Hello,

i am here to ask for your help please, as i dont know how to create a cool down timer or should i say i dont know how to link the jump and the cool down timer together.
if anyone could be able to guide me in the right direction that would be amazing.

The cooldown timer is 5 seconds

thank you

Time.deltaTime + or -

Hi Aymane,

first off, Using code tags properly - Unity Engine - Unity Discussions will show you how to use code tags so that we can understand your code.

Cool down timers are simple in concept - if anything you’re overthinking it :slight_smile: Basically, you have two variables - one of them describes how much time should pass before something can happen, and the other describes how much time has passed since the last time that thing happened.

Every call to Update, add your Time.deltaTime to the second variable.

Every time the thing you want to happen is triggered (like when the player presses a jump button) do a simple check - is the time that has passed currently greater than the time that should pass before this thing can happen? If no, don’t do anything. If yes, reset the time that has passed back to zero, and perform whatever action you want to happen.

Here’s some pseudo code that probably explains the concept better:

float actionCooldown = 5.0f;
float timeSinceAction = 0.0f;

void Update()
{
    timeSinceAction += Time.deltaTime;
}

void PlayerPressesActionButton()
{
    if (timeSinceAction > actionCooldown)
    {
        timeSinceAction = 0;
        PerformAction()
    }
}

Note that you don’t really need any kind of logic check outside when the player tries to initiate the action. Good luck getting it all working!
