You have to set the timer on repeat on a smaller relevant interval.

And a new variable to count the number of times the timer is being called, as to record the countdown.

pawn Код:

// new variable
new HTimerCount;

// when declaring timer
HTimerCount = 1;
HTimer[WANG] = SetTimerEx("wangbomb",1000,true,"i",playerid);

SO your "wangbomb" have to be modified with a count check:
(when to destroy timer and stuff)

pawn Код:

if (HTimerCount == 12) //12 seconds
{
}

How to update progress bar:

pawn Код:

else
{
}

And you also need to increase the variable count "HTimerCount": (this goes outside of the if-else)

pawn Код:

HTimerCount++;
