Let's say we have an attack method in our game for the player. When the player presses a key, we want to attack. But we also want to apply a cooldown when the player attacks to prevent the player from attacking too quickly.

First let's declare a Cooldown for the attack and call it "attackCooldown"
Also, let's declare a float variable for the amount of seconds between attacks. Let's say we want the duration of the cooldown to be 3.25 seconds.

float attackCoodldownDuration = 3.25f;
Cooldown attackCooldown;

Now to initialize it. All you got to to is to call its constructor.
When you initialize a Cooldown object, you set its default duration value.
And it's the float variable we declared before.
Make sure you initialize your cooldowns inside Start() or Awake()

void Awake()
{
  attackCooldown = new Cooldown(attackCooldownDuration);
}

Done. The cooldown is ready.
Let's activate it when we attack. We just need to use the method Activate()

void Attack()
{
  // some attack behaviour
  ...
  // cooldown activation
  attackCooldown.Activate();
}

Now, let's prevent the player from attacking if the cooldown is active.
We can do this by checking the value IsActive in the cooldown.

if (//player is pressing the attack button)
{
  if (attackCooldown.IsActive == false)
  {
    Attack();
  }
}

A Cooldown object contains two properties. A timer and a default duration.
The Cooldown is considered "active" when its timer equal to zero.
The timer is always decreasing until it reaches zero.
Let's say we want to add a special, shorter attack, and apply a short cooldown for it with a different duration.
We can do it with the Activate() method by inputting a custom duration to it.

void SpecialAttack()
{
  // some attack behaviour
  ...
  // cooldown activation
  attackCooldown.Activate(1.7f); // cooldown applied with a custom duration.
}

You can also change the default duration at any time with the method ChangeDuration()

attackCooldown.ChangeDuration(8f);

You can also manually deactivate the cooldown and reset its timer to zero.
Use the method Deactivate()

attackCooldown.Deactivate();

A class for handling a cooldown in Unity using a timer.

• Properties

  • IsActive
    Determines if the cooldown is currently active.
    Returns true if the timer is higher than zero.

  • Duration
    Returns the default duration value of the Cooldown object.
    The default duration is set upon initialization.
    It used when you call the Activate() method without inputting parameters.

  • Timer
    Returns the current value from the cooldown's timer

• Methods

  • Activate()
    Activates the cooldown with the default duration.
    You can get the default duration's value form the Duration propertie.

  • Activate(float customDuration)
    Activates the cooldown with a custom duration.

  • Deactivate()
    Deactivates the cooldown manually.
    Resets the timer's value to zero.

  • ChangeDuration(float duration)
    For changing the default duration's value.

• Constructors

  • Cooldown(float duration)
    Used for creating a new cooldown
    Input the default duration of the cooldown

• Events

  • BecameInactive
    An event that is raised when the cooldown becomes inactive
