RunService.Heartbeat:Connect(function()
		for objectIndex, object in workspace:GetDescendants() do
			if object.Name:match("Interactable") then
				if object:GetAttribute("Pressed") == true then continue end
				
				local findHitbox = object:FindFirstChild("Hitbox")
				if not findHitbox then continue end
				
				local distance = (findHitbox.Position - Character.HumanoidRootPart.Position).Magnitude
				
				if distance <= 7 then
					interactableNear = object
					Shared.Guis.HUD.InteractLabel.Visible = true
					Shared.Guis.HUD.InteractLabel.Text = "[E] To "..object:GetAttribute("InteractName")
				elseif distance > 7 and interactableNear == object then
					Shared.Guis.HUD.InteractLabel.Visible = false
					interactableNear = nil
				end
				
				if interactableNear ~= nil then
					if (Character.HumanoidRootPart.Position - findHitbox.Position).magnitude < (interactableNear.Hitbox.Position - Character.HumanoidRootPart.Position).magnitude then
						interactableNear = object
						Shared.Guis.HUD.InteractLabel.Visible = true
						Shared.Guis.HUD.InteractLabel.Text = "[E] To "..object:GetAttribute("InteractName")
					end
				end
			end
		end
	end)

This is my code for nearest interactable. But if there are lets say 2 interactable’s like close to each other. It kind of bugs out. I want it to choose the NEAREST to the player. and also they are able to use the interactable behind a wall.

Why not use proximity prompts?

(Also, I made a customizable proximity prompt wrapper, you could try out too)
