Count Down Timer help

Unity Engine
1

Hi everyone,

I would liek to create a count down time. Lets say its start counting down from 2 and when it gets to 0 it sets a boolean to false.

I am having a little problem developing the logic. I thought it would have been so easy.

I always want the timer count down to start from 2 and reset to 0 where it will start from 2 again when I press “down”. However it doesnt happen.

Where did I go wrong?

My code is below.

public float keyTime = 2;
public float guiTime;

public bool canUseKey = false;

void Update()
{
if (Input.GetKeyDown("down")) 
{
      canUseKey = true;

}


if(canUseKey  == true)
{
    keyTime -= Time.deltaTime;
    if(keyTime  <=0)
    {
       canUseKey = false;
       keyTime  = 2;
    }

}

}

set it to 2 when you get a key down

Set what to 2?

You could use this lib (a Timer class). Usage:

int _count = 5;
void Start() {
    Timer t = new Timer(1, 5); // tick each second, five times
    t.Tick += delegate { _count--; Debug.Log("Timer tick: " + _count); };
    t.Complete += delegate { Debug.Log("Timer complete. Now showing the 'Play again' button..."); };
    t.Start();
}

Another timer example here.

set keytime to 2.

I am getting a couple parsing errors with this.

This surprisingly works.

Please, drop the eDriven.Core.dll into the project before trying the example :wink:
