/[release]C++ code peices

[Reimniess]

well while working on my mmo in C++ I had made up some classes and functions I figured maybe somone could use

some of it is new functions and some is off the top of my head so no garentee's

and yes I made them


first off is my own improvision of the rand function that allows you to set the max return please note it is advised you start use the line


srand((unsigned)time(0)); befor useing it or will be prone to patterns and that is not good

#include "stdafx.h"
#include <iostream>
#include <cstdlib> 
#include <ctime> 

using namespace std;

int rand2(int div)
{
	int a = rand();
	long int round = 0;
	int rhold = RAND_MAX / div;
	for(;;)
	{
		if(a > rhold * round && a < rhold * (round+1))
		{
			return round+1;
		}
		else
		{
			round++;
		}

	}
}

next off is my refrence file reader
each file is a list of either int or multi char seperated by ','
please note you need a , at the very end


declare a memory type
example:

memory test;

then you call load
example:

test.load("test", 3, false);

this will load the name in the first arguement as <name>.ref where it till look for it in a data folder in the folder it is in

second one is the number of ID's you want it to load

third is true or false put false only if they are all numbers or will crash


to call char arrays call for <memory name>.id[<number of the one you want to load>]

to call a in <memory name>.gint[<number of the one you want to load>]

Removed Until made a little more user freindly 

side note: some of your comments actualy caused me to look back at the code and though of yet an even better method of doing this

the memory is good for use on single lists or entire groups of lists by use of multiple classes


I was useing them to read refrence files for monster stats / names for my server files as well as attributes of most things in them and so far it works fast and accuratley without error as long as you make no error in it's use


if you can use it good for you if not oh well please don't spam and I plan to release more later just these are all I had on hand at the moment I could remember exacty how worked




also these are my original works just to restate that for skimmers <_<;

May we give suggestions?
Read this for a better implementation of rand(): http://www.eternallyconfuzzled.com/a..._art_rand.aspx

Instead of int gint[999]; you could use the stl vector(http://www.cplusplus.com/reference/stl/vector/) so you wont waste the unused memory.
Instead of passing "void load(char list[99]", you should pass a pointer to const char, so it wont need to copy the string, you can also use std::string(http://www.cplusplus.com/reference/string/string/) instead of char array.
You should also use variables as private and create a get method that will check if that value exists to avoid problems.

Other then that it seems good :P

well they are what they are for a reason of them having other perposes in the program they were made for but if somone wants to modify it to those that is fine

How bout you take the goddamn criticism and use it to assist further works?

I do appreciate critisizm but what he brought up I put like they are on perpose

[GlaphanKing]

Since we are developers we will give criticism that is either end of the spectrum. Take it or leave it.

I'm sure you wrote these without doing some heavy researching.

If you plan on rewriting code that is already there, it is a good first attempt. I don't know the level of your coding but I do believe you should use the libraries already provided and accessible when using c++. Hundreds of libraries, like Allegro, boost, DirectX, .NET are there for a reason. They have taken the time to perfect the methods and functions.

As for the memory writer. It has potential to be something. However, when messing with memory it is good practice to research a lot of stuff, like call stacks, buffer and buffer overflow, pointers and threading.

C++ has the potential to manipulate memory in such a way that you can crash your system and overflow the stack so bad you will need to reformat. Personal quote from myself. Happened to me.


But tell me? What is the purpose of these classes? are they for developing servers or just for anything?

Well, sorry then, its cause I never saw anyone wanting to waste memory and other things, but if it was on purpose ok I guess.

Next time I wait for you to answer the "May we give suggestions?".

yes you may and I had remembered I had not updated that ptograms function so yes indead it has some downfalls in it I would update it but in truth looking back at even the fully functional code I though of a way to prevent stack overflows so I;d rather get that done and out rather then release code that could cause problems to those who dont look at the code they use
