mouseMoved() / Reference / Processing.org

Name

mouseMoved()

Description

The mouseMoved() function is called every time the mouse moves and a mouse button is not pressed. (If a button is being pressed, mouseDragged() is called instead.)

This function can be called with or without a MouseEvent parameter. When called with the parameter, you get access to additional information about the mouse event, including the exact coordinates and any modifier keys that were held down.

Mouse and keyboard events only work when a program has draw(). Without draw(), the code is only run once and then stops listening for events.

Examples

// Move the mouse across the image
// to change its value

int value = 0;

void draw() {
  fill(value);
  rect(25, 25, 50, 50);
}

void mouseMoved() {
  value = value + 5;
  if (value > 255) {
    value = 0;
  }
}

Syntax

mouseMoved()
mouseMoved(event)

Parameters

event(MouseEvent)the MouseEvent

Return

void
