How does builder.connectToScript() work?

[Orvillain]

I have this code:

inline function build_midi_script_processors()
{
	for (i = 0; i < max_count; i++)
	{
		local script_processor = builder.create(
		builder.MidiProcessors.ScriptProcessor, "script_processor_" + i,  i+1, builder.ChainIndexes.Midi);
		
                builder.connectToScript(script_processor, "{PROJECT_FOLDER}/Scripts/ScriptProcessors/ghostalpha2/sampler_scriptprocessor_template.js");
		
	}
}

But I get this in response:

script_processor_0:! onControl could not be parsed!
script_processor_1:! onControl could not be parsed!
script_processor_2:! onControl could not be parsed!
script_processor_3:! onControl could not be parsed!
script_processor_4:! onControl could not be parsed!
script_processor_5:! onControl could not be parsed!
script_processor_6:! onControl could not be parsed!
script_processor_7:! onControl could not be parsed!
script_processor_8:! onControl could not be parsed!
script_processor_9:! onControl could not be parsed!
script_processor_10:! onControl could not be parsed!
script_processor_11:! onControl could not be parsed!
script_processor_12:! onControl could not be parsed!
script_processor_13:! onControl could not be parsed!
script_processor_14:! onControl could not be parsed!
script_processor_15:! onControl could not be parsed!

I've tried all manner of different paths to the script, and nothing seems to be working.

The script template itself is:

 function onNoteOn()
{
	Console.print('onNoteOn method');
}
 function onNoteOff()
{
	Console.print('onNoteOff method');
}
 function onController()
{
	Console.print('onController method');
}
 function onTimer()
{
	Console.print('onTimer method');
}
 function onControl(number, value)
{
	Console.print('onControl method');
}

@Christoph-Hart Could this be a bug? I followed the instructions on this page:
https://docs.hise.audio/scripting/scripting-api/builder/index.html#connecttoscript

Still finding issues with this. Anyone got a snippet that demonstrates connecting to a script via Builder.connectToScript ?

[Fergler]

Same issue. Perhaps related, this also is not working:

var test = builder.create(builder.MidiProcessors.ScriptProcessor, name, parent, builder.ChainIndexes.Midi)

builder.setAttributes(test, {"Bypassed": 0, “Script”: #script contents# } );

test becomes an object 0xEtc reference, but nothing can be set to it from setAttributes. I’m just wondering if both issues are related in a backend method.

This method used to work in one of the 3.x versions, sorry I can’t be of more detail

@Fergler yeah you can use this method with float attributes only.

The connectToScript function is almost correct, but the reference does need to use the Scripts folder in its path:

{PROJECT_FOLDER}ScriptProcessors/MyProcessor.js should work, however it‘s highly recommended to move the script out of this directory as it will be replaced on the next save.
