local castRay = Ray.new(mouseRay.Origin, mouseRay.Direction * 1000)
							
local hit, position = game.Workspace:FindPartOnRayWithIgnoreList(castRay, rayCastIgnoreList)

Why does this error appear?

#2

Which line exactly is erroring? It’s one of the parameters of the functions that’s wrong, for sure.

#3

Line 264, which is the second line in what i sent. I know its one of the parameters but I dont know which one or what is wrong with it.

#4

Can you show the line where you localled rayCastIgnoreList?
It seems like it’s not a table with objects.

#5 
rayCastIgnoreList = {ConnectionList, WireList}

for _, plr in pairs(game.Players:GetPlayers()) do
	if plr and plr.Character then
		table.insert(rayCastIgnoreList, plr.Character)
	end
end

local mouseRay = Mouse.UnitRay
local castRay = Ray.new(mouseRay.Origin, mouseRay.Direction * 1000)

local hit, position = game.Workspace:FindPartOnRayWithIgnoreList(castRay, rayCastIgnoreList)

Right now the two lists, ConnectionList and WireList are empty.

#6

If ConnectionList and WireList are NOT objects (if they are tables or something), then it will error, as the rayCastIgnoreList must only contain existing objects.

#7

ConnectionList and WireList are both tables, right? that’s likely your problem.
also use workspace:Raycast, because Ray.new is deprecated

Thanks. I will just use for loops to add their items into the main table.

Does it support ignorelists as well?

#10

Yes,

local params = RaycastParams.new()
params.FilterType = Enum.RaycastFilterType.Blacklist
params.FilterDescendantsInstances = {workspace.ignore}

it also supports collisiongroups
