Environment and Global variables

[Bonsai]

Hey,

I have a problem with loading script files of maps into an environment.

If a map uses "addEventHandler" to e.g. add the event "onClientMarkerHit" it most likely uses the "source" variable inside the attached function.

However, this source variable does not exist in the scripts environment.

The only way to still make it work at the moment is to let it have access to the _G environment, where the variable seems to exist.

Is there a way to make it work without that?

Sorry for double post, I can't edit my original post somehow.

I meanwhile tried something, which seem to work, but I would appreciate if anyone can confirm that to be a solid solution for the problem.

Basically, I modify the metatable of _G and redirect all changes there into my newly created environment.

Maybe you can create a environment metatable with __index = _G

Here a little example: https://github.com/multitheftauto/mtasa-resources/blob/master/[editor]/edf/scriptreader_client.lua

It seems to be more secure for me.
