HILFE

if(!strcmp(tmp, "pd",true,4))
{
if(gTeam[playerid] == 2 || IsACop(playerid))
{

GetPlayerPos( playerid, Positions[0][0], Positions[0][1], Positions[0][2]);
GetObjectPos(lspdgate, Positions[1][0], Positions[1][1], Positions[1][2]);
if(GetDistance( Positions[0][0], Positions[0][1], Positions[0][2], Positions[1][0], Positions[1][1], Positions[1][2]) < 30.0 )
{
GetPlayerName(playerid, sendername, sizeof(sendername));
format(string,sizeof(string), "* %s öffnet das LSPD Tor.", sendername);
ProxDetector(30.0, playerid, string, COLOR_PURPLE,COLOR_PURPLE,COLOR_PURPLE,COLOR_PURPLE,COLOR_PURPLE);
MoveObject(lspdgate, 1588.5617, -1638.0871, 5.7200, 1);
}
}
return 1;
}

/---------------------------<[ OnPlayerCommandText ]>--------------------------------------------------------

public OnPlayerCommandText(playerid, cmdtext

if(strcmp(cmd, "/menu", true) == 0)
{
if(IsPlayerConnected(playerid))
{
new Float:health;
if(PlayerToPoint(15,playerid,370.360534,-6.758678,1001.858886))//Cluckin' Bell
{
new x_nr[256];
x_nr = strtok(cmdtext, idx);
if(!strlen(x_nr))
{
SendClientMessage(playerid, COLOR_GREEN, "|_____________ Cluckin' Bell Menu ______________|");
SendClientMessage(playerid, COLOR_WHITE, "USAGE: /menu [item number]");
SendClientMessage(playerid, COLOR_YELLOW, "[1]Water:($1), [2]Sprunk:($1)");
SendClientMessage(playerid, COLOR_YELLOW, "[3]'lil Clucker:($2), [4]Bucket o' Chicken:($5),");
SendClientMessage(playerid, COLOR_YELLOW, "[5]Chicken Nuggets:($2), [6]Chicken Sandwich:($4),");
SendClientMessage(playerid, COLOR_YELLOW, "[7]Chicken Salad:($3)");
SendClientMessage(playerid, COLOR_YELLOW2, "Straight from the factories: Taste the Cock!");
return 1;

if(!strcmp(tmp, "pd",true,4)) was bedeutet die 4 am schluss?
