Hi there

Just a quick one, which I cannot fathom. I have a function which creates an object (an ellipse) and I want to pass in the fill value as a hex. How do I do this, I have tried passing in a string and then performing Integer.parseInt(string, 16) and passing in a char[] of the hex value but to no avail.

This is my code:


public circle(int x, int y, int d, char[] c)

{
      this.colour = new char[6];
      this.xpos = x;
      this.ypos = y;
      this.dimension = d;
      this.colour = c;
}

With the function being:


public void display()

{
    noStroke();
    smooth();
    fill(colour);
ellipse(this.xpos,this.ypos,this.dimension,this.dimension);

}

Sorry if this is documented, I have checked the documentation and investigated how to handle this with Java but I cannot see how to do it.

Perfect, thank you PhiLho. That is what I was looking for.

Now, I have a second question. I am struggling with colorMode. If I pass in the value of "FF3333" this equates to 16777011 as an int (which is cool). However, I don't get the warm red I would expect I get a grey color.

I have set (under void setup()) the colorMode(RGB,16777215); (I have previously set colorMode(RGB,255).

I am struggling to understand why I can't get colors via integers? I am setting the fill value in a method belonging to a class which is instantiated in void setup().  I think I am missing something quite fundamental with colorMode?

The method is:


public void display()

{


noStroke();


smooth();
println("Colour = "+this.colour);
               int c = unhex(this.colour);
println("C = "+c);
               fill(c);
               //fill(#FF3333);


ellipse(this.xpos,this.ypos,this.dimension,this.dimension);

}

P.s. If I use fill(#FF3333) I get the warm color I want with colorMode(RGB,255);
