Removing first entry when next enters

vanoevelenstef · January 8, 2020, 5:30pm

I’ve this code that lets you type words when keypressed but it only shows one word at the time. I want it to show multiply words (lets say 20) at the time and when word 21 is entered, the first word gets deleted and word 21 becomes 20, and so on and on.

Could somebody help me please? I don’t want to change the way I’ve coded the keys since I need it this way. Thanks in advance! Below is my code!

PFont font;

String myText = "Testing part"; // Starting Text, is only vissable once pressed

String aKPInput = "Medium"; // Input Key : A
String bKPInput = "Is"; // Input Key : B
String cKPInput = "The"; // Input Key : C
String dKPInput = "Message"; // Input Key : D
String eKPInput = "Conversation"; // Input Key : E
String fKPInput = "On"; // Input Key : F
String gKPInput = "We"; // Input Key : G
String hKPInput = "Contact"; // Input Key : H
String iKPInput = "Greenlight"; // Input Key : I
String jKPInput = "Processing"; // Input Key : J
String kKPInput = "Fake News"; // Input Key : K

String wKPInput = "And"; // Input Key : W
String xKPInput = "I"; // Input Key : X

You can add myText to an arraylist.

When it reaches 20 (size()) for loop over it with i < size()-2 (!!!)

a1.set(i) = a1.get(i+1);

vanoevelenstef · January 8, 2020, 7:43pm

I never worked with an arraylist before. Could you suggest code please?

Chrisir · January 8, 2020, 7:53pm

See reference for Arraylist

You can also use array

vanoevelenstef · January 8, 2020, 8:17pm

yeah sorry man. Realy sorry but I don’t understand anything of what you mean. I’m reading and watching videos about arraylists and how they work but can’t figure it out what you mean by (size)) and a1.set(i) …

It’s stupid to place my wrong codes that I’ve tried but honestly, I don’t understand it and I can’t figure it out.

If you feel like Arraylist is a bit overwhelming, it might be easier to start with arrays instead. Once you get the hang of that you could take another look at Arraylist, because it might be better suited for your situation.

You could see an array as a variable that holds multiple variable values. If we look at the first example on the page I linked just now, it’s similar to:

int number1 = 90;
int number2 = 150;
int number3 = 30;
int a = number1 + number2;
int b = number2 + number3;

In your case you have value for each letter in the alphabet, meaning you need an array size of 26 slots. You could appoint the value of letter a to the first slot, the value of b to the second slot, etcetera, until all the slots in your array are filled.

Using arrays can be handy for many situations. Aside from keeping your data (in your case the words Medium, Is, The, etcetera) compact together, it simplifies certain activities for you. For instance, you can check the length of your array:

int[] numbers = new int[3];
numbers[0] = 90;
numbers[1] = 150;
numbers[2] = 30;
println(numbers.length);

If you would have three separate int variables instead of an array, this functionality wouldn’t be available to you.

Hope that helps you on your way!

edit
Woops, studying @Chrisir his code and I made a mistake about the array size you need. Still hope this post is helpful in some way

Thanks man. Wouldn’t have don’t it without you. Thanks man!

I tried to implement the changes you send my in pm:
Atm it only speaks one word at the time, but not the complete array. It also doesn’t have a delay yet.

This is the code so far:

      text(wordsDisplay[i], 
        44, 44+i*19);

Did you do a research whether we can ask tts if it’s still speaking?

Chrisir · January 9, 2020, 7:02pm

this above version speaks the word as soon as it is entered

do you want this?

Or do you want the entire list to be spoken on and on?

vanoevelenstef · January 9, 2020, 7:16pm

The entire list to be spoken on and on. And when entering a new word, pause for a second to start looping again so this way the system couldn’t be overrun.

So when no key has been pressed for 3 seconds, then start entire list to be spoken on and on again. Is that possible?

Chrisir · January 9, 2020, 7:37pm

Possible

I don’t have time

but for speaking the list try

in draw

 // speak new word 
  tts.speak( wordsDisplay[i_speak] );
  println("Word " 
  +  wordsDisplay[i_speak]
  + " is being spoken");

if(!tts.isSpeaking())
    i_speak++;

and before setup()

int i_speak=0;

vanoevelenstef · January 9, 2020, 7:46pm

isSpeaking doesn’t exist so this don’t work :s

Chrisir · January 9, 2020, 8:03pm

do research please, if there is another possibility

otherwise, just do a timer and if it’s applies:

    i_speak++;

Chrisir · January 10, 2020, 8:56pm

see here

https://www.local-guru.net/blog/pages/ttslib

I haven’t found something like isStillSpeaking()

I think though, it’s queuing the text automatically internally.

So texts spoken won’t overlap

vanoevelenstef · January 13, 2020, 8:11am

I haven’t figured it out how to speak the how list at once over and over again. I don’t get the I_speak++; like you suggested implemented in the code :s Any suggestions still left?

kll · January 13, 2020, 9:16am

how about a restart timer with some estimated settings

import guru.ttslib.*;
StereoAudioPlayer sound; // unused interface

String[] words = {"Hi!","I","am","a","speaking","Processing","sketch"};
TTS tts = new TTS();

long ts,tm; //______________________ repeat timer

void setup() {
  tts.setPitch( 350 );
  tts.setPitchRange( 50 );
  tts.setPitchShift( 0.5 );
  tm = words.length * 500+2000; //__ 2 words per sec + delay ??
