Method for detecting whether the samples were found

[aaronventure]

I'd like to roll my own overlay for not detecting any samples.

I can't find any way to do this in the API. Basically I want the same return bool that the internal method for checking the samples provides which then results in the built-in overlay for locating the samples popping up.

If I'm not just being blind and failing to see it, I'd kindly request that method be exposed to us. So a simple call that returns 0 if the samples for any of the sample maps weren't found at the given LinkOS path or if the LinkOS file doesn't exist.

I want the same thing. The error handler should be able to do this, but it's broken - https://forum.hise.audio/topic/7058/custom-error-messages/13

@d-healey I'm getting to this now, and have been able to get the error handler working for detecting samples.

const var errorHandler = Engine.createErrorHandler();
	
	errorHandler.setErrorCallback(function(state, message)
	{
		 ErrorHandler.errorLabel.set("text", errorHandler.getNumActiveErrors() + " " + errorHandler.getCurrentErrorLevel() + " " + state + " " + message);
		 
		if (state == 9) // if samples not detected
		{
			// show your own overlay here
		}
		 
	});

	inline function onlocateSamplesButtonControl(component, value)
	{
		if (canExecute.locateButton) // prevent execution on init
		{
			FileSystem.browseForDirectory(FileSystem.UserHome, function(result)
			{
				Settings.setSampleFolder(result);
				// remove overlay
				Engine.reloadAllSamples();
				
			});
		}
		else canExecute.locateButton = true;
	};
	
	Content.getComponent("locateSamplesButton").setControlCallback(onlocateSamplesButtonControl);

If the user pointed to the wrong folder, the error will trigger again after attempting to reload all samples.

@aaronventure oh cool, I'll check this out

[aaronventure]

@d-healey So it's 9 in case the link file isn't found, and 10 if it exists the samples are not found in the specified directory.

[aaronventure]

@aaronventure Found a better solution

	inline function onlocateSamplesButtonControl(component, value)
	{
		if (errorHandler.getCurrentErrorLevel() == 9 || errorHandler.getCurrentErrorLevel() == 10) // prevent execution on init
		{
			FileSystem.browseForDirectory(FileSystem.UserHome, function(result)
			{
				errorHandler.clearAllErrors();
				Settings.setSampleFolder(result);
				Engine.reloadAllSamples(); // this seems to be synchronous and freezes the entire script execution
				
				// the browse callback will execute in entirety before the error handler reevaluates the situation
				// so we delay enough for it to throw another error if the directory is wrong and prevent overlay removal
				Content.callAfterDelay(250, function() 
				{
					if (errorHandler.getCurrentErrorLevel() == -1)
					{
						// if samples found
					}
				}, {});
				
			});
		}
	};

Whilst we are here - I think it would be nice to have the partner of

Settings.setSampleFolder()

so

reg myString = Settings.getSampleFolder();

[d.healey]

@Lindon You can do that already. FileSystem.getFolder(FileSystem.Samples).toString(0);

@Lindon What's wrong with FileSystem.getFolder(FileSystem.Samples)?

Damnit David!!!

-- well whats wrong with it is that it just didnt occur to me.....;-) So ignore me..
