I'm wondering why a ControlP5 slider always ends up on my main canvas when I need it to go on the special control window (which I never get to see).

Has anyone had this issue before? I'm wanting to have a control window setup which would have sliders to control graphics on the main canvas, but in a separate window.

Here's my code - thanks for any ideas people. (Still can't get this code to output right in these forums - ctrl & O not working again for some reason).

`import controlP5.*;

//Declare Controls ControlP5 controlP5; ControlWindow myControlWindow; //initialize control window Controller slider; //initialize slider

//Setup

void setup() { //Initalize Main Canvas size(1480, 360);

//Initialize ControlP5 and Control Window controlP5 = new ControlP5(this);

myControlWindow = controlP5.addControlWindow("Control Window", 200, 200, 480, 360);

//Initialize Controls slider = controlP5.addSlider("X", 0, 30, 15, 88, 70, 320, 24);

}

//Draw

void draw() {

}`

I'm trying to create a lineal drawing using the sound information from an audio sample or the computer internal mic. I did this script but I'm just getting a straight line. Any ideas?

thanks!

import ddf.minim.*;

Minim minim;
AudioInput in;

float x;
float y;
float px;
float py;
float vel;
float dir;

void setup(){
  size(400,400);
  stroke(0);
  background(255);
  smooth();
  frameRate(30);

  x=y=px=py=200;


  vel = random(5);
  dir = random(360);

  minim = new Minim(this);

  in = minim.getLineIn();
}

void draw(){
  px = x;
  py = y;

  x += cos(radians(dir)) * vel;
  y += sin(radians(dir)) * vel;

  stroke(0);
  line(px,py,x,y);

  float value = 0;

  for(int i = 0; i < in.bufferSize() - 1; i++) {
      value += in.mix.get(i);
  }
  value /= in.bufferSize();
  dir += random(-30, 30) * value ;
}

void stop() {
  minim.stop();
  super.stop();
}

hello guys.

I am trying to save the value of textbox in a variable, I created textbox with the help of "G4P GUI BUILDER", so how can I store the typed value in variable.

Hello friends, I am trying to control the code to display with checkbox, I have two function

void render() and display ()

which i call in event control and with if else statement I want to display this. but it is not show. and when i put it event handler function in run() function its give error that variables are not declared. could you please point our my mistake.

I created checkbox with G4P GUI Builder.

my code is here.

` // Create all the GUI controls. // autogenerated do not edit public void createGUI(){ G4P.messagesEnabled(false); G4P.setGlobalColorScheme(GCScheme.BLUE_SCHEME); G4P.setCursor(ARROW); surface.setTitle("Sketch Window"); chkBox = new GCheckbox(this, 4, 8, 123, 31); chkBox.setTextAlign(GAlign.LEFT, GAlign.MIDDLE); chkBox.setText("Display Nuclus ID"); chkBox.setTextBold(); chkBox.setOpaque(false); chkBox.addEventHandler(this, "chkNucleus"); }

// Variable declarations // autogenerated do not edit GCheckbox chkBox; //nucleus is the centre of the niche

class Nucleus {

int id; PVector pos; PVector nucleus = new PVector(); boolean frozen; /............................................................................................./ Nucleus(int identity, boolean hunger, PVector loc) { id = identity;

    pos = loc.get();

} /............................................................................................./

void run() { updatePos(); //render(); // display(); //chkNucleus(GCheckbox source, GEvent event);
}

void updatePos() { // println(id, "current pos", pos); nucleus = new PVector(); for (int i=0; i<space.length; i++) { if (space[i].ref == id) { for (int j=0; j<space[i].nodes.length; j++) { nucleus.add(space[i].nodes[j].pos);

    }
  }
}
nucleus.div(numNodes);

// println("current nucleus", nucleus); // float d = pos.dist(nucleus); // if (d == 0) { // frozen = true; // println("FROZEN .........!!!!!!!!!!!!!!!"); // } pos = nucleus; // println(id, "new pos", pos); }

public void chkNucleus(GCheckbox source, GEvent event) { //CODE:chkBox:929344: //println("chkBox - GCheckbox >> GEvent." + event + " @ " + millis()); //println(event);

if(chkBox.isSelected()){ println("ok"); display(); } else{ println("no"); render();

} }

void render() { stroke(200, 70); // stroke(250, 50); noFill(); ellipse(pos.x, pos.y, 8, 8); stroke(10); point(pos.x, pos.y); }

void display(){ // to display number. stroke(200, 70); // stroke(250, 50); noFill(); ellipse(pos.x, pos.y, 8, 8); stroke(10); point(pos.x, pos.y); fill(200, 155, 0); textAlign(CENTER, CENTER);

text(id, pos.x, pos.y);

Hi there,

As the title suggests I'm trying to only allow yaw and roll rotations, is that possible?

I'm aware of these functions but it only seems to be one or the other!?

