Raycast going through a part

Help and Feedback Scripting Support
#1

Yo, I’m new to this raycast thingy, So I got this from a forum post a long time ago ( I can’t find it )

LocalScript: ( Not full Script )

local Players = game:GetService("Players")

local Tool = script.Parent
local Handle = Tool:WaitForChild("Handle")
local Mouse = Players.LocalPlayer:GetMouse()
local Character = Players.LocalPlayer.Character
local Camera = game.Workspace.CurrentCamera

local function RaycastMouse()
	local Blacklist = {}
	
	-- ignore self
	for i, Baseparts in pairs(Character:GetDescendants()) do
		if Baseparts:IsA("BasePart") then
			table.insert(Blacklist, Baseparts)
		end
	end
	
	-- ignore parts with no collisions
	for i, Baseparts in pairs(game.Workspace:GetDescendants()) do
		if Baseparts:IsA("BasePart") then
			if Baseparts.CanCollide == false then
				table.insert(Blacklist, Baseparts)
			end
		end
	end
	
	-- Ignore teammates
	for i, Player in pairs(Players:GetPlayers()) do
		if Player.Team == Players.LocalPlayer.Team and Player.Character then
			for i, Baseparts in pairs(Player.Character:GetDescendants()) do
				if Baseparts:IsA("BasePart") then
					table.insert(Blacklist, Baseparts)
				end
			end
		end
	end
	
	local RaycastParameters = RaycastParams.new()
	RaycastParameters.FilterDescendantsInstances = Blacklist
	RaycastParameters.FilterType = Enum.RaycastFilterType.Blacklist
	
	local UnitRay = Camera:ScreenPointToRay(Mouse.X, Mouse.Y)
	
	return workspace:Raycast(UnitRay.Origin, UnitRay.Direction * 100, RaycastParameters)
end

It works, but the raycast is going right through walls

so I changed UnitRay.Origin to the ShootPos on the handle

return workspace:Raycast(Handle.ShootPos.Position, UnitRay.Direction * 100, RaycastParameters)

It works but the bullets go in the wrong directions

so I searched through the DevForum and got nothing

help

#2

what is t

I mean

try Hit.Position

return workspace:Raycast(UnitRay.Origin, Mouse.Hit.Position, RaycastParameters)
#3

the function returns “nil”

I’ve also tried that before and now the bullet doesn’t exist

#4

Can you print out mouse.Hit?

Replace the 1st argy with Handle.ShootPos.Position

return workspace:Raycast(Handle.ShootPos.Position, UnitRay.Direction * 500, RaycastParameters)

ong it works. It doesn’t go through a part now

but the raycast goes a bit down than it supposed to be, it keeps going on the floor instead of the mouse position

full script ( I mean function ) :

local Players = game:GetService("Players")

local Tool = script.Parent
local Handle = Tool:WaitForChild("Handle")
local Mouse = Players.LocalPlayer:GetMouse()
local Character = Players.LocalPlayer.Character
local Camera = game.Workspace.CurrentCamera

local function RaycastMouse()
	local Blacklist = {}

	-- ignore self
	for i, Baseparts in pairs(Character:GetDescendants()) do
		if Baseparts:IsA("BasePart") then
			table.insert(Blacklist, Baseparts)
		end
	end

	-- ignore parts with no collisions
	for i, Baseparts in pairs(game.Workspace:GetDescendants()) do
		if Baseparts:IsA("BasePart") then
			if Baseparts.CanCollide == false then
				table.insert(Blacklist, Baseparts)
			end
		end
	end

	-- Ignore teammates
	for i, Player in pairs(Players:GetPlayers()) do
		if Player.Team == Players.LocalPlayer.Team and Player.Character then
			for i, Baseparts in pairs(Player.Character:GetDescendants()) do
				if Baseparts:IsA("BasePart") then
					table.insert(Blacklist, Baseparts)
				end
			end
		end
	end

	local RaycastParameters = RaycastParams.new()
	RaycastParameters.FilterDescendantsInstances = Blacklist
	RaycastParameters.FilterType = Enum.RaycastFilterType.Blacklist

	local UnitRay = Camera:ScreenPointToRay(Mouse.X, Mouse.Y)

	return workspace:Raycast(Handle.ShootPos.Position, UnitRay.Direction * 500, RaycastParameters)
end

and replace the 2nd argy with Mouse.UnitRay.Direction

then remove the UnitRay variable because I think it’s useless

return workspace:Raycast(Handle.ShootPos.Position, Mouse.UnitRay.Direction * 500, RaycastParameters)

local Players = game:GetService("Players")

local Tool = script.Parent
local Handle = Tool:WaitForChild("Handle")
local Mouse = Players.LocalPlayer:GetMouse()
local Character = Players.LocalPlayer.Character
local Camera = game.Workspace.CurrentCamera

local function RaycastMouse()
	local Blacklist = {}

	-- ignore self
	for i, Baseparts in pairs(Character:GetDescendants()) do
		if Baseparts:IsA("BasePart") then
			table.insert(Blacklist, Baseparts)
		end
	end

	-- ignore parts with no collisions
	for i, Baseparts in pairs(game.Workspace:GetDescendants()) do
		if Baseparts:IsA("BasePart") then
			if Baseparts.CanCollide == false then
				table.insert(Blacklist, Baseparts)
			end
		end
	end

	-- Ignore teammates
	for i, Player in pairs(Players:GetPlayers()) do
		if Player.Team == Players.LocalPlayer.Team and Player.Character then
			for i, Baseparts in pairs(Player.Character:GetDescendants()) do
				if Baseparts:IsA("BasePart") then
					table.insert(Blacklist, Baseparts)
				end
			end
		end
	end

	local RaycastParameters = RaycastParams.new()
	RaycastParameters.FilterDescendantsInstances = Blacklist
	RaycastParameters.FilterType = Enum.RaycastFilterType.Blacklist

	local UnitRay = Camera:ScreenPointToRay(Mouse.X, Mouse.Y)

	return workspace:Raycast(Handle.ShootPos.Position, Mouse.UnitRay.Direction * 500, RaycastParameters)
end

yes

its fixed

after 4 weeks of research

thank you
