However can there be 32*32 numbers in boolean array, and in integer? I mean can it be something like this:

{1,2,3...32}
{34,35,36...64}
...
{31*32,31*32+1,31*32+2...32*32}

=O

Also how does array work in general? And how do I check value of array? And what if I want to just change value of 5th line 3rd place number? How do I do that?

Each integer holds 8 times as many on/offs as a boolean. You can have an array of them in the same way as you can have an array of booleans if you want many values - the difference being that you have to first figure out which element to grab from the integer array, then figure out the specific bit inside of that number. It's the usual speed/storage trade-off. Something like the following, off the top of my head.

[pascal][background=#FFFFFF][comment=#0000FF][normal=#000000]
[number=#C00000][reserved=#000000][string=#00C000]var
MyArray: array[0..9] of Integer; // 320 bits

function GetBit(WhichBit: Integer): Boolean;
begin
// get whatever bit - e.g. bit number 36, in array
Result := MyArray[whichBit shr 5] and (1 shl (WhichBit and 31)) <> 0;
end;

procedure SetBit(WhichBit: Integer);
begin
MyArray[whichBit shr 5] := MyArray[whichBit shr 5] or (1 shl (WhichBit and 31));
end;

procedure ClearBit(WhichBit: Integer);
begin
MyArray[whichBit shr 5] := MyArray[whichBit shr 5] and not (1 shl (WhichBit and 31));
end;[/pascal]

Meh. Totally untested and I don't suppose you really want stuff like that though. Seriously, use TBits - a class exists for this purpose, so there's no reason to reinvent the wheel.

[EDIT: looks like my code breaks the Pascal tags! BlueCat, you have work to do ]

[BlueCat Edit :twisted: The perfect opportunity to test my new evil colouring tags, heehee. Edit them if ya don't like 'em]

[EDIT 2: I guess it's time to fix the above code ]

Who says I don't like 'em? After all, you're talking to the person whose desktop wallpaper looks like this:

Hi, I just started working on Hartland, an MMORPG, I want it to have a Game it self, Level Editor, Messenger, and a few other things. Howevere I have no idea where to start. I am no begginer in programing, or maybe I am.
Right now I was thinking about creating engine, basically by that I mean Player walks around, levels are actually drawn with help of level files, and tha's it. Howevere I ahve no idea where to start, or how. Help?

I think I can help you out with lots of what you need. I have seen both the source code and the server files for a commercial Delphi MMORPG. (The Legend of Mir), it's a very addictive game and having seen the server files, it opened up a lot of ideas on how to get round problems that bothered me in the past. I started coding my own MMORPG about 2 weeks ago and have a Message Server, Login Server, Main Server, Client Shell, Image Compressor, Image Library Builder, and have just started the Map Editor. The biggest problem I am having is getting a TRichEdit working with fullscreen DirectX, infact it looks like I will have to bin it an write a new dx component. The messaging functionallity is complete though and it seems fairly stable. I am using Indy components for the TCP/IP.

Go Terranigma! Good work Ali

Anyway, there are quite a few MMORPG's being made in Delphi.. Though not alot get finished (Bah! to programmers apathy).. I would like to see a few more MMORPG's be made.. Hopefully free .. But hey, i dont program in Delphi much more.. (C++ :roll: ).. But Delphi is pretty fun (when you dont have to use many components [im not a fan of drag'n'drop programming]).

But i wish you all the best, and that the MMORPG's become a sucess (DIE GRAAL!).
