Static p5_sys::global::random

pub static random: RandomInternalType

Return a random floating-point number.

Takes either 0, 1 or 2 arguments.

If no argument is given, returns a random number from 0 up to (but not including) 1.

If one argument is given and it is a number, returns a random number from 0 up to (but not including) the number.

If one argument is given and it is an array, returns a random element from that array.

If two arguments are given, returns a random number from the first argument up to (but not including) the second argument.

Examples

for (let i = 0; i < 100; i++) {
  let r = random(50);
  stroke(r * 5);
  line(50, i, 50 + r, i);
}

for (let i = 0; i < 100; i++) {
  let r = random(-50, 50);
  line(50, i, 50 + r, i);
}

// Get a random element from an array using the random(Array) syntax
let words = ['apple', 'bear', 'cat', 'dog'];
let word = random(words); // select random word
text(word, 10, 50); // draw the word
