Question by vermosapien · Dec 08, 2017 at 07:52 PM · idle animations

Detect no keys pressed for x amount of time

This might seem like a relatively simple question, but I'm a complete idiot and I'm at my wits' end trying to do extremely basic code. I'm trying to make a character swap to an idle animation after x amount of time of being idle, but I can't even achieve a simple test print function with

 void Update () {
     if (Input.anyKeyDown == false) {
         print("hello");
     }

without it printing repeatedly due to it updating every frame. How do I make it detect my input (or lack thereof) over a period of time and only do something once?

 public float inactivityThreshold = 5f ;
 private float lastActivityTime ;
 private bool inactive;

  void Update ()
  {
     if (Input.anyKeyDown)
     {
          inactive = false ;
          lastActivityTime = Time.time ;
     }
     if ( !inactive && Time.time - lastActivityTime > inactivityThreshold )
     {
          inactive = true ;
          Debug.Log("Inactive") ;
     }
  }

This functioned exactly how I wanted, thank you. I can't even understand exactly why it works, sadly.

Alright it took me a while but I finally grasped the logic behind the code. I clearly don't have the brain for program$$anonymous$$g. Thank you for a swift response.
