Read from file - [XST]O_x - 15.05.2010

Hello.
Listen guys i tried to make two commands that allows you to save your position by using /s and then load it by using /l.
Here is what I've done:

pawn Код:

if(strcmp(cmdtext, "/s", true) == 0)
    {
      new File:Pos=fopen("Pos.txt",io_write);
      new Float:x, Float:y, Float:z;
      new string[256];
      GetPlayerPos(playerid,x,y,z);
        format(string,256,"%f,%f,%f",x,y,z);
        fwrite(Pos, string);
        fclose(Pos);
        return 1;
    }

And the /l :

pawn Код:

if(strcmp(cmdtext, "/l", true) == 0)
    {
        new File:Pos=fopen("Pos.txt",io_read);
        new string[256];
      SetPlayerPos(playerid,x,y,z);
      fread(Pos,string);
      fclose(Pos);
        return 1;
    }

I know the /l is totally messed up and it's not working >:
But the /s is working,it creates a file with the positions in it, i just don't know how to read it.
Anyone help please?
Thanks in advance.

This will work if you have only written one line to the file.

pawn Код:

if(!strcmp(cmdtext,"/l",true))
{
    new
        File:Pos=fopen("Pos.txt",io_read),pos[2],
        string[256],holder[128],Float:x,Float:y,Float:z;

    fread(Pos,string);

    pos[0] = strfind(string,",");
    pos[1] = strfind(string,",",true,pos[0]+1);

    strmid(holder,string,0,pos[0]);
    x = floatstr(holder);

    strmid(holder,string,pos[0]+1,pos[1]);
    y = floatstr(holder);

    strmid(holder,string,pos[1]+1,strlen(string));
    z = floatstr(holder);

    SetPlayerPos(playerid,x,y,z);
    fclose(Pos);
    return 1;
}

It's a bit more complicated then the one you posted. :P

HOLY MAMA,back to the wiki

anyway thx

Oh and btw,i have another question.
Is there any way to make /l work only if /s was already typed?
I mean like if you type /l before /s it will send a message "Save a position first." or smth?
thx

Sort of. It's just a trial and error sort of thing. I made a file with some coordinates in it and kept editing and running this script until it showed the right thing.

Easier way Warning: untested

pawn Код:

new Float:PlayerPos[MAX_PLAYERS][6];
new Float:TeleportDest[MAX_PLAYERS][3];
new Float:TelePos[MAX_PLAYERS][6];


    if(strcmp(cmd, "/s", true) == 0)
    {
      if(IsPlayerConnected(playerid))
            {
                GetPlayerPos(playerid, TeleportDest[playerid][0],TeleportDest[playerid][1],TeleportDest[playerid][2]);
                SendClientMessage(playerid, COLOR_GRAD1, "Position set use /l to load it");
        return 1;
    }

    if(strcmp(cmd, "/l", true) == 0)
    {
      if(IsPlayerConnected(playerid))
            {
                if (GetPlayerState(playerid) == 2)
                {
                    new tmpcar = GetPlayerVehicleID(playerid);
                    SetVehiclePos(tmpcar, TeleportDest[playerid][0],TeleportDest[playerid][1],TeleportDest[playerid][2]);
                    TelePos[playerid][0] = 0.0;TelePos[playerid][1] = 0.0;
                }
                else
                {
                    SetPlayerPos(playerid, TeleportDest[playerid][0],TeleportDest[playerid][1],TeleportDest[playerid][2]);
                }
                SetPlayerInterior(playerid,0);
                SetPlayerVirtualWorld(playerid,0);
