error C2440: '=' : cannot convert from 'char' to 'char [20]'

been working at this all night anyone got any solutions for me? much appreciated.

this is in command.cpp

Code: Show/Hide

      if (c->check("reg"))
      {
         p->name = playerName[regNum];
         regNum++;
         sendPrivate(p, "You have been registerd to play this session.");
      }

what i don't understand is why are you trying to change p->name, from what i can see it looks like you're trying to make an array'd list of people who reg for a game.

if that is what you're trying to do, try changing

Code: Show/Hide

p->name = playerName[regNum];

Code: Show/Hide

playerName[regNum] = p->name;

indeed, p->name is an char[20] array type which cant be initialized in such a way.
however you can change the value of playerName[#] (# is regNum in this case).

so what myke sais is an option.

Which is why you should actually learn C++ before trying to make bots.

Ah crap... i didn't even notice it... was so tired last night... ahahahaha, im so stupid for that. Thanks for pointing that out for me

And btw i haven't done a course but i spent a few weeks reading "C++ - How To Program, 5th Edition (2005)" so i do have some knowledge.. just didn't realize that i was trying to put an array into a pointer..

I spent my time reading books and tutorials instead of actually trying to program something, and I regret that, because I still don't know how to program. But I learned 90% of what I know through attempts, not the books I read.

i learned everything i know now by looking at other sources.
I did read a book from the liberary when i started coding but i stoped at chapter 4 of 17, which just where some basics (!, ==, ++, --, -=, +=, %, /, {} etc... not even array and pointers which where chapter 5).
so i had to learn practicly everything from scratch (was a bitch tho).

Well, I'm sorry reading didn't work out too well for you guys, but I definitely got my basic C++ knowledge from the tutorial I link all over the place here. Obviously coding is what makes you really understand the stuff, but if you don't get the basics (pointers, etc.) and then come running to a forum when you get a compile error, you're going about it the wrong way.

Ok, since my code that ive tried hasn't worked, and i looked up usign a reinterpret_cast, and my attempt is this..

Code: Show/Hide

      if (c->check("reg"))
      {
         playerName[regNum] = reinterpret_cast <char> (p->name);
         sendPrivate(p, &playerName[regNum]);
         sendPrivate(p, "You have been registerd to play this session.");
         regNum++;
      }

But when i try to call a name from the array it comes out in
"Ã…ÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃ"

Any ideas on this?

Read a stupid tutorial. You're copying a char, not a char array (string).

Character sequences

you don't have to be so rude.

try this:

Code: Show/Hide

strcpy(playerName, p->name);

I already suggested it two times, but I'm sorry for being rude.
