Raycast CFrame not accurate at random intervals

Help and Feedback Scripting Support
#1

I have a Raycast code that makes it so you can place down Towers in my Tower Defense game, and at rare intervals, the raycast CFrame is a location that the mouse was NOT at. For example, in the middle of the map (not the origin weirdly enough). Is there any way to make this Raycast more accurate? I used this video as a Tutorial. Tower Placement - Tower Defense Tutorial #6 - YouTube

Local Script with Raycast in it:

local function MouseRaycast(model)
	local mousePosition = UserInputService: GetMouseLocation()
	local mouseRay = camera: ViewportPointToRay(mousePosition.X, mousePosition.Y)
	local raycastParams = RaycastParams.new()
	local blacklist = camera:GetChildren()
	for i, playerpart in pairs(Players:GetPlayers()) do
		local playerpartstoadd = player.Character:GetChildren()
		table.insert(blacklist, playerpartstoadd)
	end
	table.insert(blacklist, model)
	raycastParams.FilterType = Enum.RaycastFilterType.Blacklist
	raycastParams.FilterDescendantsInstances = blacklist
	
	local raycastResult = workspace:Raycast(mouseRay.Origin, mouseRay.Direction * 1000, raycastParams)
	
	return raycastResult
end

RunService.RenderStepped:Connect(function()
	local result = MouseRaycast(towerToSpawn)
	if result and result.Instance then
		if towerToSpawn then
			hoveredInstance = nil
			currentbearheld = towerToSpawn.Name
			if result.Instance.Parent.Name == "TowerArea" or result.Instance.Parent.Parent.Name == "TowerArea" then
				canPlace = true
				ColorPlaceholderTower(Color3.fromRGB(139, 255, 133))
			else
				canPlace = false
				ColorPlaceholderTower(Color3.fromRGB(255, 121, 123))
			end
			local x = result.Position.X
			local y = result.Position.Y + towerToSpawn.Humanoid.HipHeight + (towerToSpawn.PrimaryPart.Size.Y / 2)
			local z = result.Position.Z

			local cframe = CFrame.new(x,y,z) * CFrame.Angles(0, math.rad(rotation), 0)
			towerToSpawn:SetPrimaryPartCFrame(cframe)
		else
			hoveredInstance = result.Instance
		end
	else
		hoveredInstance = nil
	end
	
end)

Part of local script that invokes server to spawn tower:

local function SpawnNewTower()
		if canPlace then
			local placedtower = spawnTowerFunction:InvokeServer(towerToSpawn.Name, towerToSpawn.PrimaryPart.CFrame)
			if placedtower then
				placedTowers += 1
				gui.Info.BearLimitFrame.BearLimit.Text = "Bears: " .. placedTowers .. "/" .. maxTowers
				holdingbear = false
				RemoveBear()
				UpdateToggleView()
				currentbearheld = nil
			end
		end
end

Not sure what i need to send, most of the code is from the tutorial, just wanted to post what i thought would be important for figuring out this issue.

#2

Try using mouse.Hit instead of casting you rays from the mouses position on the screen

#3

This is what happens when i change the placement itself to Mouse.Hit. It takes the currentcamera and just makes the tower “point” at where i hit the mouse button.

#4

What exactly does the original offset look like? Also try using the camera’s CFrame’s position instead of the rays origin

#5

Also what if you try blacklisting the player’s character instead

#6

I found the problem it’s here

local raycastResult = workspace:Raycast(mouseRay.Origin, -> <- mouseRay.Direction  * 1000, raycastParams)

its ray casting to the direction but not from the origins postion try adding the mouseRay.Origin to the mouseRay.Direction

mouseRay.Origin + mouseRay.Direction * 1000
