p5.js | keyPressed() Function
The keyPressed() function is invoked whenever a key is pressed. The most recently typed ASCII key is stored into the ‘key’ variable, however it does not distinguish between uppercase and lowercase characters. The non-ASCII character codes can be accessed in the ‘keyCode’ variable with their respective names.
Holding down a key may cause multiple keyPressed() calls. This is due to how the Operating System handles keypressed and depends on how the computer is configured. A browser may have its own default behavior attached to various keys. This can be prevented by adding “return false” to the end of the method.
Parameters: This method does not accept any parameters.
