Put your code in a code block for it to be easier to read and don't put inappropriate words in your code MarkedTomato 810 — 3y

Problem:

You forgot to introduce the curly braces, which look like this {} on line 6 where it says workspace.Part.

The reason it didn't work is because the script thinks that you're trying to set the value, which in this case is raypart to an object, which is the part, remember that FilteringStrings are arrays.(tables)

Solution:

Add the curly braces on line 06.

Fixed Code:

local part = script.Parent
local badpart = game.Workspace.shit
while true do
    wait(1) 
    raypar = RaycastParams.new()
    raypar.FilterDescendantsInstances = {workspace.shit}
    raypar.FilterType = Enum.RaycastFilterType.Blacklist
    local origin = part.Position
    local direction = part.CFrame.LookVector * 100
    local result = workspace:Raycast(origin, direction, raypar)
    if result then
        print(result.Instance.Name)
    end
    if not result  then
        print("nothing")
    end
end
