Attempt to index nil with "Hit"

So,

I’ve been trying to make a sticky bomb that when thrown sticks to players and objects and then explodes, dealing x amount of damage.

Things that I want to achieve:

  • Make the sticky bomb throwable.
  • Make the sticky bomb stick.
  • Allow players to throw the sticky bomb into the air (with a certain force).

How should I go about doing this with a tool?

I tried doing something today so the bomb could get thrown, but I got the error that the mouse was nil. What should I do?

function throwBomb(bombClone, mouse)
	local initialPos = bombHandle.Position
	local targetPos = mouse.Hit.Position
	local distance = (targetPos - initialPos).Magnitude
	
	local travelTime = 2
	local force = distance * Vector3.new(0, workspace.Gravity * 0.5, 0)
	
	bombClone:ApplyImpulse(force * bombClone.AssemblyMass)
end

local MOUSE_ICON = "rbxasset://textures/GunCursor.png" -- Changes the mouse to the GunCursor Icon.
local RELOADING_ICON = "rbxasset://textures/GunWaitCursor.png" -- Changes the mouse icon to the Gun Wait Curso Icon.

local player = game.Players.LocalPlayer

local Tool = script.Parent
local UserInputService = game:GetService("UserInputService")
local activateBombRemote = script.Parent:WaitForChild("ActivateBomb")

Tool.Equipped:Connect(function()
	UserInputService.MouseIcon = MOUSE_ICON
end)

Tool.Unequipped:Connect(function()
	UserInputService.MouseIcon = ""
end)

Tool.Activated:Connect(function()
	local cooldownTime = activateBombRemote:FireServer(player:GetMouse())
	
	repeat task.wait() until cooldownTime == false
	
	UserInputService.MouseIcon = RELOADING_ICON

	UserInputService.MouseIcon = MOUSE_ICON
end)

I reccomend watching this video, then just create a weld between the bomb and whatever it touches

To achieve your result, check out the documents below.
These are essential

Raycasting

Tools

#5

You can’t pass the mouse to the server, it’s not replicated.
Try to pass the Hit instead.

#6

In that case, can’t exploiters change the hit position?

#7

Send the direction of the throw to the server, and cast a raycast (on server) to determine where it lands etc

To get the direction (on client) you can use Mouse.UnitRay.Direction

#8

So would I use the mouse.unitray.direction for the direction parameter in the raycast and then have the origin be the handle’s position?

#9

yes also multiply the direction in the raycast by a number like 100, the number you multiply the direction by would be the distance value, so it would look something like

local distance = 100
local raycastResult = workspace:Raycast(origin, direction * distance, raycastParams)
local position = raycastResult and raycastResult.Position
