Not working RaycastFilter Exclude

Help and Feedback Scripting Support
#1

Im trying to make Tower Defense, and im using RaycastFilter, Exclude. But its not working.
The tower is still flying to camera! (I named it as TTs).

I want it stay on ground not fly to the gods!

local uis = game:GetService("UserInputService")
local msPoss
local TTs
local placing = false
local function msraycast()
	local msPos = uis:GetMouseLocation()
	local cam = workspace.CurrentCamera
	local msray = cam:ViewportPointToRay(msPos.X, msPos.Y)
	local rParams = RaycastParams.new()
	
	rParams.FilterType = Enum.RaycastFilterType.Exclude
	rParams.FilterDescendantsInstances = {TTs}
	local raycastR = workspace:Raycast(msray.Origin, msray.Direction * 1000)
	return raycastR
end

local function AddPlaceHolderTower(towerName)
	local tower = game.ReplicatedStorage.Towers:FindFirstChild(towerName)
	if tower then
		TTs = tower:Clone()
		TTs.Parent = workspace.Towers
		
	end

end
game.ReplicatedStorage.RemoteEvent.OnClientEvent:Connect(function(tower)
	AddPlaceHolderTower(tower)
end)


uis.InputBegan:Connect(function(inp)
	if inp.UserInputType == Enum.UserInputType.MouseButton1 then
			
	end
end)


game:GetService("RunService").RenderStepped:Connect(function()
	if TTs then
		local result = msraycast()
		if result and result.Instance then
			local x = result.Position.X
			local y = result.Position.Y + TTs.Humanoid.HipHeight + (TTs.PrimaryPart.Size.Y / 2)
			local z = result.Position.Z

			local cframe = CFrame.new(x,y,z)
			TTs:SetPrimaryPartCFrame(cframe)
		end
	end
	
end)

Hello, the issue is very simple:
local raycastR = workspace:Raycast(msray.Origin, msray.Direction * 1000)

You did not include rParams in your raycast.
Simply change it to:

local raycastR = workspace:Raycast(msray.Origin, msray.Direction * 1000, rParams)

Thanks to you sir.
This was helpfull)

#4

but also if you know how to fix
The TTs (tower to spawn) still half in ground.
local y = result.Position.Y + TTs.Humanoid.HipHeight + (TTs.PrimaryPart.Size.Y / 2)
Here im changing the Y position. But its not working as i expected it to.

#5

Perhaps try using :GetExtentsSize()

  • So if TT is the whole model, TT:GetExtentsSize().Y/2, then add that with result.Position.Y

No problem and best of luck to you

can i ask you again, im still working on placement, but its not globalized and creating a total copy of Tower To spawn.

So i need to make Spawn System, This is Local Script, when i click Left Mouse Button, its spawns some kind of Tower, but its spawns A total copy of Tower To Spawn.

LOCAL SCRIPT (“Tower Mananger”)

local uis = game:GetService("UserInputService")
local msPoss
local TTs
local placing = false
local canplace = false
local function msraycast()
	local msPos = uis:GetMouseLocation()
	local cam = workspace.CurrentCamera
	local msray = cam:ViewportPointToRay(msPos.X, msPos.Y)
	local rParams = RaycastParams.new()

	rParams.FilterType = Enum.RaycastFilterType.Exclude
	rParams.FilterDescendantsInstances = {TTs}
	local raycastR = workspace:Raycast(msray.Origin, msray.Direction * 1000, rParams)
	return raycastR
end

local function AddPlaceHolderTower(towerName)
	local tower = game.ReplicatedStorage.Towers:FindFirstChild(towerName)
	if tower then
		TTs = tower:Clone()
		TTs.Parent = workspace.Towers
		for i, trash in ipairs(TTs:GetDescendants()) do
			if trash:IsA("BasePart") then
				trash.Material = Enum.Material.ForceField
				trash.CollisionGroup = "Towers"
			end
		end

	end

end
local function ColorPlaceHolderTower(color)
	for i, object in ipairs(TTs:GetDescendants()) do
		if object:IsA("BasePart") then
			object.Color = color
		end
	end
	
end
game.ReplicatedStorage.RemoteEvent.OnClientEvent:Connect(function(tower)
	AddPlaceHolderTower(tower)
end)


uis.InputBegan:Connect(function(inp, proc)
	if proc then
		return
	end
	if TTs then
		if inp.UserInputType == Enum.UserInputType.MouseButton1 and canplace then
			game.ReplicatedStorage.SpawnTroop:FireServer(TTs.Name, TTs.PrimaryPart.CFrame)
			TTs = nil
			
		end
	end
	
end)


game:GetService("RunService").RenderStepped:Connect(function()
	if TTs then
		local result = msraycast()
		if result and result.Instance then
			if result.Instance.Parent.Name == "TowerArea" then
				ColorPlaceHolderTower(Color3.new(0,1,0))
				canplace = true
				
			else
				ColorPlaceHolderTower(Color3.new(1,0,0))
				canplace = false
			end
			local x = result.Position.X
			local y = result.Position.Y + TTs:GetExtentsSize().Y/2
			local z = result.Position.Z

			local cframe = CFrame.new(x,y,z)
			TTs:SetPrimaryPartCFrame(cframe)
		end
	end

end)

Script (“Spawner”)

function Spawns(plr, name, cframe)
	print(plr, name, cframe)
	local tower = game.ReplicatedStorage:FindFirstChild(game.ReplicatedStorage.Towers:FindFirstChild(name))
	if tower then
		local tts = tower:Clone()
		local adjustedCFrame = cframe + Vector3.new(0, 5, 0)
		tts:SetPrimaryPartCFrame(adjustedCFrame)
		tts.Parent = workspace.Towers
		tts.HumanoidRootPart:SetNetworkOwner(nil)

	end
end
game.ReplicatedStorage.SpawnTroop.OnServerEvent:Connect(function(plrr, namee, cfr)
	Spawns(plrr, namee, cfr)
end)
