A function that's called once when the sketch begins running.
Declaring the function setup()
sets a code block to run once automatically when the sketch starts running. It's used to perform setup tasks such as creating the canvas and initializing variables:
function setup() {
// Code to run once at the start of the sketch.
}
Code placed in setup()
will run once before code placed in draw() begins looping. If the preload() is declared, then setup()
will run immediately after preload() finishes loading assets.
Note: setup()
doesn’t have to be declared, but it’s common practice to do so.
