At the moment I am learning java and I had now a good idea:

write in a lua script methodes
load this in another lua script
use methodes names as commands

Is that something anybody want to use? Is this possible to implement? What´s your opinion!

My dream is to develope games, which makes fun when I create it and fun when other people play it.

If I understand you correctly, it looks like you want to create global functions for use in your scripts. That's standard stuff and scripters use that technique quite a lot in this community. Simply create a script file with your global commands and then use the require statement to include that file in your scripts for use. For example, if you have a file with global functions called myfunctions.lua then do the following at the top of the script you want to access those functions from:

require "myfunctions"

And be sure to put the myfunctions.lua in the scriptbank folder.

I usually put package.path line in my global.lua and then I can just require "filename" in any lua script file.

Yes, I had a feeling you'd get the error without the package.path command, but I couldn't remember the exact syntax. Thanks, Avram, for providing that.

Well, without detailed analysis, I'd say I see a couple of problems right off.

First, you never defined weapon_name, so you can't access it like an array element with something like weapon_name[e]. You need a global definition somewhere like:



Second, I'm not sure on this one, but I don't think you can call a function like giveback without parens. Maybe that should be giveback()

Other than that, I'd have to try in a real project and see what else I could dig up.

it's already defined in the default global since they updated the weapon.lua script

however it doesnt actually seem to work in anything but the default scripts (for me anyway)

and yes if you put
it should work (if you dont get an error for the name)
