AudioKit OscillatorBank Instruments? - audiokit

I'm using AudioKit(which is awesome) and having a challenge finding a best practice for building a bunch of "instruments" can be triggered from the 3d controls in my app.
When I use
var oscillator = AKOscillatorBank()
as the base for sounds I can trigger individual notes on with
oscillator.play(noteNumber: ...)
and off with
oscillator.stop(noteNumber: ...)
Now I can have multiple tones playing within one instrument.
I then found the "string" and other classes in the Playgrounds such as,
var pluckedString = AKPluckedString()
which are awesome tonally but they are not Midi instruments, so they don't come with the handy .stop(noteNumber:) method, so while I can start multiple notes on the string, I can't stop them.
Is the solution to build my own "instrument" with an array of multiple AKPluckedStrings(), or is there something else built in accomplishing something similar already that I'm not finding?
Thanks in advance for any insights.

Yeah, you could follow the oscillator bank model to make a bank of plucked strings. I believe AKMandolin is set up like this too, for another example.

(Roblox scripting) help needed for "GetMaterialColor" or "SetMaterialColor"

I am new to roblox scripting, and I am working on a game. I am trying to make an exploration game with multiple planets. I want the colors on the surfaces of the planets to vary, but I also wish to use smooth terrain, as it is easier to use and looks nice. from reading a bit online, i have figured out i need to use "GetMaterialColor" or "SetMaterialColor". however, "SetMaterialColor", the one i needed specifically, requires two bits of information- the material and the color.
The issue comes from the "Material" part of this, as I have no idea how to make the script recognize what material I want to change. i tried multiple things, including but not limited to:
(grass, #,#,#)
(grass) (#,#,#)
("Grass"), (#,#,#)
("Grass", #,#,#)
or even just (#,#,#), without trying to get a specific material at all
so yeah, I need some help
here is the code:
local function onTouch(hit)
game.Workspace.Terrain:SetMaterialColor
end
script.Parent.Touched:connect(onTouch)
(there should be stuff after SetMaterialColor, that is what i need help with)
If you read the documentation on Terrain:SetMaterialColor(), you'll see that the first argument is a Material type, which is an Enum. So the method expects an Enum (or number to be more accurate), not a string denoting the material.
At the same time the second argument is a Color3, so (#,#,#) isn't apt, using it with the constructor Color3.fromRGB(#,#,#) is. If you are ever confused about what a method returns or expects, try referring to its documentation on https://developer.roblox.com/.
Here's an example of correct usage:
workspace.Terrain:SetMaterialColor(Enum.Material.Grass, Color3.fromRGB(123,123,123))
And ofcourse, Event:Connect() instead of Event:connect()

Lua NodeMCU cron | list all crontables

I just want to know how to find/create a function to list all crontables already scheduled in NodeMCU.
(http://nodemcu.readthedocs.io/en/dev/en/modules/cron/)
Thanks.
That feature is currently not available. There's a discussion about that at https://github.com/nodemcu/nodemcu-firmware/issues/1751.

Hi there.
So, there is some issues with it.
Now, schedule string description (like 0 1 * * *) is being parsed once you call :schedule method, and stored in packed bitmask format. There is difficult thing to process it back to string.
So list of entries without something that describing them is totally unusable (correct me if I wrong).
As module initiator and maintainer I prefer to keep it simple as possible, but if we can make it better - this is good :)