// By default, the camera is in "free rotation" mode, but you can
// constrain it to any axis, around the look-at point:
camera.setYawRotationMode();   // like spinning a globe
camera.setPitchRotationMode(); // like a somersault
camera.setRollRotationMode();  // like a radio knob
camera.setSuppressRollRotationMode();  // Permit pitch/yaw only.

// Then you can set it back to its default mode:
camera.setFreeRotationMode();

Thanks, Charles

I made the HUGE mistake of developing on my mac machine and testing only now on the target machine, a windows 8.1 computer. My code doesn't work and it's clearly an error of the Sound Library (I am trying to run the examples and they crash too). "Target VM failed to initialised" if I try to run any of the example sketches.

Now I am confused because in the GitHub of the library it's written that it's only MacOSX and Linux, but then I find people reporting other type of errors. Plus, on the release note of the 1.3.2 version it's clearly state they fixed some windows related problem.

What's the status of this library? Is it supposed to work on Processing 64-bit, and on Windows 8.1? If not, is there any type of workaround? I am reading that maybe downgrading it to 1.2.1 could work but I wasn't able to install it. Thanks for the support

im trying to get rotation angles from shapes3d to use them in maya python scripting. as i know, maya uses euler angles and shapes3d can give me them in some order (e.g. RotOrder: ZYZ).

i can change/define the RotationOrder at MEulerRotation, but they are different (e.g. kZYX) i tried different ways, but the rotations always look wrong.

any ideas?

thanks.

Looking to find a function code in processing that will not only loop a series of short videos, but also be affected when a mouse scrolls over the media from one side to the other horizontally. Speed of the mouse movement then translates to the speed of the video. I'm trying to find a way to do this with a distance sensor but I think keeping a mouse will be more simple. Would really appreciate any help!

Anyone familiar with a way to get some sort of trigger from the ControlP5 Matrix for when a position hasn't been set?? It's working just fine to let me know anytime I have a section activated, but I'm building a basic A/B image animation flipping tool– and beyond using it to flip between the two images, would love to have it show black if neither A or B image has been activated. I simply can't find any documentation for even finding out what position the runner is on at any given moment- since it really only sends back signals to its own callback or the main controlEvent– if something happened/triggered. This makes perfect sense... but isn't so helpful right now... Maybe @sojamo you have some advice on how to extend it so that I can pass along another variable within the following code to know where the runner/cnt is and check if it's blank at that moment?? Or simply have the following 'myMatrix' function trigger on every cnt/frame of the Matrix, giving true/falses? I can getCells() to know which ones are blank.. but can't react in realtime when the matrix is playing.

void myMatrix(int theX, int theY) { println("got it: "+theX+", "+theY); // whatabout where it wasn't active? }

Here is what I mean by having one matrix frame inactive and wanting to trigger something for it being blank:

I'm having an issue with passing a variable off to a second variable so that I can reset the slider/value of the first variable, print a number of frames, and then reload the slider with the original value. It seems the variables are so synced that it gets updated early, rendering the whole task useless. rl1 and Darks1Value are both global variables.

rl1 = Darks1Value; //Darks1Value is a slider that will be set to 0, then repopulated with its original value.
cp5.getController("rl1").setValue(Darks1Value);  //rl1 is the temporary variable/slider to store the Darks1Value slider value
cp5.getController("Darks1Value").setValue(0);  //resetting the slider to 0
println("Darks1Value is:"+rl1);  //Darks1Value returns 0 - as it should
println("rl1 is:"+rl1);`  //rl1 should return the original Darks1Value (eg. 100), yet returns 0

Any ideas on this one please? Many thanks.

deleted question - just needed to place startFrame and endFrame in different places in the code. Moderators - please feel free to delete as I can't find how to do this. Thank you.

Hi,

My sketch is setup to run under P2D: size(1920,1080,P2D);

I'm using beginRecord(PDF, etc) & endRecord(); to output a PDF from 1 single frame.

If I draw shapes dynamically they appear in the PDF no problem using beginShape(), vertex(), endShape().

However if I create a PShape object and create a shape that way (which is more efficient) then that shape does not appear in the PDF but does appear on screen.

I'm guessing this is something to do with the way the P2D OPENGL works, but just want to see if it's intended behaviour or a "bug".

Any insight to help me understand this better would be great.

(BTW, I realise there is also a PDF mode, but ideally I'd like a screen preview too?)

Thank

Mike

Hi. I have a way to get weather info, but it does not work well. Do you have a way to get weather info? Also, the library YahooWeather does not work, so please do not suggest it. Thanks in advance!

Hi,

I am currently working on a university final year project, where I am taking an existing piece of work and adding a useful element to it. I have started building the classic brick breaker game but I am not sure how can i use the speech-to-text library to introduce speech commands into the game, such as 'Run' to start the game and move the paddle by saying 'L' or 'R' (Left and Right).. I would like to configure the commands to the amount of pixels the paddle moves across..such as have default commands set as '30 pixels' and further commands such as 'L1' and 'R2' could be used to move a further distance '40pixels' maybe.

Thank you.
