 ===Global Functions===
-Have you ever wondered how things like :Remove() and :Clone() always work, even though you've never indexed it? Here's how:
+Have you ever wondered how functions like wait() always work, even though you've never indexed them?
-If you know how to use the _G[] (global) command, this might come more easily to you than others. This is basically how a global command works:
+You can, with _G.
-_G["Bob"] = game.Workspace.Bob
+Script 1:
+<pre>_G.Player = game.Workspace.Player</pre>
+Script 2:
+<pre>_G.Player:remove()</pre>
-If you're in a ScriptBuilder, you can exit that script and open a new one. Put this in it:
+If you are familiar with pure Lua, you should notice that we have to index _G before the variable name. Scripts will error without it, because of  security vulnerabilities.
-Bob.Torso:Remove()
+You can used shared instead of _G, if you want.
-run that script, and your torso gets removed! Why? Because the _G[] (global) command makes "Bob" availible in every script. Now, to get a global function:
-_G["Lazer"] = function(person) person.Torso:Remove() end
-Now exit that, and do this:
-Lazer(game.Workspace.Bob)
-If your character's name is, "Bob," you should have your torso removed.
