->

Code:

    new x[16], y[16], z[16], szDesc[32], szData[charsmax(x) + charsmax(y) + charsmax(z) + charsmax(szDesc)];
    
    new Float:vOrigin[32][3], count;
    
    while(!feof(iFile)) 
    {
        fgets(iFile, szData, charsmax(szData));
        trim(szData);
        
        if(!szData[0]) continue;
        
        parse(szData, x, 15, y, 15, z, 15, szDesc, 31);
        
        vOrigin[count][0] = str_to_float(x);
        vOrigin[count][1] = str_to_float(y);
        vOrigin[count][2] = str_to_float(z);

        count++;
        
    }

    for ( new i, rand1, rand2 ; i < 100 ; i++ ) {

        rand1 = random(count);
        rand2 = random(count);

        vOrigin[count][0] = vOrigin[rand2][0];
        vOrigin[count][1] = vOrigin[rand2][1];
        vOrigin[count][2] = vOrigin[rand2][2];

        vOrigin[rand2][0] = vOrigin[rand1][0];
        vOrigin[rand2][1] = vOrigin[rand1][1];
        vOrigin[rand2][2] = vOrigin[rand1][2];

        vOrigin[rand1][0] = vOrigin[count][0];
        vOrigin[rand1][1] = vOrigin[count][1];
        vOrigin[rand1][2] = vOrigin[count][2];
    }
    
    for ( new i ; i < 6 /* or pcvar */ ; i++ )
        spawn_testing(vOrigin[i], szDesc)

or

Code:

    new x[16], y[16], z[16], szDesc[32], szData[charsmax(x) + charsmax(y) + charsmax(z) + charsmax(szDesc)];
    
    new Float:vOrigin[32][3], count;
    
    while(!feof(iFile)) 
    {
        fgets(iFile, szData, charsmax(szData));
        trim(szData);
        
        if(!szData[0]) continue;
        
        parse(szData, x, 15, y, 15, z, 15, szDesc, 31);
        
        vOrigin[count][0] = str_to_float(x);
        vOrigin[count][1] = str_to_float(y);
        vOrigin[count][2] = str_to_float(z);

        count++;
        
    }

    new vOriginUsed;
    
    for ( new i, temp ; i < 6 /* or pcvar */ ; i++ ) {
        do {
            temp = random(count);
        }
        while ( vOriginUsed & temp )

        spawn_testing(vOrigin[temp][i], szDesc)
        vOriginUsed |= temp;
    }

If you want it dynamic and editable by the end user don't forget to check that there are more locations than requested spawns.

Code:

new pcvar = get_pcvar_num(...);
if ( pcvar > count )
    pcvar = count;
//...

thank you @BLACK ROSE , i will test it
