Raycast/Mouse help

Trying to make it so that my raycast ignores all can collidable parts.

I made it ignore it in the raycast, however it for some reason like because the mouse still sees the collidable part, it disorts it and gives me this weird issue. I want to figure out how to raycast to where the mouse is clicked and ignore certain parts completely.

Heres a video:
https://i.gyazo.com/00a3770476c0eb973a0397b580a2ce23.mp4

Code: (has extra parts taken out ofc)

function Framework:Raycast(Origin, EndPos, IgnoreList, Range, CallCheck, MaxRunTimes, RunTimes)
	local Params = RaycastParams.new();
	local Distance = (EndPos - Origin).unit;
	local RayResults 

	Params.FilterType = Enum.RaycastFilterType.Exclude;
	Params.IgnoreWater = true;
	Params.FilterDescendantsInstances = IgnoreList; -- includes the collideable part

	RayResults = workspace:Raycast(Origin, Distance * Range, Params);

    return RayResults
end

--  how its called
local RayResults = self:Raycast(self.Tool.Main.CFrame.p, Vector3.new(mousePos.x + (math.random() * (spread * 2) - spread), mousePos.y + (math.random() * (spread * 2) - spread), mousePos.z + (math.random() * (spread * 2) - spread)), self:GetIgnoreList(game.Players.LocalPlayer.Character), self.Config.Range and self.Config.Range or 500, function(RayResults)
	if RayResults.Instance:IsDescendantOf(workspace.Assets.Interactables.Vehicles) then return false end

	if RayResults.Instance.CanCollide == false or RayResults.Instance.Transparency == 1 then 
		return true
	end

	if RayResults.Instance:IsDescendantOf(workspace.CurrentCamera) then 
		return true 
	end

	return false
end, self.Config.MaxRetries and self.Config.MaxRetries or 10)

Basically i need a different way to get mouse hit or have the mouse ignore a part for the raycast

its because of how you get mousePos, im guessing right now you’re using mouse.Hit.p, which is probably causing this issue
i would use camera:ViewportPointToRay() with the mouse’s position, and then from the ray you can get it’s Direction

I am assuming you’re using mouse.Hit.p, which is most likely where the issue originates. I had a script that operated similar to yours, and my solution worked out well.

Try using a raycast via camera:ViewportPointToRay.

So I tried that and I got a issue of it seeming off from where im clicking; heres the code

local tool = script.Parent
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
local ignoreParts = {}

local function castLaser()
	local handle = tool:FindFirstChild("Handle")
	if not handle then 	return end

	local rayOrigin = handle.Position
	local ray = workspace.CurrentCamera:ViewportPointToRay(mouse.X, mouse.Y)
	local rayDirection = ray.Direction * 1000 

	local rayParams = RaycastParams.new()
	rayParams.FilterType = Enum.RaycastFilterType.Exclude
	rayParams.FilterDescendantsInstances = ignoreParts
	rayParams.IgnoreWater = true

	local result = workspace:Raycast(rayOrigin, rayDirection, rayParams)

	local laser = Instance.new("Part")
	laser.Anchored = true
	laser.CanCollide = false
	laser.Material = Enum.Material.Neon
	laser.BrickColor = BrickColor.new("Bright red")
	laser.Size = Vector3.new(0.2, 0.2, (result and (rayOrigin - result.Position).Magnitude) or 1000)
	laser.CFrame = CFrame.new(rayOrigin, rayOrigin + rayDirection) * CFrame.new(0, 0, -laser.Size.Z / 2)
	laser.Parent = workspace

	game:GetService("Debris"):AddItem(laser, 0.1)

	return result
end

tool.Activated:Connect(function()
	castLaser()
end)


for i,v in pairs(workspace:GetDescendants()) do 
	if v:IsA("BasePart") and v.CanCollide == false then 
		table.insert(ignoreParts, v)

	end
end

is it off only vertically, like is it shooting above your mouse or below it? if it is, then try using ScreenPointToRay instead of ViewportPointToRay because it accounts for the inset that Mouse.X/Mouse.Y have
