My ControlP5 slider is not responding

in Contributed Library Questions • 11 months ago

As the title says - the slider does not respond to clicks. What to do? Here's my code*:

*it's probably not the neatest of codes, I'm just hacking away at this, like the newbie I am. Might be related to my problem. :)

float r = 75;

float theta = 0;

int t = 1;

int frb=1;

import controlP5.*;

ControlP5 cp5;

int sliderValue = 100;

Slider abc;

void setup() {

size(800, 800);

background(255, 200);

smooth();

frameRate(60);

cp5 = new ControlP5(this);

// add a horizontal sliders, the value of this slider will be linked

// to variable 'sliderValue'

cp5.addSlider("sliderValue")

.setPosition(-300, -300)

.setRange(0, 255)

;

}

void draw() {

sliderValue=frb;

translate(width/2, height/2);

pushMatrix();

background(255); //tried to set alpha very low. didnt work.

translate(1, 1);

for (int i = 1; i<70; i++) {

// Polar to Cartesian conversion

float x = r * cos(theta);

float y = r * sin(theta);

//float x = (sin(frb));

stroke(i/3, 3);

noFill();

//ellipse(pow(x, i/340) + width/2 -random(i*2), y + height/2, i, y);

ellipse(frb, x, 20, y);

rotate(frb/1000);

// Increment the angle

theta += .05;

t = t+1;

}

popMatrix();

}

Would love any help.

Thanks!

Sorted. translate() and rotate() were giving me trouble. If anyone's interested:

float r = 75;

float theta = 0;

int t = 1;

int frb=1;

import controlP5.*;

ControlP5 cp5;

int myColor = color(0, 0, 0);

int sliderValue = 100;

Slider abc;

void setup() {

size(800, 800);

// background(255, 200);

smooth();

frameRate(60);

cp5 = new ControlP5(this);

// add a horizontal sliders, the value of this slider will be linked

// to variable 'sliderValue'

cp5.addSlider("sliderValue")

.setPosition(50, height-50)

.setRange(0, 100)

;

}

void draw() {

frb=sliderValue;

println(sliderValue);

pushMatrix();

background(255, 1); //tried to set alpha very low. didnt work.

// translate(1, 1);

for (int i = 1; i<70; i++) {

// Polar to Cartesian conversion

float x = r * cos(theta);

float y = r * sin(theta);

//float x = (sin(frb));

stroke(i/3, 3*i, 3, 30);

noFill();

//ellipse(pow(x, i/340) + width/2 -random(i*2), y + height/2, i, y);

ellipse(width/2, height/2, x*i*frb/300, 5*y);

// translate(width/2, height/2);

rotate(i*0.001);

// Increment the angle

theta += .05;

t = t+1;

}

popMatrix();

}
