In my game, I have two classes “Moveable” and “StackBottom” when both of these classes are instantiated, an instance is passed into the constructor which is the instance that these classes will act upon (create connections on, call methods on, etc.). When Moveable is instantiated, the tag “Moveable” is added to the instance using CollectionService. When StackBottom is instantiated, a hitbox is created which when touched will check if the part that touched it is a Moveable by checking if the instance has the tag “Moveable”.
I need to access the Moveable object that the instance is attached to within the StackBottom class in order to run a few sanity checks. However, I can’t think of a clean way to do so. Creating a ModuleScript that holds a dictionary of all objects in the game where the key is the instance and the value is the object seems stupid to me.
What would be the best way of going about this?
(Removed code not related to the question)
Moveable class:
local MoveableClient = {}
MoveableClient.__index = MoveableClient
function MoveableClient.new(model: Model): table
local self = setmetatable({}, MoveableClient)
self.model = model
CollectionService:AddTag(self.model, "Moveable")
self.isHovering = false -- I want to access these properties in the StackBottom class
self.isPickedUp = false
return self
end
return MoveableClient
StackBottom class:
local StackBottom = {}
StackBottom.__index = StackBottom
function StackBottom.new(model: Model)
local self = setmetatable({}, StackBottom)
self.janitor = Janitor.new()
self.model = model
self.ghostItem = nil
self.ghostItemStackable = nil
local modelCFrame, modelSize = self.model:GetBoundingBox()
self.hitBox = Instance.new("Part")
self.hitBox.Size = Vector3.new(7, 7, 7)
self.hitBox.CFrame = modelCFrame
self.hitBox.Transparency = 1
self.hitBox.CanCollide = false
local weld = Instance.new("WeldConstraint")
weld.Part0 = self.hitBox
weld.Part1 = self.model.PrimaryPart
weld.Parent = self.hitBox
self.hitBox.Parent = self.model
self.janitor:Add(RunService.RenderStepped:Connect(function()
local partsInHitbox = workspace:GetPartsInPart(self.hitBox)
if not self.ghostItem then
for _, part: Part in ipairs(partsInHitbox) do
if CollectionService:HasTag(part.Parent, "Moveable") then -- Checking tag here
self:_AddGhostStack(part.Parent)
end
end
else
local ghostItemInRange = false
for _, part: Part in ipairs(partsInHitbox) do
if part.Parent == self.ghostItemStackable then
ghostItemInRange = true
end
end
if not ghostItemInRange then
self:_RemoveGhostStack()
end
end
end))
return self
end
return StackBottom
