Roblox doesn’t let you add EnumItem attributes manually in the properties window (yet), only by scripting. I fixed that.
Recently I came across this thread, as I came across the lack of an EnumItem attribute type option in the Add Attribute menu. I was able to add an EnumItem attribute via script, and figured I’d share that, as well as my own suggestion of adding a dropdown for EnumItem or something similar. Roblox said it’s difficult to achieve in a user-friendly way with the current amount of enum types exceeding 100, and by a good bit.
I made a reply with a simple function to detect attribute changes and identify Enum’s from string-type attributes. I noted an assumption that it could be used in plugin form. So, that’s what I made.
You can get the plugin here, or click on the title of this thread. This plugin is honestly really simple, and I personally don’t think it’d impact performance–but I haven’t tested it on an experience with a lot of instances. Do let me know if it is negatively impactful to Studio or gameplay and I will fix the issue or remove the plugin until a more suitable method is achieved or is implemented by Roblox themselves.
Use / to retain the string attribute type when setting an enum. i.e /Enum.KeyCode.One
Credit to @Spacerator for this idea!
Showcase — Usage upon install:
To retain string type attributes and store a full enum:
View the new popup widget and select any EnumType with ease:
This list is designed to update automatically using Roblox’s :GetEnums() and :GetEnumItems() methods. For cases in which new Enum types & values are added to or removed from Roblox.
Attributes > Add Attribute > String Type > /Enums (in the value text box)
This is about as far as I can go with this. I’d suggested it to Roblox in my last reply in the linked thread above, that’d be the next best step for this type of thing. My only final want for this is to have the ability to double click the enum that’s replaced the original string and revert back to a string box (unless an EnumItem attribute type is added that functions similarly). However, Roblox staff are the only ones with that kind of power. They would have to implement that into the core structure of Studio. Which, as they stated in the linked thread, is totally doable — it just hasn’t been done yet.
This plugin listens for AttributeChanged, therefore it will not update currently existing Enum.EnumType.Value strings, but will on new changes.
The plugin alone will not detect and make changes in servers, it’s meant for use in Studio. You can have this done in-game using the following in either a server script or LocalScript:
Example (non-plugin) function
function waitForEnum(self)
local connection
connection = self.AttributeChanged:Connect(function(attributeName)
if typeof(self:GetAttribute(attributeName)) == "string" and string.find(string.sub(self:GetAttribute(attributeName),1,6),"Enum.") then -- Make sure attribute type is a string & the inputted text is predicted to be an Enum
if string.sub(self:GetAttribute(attributeName),1,5) == "/Enum" then connection:Disconnect() self:SetAttribute(attributeName,(string.gsub(self:GetAttribute(attributeName),"/",""))) return waitForEnum(self) end
local newEnumTable = string.split(self:GetAttribute(attributeName),".") -- eg. "Enum, Keycode, ButtonA"
if not newEnumTable[2] then return error("Invalid EnumType", 2) end -- No enum type inputted
if (newEnumTable[2] == "" or newEnumTable[2] == " ") then return end -- Kill function if "Enum." is the only string inputted
if not Enum[newEnumTable[2]] then return error("Invalid EnumType", 2) end -- Return error if no enum type exists for the given input (roblox will handle the error before reaching mine)
if not newEnumTable[3] or not Enum[newEnumTable[2]][newEnumTable[3]] then return error("Invalid EnumType value", 2) end -- Return (my) error if an invalid value is inputted for Enum's third position in the above table
if Enum[newEnumTable[2]] and Enum[newEnumTable[2]][newEnumTable[3]] then -- Confirm enum exists
self:SetAttribute(attributeName, Enum[newEnumTable[2]][newEnumTable[3]]) -- Set enum
end
end
end)
end
for i,descendant in pairs(game:GetDescendants()) do waitForEnum(descendant) end
game.DescendantAdded:Connect(waitForEnum) -- Do for all new descendants
Crude method I’d say, but it works
