How do I make a wait?

[applejuices]

ALright, I have a basic gun, just to test my abilities, but I want to make a wait thingy, so 2 secs later I have ammo. How would I make a wait thingy? (I have tried waitforseconds no mater what I do it errors) ALso please try to make it like one line short. This is in CShrap, and is under void update()

It’s easy once you get past all the oddly named functions:

You need to keep a flag in your update: bool waitingToReload

if(waitingToReload != true){
StartCoroutine(fireGun( waitingTime ));
}

make your waitingTime 2 seconds or whatever. Then declare an IEnumerator function. check the tutorial, they are good to learn from.

IEnumerator fireGun(float waitTime){

    waitingToReload = true;

      //you can do other stuff here too

      yield return new WaitForSeconds (waitTime);

     //or you can do it here too

      waitingToReload = false;

}

You can’t yield in Update(). You must use Invoke, or InvokeRepeating to invoke a function, or use a Coroutine.

Invoke Example:

using UnityEngine;
using System.Collections;

public class InvokeExample : MonoBehaviour 
{
	void Start()
	{
		Invoke ("Count", 3);
	}

	void Count()
	{
		print ("Count function invoked!");
	}
}

InvokeRepeating Example:

using UnityEngine;
using System.Collections;

public class InvokeRepeatingExample : MonoBehaviour 
{
	int count = 0;

	void Start()
	{
		InvokeRepeating("Count", 1, 1);
	}

	void Count()
	{
		count++;
		print (count);
	}
}

Coroutine Example:

using UnityEngine;
using System.Collections;

public class CoroutineExample : MonoBehaviour 
{
	int count = 0;

	void Start()
	{
		StartCoroutine(Count ());
	}

	IEnumerator Count()
	{
		while(true)
		{
			count++;
			print (count);
			yield return new WaitForSeconds(1);
		}
	}
}

Say you want to fire by clicking left mouse, then wait 1 second before you may fire again, here’s how you’d do that using a Coroutine, my method of choice in this case.

using UnityEngine;
using System.Collections;

public class WaitToFireExample : MonoBehaviour 
{
	bool canFire = true;

	void Update()
	{
		if(canFire && Input.GetMouseButtonDown(0))
		{
			canFire = false;
			StartCoroutine (WaitToFire(1));
		}
	}

	IEnumerator WaitToFire(float t)
	{
		print (canFire);
		yield return new WaitForSeconds(t);
		canFire = true;
		print (canFire);
	}
}
