Im making a placement system and i am trying to decide which is better to determine the position of the object im placing. Mouse.Hit or Mouse.UnitRay?

I only used Mouse.Hit and in this case I would use Mouse.Hit. I think that getting a CFrame of where player’s mouse is pointing in 3D space is better than raycasting from player’s camera to mouse location. I think that reading Mouse.UnitRay API might be useful: Mouse.UnitRay (roblox.com).

Mouse.Hit.p may also be of use to you. If you prefer working with Vector3 values over CFrame values that is.

Mouse.Hit.p is deprecated, you should use Mouse.Hit.Position

here is how to do it using UserInputService

local userInputService = game:GetService("UserInputService")
local camera = workspace.CurrentCamera
local raycastParams = RaycastParams.new()

local function GetMouseHit()
    local mouse = userInputService:GetMouseLocation()
    local ray = camera:ViewportPointToRay(mouse.X, mouse.Y)
    local raycastResult = workspace:Raycast(ray.Origin, ray.Direction * 1000, raycastParams)
    if raycastResult == nil then
        return ray.Origen + ray.Direction * 1000
    else
        return raycastResult.Position, raycastResult.Instance
    end
end

while true do
    local hit, target = GetMouseHit()
    print(hit, target)
    task.wait(1)
end

and now you get all the benefits of using RaycastParams and RaycastResult

This is actually the best way to get mouse hit currently
