	It is very important for Wesnoth to have a way of scripting AI without modifying the c++ source code. Some time ago, it was possible to use Python to code AIs, but it was removed due to security issues. Now, we're adding Lua as a new way to script AI. The core capabilities were already added, but we need to integrate Lua AI scripts better.		It is very important for Wesnoth to have a way of scripting AI without modifying the c++ source code. Some time ago, it was possible to use Python to code AIs, but it was removed due to security issues. Now, we're adding Lua as a new way to script AI. The core capabilities were already added, but we need to integrate Lua AI scripts better.

	Wesnoth AI consists of different components. each component is a c++ object, which provides an interface to allow the ai to delegate part of the turn sequence to that c++ object. but, that c++ object can be a proxy for code written in different language, such as formula_ai or lua. So, we have a lua engine - a c++ class which is responsible with creating c++ proxies for lua code snippets. this lua engine must provide access to all the information that the c++ AI knows - caches like 'attacks' and 'possible moves', values of aspects such as 'aggression' and 'caution', etc. So, there's a large number of AI support functions which we need to expose to lua code.

	To quote from Alpha Centauri, "Technological advance is an inherently iterative process. One does not simply take sand from the beach and produce a Dataprobe. We use crude tools to fashion better tools, and then our better tools to fashion more precise tools, and so on. Each minor refinement is a step in the process, and all of the steps must be taken. ".

	We want to make it easy to write Lua AI. the best way to ensure that is to try to write some AI components, and see what's easy, what's hard, and what's missing. So, here are a few things that can be done to get you started and to allow to code some useful lua/c++ code which can be included in wesnoth lua ai standard library.
