We can further improve our rom by adding some simple sound effects
The beep function offers a convenient means of triggering sounds - it requires frequency, duration, and force arguments to be provided (the first two being integers and the last being a boolean). The frequency parameter is the beep’s frequency (measured in hertz), the duration parameter is how long the beep should play for (measured in ticks), and force determines whether or not the beep should override any currently playing beep or not
A short and relatively high pitched beep suits the positive event of eating a piece of fruit, and a longer relatively low pitched beep suits the negative event of losing
We’ll simply add calls to beep (with appropriate arguments set) at the relevant points in romLoop:
function romLoop() {
...
if (snake.isDead()) {
beep(280, 15, true);
changeState(states.gameOver);
}
if (snake.body[0].equals(fruit)) {
beep(1000, 5, true);
...
