Sample map Expansion Tutorial

[BWSounds]

@d-healey
ok, so far I have this, which loads the samplemaps into a combobox(list1)...

It works great, but the {EXP:..} text which is included with the samplemap text is a bit unappealing.

So what I want to do is remove it {EXP:..} , but im lost on how...

const var expHandler = Engine.createExpansionHandler();
const var expansions = expHandler.getExpansionList();
expHandler.setAllowedExpansionTypes([expHandler.FileBased, 
                                     expHandler.Intermediate, 
                                     expHandler.Encrypted]);
const var expansionNames = [];


for(e in expHandler.getExpansionList())
    expansionNames.push(e.getProperties().Name);


const   Sampler1 = Synth.getSampler("Sampler1");
 const list1 = Content.getComponent("list1");
 list1.setControlCallback(onlist1Control);
 const var namesExp = [];
 
 
inline function onlist1Control(component, value)
{
	if (value > 0)
	{
		local sampleMap = component.getItemText();
         


		if (sampleMap != "")
			Sampler1.loadSampleMap(sampleMap);	
		{	
			
			namesExp.clear();
		    var smname = expSampleMaps[value];
			
				
			for (e in smname)
		    e.replace("{EXP::" + getExpansionName() + "}", ""); 
		    list1.set("items", smname.join("\n"));
			
 
    }			
  }		
}


expHandler.setExpansionCallback(function(e)
{
	list1.set("items", e.getSampleMapList().join("\n"));
});

no iterable type keeps popping up, so I know im way off. Did a search on it but nothing came up.

@danh said in Sample map Expansion Tutorial:

for (i = 0; i < sampleMapsed.length; i++)
{
sampleMapsed[i] = sampleMapsed[i].replace("{EXP::");
sampleMapsed[i] = sampleMapsed[i].replace("}");
sampleMapsed[i] = sampleMapsed[i].replace(expName);

    }

humm.. I tried something like that but the sampler didn't recognize the samplemaps..
I look into it again

@bwsounds I excecute this in an expansionSelector callback - which in my case is a combobox. How are you selecting and switching between expansions? And do you have 'factory' presets as well?

If what you want is similar to mine I can send over my code when back at my machine tomorrow

[BWSounds]

@danh
That would be great!
And no factory presest, I was planning on having an expansion titled "FACTORY"
also Im using the preset browser to switch between expansions.

@bwsounds here it is, essentially it's all dealt with with the 'expHandler.setExpansionCallback' function. 'SAMPLEBOX' is my combo box which lists the available sample maps for the user to browse, and the 'sampleMapsed' array is the list of expansion sample maps (so I guess you can ignore the 'sampleMaps' array). It also removes all the Expansion text so you just get the name of your sample map in the combo box.

const var expHandler = Engine.createExpansionHandler();

const var expansions = expHandler.getExpansionList();

expHandler.setAllowedExpansionTypes([expHandler.FileBased, 
                                     expHandler.Intermediate, 
                                     expHandler.Encrypted]);
                                     
const var expansionNames = [];
/// Push 'FACTORY" into the available expansion packs list so users can navigate back to factory presets

expansionNames.push("FACTORY");

for(e in expHandler.getExpansionList())
    expansionNames.push(e.getProperties().Name);
    
const var ExpansionSelector = Content.getComponent("ExpansionSelector");
ExpansionSelector.set("items", expansionNames.join("\n"));

// Implement the expansion switch

inline function onExpansionSelectorControl(component, value)
{
	local expansionToLoad = component.getItemText();
	
	// We want the first item to reset the current expansion
	// so we need to change it to an empty string
	if(expansionToLoad == expansionNames[0])
        expansionToLoad = "";
    
	expHandler.setCurrentExpansion(expansionToLoad);
};

Content.getComponent("ExpansionSelector").setControlCallback(onExpansionSelectorControl);

var sampleMaps = Sampler.getSampleMapList();
var sampleMapsed = Sampler.getSampleMapList();

inline function newcombobox(newExpansion)
{

       if(isDefined(newExpansion))

    {
        local cx = expHandler.getCurrentExpansion();
        sampleMaps = cx.getSampleMapList();
        sampleMapsed = cx.getSampleMapList();
        local expansionProps = cx.getProperties();
        local expName = expansionProps.Name;

        for (i = 0; i < sampleMapsed.length; i++)
        {
        sampleMapsed[i] = sampleMapsed[i].replace("{EXP::");
        sampleMapsed[i] = sampleMapsed[i].replace("}");
        sampleMapsed[i] = sampleMapsed[i].replace(expName);

        }

        SAMPLEBOX.set("items", "");
        SAMPLEBOX.set("items", sampleMapsed.join("\n"));
       
    }
    else
    {
        sampleMaps = Sampler.getSampleMapList();
        SAMPLEBOX.set("items", "");
        SAMPLEBOX.set("items", mySampleMapNames.join("\n"));

    }

}

expHandler.setExpansionCallback(newcombobox);

newcombobox(undefined);

@danh
Thank you!
But im still having the same issue... when I do this

     //   sampleMapsed[i] = sampleMapsed[i].replace("{EXP::");
     //   sampleMapsed[i] = sampleMapsed[i].replace("}");
     //   sampleMapsed[i] = sampleMapsed[i].replace(expName);

the samplemaps load up, but if I remove the

//

the samplemaps load up.... i'll dig around and mess with this a bit, maybe im missing something... thank you.

[BWSounds]

@danh
ok, after a few days I figured it mostly out, thank you.
one issue still remains... once I switch back to "factory" my combobox doesn't populate those samplemaps... What could cause that?

@bwsounds I don't think the expansionCallback is triggered when you set the currentExpansion to "". You should test it to see if that is the case.

[BWSounds]

@d-healey
humm, still having the same issue.

[d.healey]

@bwsounds Need to see some code to know what you're doing. Does the expansion callback trigger?

[BWSounds]

@d-healey
I removed the "currentExpansion to" but The factory samplemaps still wont populate in the combobox after previously selecting an expansion.

const var expansions = expHandler.getExpansionList();

const var expansionNames = [];

   expansionNames.push(e.getProperties().Name);

   }

   }

	}

Does the expansion callback trigger when you deselect the expansion and return to the "factory" setup?

[DanH]

@bwsounds You're selecting expansions / factory etc through the preset browser, right?

[d.healey]

@danh He has a combobox

yep

@danh said in Sample map Expansion Tutorial:

originally yes, but i switched to a combobox as I thought it would help me with this issue.

[d.healey]

@bwsounds In your expansion callback you are checking if newExpansion is defined, when you revert to the factory setup newExpansion will be "" which is also defined, so you won't hit the else clause.

[BWSounds]

@d-healey
ahh makes since.
