You would need a 1ms timer, and this is a server performance killer

Apart from this, you could use something like this in HealthUpdate:

Код:

new CurHealth;
GetPlayerHealth(playerid, CurHealth);
if(CurHealth <= OldHealth[playerid] - 40) ...

You also need an array for the OldHealth, else it will be overwritten for each player:

Код:

new Float:OldHealt[MAX_PLAYERS];
public OldHealthCheck(playerid)
{
GetPlayerHealth(playerid,OldHealth[playerid]);
}
