PHP Code:


public void OnPluginStart()
{
    HookEvent("player_spawn", Event_PlayerSpawn);
}

public void Event_PlayerSpawn(Event event, const char[] name, bool dontBroadcast)
{
    int client = GetClientOfUserId(event.GetInt("userid"));
    
    if (client)
    {
        if (CheckCommandAccess(client, "", ADMFLAG_RESERVATION, true))
        {
            RemoveClientGrenades(client);
        }
    }
}

void RemoveClientGrenades(int client)
{
    int ent = -1;
    
    while ((ent = GetPlayerWeaponSlot(client, CS_SLOT_GRENADE)) != -1)
    {
        RemovePlayerItem(client, ent);
        RemoveEntity(ent);
    }
} 


Use the new syntax.
round_end it's a general thing, it's not like player_death, player_spawn, player_hurt etc, so it doesn't have "userid" param.
