could anyone plz help, all i am trying to do is to get the background colour to flash a different colour using the line in. i have started it by trying to do an if statement, but it can not convert to boolean.
import toxi.geom.*;
ArrayList ballNetwork;
import ddf.minim.*;
Minim minim;
AudioInput in;
void setup(){
size(1300,300);
smooth();
ballNetwork = new ArrayList();
minim = new Minim(this);
minim.debugOn();
in = minim.getLineIn(Minim.STEREO, 512);
for (int i = 0; i < 150; i++){
Vec3D origin = new Vec3D(random(width),random(200),0);
ball myBall = new ball(origin);
ballNetwork.add(myBall);
}
}
void draw(){
background(#62AFFA);
if(in = true);
background(0);
for(int i = 0; i < ballNetwork.size(); i++) {
ball mb = (ball) ballNetwork.get(i);
mb.run();
}
}
void stop()
{
// always close Minim audio classes when you are done with them
in.close();
minim.stop();
super.stop();
}

for (int i = 0; i < ballNetwork.size(); i++) {
