ProtectedString
WARNING: The following tutorial will not work anymore because the String property was locked.
Introduction
A ProtectedString is a data type that imitates the behavior of a string while still being very differrent. This type of string is neither readable or writable from Scripts. Here, I will use the Script's Source property to demonstrate what would happen if you were to attempt to manipulate a ProtectedString.
print( Workspace.Script.Source )
This would print an error saying that Source is not a valid member of Script. This is because the script you are using doesn't recognize Script.Source. It won't recognize any other ProtectedString value either.
There is no way to create a ProtectedString value.
Getting around Script.Source
This is a major obstacle that gets in the way of many scripters all around Roblox. It's the problem of setting a Script's Source. Many scripters will try to set Script.Source the conventional way:
Workspace.Script.Source = [[print("Hello, World!")]]
Unfortunately, this does not work. One way to get around this is to add a StringValue to simulate the Source of the script.
HIERARCHY: Workspace -Script --SourceCode [className = StringValue]
Workspace.Script's source:
script.SourceCode.Changed:connect(function() loadstring( script.SourceCode.Value )() end)
Your script's source:
Workspace.Script.SourceCode.Value = [[print("Hello, World!")]] --> Hello, World!
