Animate only after certain time

Hello everyone,

I have a tank that always animates its “Scanning/waiting” animation when no key is pressed. I want it to play its scanning animation only after a certain amount of time has passed after having not pressed a key.

So how do I measure the time elapsed after having pressed a certain key?

I’m using JavaScript for this project by the way, but I can also use C#.

I know it may have something to do with Time.time, but I can’t get my head around it.

Any help appreciated-Hyperion

using UnityEngine;
using System.Collections;

public class time : MonoBehaviour {
	
	public bool idle = false;
	public float timeToIdle = 2.0f; //2 seconds
	float currentTime = 0f;
	
	// Use this for initialization
	
	void Start () {
	currentTime = Time.time + timeToIdle;
	}
	
	// Update is called once per frame
	void Update () {
	
		if(!idle) //this can be replaced by something to check if there is no input etc..
		{
			checkIdle();
		}
	}
	
	void checkIdle()
	{
		if(Time.time > currentTime)
		{
			idle = true;
			//run your anim here or a seperate function to translate the boolean value
			currentTime = Time.time + timeToIdle;
		}
	}
}
