Im just very confused on how you would do this. Would i Need to use a Table?. Would i need to use a function? Just would like some help on this.

Ive tried doing workspace:FindPartOnRayWithIgnoreList, But i dont know what else i could do.

local PartsToIgnore = {}
for _, Dsc in pairs(workspace:GetDescendants()) do
  if Dsc:IsA("Part") then PartsToIgnore(#PartsToIgnore + 1) = Dsc end
end

PartsToIgnore should be the 2nd parameter of workspace:FindPartOnRayWithIgnoreList(1, 2, 3, 4)

Got a error

Expected Identifier when parsing expression '='

This is in the Editor itself.

PartsToIgnore[#PartsToIgnore + 1]

Would i do


local PartsToIgnore = {}

for _, Dsc in pairs(workspace:GetDescendants()) do
    if Dsc:IsA("Part") then PartsToIgnore[#PartsToIgnore + 1] = Dsc end
end

workspace:FindPartOnRayWithIgnoreList(NewRay, PartsToIgnore, player.Character)

Ive Created the Ray and everything NewRay is a what im sending from the local script.

All the parts of the character should be in the partstoignore table, presuming that the character is loaded before the table is made.

Is this code in a localscript?

local Character = player.Character
local PartsToIgnore = {}

for _, Dsc in pairs(workspace:GetDescendants()) do
    if Dsc:IsA("Part") and not Dsc:IsDescendantOf(Character) then
      PartsToIgnore[#PartsToIgnore + 1] = Dsc 
  end
end

workspace:FindPartOnRayWithIgnoreList(NewRay, PartsToIgnore)

You have to reference the Character some way.

It insta kills me (even tried doing and Dsc:IsDescendantOf(Character))

Sorry, it’s whitelist.

workspace:FindPartOnRayWithWhitelist(NewRay, PartsToIgnore)

Im frustrated as well by my own project, so I’m not thinking clearly.

I hope you do really good on your project, but it says the Whitelist one is not a valid member

It works amazing thank you. I couldn’t have actually figured this out being the first time im using rays :sweat_smile:

No problem. Good luck!

SOLVE:

local Character = player.Character
local WhitelistParts= {}

for _, Dsc in pairs(workspace:GetDescendants()) do
    if Dsc:IsA("Part") and not Dsc:IsDescendantOf(Character) then
      WhitelistParts[#WhitelistParts+ 1] = Dsc 
  end
end

workspace:FindPartOnRayWithWhitelist(NewRay, WhitelistParts)

Also, im guessing if i wanted to i could do

for _, Dsc in pairs(workspace:GetDescendants()) do
    if Dsc:IsA("Part") and Dsc:IsA("MeshPart") and not Dsc:IsDescendantOf(Character) then
      WhitelistParts[#WhitelistParts+ 1] = Dsc 
  end
end

workspace:FindPartOnRayWithWhitelist(NewRay, WhitelistParts)

This is deprecated and could easily be reworked to use Raycast Params instead.
