So I'm new to processing and been trying to teach myself but I'm stuck here:

 

 

int CircleX = 0;
int CircleY = 0;

void draw() {
  background(255,0,0);
  CircleX = CircleX + 1;
  CircleY = CircleY + 1;
  ellipse(CircleX,CircleY,20,20);
  if(CircleX=5);
  background(0,0,255);
}

I'm wondering why when I use the if(CircleX=5); it says can not convert from int to Boolean. Does it mean it cannot use the CircleX inside the if(command)? Also I tried putting it outside with it looking like:

 

int CircleX = 0;
int CircleY = 0;

void draw() {
  background(255,0,0);
  CircleX = CircleX + 1;
  CircleY = CircleY + 1;
  ellipse(CircleX,CircleY,20,20);
}

  if(CircleX=5) {
        background(0,0,255)

}
But then it says looking for EOF found "if". Any ideas for how to get this to work.

Sorry for the beginner question.
