Show off what you have achieved or been working on, it is very interesting to see what has been implemented regardless of whether you are releasing it or not.

I'll begin this thread with:

That looks really really awesome. Is that login screen animated or is it just a picture?
How did you manage to add that account creation tool? Does it perform HTTP requests or is it directly connecting to your core?

The login screen is a combination of animated models and images. The "Login Screen" button on the bottom right brings up a menu that lets you set the quality level of the login screen. The screenshot shows high. Ultra has many more animated models and adds fog (particle effects use up a lot of processing power in WoW). The lowest quality is 2d (just a image). An old video I have shows this off: https://www.youtube.com/watch?featur...PBPagtYA#t=72s

You cannot perform HTTP requests in WoW, though you can exit WoW and visit a URL.

Essentially I look for where strings are sent to the server and where a value is sent to the client.

On the login screen the only place a variable string is sent to the server is logging in. Username is sent and the password field encrypted is sent.

So what I do is when the "Create Account" button is pressed, I tell the client with a variable that I am now going to be creating an account. This changes the error messages.

The client sends to the server "?username?password?" as the username field (replacing with the relevant details), and random encrypted password. The server listens for a username that begins with "?" then validates and processes the data. It creates the account if all is valid. It will return a different error message (realm is full, you are ban, etc) depending on how far it gets through validation. The variable I flagged earlier will change these error messages client side to different things like, "Username can only contain letters A-Z and numeric values".

As you can only send 50 characters per login (username field) and you cannot login twice at the same time, I send the email field using a different character a few seconds later. A similar method is applied.

It's just problem solving - working with the resources you have.

Client side code:

function CreateAccountFinal(self)
	CreateAccountFrame:Hide();
	local username = AccountNameEditBox:GetText();
	local email = AccountEmailEditBox:GetText();
	local password = AccountPasswordEditBox:GetText();
	local cpassword = AccountPasswordConfirmEditBox:GetText();
	
	if ( password ~= cpassword ) then
		GlueDialog_Show("REALM_TOURNAMENT_WARNING", "Account creation failed.\n\rPasswords do not match.", nil);
		return;
	elseif ( strlen(username) < 3 or strlen(email) < 5 or strlen(password) < 4 or strfind(username, "[^%w]") or strfind(password, "[^%w]") --[[or strfind(email, "[^%w]")]] ) then
		GlueDialog_Show("REALM_TOURNAMENT_WARNING", "Account creation failed.\n\rOnly alphanumerical characters (A-Z, 0-9) allowed!", nil);
		return;
	end
	
	local info = table.concat({"?", username, "?", password, "?"});
	CreateAccountReply = true;

	DefaultServerLogin(info, tostring(math.random(1, 100000)));

	AccountCreateButton:Disable();

	email = string.gsub(email, "%@", "%~")
	info = table.concat({"&", username, "&", email, "&"});
	SAVE_INFO = info
	SAVE_EVENT = true

	AccountEmailEditBox:SetText("");

	if not SAVE_FRAME then
		SAVE_FRAME = CreateFrame("Frame")
		SAVE_FRAME:SetScript("OnUpdate", UpdateAccountEmail)
	end
end

function UpdateAccountEmail(self, elapsed)
	if (SAVE_EVENT) then
		SAVE_TIMER = SAVE_TIMER + elapsed
		if (SAVE_TIMER > 3) then
			SAVE_TIMER = 0
			SAVE_EVENT = false
			if (SAVE_INFO) then
				CreateAccountReply = true;
				DefaultServerLogin(SAVE_INFO, tostring(math.random(1, 100000)));
				AccountCreateButton:Enable();
				SAVE_INFO = nil
			end
		end
	end
end

Server side:

	string AccountName = (char*)&m_challenge.I;
	if (AccountName.substr(0, 1) == "?")
	{
		if (AccountName.find_first_not_of("ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789?") != string::npos)

		string email = AccountName.substr(pass_start, pass_len);

		for (uint8 i = 0; i < email.length(); i++)
		{
			if (email[i] == '~')
			{
				email[i] = '@';
				break;
			}
		}

		m_account = AccountMgr::getSingleton().GetAccount(username);
		if (m_account == 0)
		{
			LOG_ERROR("[AuthChallenge] Account update failed: account does not exist.");
			SendChallengeError(CE_ACCOUNT_IN_USE);
			return;

Haha ok thats a lot of workarounds to get this working. Nice, good job!

Already tried to rep you but I have to spread some rep to others first...
