So i have this code, which lets me fire cannonBalls whereever my mouse is located to. However if shoot at the sky, no cannonBall gets shooted:

local Debris = game:GetService("Debris")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local CollectionService = game:GetService("CollectionService")
local SoundService = game:GetService("SoundService")
local TweenService = game:GetService("TweenService")

local shootEffectOffset = 2 

local MousePositionEvent = ReplicatedStorage:WaitForChild("MousePositionEvent")

local function fireCannon(cannon, targetPosition)
	local firingPosition = cannon.Position + (cannon.CFrame.LookVector * shootEffectOffset)

	local shootEffect = Instance.new("Explosion")
	shootEffect.Position = firingPosition
	shootEffect.ExplosionType = Enum.ExplosionType.NoCraters
	shootEffect.BlastPressure = 0
	shootEffect.Parent = cannon
	Debris:AddItem(shootEffect, 0.2)

	SoundService.FireSound:Play()

	local clonedBall = ReplicatedStorage:FindFirstChild("CannonBall"):Clone()
	clonedBall.Position = firingPosition
	clonedBall.Parent = workspace.CannonBalls


	local heightDifference = targetPosition.Y - firingPosition.Y
	local midpoint = (firingPosition + targetPosition) / 2
	midpoint = Vector3.new(midpoint.X, midpoint.Y + heightDifference / 2, midpoint.Z)


	local tweenInfo = TweenInfo.new(1, Enum.EasingStyle.Quad, Enum.EasingDirection.Out)


	local goal = {}
	goal.Position = targetPosition


	local tween = TweenService:Create(clonedBall, tweenInfo, goal)

	tween.Completed:Connect(function(status)
		if status == Enum.PlaybackState.Completed then
			clonedBall:Destroy()
		end
	end)

	tween:Play()


	clonedBall.Touched:Connect(function(hit)
		local humanoid = hit.Parent:FindFirstChild("Humanoid")
		if humanoid then
			humanoid.Health = 0
		end

	
	end)

	Debris:AddItem(clonedBall, 1.25) 
end

MousePositionEvent.OnServerEvent:Connect(function(player, targetPosition)
	for _, cannon in CollectionService:GetTagged("Cannon") do
		fireCannon(cannon, targetPosition)
	end
end)

What does the client code for this look like? I would imagine the problem is that your client code is getting a “hit” position on a BasePart’s surface, and it doesn’t handle the case where there is no object in front of the mouse.

In this case, you probably want to set target position to something far away in the direction of the mouse. You can do this with:

local noPartPosition = mouse.Origin.Position + mouse.UnitRay.Direction * 1000
