How to check if no buttons are pressed for a specific time?

Question

 float timeVariable = 0f;
 
 void Update () {
 if ( canCheck == true){
 timeVariable = Time.time + 5;
 Do{
 //nothing until time has passed
 }while ( Time.time < timeVariable && Input.AnyKey == false)
 If (Time.time >= timeVariable){
 //do stuff
 }

Am I wrong or what? Without the Do/While, I can tell that timeVariable is always the same as Time.time, So how do I do this?

This code should hopefully fit your needs

                  public int time = 0;    
         
                 //Use fixed update beacuase its called every fixed framerate frame
                  void FixedUpdate () {
     
                     if(!Input.anyKey){
                         
                         //Starts counting when no button is being pressed
                         time = time + 1;
                     } else {
                         
                         // If a button is being pressed restart counter to Zero
                         time = 0;
                     }
                     
              //Now after 100 frames of nothing being pressed it will do activate this if statement
                     if(time == 100) {
                         Debug.Log("100 frames passed with no input");
                         
                         //Now you could set time too zero so this happens every 100 frames
                         time = 0;
                     }
     
                 }

you can use this for actual time in seconds

 public float timer = 0;
 
     void FixedUpdate () {
 
         if(!Input.anyKey){
             timer += Time.deltaTime;
         } else {
             timer = 0;
         }
         
         if(timer >= (TIME IN SECONDS)) {
             //your code
             timer = 0;
         }
 
     }

You would need to start a coroutine to increment a timer and evaluate some bools when the timer has begun and elapsed, this may not solve your problem directly but I believe the framework should help you reach a solution of your own. I also tried to comment it as best as I could for clarity, hopefully this should allow you to write your own similar code that fits within the script you're using.

 using UnityEngine;
 using System.Collections;
 
 public class ButtonTimer : MonoBehaviour {
 
     public float inputTimer; //the timer begins at 0
     public float frequency; //the frequency the timer is checked, if you need to check the timer more frequently then try 0.5f or 0.25f or even 0.1f, but 1f should be sufficient.
     public float timeLimit; //the limit of the timer 
 
     public bool timing;
     public bool noInput;
 
     void Start () { //none of these things need to be set at start, they can be set elsewhere if need be
     
         inputTimer = 0f;
         frequency = 1f;
         timeLimit = 5f;
 
     }
 
     void Update () {
 
         if (!noInput && !timing) { //first, the script makes sure the timer hasn't already begun or elapsed
                 if (!Input.anyKey) { //then, if there is no input
                     timing = true; //the timing begins
                     StartCoroutine ("InputTimer"); //and the coroutine is called
                 }
             }
 
          if (Input.anyKey) { //if input is ever detected
             timing = false; //the timing ends
             noInput = false; //the "noInput" status is reset (if it had been activated in the first place)
             inputTimer = 0f; //the timer is also reset to 0, this is useful if the timer needs to be accessed by another portion of the script but this can be removed because the timer also sets itself to 0 at the start of the coroutine
             StopCoroutine ("InputTimer"); //and the coroutine is ended
         }
     }
 
     IEnumerator InputTimer () {
 
         inputTimer = 0f; //timer resets at the start of the coroutine
 
         while (timing) { //only workins while timing
             while (inputTimer < timeLimit) { //while the timer is below the timeLimit
                 inputTimer += frequency; //the timer counts upward at the same rate it is checked
                 yield return new WaitForSeconds (frequency); // 1 second is sufficient but it can check every half or quarter or whatever you need
             }
 
             if (inputTimer >= timeLimit) { // once the timer has exceeded the timeLimit
                 noInput = true; //it tells the script that there has been no input
                 timing = false; //stops timing (because there's no need once it has determined there's no input)
                 Debug.Log ("No input!"); //I just left this here while testing
                 yield return noInput; 
             }
         }    
     }
 }

EDIT: I forgot to mention it initially, but this only works for key and button inputs. Mouse movement is not counted.
