What is a possible way of having a cool-down timer for a weapon?

Please consider that all my work is in C#.

Thanks in advance!

One easy way is to use a what I call a time stamp. Anytime you want a cool down you would do something like:

 timeStamp = Time.time + coolDownPeriodInSeconds;

The in your firing code, you would only allow the gun to fire if the timeStamp

 if (timeStamp <= Time.time)
 {
 // Your firing code
 }

Amazing, dude! Thanks! I like your Time Stamp theory, might consider referring it to my friends too. You are awesome!

@robertbu what do timeStamp and cooldown perdiods in second stand for?

'timeStamp' is a float declared at the class level. In Javascript it would be:

  private var timeStamp : float;

...in c# it would be:

  private float timeStamp;

'coolDownPeriodInSeconds' is the number of seconds for the cooldown. You can replace it with a constant like 2.5, or you can declare it as a variable, and assign it a value.

WHERE DO WE PLACE THE$$anonymous$$ ON THE SCRIPT?

Initialize the variables at the top of the script, then when you want to start the timer, do timeStamp = Time.time + coolDownPeriodInSeconds;. When you're getting the input from the player, only do the ability if(Time.time <= timeStamp)

In my opion, this is way better than timestamps.

Simple example using a proper coroutine.

     public bool IsAvailable = true;
     public float CooldownDuration = 1.0f;
     
     void UseAbility()
     {
         // if not available to use (still cooling down) just exit
         if (IsAvailable == false)
         {
             return;
         }
         
         // made it here then ability is available to use...
         // UseAbilityCode goes here
         
         // start the cooldown timer
         StartCoroutine(StartCooldown());
     }
     
     public IEnumerator StartCooldown()
     {
         IsAvailable = false;

         yield return new WaitForSeconds(CooldownDuration);

         IsAvailable = true;
     }

You can also use Coroutines in unity. They aren't that hard to use and save you a lot of time in the future if you plan to have multiple cool downs going on. Here's an Example:

 void Update()
 {
      StartCoroutine(TimerRoutine());
 }
 
 private IEnumerator TimerRoutine()
 {
      //code can be executed anywhere here before this next statement 
      yield return new WaitForSeconds(5); //code pauses for 5 seconds
     //code resumes after the 5 seconds and exits if there is nothing else to run
 
 }

I recommend looking into Coroutines because you can do a lot with them.
