FindPartOnRayWithIgnoreList Material Argument

Help and Feedback Scripting Support
#1

  1. What do you want to achieve? I want to Raycast and ignore the glass material

  2. What is the issue? Is this possible?

  3. What solutions have you tried so far? I Googled but I didn’t find out if you can put a material Enum as ignore

Filter certain materials when casting ray
#2

You can perhaps search for all glass material parts in the workspace and put them in the ignore table.

#3

Create a recursive function with an ignore list as a parameter.
Do the usual ray stuff however if the ray hit a part which is made out of glass, put that part in the ignore list table and call the function again with the ignore list.

#4

Oh, that makes sense. Will probably post a feature request for this tho so that it doesn’t have to be more complicated than it needs to be

Following @BBQIsTasty’s idea, but with a more optimised approach, you can just use :FindPartOnRayWithIgnoreList() normally, put it in a repeat loop until the part that it returns isn’t a glass material, and each time the part is put into an ignore table.

local ignore = {}
local ray = this would be your ray
repeat 
   local part = workspace:FindPartOnRayWithIgnoreList(ray, ignore)
   table.insert(ignore, part)
until part.Material == "Glass"
table.remove(#ignore) --after we found the part that isn't a glass material, we would remove the last member of the table (which is the part that wasn't glass, because we add them no matter what)
#6

You could just add every single glass part to your ignore list and go from there. No need for a loop or anything of that sort. For doing this, I recommend CollectionService.

In addition to what colbert2677 has said, I recommend using this plugin to add CollectionService tags:

To optimize this I would probably raycast from the place that the ray hit the glass part, so that you aren’t repeatedly doing long ray casts and instead doing shorter ray casts.
