with Soundflow that our triggers don't support yet.
For example waiting on a specific window to become available, or something else.
In those cases you'll want to run a command in "background" mode, that is a command that's running indefinitely while allowing other commands to run (ie. don't block with a blue icon).

Here's some sample code to get you started with that:

//How often to check in milliseconds
var pollingIntervalMs = 100;

//sf.engine.runInBackground means: Run in background so other commands may run while we're running
sf.engine.runInBackground(function () {

    //while(true) is an endless loop
    while (true) {
  
        //Check if anyone requested us to cancel all running commands every time we enter the loop
        //The action will take care of aborting this command if necessary
        sf.engine.checkForCancellation();

        //Here you insert your code you want to execute every 100ms (or whatever you set the pollingIntervalMs to)

        //Done with this iteration of the loop.
        //To not eat up all the CPU, insert a 'wait' here so we wait until next time we want to check
        sf.wait({
            intervalMs: pollingIntervalMs,
            executionMode: 'Background'
        });
    }

});
