Final Project Documentation 1

So far, thanks to Scott, I finished making my software. Using this interface, the user can manipulate the three circles (each controls red green or blue) to change the overall colour of light.

The code for this is as follows.

//import processing.serial.*;
//Serial myPort;

Dot myDot0;
Dot myDot1;
Dot myDot2;

void setup() {
  //myPort = new Serial(this, "/dev/cu.usbserial-DA01LL1U", 9600);
  size(600, 400);
  myDot0 = new Dot(width/2.0, height*0.75, 0, 0, 255);
  myDot1 = new Dot(width/2.0, height*0.5, 0, 255, 0);
  myDot2 = new Dot(width/2.0, height*0.25, 255, 0, 0);
  textSize(28);
  ellipseMode(RADIUS);
}

void draw() { 
  
  background(myDot2.getCol(), myDot1.getCol(), myDot0.getCol());
  println("COLOR: " + myDot2.getCol() + " , " + myDot1.getCol() + " , " + myDot0.getCol());
  //myPort.write('1');
  
  myDot0.mapping();
  myDot1.mapping();
  myDot2.mapping();
  
  myDot0.drawLine();
  myDot1.drawLine();
  myDot2.drawLine();
  
  myDot0.cursorTest();
  myDot1.cursorTest();
  myDot2.cursorTest();
  
  myDot0.drawDot();
  myDot1.drawDot();
  myDot2.drawDot();
  
  fill(0);
  text("Change the Color :)", 175, 50);
}

  void mousePressed() {
  myDot0.mouseP();
  myDot1.mouseP();
  myDot2.mouseP();
  }
  
  void mouseDragged() {
  myDot0.mouseD();
  myDot1.mouseD();
  myDot2.mouseD();
  }
  
  void mouseReleased() {
  myDot0.mouseR();
  myDot1.mouseR();
  myDot2.mouseR();
  }

      fill(255, 255, 255);
    } 
    else {

    }
    Offset = mouseX-bx;   
  }
  
  void mouseD() {
       if (locked) {
      bx = mouseX-Offset; 
      if (bx<lowLimit) {
        bx=lowLimit;
      }
      if (bx>hiLimit) {
        bx=hiLimit;
      }
    } 
  }
  
  void mouseR(){
       locked = false; 
  }
  
  void drawDot(){
    fill(c);
    ellipse(bx, by, boxSize, boxSize);  
  }

}

I have experienced a lot of difficulties making this code. Creating a class, making the limits (making sure the circles don’t go outside) and assigning colours to each circle was difficult and Scott helped me get through all these.

I am thinking of introducing default colours such as Interactive Media Pink on the side but for now I will move on to connecting this software to the hardware.
