Unexpected token: void()

million_of_peaches

Hi, I'm (really) new with processing. Can anyone help me with this code? please :) I cannot find why I get unexpected token: void() in this code:

import processing.video.*; Capture webcam; int w=400; int h=400; int pixn=w*h; int keyhits; PImage img; int i= 0

void setup() { size(w, h); webcam = new Capture(this, 400, 400); webcam.start(); loadPixels(); }

void captureEvent(Capture webcam) { webcam.read(); } void draw() { image(webcam, 0, 0); }

void keyPressed() {

if ( key == '1' ) { save("capture" + ++keyhits + ".jpg"); }

img = loadImage("capture"+keyhits+".jpg"); int x = int(img.width); int y = int(img.height); float r = red(img.pixels[i]); float g = green(img.pixels[i]); float b = blue(img.pixels[i]);

for (int i=0; i<pixn; i++) { float sumar = sumar + red(img.pixels[i]); float sumag = sumag + green(img.pixels[i]); float sumab = sumab + blue(img.pixels[i]); }

float mediar = sumar / pixn); float mediag = sumag / pixn); float mediab = sumab / pixn);

if ( key == '2' ) { fill(mediar, mediag, mediab, 255); rect(0, 0, 400, 400); save("average_color"+ keyhits + ".jpg"); } }

First of all you need to learn to format your code for this forum. Look here

There are several errors in your code. The first is in line 8 where the statement int i = 0 needs a semicolon

Then the variables sumar, sumag and sumab are declared local to the for loop and have not been initialised before use.

Then you have extra unneeded )

The corrected code looks like

import processing.video.*;
Capture webcam;
int w=400;
int h=400;
int pixn=w*h;
int keyhits;
PImage img;
int i= 0;


void setup() {
  size(w, h);
  webcam = new Capture(this, 400, 400);
  webcam.start();
  loadPixels();
}

void captureEvent(Capture webcam) {
  webcam.read();
}
void draw() {
  image(webcam, 0, 0);
}

void keyPressed() {

  if ( key == '1' ) {
    save("capture" + ++keyhits + ".jpg");
  }

  img = loadImage("capture"+keyhits+".jpg");
  int x = int(img.width);
  int y = int(img.height);
  float r = red(img.pixels[i]);
  float g = green(img.pixels[i]);
  float b = blue(img.pixels[i]);
  float sumar = 0, sumag = 0,  sumab = 0;
  for (int i=0; i<pixn; i++) {
    sumar = sumar + red(img.pixels[i]);
    sumag = sumag + green(img.pixels[i]);
    sumab = sumab + blue(img.pixels[i]);
  }

  float mediar = sumar / pixn;
  float mediag = sumag / pixn;
  float mediab = sumab / pixn;


  if ( key == '2' ) {
    fill(mediar, mediag, mediab, 255);
    rect(0, 0, 400, 400);
    save("average_color"+ keyhits + ".jpg");
  }
}

And you haven't formatted the code properly.
