[JASS] What's LUA? I don't know it?

[ALTELMA]

I see many guys mention to it in Jass script forums and other tutorials. I don't know what's it? and Do anything?

Grimoire allows you to run other codes in the editor. Here is a good lua tutorial->http://www.lua.org/manual/5.1/.

Lua is mostly used for creating object data and setting variables but it has a few other uses too probably.

This is LUA in warcraft...

Yes, it is used primarily for object generation. However, that generation can only be run on the map's compilation, not in-game. (sadly)

It can save some people time on making objects (like if you want to mass-create an object with different values), or if you want to make a system more portable. (you can have anyone copy and paste the script into their map, and it will generate the objects for them)

The only problem is it is a bit limited. You can set object fields but you cannot read them. For greater flexibility, there are things such as GMSI (found on wc3c.net). The good thing about Lua, however, is that one only needs to download Jass NewGen to use it. (IMO, Jass NewGen should include GMSI)

Well, you can use the Lua framework to write JASS code in order to read those object fields ; ). That's how object ids are ported into global constants in LUA_GET_OBJECT_ID.


You can also use Lua for JASS frameworks. For example, one thing I'm thinking of doing is running a lot of my save/load stuff on Lua rather than having a huge template : ).

Ahh Thanks all guys.
