p5.js keyTyped() Function

The keyTyped() function is invoked every time when a key is pressed, except for action keys like the directional arrow keys, Ctrl, Shift, Alt, Backspace and the Delete key. The most recently typed key is stored in the ‘key’ variable.

Note that, holding down a key may cause multiple keyTyped() calls. This is due to how the Operating System handles keypresses and depends on how the computer is configured. A browser may have its own default behavior attached to various keys which can be prevented by adding “return false” to the end of the method.

Syntax:

keyTyped()

Parameters: This method does not accept any parameters.

Below example illustrates the keyTyped() function in p5.js:

Example:

function setup() {
  createCanvas(600, 200);
  textSize(20);
  text("Press any key to display it on the screen", 10, 20);
  text("Any of the action keys would not be recognized", 10, 40);
}

function keyTyped() {
  clear();
  textSize(20);
  text("Press any key to display it on the screen", 10, 20);
  text("Any of the action keys would not be recognized", 10, 40);
  textSize(100);
  text(key, 100, 150);
}
