Hello,

 

I mixed up couple  sketches to learn more about tabs in controlP5. In this example I need to put text to second tab, but line 40 gives me an error. what wrong I am doing ?

thanks for help.

2. import controlP5.*;
3. 
   
4. ControlP5 cp5;
5. Textarea myTextarea;
6. 
   
7. void setup() {
8.   size(700, 400);
9.   cp5 = new ControlP5(this);
10. 
    
11. 
    
12.   cp5.addTab("extra")
13.     .setColorBackground(color(0, 160, 100))
14.       .setColorLabel(color(255))
15.         .setColorActive(color(255, 128, 0))
16.           ;
17.   cp5.getTab("default")
18.     .activateEvent(true)
19.       .setLabel("first tab")
20.         .setId(1)
21.           ;
22. 
    
23.   cp5.getTab("extra")
24.     .setLabel("Second tab")
25.       .activateEvent(true)
26.         .setId(2)
27.           ;
28.   myTextarea = cp5.addTextarea("text")
29.     .setPosition(100, 100)
30.       .setSize(200, 200)
31.         .setText("some text to show in second tab")
32.           ;
33.           
34.    cp5.getController("text").moveTo("second tab");// ERROR
35.          
36. }
37. void draw() {
38.   background(0);
39. }
40. 
    

I' have processing application which use serial port to communicate with arduino, it's works fine unless, I want to use it on another pc. I  found a problem,  that  different computers, have different numbers of com ports, and I  must specify a com port in my code, so I must to recompile processing application each time I change a computer. Maybe somebody know how automatically do that, without recompiling processing sketch each time ?

Thanks for help.

            Hello,

                  I want be able to control echo effect  with toggle controller, so  I created method echo and after that used controlEvent method, but none of these technique worked for me, I guess I need some kind of setter, but don't know which one, maybe somebody know how to turn off/on echo effect with toggle ?

                                                                                                                                        

                                                                                                                                                  thanks for help

      how to change this code that if I press radiobutton "A", code in 21-22 lines would be executed, if  I press "B" nothing happen,  if I press "C", code in  25'th line would be activated. I know it's noob question, but I am really new in programming.

     Hello,

            I am trying to make a virtual theremin with beads, to make it sound  like a  real deal  I applied tremolo effect like in code below, but if I try to change sound pitch quickly it begin generating an awful sound, you  clearly can hear that in example below, just try to move mouse cursor  fast as possible up an down. So my question is, what to do, to be able to change sound pitch quickly and smoothly and still get decent tremolo effect

                  thank in advance :)

Controlp5 have a lot great tutorials of how to put sliders, toggles etc. to separate tabs, but I  cant find any explanation of how to put basic shapes to different tabs.

in example below I want  put rectangle to  "rectangle" tab and ellipse to "ellipse" tab.

that is the  best way to do that ?

thanks for help.

2. import controlP5.*;
3. ControlP5 p5;
4. 
   
5. 
   
6. void setup() {
7.   size(400, 300);
8. 
   
9.   p5 = new ControlP5(this);
10.   p5. addTab("rectangle");
11.   p5. addTab("ellipse");
12. }
13. 
    
14. void draw() { 
15.   background(120);
16.   rect(30, 20, 55, 55);
17.   ellipse(150, 150, 100, 100);
18. }

Thanks for help.

Hello, 

I am trying get familiar with beads audio library. Now I applied echo effect to simple sine wave generator, but  after that volume control  does not work,  how to fix that problem ?

thanks for answer

how to create echo effect with Minim library? 

thanks in advance :)

I am curious which class have methods setup() and draw() in processing?

thanks :)

very simple question. How to measure code speed. Is there any   function  or library witch could help me?

Thanks :)

 Simply question. How to use volume control setter in Minim ?

Thanks in advance :)

onother beginers question.

What is way to make local variable to global, o simply visible to the other methods.

In this example I want to print variable c in method   ex_1, what is solution ? 

thanks in advice 

3. int a = 1;
4. void setup() 
5. {
6.   ex_1();
7.   ex_2();
8. }
9. 
   
10. void ex_1() {
11.   int b = 1;
12.   println(c);//error
13. }
14. void ex_2() {
15.  int  c = 2;
16.   println(c);
17. }
