Function such as DRAW and SETUP?

netrate

As the DRAW and SETUP when used as functions, are they command words? Is there a case where you can make up your own function names (such as in python)? Is there a list of FUNCTION names in a glossary?

• setup() & draw() are methods of Processing's class PApplet.
• And they are automatically called back by the sketch's "Animation" Thread.
• Unfortunately, we can't specify another method to replace any of those callbacks.
• However, we can invoke other methods from within them. *-:)

Next to setup() and draw() there are other functions that get called automatically: keyPressed(), keyReleased(), mousePressed(), mousereleased(), mouseWheel() etc. - see reference. They all have written () after the name (which says I am a function and not a variable).

(It is not recommended to call setup() and draw() and the others manually as in writing their title to call them since they're called automatically.)

But you can of course define your own functions like

void initGame() {

}

and call it by saying initGame(); eg. in draw() or elsewhere
