List of system variables

p5.js Beginners
1

Does anyone know if there’s a list of system variables somewhere in the p5 docs? I found this page in the docs that goes over mouseX and mouseY, but the AI overview from a quick Google search also pulls up a ton of others that I’m not seeing listed out:

  • mouseX: Current horizontal location of the mouse pointer.

  • mouseY: Current vertical location of the mouse pointer.

  • pmouseX: Previous horizontal location of the mouse pointer (from the last frame).

  • pmouseY: Previous vertical location of the mouse pointer (from the last frame).

  • mouseIsPressed: A boolean value that is true when a mouse button is pressed and false otherwise.

  • Keyboard-related:

    • key: The character of the last key pressed.
    • keyCode: The numeric Unicode value of the last key pressed, especially useful for special keys like arrow keys or Enter.
    • keyIsPressed: A boolean value that is true when any key is pressed and false otherwise.

  • Canvas and Window dimensions:

    • width: The width of the drawing canvas.
    • height: The height of the drawing canvas.
    • windowWidth: The width of the browser window.
    • windowHeight: The height of the browser window.

  • Other:

    • frameCount: The number of frames that have been drawn since the sketch started.
    • focused: A boolean value indicating whether the sketch canvas currently has input focus.
    • drawingContext: Provides direct access to the underlying HTML5 CanvasRenderingContext2D object for advanced drawing operations not directly available in p5.js.
