how can I make all players invisible when they spawn?
I want to insert invisibility script in this IF

#include <sourcemod>
#include <sdktools>
public OnPluginStart()
{
HookEvent("player_spawn", Event_playerS);
}
public Event_playerS(Event hEvent, const char[] sEvName, bool bDontBroadcast)
{
int iUserID = hEvent.GetInt("userid");
int iClient = GetClientOfUserId(iUserID);
if(iClient)
{
GivePlayerItem(iClient, "weapon_hegrenade");
SetEntityHealth(iClient, 1);
[code here]
}
}
