Classic roblox rocket launcher kills you

ChiefDarx · June 6, 2020, 1:55am

Make it so the classic roblox rocket launcher does not kill yourself.
It kills other players including the local player.
I have tried using if statements for when the rocket is shot it will make you immune but that did not work.

I’m curious if there is a wiki post on this because I cannot figure this out and idk what the issue is. I have been playing around with the classic roblox rocket launcher for the past few hours.

Can you give us the code for the rocket launcher? old ROBLOX tools are prone to breaking and having the code would help people unlegacy it

Im sorry I forgot to send the code lol.

i figured it out! Do not worry.

RamJoT · June 6, 2020, 12:48pm

Would you care to share your discovery?
Perhaps its in the code your added but its is not obvious what you may have changed.
If you did that please edit it and indicate where you changed it.

Blafert · January 14, 2022, 9:09pm

Can you please enlighten everyone how you did it?

cohen30 · July 11, 2024, 4:00am

Dude can you tell us how to do it don’t just disappear!

TyK214 · August 20, 2024, 5:20am

nah man he just left… i really needed this solution

KillingEveryoneRC · September 4, 2024, 3:58pm

Hey, I have found a solution. First of all go to Server Script called “Server” and change the code to the one below. Problem was that “creator” value was receiving nil instead of the actual player name.

-----------------
--| Constants |--
-----------------

local GRAVITY_ACCELERATION = workspace.Gravity

local RELOAD_TIME = 3 -- Seconds until tool can be used again
local ROCKET_SPEED = 90 -- Speed of the projectile

local MISSILE_MESH_ID = 'http://www.roblox.com/asset/?id=2251534'
local MISSILE_MESH_SCALE = Vector3.new(0.35, 0.35, 0.25)
local ROCKET_PART_SIZE = Vector3.new(1.2, 1.2, 3.27)

-----------------
--| Variables |--

local DebrisService = game:GetService('Debris')
local PlayersService = game:GetService('Players')

local MyPlayer

local Tool = script.Parent
local ToolHandle = Tool:WaitForChild("Handle")

local MouseLoc = Tool:WaitForChild("MouseLoc",10)

local RocketScript = script:WaitForChild('Rocket')
local SwooshSound = script:WaitForChild('Swoosh')
local BoomSound = script:WaitForChild('Boom')

local Rocket = nil

function OnEquipped()
	MyPlayer = PlayersService:GetPlayerFromCharacter(Tool.Parent)

	Rocket = Instance.new('Part') do
		-- Set up the rocket part
		Rocket.Name = 'Rocket'
		Rocket.FormFactor = Enum.FormFactor.Custom --NOTE: This must be done before changing Size
		Rocket.Size = ROCKET_PART_SIZE
		Rocket.CanCollide = false

		-- Add the mesh
		local mesh = Instance.new('SpecialMesh', Rocket)
		mesh.MeshId = MISSILE_MESH_ID
		mesh.Scale = MISSILE_MESH_SCALE

		-- Add fire
		local fire = Instance.new('Fire', Rocket)
		fire.Heat = 5
		fire.Size = 2

		-- Add a force to counteract gravity
		local bodyForce = Instance.new('BodyForce', Rocket)
		bodyForce.Name = 'Antigravity'
		bodyForce.Force = Vector3.new(0, Rocket:GetMass() * GRAVITY_ACCELERATION, 0)

		-- Clone the sounds and set Boom to PlayOnRemove
		local swooshSoundClone = SwooshSound:Clone()
		swooshSoundClone.Parent = Rocket
		local boomSoundClone = BoomSound:Clone()
		boomSoundClone.PlayOnRemove = true
		boomSoundClone.Parent = Rocket

		-- Attach creator tags to the rocket early on
		local creatorTag = Instance.new('ObjectValue', Rocket)
		creatorTag.Value = MyPlayer
		creatorTag.Name = 'creator' --NOTE: Must be called 'creator' for website stats
		local iconTag = Instance.new('StringValue', creatorTag)
		iconTag.Value = Tool.TextureId
		iconTag.Name = 'icon'

		-- Finally, clone the rocket script and enable it
		local rocketScriptClone = RocketScript:Clone()
		rocketScriptClone.Parent = Rocket
		rocketScriptClone.Disabled = false
	end
end

-----------------

local function OnActivated()
	local myModel = MyPlayer.Character
	if Tool.Enabled and myModel and myModel:FindFirstChildOfClass("Humanoid") and myModel.Humanoid.Health > 0 then
		Tool.Enabled = false
		local Pos = MouseLoc:InvokeClient(MyPlayer)
		-- Create a clone of Rocket and set its color
		local rocketClone = Rocket:Clone()
		DebrisService:AddItem(rocketClone, 30)
		rocketClone.BrickColor = MyPlayer.TeamColor

		-- Position the rocket clone and launch!
		local spawnPosition = (ToolHandle.CFrame * CFrame.new(5, 0, 0)).p

As well if you want the rocket not only to ignore the character who launched the rocket, but as well not damage him, go to the disabled Server Script called “Rocket” (it is inside the “Server” script) and change

player ~= myPlayer

in the line 71 to:

player == myPlayer