iOS Custom Keyboard, Suggestions from txt file

I'm making a custom keyboard for lawyers, and trying to load law related words in suggestion/prediction bar on top the keyboard based on what user types. Just like in stock keyboard. I have searched around but did not find any concrete answer.
I want to display suggestions of law related terms that I have in a txt file, all words are sorted alphabetically.
DEMO
Here is what I have tried:
UILexicon
let myLexicon = NSMutableDictionary()
self.requestSupplementaryLexiconWithCompletion { (theLexicon: UILexicon!) -> Void in
let lexiconEntries = theLexicon.entries
// Completion handler
for item in lexiconEntries {
self.myLexicon.setObject(item.documentText, forKey: item.userInput)
}
}
This code just gives 23 nil objects.
UITextChecker This is an iOS class that is designed to spot spelling errors, which makes it perfect for knowing if a given word is real or not. This is seems to be mainly for autocorrection, not for suggestion. Correct me if I'm wrong please.
I cannot somehow make sense out of these two classes.
How do I tell custom keyboard, "Hey if user enters "V" show the top 3 words that start from V, then if user enter a, fill the suggestion bar with words that start with "Va" and so on.
EDIT: Looks like someone ran into same problem. Here is a quote how they solved it, I will update with code once I finish figuring this out myself.
However, this was far from the truth - in fact, Apple do not allow access to their dictionary full stop, only offering a UILexicon class instead as stated in their docs:
Make use of this class, along with a lexicon of your own design, to provide suggestions and autocorrections as users are entering text.
As it turns out, the UILexicon class only really contains contact names along with any shortcuts (like the default On My Way!) defined on the device. So before writing the logic for a keyboard, you first have to implement your own autocorrect library.
We browsed through a few external projects to see if we could include them in the keyboard - most notably Hunspell, which is used by OpenOffice, and Presage, an intelligent predictive text library.
I spent a long time integrating the C++ libraries with the code, but in the end, in order to keep complexity down, we opted to use a combination of UITextChecker (which provides some basic corrections) and our own custom dictionary, containing a few commonly mispelled words.

Thanks!
You have to implement your own autocorrection system. UILexicon will only give you shortcuts the user has set up, words that they have added to the iOS Dictionary, and names of contacts. It has no awareness of any words that you yourself provide, whether in a txt file or in any other form.
If you want to use the TOMSSuggestionBar, it appears from the sample code that the onus is on you to convert your txt file into a core data model, and indicate to the suggestion bar how it is to interpret the contents of that model. You may also want to implement the data source protocol to get more fine grained control over the suggestions.
Autocorrection and next word prediction are not solved problems; I suggest you do your own research and find the solution that is best suited to your goals.

Merge Text/Fields

One feature/need for my application is that I have an audit trail for certain tables. This is something that I have done many times in the past using different languages. So far I have been able to come up with the idea of using an Observer to monitor changes to the model/table. This works exactly as expected. The issue I am having is with string manipulation/querying specific data.
I have a string such as this {{user.created_by}} changed {{user.id}}'s First Name from {{user.first_name_was}} to {{user.first_name}}
The main issue I am trying to solve is what would be the best way to convert a string to an object/attribute definition?

How do you make a combo of two emotes in lua in World of Warcraft work?

How do you make a combo of two emotes in lua in World of Warcraft work?
function Button2_OnClick()
PlaySoundFile("Interface\\Addons\\Fart\\common_fart[1].wav");
DoEmote("moon");
DoEmote("sit");
DoEmote("dance");
DoEmote("beckon");
end
I am using Wow Addon Studio to make a fart application on Wow.
I used this function, and only the sit motion showed, and beckon and moon only showed on the chat window. The dance emote didn't show up anywhere.
Blizzard has explicitly prohibited anything that can be used to make lua wait or pause because it is an essential ingredient to making a gold mining or grinding bot.
There isn't a native (i.e. lua only) way to have lua wait without using all the CPU. Outside of the WOW client, you'd use win.sleep or some other 3rd party API call that calls into the host application or operating systems threading functions.
It may be possible to simulate a wait by having code execute on a frequent event (such as text arriving at the chat window) and then in the event handler checking to see if enough time has passed to permit executing the next command in the sequence. This probably wouldn't be a very accurate timer and it would be rather complex as you'd have to create a data structure to hold the sequence of commands, the timings between each, the current command, etc. and so on.
This may be an intentional limitation of the API to prevent in game automation (botting).
What has worked for me is to have a global variable that is incremented through the loop. Such as
Integer count = 0;
function Button2_OnClick()
i++
switch
case(1)
PlaySoundFile("Interface\\Addons\\Fart\\common_fart[1].wav");
case(2)
DoEmote("moon");
case(3)
DoEmote("sit");
case(4)
DoEmote("dance");
case(5)
DoEmote("beckon");
default
i=0;
end
end
What you would have to do then is to click the button multiple times, but you would get the effect you're going for.
I would suggest you wait some time before doing the next emote. As far as I know, the server disconnects you if you spam too much. This might just trigger it sometimes.
Besides that, I guess maybe the client has a way of preventing it? In either case, I would suggest you add some sort of fraction-of-a-second delay between the emotes.
Cheers,
Amit Ron
Could it be that the last two can't be done while sitting?
infact, integer i = 0, because defining integer 'count' and then using i is incorrect. :)
