Hey!
I have made a placement system and I forgot to add a part to the system, which is a box that separates towers. What I mean is something like this:
This would be allowed:
This wouldn’t be allowed:
I have had a go at this, but since raycast only returns a single target and not multiple it is impossible to tell, I also then ran into it falling when in placing mode:

You may need to pay attention, but the box just falls threw everything
I did weld this. The range circle which displays how far the tower can reach is welded the same way, yet, it doesn’t have the same issue.
The code:
local RunService = game:GetService("RunService")
local UserInputService = game:GetService("UserInputService")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local PhysicsService = game:GetService("PhysicsService")
local getMap = ReplicatedStorage.SelectedMap
if not getMap.Value then
getMap:GetPropertyChangedSignal("Value"):Wait()
end
local getReplicatedMap = ReplicatedStorage.Maps:FindFirstChild(tostring(getMap.Value))
if not getReplicatedMap then
error("REPLICATED MAP: "..getMap.Name.." DOES NOT EXIST")
end
local PlacementEvents = ReplicatedStorage:WaitForChild("PlacementEvents")

local spawnTowerEvent = PlacementEventsMain:WaitForChild("SpawnTower")
