Hi all, I have had this question for a long time: Is there any way to make processing act as if the user pressed a key?

Ex: When a condition is true, the script would send a signal to the computer that the “P” key had just been pressed on the keyboard, and the computer would react accordingly.

Any and all advice appreciated. Thanks!

You could trigger the code yourself, something like:

```auto
void keyPressed(){
  if(key == 'p'){
    myFunction();
  }
}

void mousePressed(){
  myFunction();
}

```

This code calls the `myFunction()` function when the user presses `P` or presses the mouse. The computer doesn’t really need to know the difference.

You could also look into the `Robot` class in Java, which can generate mouse and keyboard events.
