[solved] Simple timer/alarm

Hi. It's me again pfft

I have a very simple alarm that counts down and once it hits 0 it executes a piece of code. The problem is that I don't really know what value to substract from it on update(), so that it measures actual time.

Hi there,

Create a member variable of type flt (float) and set it to a value that is the length of your timer before the alarm goes off.

Then, in the update function do value -= Time.d();

When value <= 0, execute your stuff.

Hope that helps!

Well, that's exactly what I have at the moment, but if I want it to count for example 1 second, what value should I set?

Edit: Now that I've read my first post again I think I might have been imprecise. My timer works fine - I just don't know how to set it to count actual seconds/milliseconds wink

Time.time()? i believe that's what youre looking for

Hey Azriel the Time.d() is actually the time it took in seconds for the engine to process the last frame. That number is usually quite small something like 1/60 sec or 0.017 sec if your fps are at 60 fps.

So for example to measure 5 seconds you can do something like:

Code:

flt myTimer = 0.0f;

bool Update()

{

   myTimer += Time.d();

   if(myTimer >= 5.0f)

   {

   ...

   }

   if(Kb.bp(KB_ESC))return false;

   return true;

}

Can't check the project atm, cause I'm at home already, but as far as I know that's how I did it and it didn't work as supposed. I'll double check my code tomorrow, probably some silly mistake, cause I've just made a new timer here and everything's fine.
Speaking about timing - is Time.d() what I should use in my whole game to get timing right? I've seen there were a couple other delta counters.

well you can check Time fonctions,

Flt d ()C {return _d ;} // game time delta (frame time duration, modified by game 'speed', affected by 'smooth' 'skipUpdate' and application pauses)

Flt time ()C {return _t ;} // game time in current frame ( seconds since application started, modified by game 'speed', affected by 'smooth' 'skipUpdate' and application pauses)

dont forget to use flt not int

Ok, I had a little mistake in my code and that's why the timer was innacurate wink
