at top of script:

forward HealthOff(playerid);

we use settimerex instead because we would want to give along the playerid...
so on player spawn we will set the timer:

Код:

SetTimerEx("HealthOff", 900*1000, 1,"i",playerid);

and the public the timer calls, looks good:

Код:

public HealthOff(playerid)
{
	new Float:health;
 	GetPlayerHealth(playerid, health);
 	SetPlayerHealth(playerid, health -5.0);
	return 1;
}

You might want to be able to disable this for a certain player AND per player:

so at top of script:

Код:

new HealthTimer[MAX_PLAYERS]; //we will be saving the timer to an array so we know wich one to disable
forward HealthOff(playerid);

now on player spawn we will set the timer again but with HealthTimer[playerid]:

Код:

HealthTimer[playerid] = SetTimerEx("HealthOff", 900*1000, 1,"i",playerid);

and the public the timer calls, ok:

Код:

public HealthOff(playerid)
{
	new Float:health;
 	GetPlayerHealth(playerid, health);
 	SetPlayerHealth(playerid, health -5.0);
	return 1;
}

now you can disable a timer for a certain player like (if playerid is defined):

Код:

KillTimer(HealthTimer[playerid]);
