Can you send the script here so I can take a look?

#22

Forgot to include, I’ve updated the API Reference a little bit to show the properties in a better style.

#23

This is the script:

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local CollectionService = game:GetService("CollectionService")

local ClassPP = require(ReplicatedStorage["Class++"])
local class = ClassPP.class


local toolClass = class "Tool" {
	
	constructor = function(self, tool)
		
		if tool and tool:IsA("Tool") then
		
			self.Tool = tool
			self.Configuration = require(self.Tool.Config) 

			self.Tool.Equipped:Connect(function()
				
				self.equipped = true
			end)
			self.Tool.Unequipped:Connect(function()
				
				self.equipped = false
			end)
		end
	end,
	Public = {
		equipped = false,
		Tool = nil,
		Configuration = {},
	}
}

CollectionService:GetInstanceAddedSignal("Tool"):Connect(function(tool)
		
	if tool:IsA("Tool") then
		
		local newTool = toolClass.new(tool)
	end
end)

This is the Error : {Class++}: This class has no member named "Tool".

#24

I see what you mean now, this is a common mistake that people encounter when creating classes using my module.

This is mostly related on how dictionaries work in Luau, when you set a key to nil, you’re actually removing that key from the table. In this case, the key Tool is being set to nil in the Public access specifier, and since you’re setting the key Tool to nil, Lua automatically removes it from the table, which in the final classData, the Tool member does not exist.

To solve this issue, instead of setting it to nil, you can set it to false.
Here’s your updated code:

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local CollectionService = game:GetService("CollectionService")

local ClassPP = require(ReplicatedStorage["Class++"])
local class = ClassPP.class


local toolClass = class "Tool" {
	
	constructor = function(self, tool)
		if tool and tool:IsA("Tool") then
			self.Tool = tool
			self.Configuration = require(tool.Config) 

			self.Tool.Equipped:Connect(function()
				self.equipped = true
			end)

			self.Tool.Unequipped:Connect(function()
				self.equipped = false
			end)
		end
	end,
	Public = {
		equipped = false,
		Tool = false,
		Configuration = {},
	}
}

Release Beta 1.4.0

  • Performance improvements.
  • Fixed some bugs.
  • Updated the final method to support functions with the syntax below:
local class, final = ClassPP.class, ClassPP.final

local Test = class "Test" {
	Public = {
		test = final(function(self, ...) 
			print(self, ...)
		end),
	}	
}

A performance comparison picture between 1.3.1 and 1.4.0:

Release 1.0.0

Class++ is finally complete and out of beta! I can’t really think of adding any new features, so this is going to be the last version for now.
Until I get a new idea or find an efficient method to implement certain ideas that I currently have, the only updates there will ever be are performance updates and bug fixes. (And maybe some internal changes)
Thanks for using my module!

  • Updated the source code to be more efficient and clean, and removed unnecessary comments from the code.
  • Updated certain internal functions to be more performant.
  • Added a new documentation page describing how to use type checking with Class++. (It’s very useful, check it out!)
  • Fixed certain parts of the documentation.
  • Removed final functions (using the final keyword with functions), unfortunately implementing final functions required some internal changes that weren’t very worth it for this feature, so I decided to remove it altogether, you can use other methods or just use final classes instead.
    (The final keyword now works as it was in 1.3.1)

If you have any new feature ideas, or found bugs, please don’t hesitate to create a feature request or a bug form though!

Updated the documentation page to give a better explanation on the Type API!

#29

Release 1.0.1

  • Members of Friend Access Specifier no longer replicate to the objects as they’re only used within the class object itself.
  • Updated the documentation.
#30

Release 1.1.0

  • Class++ objects now support type checking! This was an update that I was planning to do for a very long time, and it would not have been possible without @HugeCoolboy2007.
    • All of the created objects should now have type completion for the members stored in the Public access specifier.
    • Creating custom types is no longer needed, however, if you still want to use the full features of type checking in Luau, it’s still recommended that you use custom types for your classes.
    • For more info, check out this documentation page.
  • Util and Type modules now fully support the class type.
  • Updated the documentation.

(@arbitiu turns out it was possible lol.)

Well it’s still in beta, so I think I have plenty of time to fix things up, but I didn’t know it would be this broken :sob:
