Processing Java: How do you detect if the mouse was dragged through a variable

I understand that code inside Processing's mouseDragged() function will run if the mouse is moved and pressed at the same time. I was wondering how I could detect such movement through a variable since Processing doesn't provide a corresponding variable for mouseDragged() unlike mousePressed(). Thanks!

There is https://processing.org/reference/mouseMoved_.html which sounds like the right thing.

A solution specific to Processing would be to create the variable that stores whether the user dragged the mouse or not. Under mouseDragged(), the variable is set to true. Inside the draw() function, if the mouse is not pressed, the variable is set to false.

Example:

boolean mouseDragged = false;

void draw()
{
    if (mousePressed == false)
    {
        mouseDragged = false;
    }

    println(mouseDragged);
}

void mouseDragged()
{
    mouseDragged = true;
}

You need the MouseMotionListener instead. It has two methods:

  1. Mousedragged
  2. MouseMoved
