i was looking to write a dll for mervbot.
just a simple staff list from staff.txt...

void botInfo::gotCommand(Player *p, Command *c)
...
case OP_Player:
   {
      if (c->check("staff"))
      {
sendPrivate(p, "start");
char line [256];
ifstream staff;
staff.open("staff.txt");
if (!staff)
{
sendPrivate(p, "Error loading staff.txt");
}
staff>>line;
while (!EOF)
{
sendPrivate(p, line);
staff>>line;
sendPrivate(p, "loop");
}
staff.close();
sendPrivate(p, "end");
      }

i added start, loop, and end for debugging.
so it compiles and loads, but only pms you start and end.
which means its completely ignoring my loop.

also, when i remove staff.txt, theres no error.
which means its ignoring my error too.

what am i missing?

try

Code: Show/Hide

while (!staff.eof())

if you remove staff.txt it doesn't crash? try making the condition if (!staff.good()) and put the rest of the crap in an else block

for some reason, those dont work =S
mine dont either...

also,
why can i use sendPrivate(p, "loop");
with "loop" and not a string?
using char ignores whitespace in my file...

----

so all that was too complicated and didnt work.
i tried this, and it worked.

Code: Show/Hide

case OP_Player:
   {
      if (c->check("about"))
      {
         sendPrivate(p, "I display the staff list.");
      }
      if (c->check("version"))
      {
         sendPrivate(p, "staff.dll by Cheese");
      }
      if (c->check("staff"))
      {
ifstream staff;
staff.open("staff.txt");
      char line [256];
      while (staff.getline(line, 256))
      {
         sendPrivate(p, line);
}
      staff.close();
}
   }

however,

Code: Show/Hide

if (staff.bad())
{
sendPrivate(p, "Staff.txt is missing");
}

didnt.
renaming or deleting the file didnt make anything happen.
i tried staff.bad(), !staff.good(), !staff.exist(), and !staff.
nothing at all

What about staff.is_open() ?

sendPrivate needs a String, which is one of catid's classes and not built-in. If you look in mervbot source you'll see theres a constructor that takes in a const char* so it can cast it implicitly.

If you want to use a string, try

sendPrivate(p,(String)stringVar.c_str());
