The goal is to create a code that allows you to choose the color of a shape (in this case an ellipse, and using red,green,and blue) by using keyPressed, and then to be able to click on the screen and have an ellipse show up in a random part of the screen. Everything is working except for the color selector(i.e. the keyPressed function).


int r;
int g;
int b;
int x;
int y;

void setup(){
  size(600,600);
  background(251,255,49);
}

void draw() {
}


void keyPressed() {
 
  println(key);
 
  switch(key) {
  case 'r':
  case 'R':
    r = 255;
    g = 0;
    b = 0;
    break;
  case 'g':
  case 'G':
    r = 0;
    g = 255;
    b = 0;
    break;
  case 'b':
  case 'B':
    r = 0;
    g = 0;
    b = 255;
    break;
  default:
    break;
  }
}

void drawShape(int x, int y){
  ellipse(x,y,25,25);
}
