so the title explains it all so i want it to ignore everything but one part ive tried using findpartonraywithwhitelist but it comes out with an error Unable to cast value to Objects the line is this:
local _,Position,norm = workspace:FindPartOnRayWithWhitelist(raycast, part)
plz help also this says that FindPartOnRayWithWhitelist is a thing but i am having trouble with it
local SpecialParts = workspace.Folder -- the folder that holds all the parts that won't be ignored
local Ignored = {} -- table
local racast = Ray.new(OriginalPos, Direction) -- ray
for i, f in pairs(SpecialParts:GetChildren()) do -- all the parts that will not be ignored
for i, v in pairs(workspace:GetDescendants()) do -- **all** parts in workspace
if v:IsA("Part") then -- detecting if is a part
if v ~= f then -- if the parts are not the "special" ones
table.insert(Ignored, v) -- inserting all the ignored parts
end
end
end
end
local ignore = workspace:FindPartOnRayWithIgnoreList(raycast, Ignored) -- the ignored parts

You can Try This
local IgnoredList = {}
local racast = Ray.new(OriginalPos,Direction) --- case sensitive
local MyFavPart =---- this will be the part that wont be ignored
for _,Child in pairs (workspace:GetChildren()) do
if Child.Name ~= MyFavPart.Name then --- make sure myfavpart has a different name from any other objects
table.insert(IgnoredList,Child) ---- adding the part to the ignored list
end
local Launcher,Position = Workspace:FindPartOnRayWithIgnoreList(raycast,IgnoredList)
after this while loop the Launcher hope this works
you're missing an end btw
so i don't want to rename every single part because the favpart can potentally be any part in the workspace so on line 5 i was wondering could i do if Child ~= MyFavPart then?
also what if the part is in a folder in workspace?
