Something like this?
PHP Code:
public MyFunction( )
{
decl iNumber;
iNumber = GetConVarInt( g_hMyConVar );
if( iNumber == -1 )
CreateTimer( 3.0, TimerAdvertisements, -1, TIMER_REPEAT | TIMER_FLAG_NO_MAPCHANGE );
else if( iNumber == 1 )
CreateTimer( 3.0, TimerAdvertisements, -1, TIMER_FLAG_NO_MAPCHANGE );
else if( iNumber > 1 )
CreateTimer( 3.0, TimerAdvertisements, iNumber, TIMER_FLAG_NO_MAPCHANGE );
}
public Action: TimerAdvertisements( Handle: hTimer, any: iNumber )
{
/* My code here */;
if( iNumber > 0 )
CreateTimer( 3.0, TimerAdvertisements, iNumber - 1, TIMER_FLAG_NO_MAPCHANGE );
}
