[a-day]

a friend has made me this code but it dosnt work so how it needs :/ i dosnt understand it

Код:

#include <a_samp>
forward Count(playerid);
new counter[MAX_PLAYERS];
new cnt[MAX_PLAYERS];
public OnFilterScriptInit()
{
	print("\n--------------------------------------");
	print(" Blank Filterscript by your name here");
	print("--------------------------------------\n");
	return 1;
}



public OnPlayerCommandText(playerid, cmdtext[])
{
	if (strcmp("/count", cmdtext, true, 10) == 0)
	{

	cnt[playerid] = SetTimerEx("Count",1000,1,"i",playerid);
	return 1;
	}
	return 0;
}
forward PlayerToPoint(Float:radi, playerid, Float:xs, Float:ys, Float:zs);
public PlayerToPoint(Float:radi, playerid, Float:xs, Float:ys, Float:zs)
{
  if(IsPlayerConnected(playerid))
	{
		new Float:oldposx, Float:oldposy, Float:oldposz;
		new Float:tempposx, Float:tempposy, Float:tempposz;
		GetPlayerPos(playerid, oldposx, oldposy, oldposz);
		tempposx = (oldposx -xs);
		tempposy = (oldposy -ys);
		tempposz = (oldposz -zs);
		if (((tempposx < radi) && (tempposx > -radi)) && ((tempposy < radi) && (tempposy > -radi)) && ((tempposz < radi) && (tempposz > -radi)))
		{
			return 1;
		}
	}
	return 0;
}
stock GameTextForNearPlayers(playerid,Text[],time,Style)
{
new Float:pos[3];
GetPlayerPos(playerid,pos[0],pos[1],pos[2]);
for(new i = 0;i<MAX_PLAYERS;i++){
if(IsPlayerConnected(i)){
if(PlayerToPoint(4.0,playerid,pos[0],pos[1],pos[2]))GameTextForPlayer(i,Text,time,Style);}}
return 1;
}
public Count(playerid)
{
switch(counter[playerid])
{
case 0:GameTextForNearPlayers(playerid,"~w~0",1000, 3);
case 1:GameTextForNearPlayers(playerid,"~w~1",1000, 3);
case 2:GameTextForNearPlayers(playerid,"~w~2",1000, 3);
case 3:GameTextForNearPlayers(playerid,"~w~3",1000, 3);
case 4:GameTextForNearPlayers(playerid,"~w~4",1000, 3);
case 5:{GameTextForNearPlayers(playerid,"~w~5",1000, 3);counter[playerid]= 0;KillTimer(cnt[playerid]);}
}
counter[playerid]++;
return 1;
}
