I’m building a code that will allow you to recognize color cards and, depending on the color, a drawing will appear in the drawing area.
Example:
red = red round
blue = blue round
green = green square
I was able to define my areas, but I can not ask him to display a shape when he tracks the right color.
I show you my code, my English is not great I hope you understand.
import processing.video.*;

color(0, 255, 0),
color(255, 255, 0)};
//color red = color(0,100,100);

}
My problem occurs at this time.
void couleurCible1(color c_) { // affichage de la couleur ciblé
cible = c_;
noStroke();
fill(c_);
rect(20, 20, 20, 20);
r = color(0, 100, 100);
if(cible == r); {
//fill(0,100,100);
rect( width/1.5, height/2.8, 150, 150);
Any tips, or examples.
Thank you for your help.
