Bot Quests for the Bot Creation Limit

zippzipp · #1 02-01-2013, 01:18 PM

Hi guys here is something I implemented on my server it moves the bot creation limit to be optionally controlled by a bot creation quest much like the bot spawn quest.

Add the following to bot.h

Code:

// bot.h 
static uint32 AllowedBotCreates(uint32 botOwnerCharacterID, std::string* errorMessage);

Replace this in bot.cpp:

Code:

// bot.cpp

// REPLACE: 
int32 MaxBotCreate = RuleI(Bots, CreateBotCount);
if(CreatedBotCount(c->CharacterID(), &TempErrorMessage) >= MaxBotCreate) {
	c->Message(0, "You cannot create more than %i bots.", MaxBotCreate);
	return;
}

With this: in bot.cpp

Code:

// WITH THIS:
int createBotCount = CreatedBotCount(c->CharacterID(), &TempErrorMessage);
if(RuleB(Bots, BotCreateQuest)) {
	const int allowedBots = AllowedBotCreates(c->CharacterID(), &TempErrorMessage);

	if(!TempErrorMessage.empty()) {
		c->Message(13, "Database Error: %s", TempErrorMessage.c_str());
		return;
	}

	if(allowedBots == 0) {
		c->Message(0, "You cannot create any bots.");
		return;
	}

	if(createBotCount >= allowedBots) {
		c->Message(0, "You cannot create more than %i bots.", createBotCount);
		return;
	}
} else {
	int32 MaxBotCreate = RuleI(Bots, CreateBotCount);
	if(createBotCount >= MaxBotCreate) {
		c->Message(0, "You cannot create more than %i bots.", MaxBotCreate);
		return;
	}
}

Add this to bots.cpp

Code:

// bots.cpp
uint32 Bot::AllowedBotCreates(uint32 botOwnerCharacterID, std::string* errorMessage) {
	uint32 Result = 0;

	if(botOwnerCharacterID > 0) {
		char ErrBuf[MYSQL_ERRMSG_SIZE];
		char* Query = 0;
		MYSQL_RES* DatasetResult;
		MYSQL_ROW DataRow;

		if(database.RunQuery(Query, MakeAnyLenString(&Query, "SELECT value FROM quest_globals WHERE name='bot_create_limit' and charid=%i", botOwnerCharacterID), ErrBuf, &DatasetResult)) {
			if(mysql_num_rows(DatasetResult) == 1) {
				DataRow = mysql_fetch_row(DatasetResult);
				if(DataRow)
					Result = atoi(DataRow[0]);
			}

			mysql_free_result(DatasetResult);
		}
		else
			*errorMessage = std::string(ErrBuf);

		safe_delete_array(Query);
	}

	return Result;
}

ADD this to ruletypes.h in the #ifdef BOTS section

Code:

// ruletypes.h
RULE_BOOL ( Bots, BotCreateQuest, false)

ADD this to questmgr.h in the #ifdef BOTS section

Code:

// questmgr.h
bool botcreatequest();

ADD this to questmgr.cpp

Code:

// questmgr.cpp

bool QuestManager::botcreatequest()
{
	return RuleB(Bots, BotCreateQuest);
}

ADD this to the QuestManager::createBot function in questmgr.cpp

Code:

// questmgr.cpp
if(RuleB(Bots, BotCreateQuest)){
	MaxBotCreate = Bot::AllowedBotCreates(initiator->CharacterID(), &TempErrorMessage);
}

There you have it. You also need to add a Rule to the db

Code:

INSERT INTO `peqdb`.`rule_values` (`ruleset_id`, `rule_name`, `rule_value`, `notes`) VALUES ('1', 'Bots:BotCreateQuest', 'true', '');

Now bot creation can be controlled on a per character basis with the qglobal bot_create_limit

I'd make a diff/patch using TortoiseSVN. Otherwise you may get a slew of questions and/or complaints that 'this doesn't work' due to those that do not properly apply the changes as you have them written. Just a recommendation of course.

Just a style thing, it would be better to use a reference rather than a pointer for your error message string.
