Mouse.Hit leading to a dumbfoundingly incorrect position

Help and Feedback Scripting Support
#1

No matter where i point my mouse, the projectile i am attempting to shoot always heads in this general direction.

Whenever i print out the Mouse.Hit.LookVector, it is never the same, but only mildly different.
image
Here is my code (ignore the comments, i was previously using bodyvelocity)

print(pos)
	paintball.CFrame = CFrame.lookAt(shootpart.Position,pos)
	--paintvel.Parent = paintball
	--paintvel.Velocity = pos.LookVector * 100
	--game.Debris:AddItem(paintvel,10)
	task.spawn(function() -- movement
		for count = 100,0,-1 do
			wait(0.1)
			if expired == false then
			paintball.CFrame += paintball.CFrame.LookVector * 5
			end
		end
	end)

“pos”, in this case, is the Mouse.Hit.LookVector being fired from the client and being assigned to the pos variable in a remove event.
I’ve struggled with projectiles beforehand, but this is a new issue to me.

I apologize if this is not coherent, or enough context, i can share more code if needs be (but this is arguably all that is relevant).

#2

Can you please show me the entire code or atleast most of it so I can understand what is happening more?

#3

I am unsure what else to provide, but i will provide as much as i can.

function shoot()
	local expired = false
	wait(0.5)
	ammo.Value -= 1
	handle.shoot:Play()
	local paintball = Instance.new("Part")
	--local paintvel = Instance.new("BodyVelocity")
	paintball.Shape = Enum.PartType.Ball
	paintball.BrickColor = BrickColor.Random()
	paintball.Size = Vector3.new(0.5,0.5,0.5)
	paintball.Parent = workspace
	paintball.Anchored = true
	--paintball.CFrame = shootpart.Position
	print(pos)
	paintball.CFrame = CFrame.lookAt(shootpart.Position,pos)
	--paintvel.Parent = paintball
	--paintvel.Velocity = pos.LookVector * 100
	--game.Debris:AddItem(paintvel,10)
	task.spawn(function() -- movement
		for count = 100,0,-1 do
			wait(0.1)
			if expired == false then
			paintball.CFrame += paintball.CFrame.LookVector * 5
			end
		end
	end)
	game.Debris:AddItem(paintball,10)

This is essentially the entire shooting function, except for the part where the projectile makes contact with a surface (It is separate, and is working fine)

The code below is the entire function in the LocalScript of the tool that i am using, as you can see i am transferring the Hit.Lookvector correctly through a remoteevent.

tool.Activated:Connect(function()
	if not gunshootanim then gunshootanim = tool.Parent.Humanoid.Animator:LoadAnimation(gunshoot) end
	if shootdb == false and ammo.Value > 0 then
	task.spawn(function()
		shootdb = true
		wait(gunshootanim.Length)
		shootdb = false
	end)
	gunshootanim:AdjustSpeed(1.5)
	gunshootanim.Priority = Enum.AnimationPriority.Action4
	gunshootanim:Play()
	ev:FireServer(mouse.Hit.LookVector) 
	end
end)

I can provide more.

I’m still confused where you’re getting “pos” from

#5

This is the nature of :GetMouse(), old, unreliable, inaccurate, you are better off using a custom mouse module that uses raycasts.

#6

“pos” is initially a variable defined at the beginning of my server script, and the mouse part of ev:FireServer(mouse.Hit.LookVector) IS the “pos” itself.
It is recieved on the server script through the “ev” remote event, where pos is set to the mouse’s hit lookvector.

#7

Noted. But is that the only solution?

#8

use Mouse.Origin.LookVector instead

#9 
game.Players.LocalPlayer:GetMouse().Position

or

local UserInputService = game:GetService("UserInputService")
local mouseLocation = UserInputService:GetMouseLocation()

local camera = workspace.CurrentCamera
local mousePos = camera:ScreenPointToRay(mouseLocation.X, mouseLocation.Y)

-- raycast
