_G["lavaTouched"] = function (p)
if (not p.Parent:findFirstChild("Humanoid")) then return; end
p.Parent.Humanoid.Health = 0;
end
end);



-- In a different script:
script.Parent.Touched:connect(_G.lavaTouched);

Yes.

We can store it inside a Shared table and then dump the function and load it inside the game.

Example

function Hello()
print("Hello world !")
end

function Run(Function)
loadstring(string.dump(Function))()
end

Run(Hello)

In theory
You could run an entire script inside _G including events etc.

Why would you want to...? If you mean just putting all the code to a game inside 1 script, then you don't need to use _G!

Nick

Why would you like to do that that kind of coding.

You can do this if you would like

Like I already said you can create a function that registers and then dump it.

Like put a Boolean inside the Workspace and then make a script like this

function _G.Toucher()
Game:GetService("Workspace").Brick.Touch:connect(function(toucher)
if Game:GetService("Players"):findFirstChild(toucher.Parent.Name) then
print(toucher.Parent.Name)
end
end)
end

Now we can do

_G.Toucher()

Okay , Assuming I have a function in _G on that starts running from the time the server starts. Could it parse functions for events inside _G ?

Ofcourse you can Nick

function _G.Touch(Toucher)
-- code blah blah
end

Inside this script or a other script you just do a new event.

Game:GetService("Workspace").Part.Touched:connect(_G.Touch)

Okay,
The aim is to get the game:GetService("Workspace").Part.Touched:connect inside _G and running.

^ Like that.

Could
_G.con = game.Workspace.Part.Touched:connect(func)

Then call another function in _G ?
And would that _G.con work normally?

_G is a table.... It is not a Context as you are thinking. IT is a table. You can't run a script in a table, you can only store variables(ints, strings, functions, other tables, environments) inside of _G... But _G is not a context.

You can however set _G as the environment as your script. Not sure why you would though....

@enet

" Not sure why you would though...."

I found that if I assign a variable such as _G.Var = 2 in a script inside studio. That value will remain in _G even if I use the reset (Re-wind button) button. Or delete the script.

@nick... that is not the same for events....

Now then when you save your place and exit studio and reopen it, your _G variables will be erased. They are only kept in the _G environment until you leave studio. So when you publish your game, they won't be included in the publishing.

In addition to ^^^

The only reason it stays in _G is because when you press the rewind button, the _G environment is not cleared. But if you exit studio or join a game it is reset.

Dat feel when you just wasted about 1.5 hours on something redundant.

Thanks for filling me in.
