Explanation of what is what in /LuaRules ?

[SeanHeron]

Hey, I've stumbled into this problem more than once now, and the best I can find for explanation is here.

I'm not exactly a wiz at Lua, but I might still want to make use of some Gadgets that are out there (eg unit_morph.lua)- however it's not clear to me which *.lua files I'll be needing in my LuaRules folder.

You need to have a main.lua, that much is obvious (and stated in this thread).
But what about the others ? jK states (in the thread linked above - talking about LuaGaia, but I suspect the same applies for LuaRules) that:

you have to setup the gadgetHandler enviroment:
* copy main.lua,draw.lua,gadgets.lua etc. (or link the basecontent ones)

This (pasting a set of files in from a different game) is what worked for the problem described here. I'm less clear, though, on the alternative offered, linking the basecontent ones - I think this means more than just setting up springcontent.sdz as a dependency, right ?

Thanks for any explanations and answers!

Read engine source code for full reference.

In short: for LuaRules the engine looks for a main.lua and draw.lua. Nothing more. But most mods implement a gadget handler in these files that allows to load more files from this point.
Look for includes in the files to see which files are referenced.

If you want to use the gadget handler provided with spring you have main.lua and draw.lua just have a single line in them, that includes the spring version. Many games do this.
