Error: error on "int"

I'm new to Processing and I need to create a random color, but it returns an error.

int R = (int)(Math.random()*255);
int G = (int)(Math.random()*255);
int B = (int)(Math.random()*255);
color randomColor = new color(R,G,B);

The final line in this returns error on "int" Did I not write the last line properly?

Solution

  • The other answers don't realize that color is a type in Processing.

    Your problem is that you're trying to use a new color() constructor, which doesn't exist. Try using the color() function, like this:

    color randomColor = color(R,G,B);

    More info can be found in the reference.

    Also note that Processing has its own random() function that you should be using instead of directly calling Math.random() yourself.

    Edit: Turns out other people have been confused by this, and here is a discussion on implementing better error messages.
