Raycast not raycasting

Hello guys, I recently wanted to use raycast with FilterType of Include (like shown below):

RayParams2.FilterType = Enum.RaycastFilterType.Include
RayParams2.FilterDescendantsInstances = {game.Workspace.PetCorrectionFolder:WaitForChild("PetWalkingPart")}

local RayResult1 = workspace:Blockcast(Pet.PrimaryPart.CFrame, Pet.PrimaryPart.Size, Vector3.new(0, -10, 0), RayParams2)

and for some reason, even with a very big part and very clear collision, it doesnt give me any resoults. I tried changing almost every variable and it feels like its just broken on roblox side but I’m just probablly dumb and dont see a mistake somewhere.

If anyone knows why is it happening, pls help :pray:



Can I get more information about RayParams2? Just send me the whole code. I may be able to help on this one!


well, there is not much more to it but here you have the whole code:

local RunService = game:GetService("RunService")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Players = game:GetService("Players")

local PetsFolder = game.Workspace:WaitForChild("PlayerPets")

local Spacing = 5
local PetSize = 3
local MaxClimbHeight = 5

local RayParams = RaycastParams.new()
local RayParams2 = RaycastParams.new()
local RayDirection = Vector3.new(0, -100, 0)

local function RearrangeTables(Pets, Rows, MaxRowCapacity)
	local AOR = math.ceil(#Pets / MaxRowCapacity)
	for i = 1, AOR do
		table.insert(Rows, {})
	for i, v in Pets do
		local Row = Rows[math.ceil(i / MaxRowCapacity)]
		table.insert(Row, v)

local function GetRowWidth(Row, Pet)
	if Pet ~= nil then
		local SpacingBetweenPets = Spacing - Pet.PrimaryPart.Size.X
		local RowWidth = 0
		if #Row == 1 then
			return 0
		for i, v in Row do
			if i ~= #Row then
				RowWidth += Pet.PrimaryPart.Size.X + SpacingBetweenPets
				RowWidth += Pet.PrimaryPart.Size.X
		return RowWidth

	for i, PlayerPetFolder in pairs(PetsFolder:GetChildren()) do
		if not Players:FindFirstChild(PlayerPetFolder.Name) then return end
		local Character = Players[PlayerPetFolder.Name].Character or Players[PlayerPetFolder.Name].CharacterAdded:Wait()
		local HRP = Character:WaitForChild("HumanoidRootPart")
		local Humanoid = Character:WaitForChild("Humanoid")
		if Character == nil or HRP == nil or Humanoid == nil then return end
		local Pets = {}
		local Rows = {}
		for _, v in pairs(PlayerPetFolder:GetChildren()) do
			table.insert(Pets, v)
		RayParams.FilterDescendantsInstances = {Character, PetsFolder}
		RayParams2.FilterType = Enum.RaycastFilterType.Include
		RayParams2.FilterDescendantsInstances = {game.Workspace.PetCorrectionFolder:WaitForChild("PetWalkingPart")}
		local MaxRowCapacity = math.ceil(math.sqrt(#Pets))
		RearrangeTables(Pets, Rows, MaxRowCapacity)
		for i, Pet in Pets do
			local RowIndex = math.ceil(i / MaxRowCapacity)
			local Row = Rows[RowIndex]
			local RowWidth = GetRowWidth(Row, Pet)
			local XOffset = #Row == 1 and 0 or RowWidth / 2 - Pet.PrimaryPart.Size.X / 2
			local X = (table.find(Row, Pet) - 1) * Spacing
			local Z = RowIndex * Spacing
			local Y = 0
			local RayResult1 = workspace:Blockcast(Pet.PrimaryPart.CFrame, Pet.PrimaryPart.Size, Vector3.new(0, -10, 0), RayParams2)
			if RayResult1 then
				if RayResult1.Instance.Parent.Name == "PetCorrectionFolder" then
					MaxClimbHeight = 100
				MaxClimbHeight = 5
			local RayResult = workspace:Blockcast(Pet.PrimaryPart.CFrame + Vector3.new(0, MaxClimbHeight, 0), Pet.PrimaryPart.Size, RayDirection, RayParams)
			if RayResult then
				Y = RayResult.Position.Y + Pet.PrimaryPart.Size.Y / 2
			else -- Using HRP
				print("used HRP")
				Y = HRP.CFrame.Y
			--local TargetCFrame = CFrame.new(HRP.CFrame.X, 0, HRP.CFrame.Z) * HRP.CFrame.Rotation * CFrame.new(X - XOffset, (Y + 1) + (math.sin(tick()) / 3), Z)
			local TargetCFrame = CFrame.new(HRP.CFrame.X, 0, HRP.CFrame.Z) * HRP.CFrame.Rotation * CFrame.new(X - XOffset, Y, Z)
			Pet.PrimaryPart.CFrame = Pet.PrimaryPart.CFrame:Lerp(TargetCFrame, 0.1)
			if Pet.PrimaryPart.CFrame.Y <= -100 then
				Pet.PrimaryPart.CFrame = CFrame.new(Pet.PrimaryPart.CFrame.X, HRP.CFrame.Y, Pet.PrimaryPart.CFrame.Z)

Maybe you can print the values of what is being put in the ray cast. Also, Maybe check the direction, I could be in a different direction or what. I don’t understand what is supposed to happen. Maybe make a script where you just make the ray cast and test to see if it works and try to add it into the main script. I would try all of these.

the initial idea was to detect when the pet is in a designated area but for some reason it doesnt detect it at all. It works perfectly fine with detecting stuff if you set the FilterType to Exclude, not Include

Maybe check the thing you are filtering “game.Workspace.PetCorrectionFolder:WaitForChild(“PetWalkingPart”)” Maybe it can be the wrong thing you are trying to detect or something. Try to see if it could be nil.

nvm I fixed it, not sure how but I assume the raycast wasn’t hitting the part cus it wasn’t below it but in it I think

Great! Did I at least help you? Good luck with your pet game!

a bit but I mostly just tried some random stuff and it worked :eyes:

oh an btw, do you know if I can make Streaming Enabled ignore some parts I want?

If you set a model’s ModelStreamingMode property to “Persistent” it should never stream out, assuming that’s what you want. This applies to everything inside the model

I found a way around it but this would prob work too, thx :+1:
