How do I correct This?

When I try to run this code, it comes up with: The Constructor sketchapr15b.soundcircle

(int, int, int, AudioPlayer) is undefined.

What does this mean?

Here is my code:

import ddf.minim.*;

import ddf.minim.signals.*;

import ddf.minim.analysis.*;

import ddf.minim.effects.*;

class SoundCircle

{

int w;

int h;

float xPos;

float yPos;

float ySpeed;

}

Minim m;

SoundCircle circ;

void setup(){

size(500,500);

smooth();

frameRate(1000);

m = new Minim(this);

AudioPlayer player = m.loadFile("Explosion.mp3");

circ = new SoundCircle(250,250,100,player);

}

void draw(){

if(circ.isOver(mouseX, mouseY)){

circ.play(dist(mouseX,mouseY,pmouseX,pmouseY));

}

background(255);

circ.draw();

}

//void mousePressed(){

// if(circ.isOver(mouseX, mouseY))

// circ.play();

//}

It cannot find the constructor because it does not exist. If you are not familiar with constructors, you need:
(inside the class)

<className(In your case, SoundCircle)>(parameters) {
<Initialize Stuff here>
}

Just like a function, except no return value and must have class name
the parameters are specified the same way, too.

So this is my code now:

It just comes up with unexpected token : (

(shown on here as the yellow bracket)

import ddf.minim.*;

import ddf.minim.signals.*;

import ddf.minim.analysis.*;

import ddf.minim.effects.*;

class SoundCircle

{

<SoundCircle> (parameters)

int w;

int h;

float xPos;

float yPos;

float ySpeed;

}

Minim m;

SoundCircle circ;

void setup(){

size(500,500);

smooth();

frameRate(1000);

m = new Minim(this);

AudioPlayer player = m.loadFile("Explosion.mp3");

circ = new SoundCircle(250,250,100,player);

}

void draw(){

if(circ.isOver(mouseX, mouseY)){

circ.play(dist(mouseX,mouseY,pmouseX,pmouseY));

}

background(255);

circ.draw();

}

//void mousePressed(){

// if(circ.isOver(mouseX, mouseY))

// circ.play();

//}

Sorry, I was giving you an outline of what it should look like.

class SoundCircle
{
int w;
int h;
float xPos;
float yPos;
float ySpeed;
SoundCircle(int a, int b, int c, AudioPlayer d) {
//Initialize stuff here
}
}

It will find your constructor, now. But I'm not sure what those values are supposed to be...

Hay thanx, that fixes that. but now it comes up with: found too many {characters without } to match it.

Sorry to keep bothering you, not too good at this.

I cant figure out where the extra {'s or }'s are

my code is now:

import ddf.minim.*;

import ddf.minim.signals.*;

import ddf.minim.analysis.*;

import ddf.minim.effects.*;

class SoundCircle

{

int w;

int h;

float xPos;

float yPos;

float ySpeed;

SoundCircle(int a, int b, int c, AudioPlayer d){

}

Minim m;

SoundCircle circ;

void setup(){

size(500,500);

smooth();

frameRate(1000);

m = new Minim(this);

AudioPlayer player = m.loadFile("Explosion.mp3");

circ = new SoundCircle(250,250,100,player);

}

void draw(){

if(circ.isOver(mouseX, mouseY))

circ.play(dist(mouseX,mouseY,pmouseX,pmouseY));

background(255);

circ.draw();

}import ddf.minim.*;

import ddf.minim.signals.*;

import ddf.minim.analysis.*;

import ddf.minim.effects.*;

class SoundCircle

{

int w;

int h;

float xPos;

float yPos;

float ySpeed;

SoundCircle(int a, int b, int c, AudioPlayer d){

}

Minim m;

SoundCircle circ;

void setup(){

size(500,500);

smooth();

frameRate(1000);

m = new Minim(this);

AudioPlayer player = m.loadFile("Explosion.mp3");

circ = new SoundCircle(250,250,100,player);

}

void draw(){

if(circ.isOver(mouseX, mouseY))

circ.play(dist(mouseX,mouseY,pmouseX,pmouseY));

background(255);

circ.draw();

}

Oh wait, fixed that. but now it comes up with:

The Constructor Minim(sketchapr15b.soundcircle) is undefined.

The 'this' given to the Minim constructor must be a reference to the main class (PApplet), not to your internal class.
A way to workaround this (no pun) is to call it with:
m = new Minim(this.getClass().getEnclosingClass());
