here's the undefined symbol line:

Код:

new Float:Dist = GetDistanceBetweenPoints(pos1X,pos1Y,pos1Z,pos2X,pos2Y,pos2Z);

Here's the warning:

Код:

(2985) : warning 202: number of arguments does not match definition

and heres line 2985:

Код:

id = GetClosestPlayer(playerid)

here's getclosestplayer:

Код:

stock GetClosestPlayer(playerid,Float:limit)
{
	new Float:x1, Float:y1, Float:z1, Float:x2, Float:y2, Float:z2;
	GetPlayerPos(playerid,x1,y1,z1);
	new Float:Range = 3.0;
	new id = -1;
	foreach(Player,i)
	{
		if(playerid != i)
		{
			GetPlayerPos(i,x2,y2,z2);
			new Float:Dist = GetDistanceBetweenPoints(pos1X,pos1Y,pos1Z,pos2X,pos2Y,pos2Z);
			if(floatcmp(Range,Dist) == 1 && floatcmp(limit,Range) == 1)
			{
				Range = Dist;
				id = i;
			}
		}
	}
	return id;
}

PHP код:

Float:GetDistanceBetweenPoints(Float:pos1X, Float:pos1Y, Float:pos1Z, Float:pos2X, Float:pos2Y, Float:pos2Z)
{
    return floatadd(floatadd(floatsqroot(floatpower(floatsub(pos1X, pos2X), 2)), floatsqroot(floatpower(floatsub(pos1Y, pos2Y), 2))), floatsqroot(floatpower(floatsub(pos1Z, pos2Z), 2)));
}
stock GetClosestPlayer(playerid,Float:limit)
{
    new Float:x1, Float:y1, Float:z1, Float:x2, Float:y2, Float:z2;
    GetPlayerPos(playerid,x1,y1,z1);
    new Float:Range = 3.0;
    new id = -1;
    foreach(Player,i)
    {
        if(playerid != i)
        {
            GetPlayerPos(i,x2,y2,z2);
            new Float:Dist = GetDistanceBetweenPoints(x1,y1,z1,x2,y2,z2); //Those variables weren't defined as what you had, so they were replaced with the original ones.
            if(floatcmp(Range,Dist) == 1 && floatcmp(limit,Range) == 1)
            {
                Range = Dist;
                id = i;
            }
        }
    }
    return id;
}
CMD:getclosestplayer(playerid, params[]){
    new
        id = GetClosestPlayer(playerid,15.0);//You were missing the radius parameter.
        
    if(!IsPlayerConnected(id)) return SendClientMessage(playerid,-1,"That player isn't connected.");
    else{
    
        new
            str[64],pname[MAX_PLAYER_NAME];
            
        GetPlayerName(id, pname, sizeof(pname));
        format(str, sizeof(str), "%s is the closest player to you.", pname);
        SendClientMessage(playerid, -1, str);
    }
    return 1;
} 


The variables in the GetClosestPlayer function were incorrect as well as you didn't specify a radius for the function to use during calculation.
