Tables cannot be cyclic

[Rymxi (gav1n)]

i’m making a custom hitbox system rn, and im sending a metatable from server to client. The server makes the metatable, stating the properties, and invokes a remotefunction. The client then gets the hits and returns them.

Server-Side

function hitmodule:Start()
	keys[self.Key] = self
	
	self.Connection = RunService.Heartbeat:Connect(function()
		if self.Context == "Client" then
		local detectedParts = Hitbox:InvokeClient(self)
		
		local HitCharacter, Humanoid = unpack(detectedParts)
		self.Touched:Fire(HitCharacter, Humanoid)
		elseif self.Context == "Server" then
			hitmodule:_cast()
			hitmodule:_visual()
		end
	end)
end
