This will not work and will give an error.
You can just do this instead:

raycastParams.FilterDescendantsInstances = {script.Parent.Parent}

Oh shoot you’re right great catch.

Another thing you can do is

local filterLiist = {} -- assuming you're excluding more instances than just the character

if char then
    table.insert(filterList, char)
    raycastParams.FilterDescendantsInstances = filterList
end

If you do this filterList I’d recommend to cleanup instances from the filter list if they’ve been destroyed/removed from game

how would you do that from a serverscript?
is it smart to do it from a serverscript (exploit security)
or why? not?

So whenever you’re raycasting if you add something to the FilterDescendantsList and you have a RaycastFilterType it will either only find a result with or without what’s in the FilterDescendantsList.

If you’re trying to raycast to a part with CanQuery set to false it won’t find it because it can’t query that part.

In addition, you aren’t required to have a RaycastFilter it’s just incase you want to ONLY include certain instances, or ignore them

oh. does it lag if i cast like 10 raycasts every renderstep?

It shouldn’t lag to be honest there’s games that do tons of raycast per frame such as FPS games. Setting the distance super high might cost more in performance though I believe.

OK: mind having a look at my finished script? i might have done some stupid unnecessar stuff

Raycasting is normally filtered by CanQuery, although RaycastParams has a .RespectCanCollide property which allows it to be filtered by CanCollide instead.

You should never need more than 1 raycast in the same direction every frame.
