* This file is meant to declare various constant data. As you add more *
* custom code to your library, you will be using many constant values *
* used by the game's internal code. Unit types are a good example. *
* Declaring constants allows you to assign a name to these constants *
* which are more convenient to use in your source code. *
* *
* Another advantage is smaller impact in cases where these values would *
* need to change. Rather than revising every single piece of code using *
* this value, you only need to change your constant's value *

# D2Template
D2Template is an open source community project that was developed in order to help modders getting started into advanced code editing on Diablo II. The library provides a basic and simple codebase, ready to be injected in-game, allowing you to quickly inject your own code, without the need to learn stuff like memory patching.
## What does the template include?
To start off, a patcher. This is pretty much the basic of basics, as you need to inject your code into the game at some point, right? You do not need to get into complicated memory patching coding, the template does it for you. Then you have some various utility files, for pointers importing from the game's library, variables declaration, etc.
## What do I need to use this template?
The template was created and compiled with Visual Studio 2012, so it is better if you get Visual Studio 2012 (or just Visual C++ 2012). It is in theory possible to get the template to work with any other IDE but you will not get any support on this from me. Tutorials/Modified templates for other IDE are welcome.
## What should I know before using this template?
First of all, get started with the basics of C/C++. Get used to the syntax, practice by creating basic programs, get at least a basic knowledge of the language. Next, get used with the IDE you're going to use to work with this template. And finally, basic ASM knowledge can also help you a lot.
