say /spect перевести всех в spectator

ребята вот подскажите можно ли улучшить код и зачем такую фигню выводит ?

[AMXX] Run time error 10: native error (native "cs_get_user_deaths")
[AMXX] Run time error 10: native error (native "cs_set_user_team")

Код:

#include <amxmodx>
#include <amxmisc>
#include <cstrike>


#define PLUGIN "Transfer All In Spect"
#define VERSION "1.0"
#define AUTHOR "SoNeeKK1"


public plugin_init() {
    register_plugin(PLUGIN, VERSION, AUTHOR)
	
	
    register_clcmd("say /spect","go_all_spect")
}
 

public go_all_spect(id)
{
	if(cs_get_user_team(id) == CS_TEAM_SPECTATOR)
	{
		return PLUGIN_HANDLED
	}
	
	for(new i = 1; i <= get_maxplayers(); i++)
	{
		new deaths = cs_get_user_deaths(i)
		user_kill(i, 1)
		cs_set_user_team(i, CS_TEAM_SPECTATOR)
		cs_set_user_deaths(i, deaths)
	}
	
	return PLUGIN_HANDLED
}	

soneekk, потому что проверок нет.
Код:

#include <amxmodx>
#include <cstrike>

#define PLUGIN	"Transfer to Spectator"
#define VERSION	"1.0"
#define AUTHOR	"Stimul"

public plugin_init()
{
	register_plugin(PLUGIN, VERSION, AUTHOR);
	
	register_clcmd("say /spect", "CmdSpect");
}

public CmdSpect(id)
{
	if(cs_get_user_team(id) != CS_TEAM_SPECTATOR)
	{
		new iPlayers[32], iNum;
		get_players(iPlayers, iNum, "a");
		
		for(new i; i < iNum; i++)
		{
			new iDeaths = cs_get_user_deaths(iPlayers[i]);
			
			user_kill(iPlayers[i]);
			cs_set_user_team(iPlayers[i], CS_TEAM_SPECTATOR)
			cs_set_user_deaths(iPlayers[i], iDeaths);
		}
	}
	return PLUGIN_HANDLED;
}

большой спасибо .
