Adding a Cooldown to a C# script

Questions & Answers
1

I have several scripts I use that have cooldowns on them, I now have a script in C# that I need to behave in the same way but I’m having trouble adding the cooldown to my script:

Here is an example of my working script:

#pragma strict
 
var isPlaying = false;
var coolDown = 1.5;



function Update() {
    if (!isPlaying && Input.GetButtonDown("CreepingDeath")) {
        PlayPS();
    }
}
 
function PlayPS() {
    isPlaying = true;
    particleSystem.Play();
    yield WaitForSeconds(6.0);
    particleSystem.Stop();
    yield WaitForSeconds(coolDown);
    isPlaying = false;
}

Here is what I’ve come up with for my C# script, but I just can’t get it to work:

using UnityEngine;
using System;
using System.Collections;


bool isPlaying = false;
bool coolDown = 1.5f;


public class TriggerWwiseEvent : MonoBehaviour {
	void Update() {
		if (!isPlaying && Input.GetButtonDown("CreepingDeath")){
			PlayPS();
			

		
	}
}



	void PlayPS() {
	isPlaying = true;
	GetComponent<AkTriggerOnKeyPress>().Keypress();
	yield return new WaitForSeconds(coolDown);
    	isPlaying = false;
    }

I’m way more comfortable in Js so any help would be very much appreciated here.

There are a few things wrong with you C# conversion. I recommend you look into the basics of OOP and bear in mind that ALL methods and variables MUST belong to a class.

Not sure whether you wanted you PlayPS() method to more closely resemble the one in the js script, I’ve created a second method called PlayPSAlt() which follows the same structure as the js version. The normal version mirrors the one in your attempted C# conversion.

This solution makes use of Coroutines, which you may want to read into.

using UnityEngine;
using System;
using System.Collections;

public class TriggerWwiseEvent : MonoBehaviour {
	private float coolDown = 1.5f;
	private bool isPlaying = false;
	
	void Update() {
		if (isPlaying && Input.GetButtonDown("CreepingDeath")){
			StartCoroutine("PlayPS");
		}
	}

	IEnumerator PlayPS() {
		GetComponent<AkTriggerOnKeyPress>().Keypress();
		isPlaying = true;
		yield return new WaitForSeconds(coolDown);
		isPlaying = false;
	}

	IEnumerator PlayPSAlt()
		//Closer to function in original javascript
		particleSystem.Play();
		isPlaying = true;
		yield return new WaitForSeconds(6.0f);
		particleSystem.Stop();
		yield return new WaitForSeconds(coolDown);
		isPlaying = false;
	}
}

using UnityEngine;
using System;
using System.Collections;

 public class TriggerWwiseEvent : MonoBehaviour {

 bool isPlaying = false;
 bool coolDown = 1.5f;
 
     void Update() {
         if (!isPlaying && Input.GetButtonDown("CreepingDeath")){
             StartCoroutine(PlayPS());
             
 
         
     }
 }
 
 
 
     IEnumerator PlayPS() {
     isPlaying = true;
     GetComponent<AkTriggerOnKeyPress>().Keypress();
     yield return new WaitForSeconds(coolDown);
         isPlaying = false;
     }

With C# you need to use StartCoroutine and IEnumerator when creating functions that use yield. The above script should fix your problem and show you how it all works :slight_smile:
