I’ve been trying to replicate the Classic Rocket Launcher tool but I’m having a hard time doing so. I keep getting this error and for some reason, the rocket teleports under the tool and explodes…
10:19:01.412 Workspace.Rocket Launcher.Rocket:12: invalid argument #2 to 'new' (Vector3 expected, got CFrame) - Server - Rocket:12
10:19:01.413 Stack Begin - Studio
10:19:01.413 Script 'Workspace.Rocket Launcher.Rocket', Line 12 - Studio - Rocket:12
10:19:01.413 Stack End - Studio
This is the local script that sends the position of the mouse when it is clicked:
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 cooldown = false
local UserInputService = game:GetService("UserInputService")
local RemoteEvent = script.Parent:WaitForChild("RemoteEvent")
Tool.Equipped:Connect(function()
UserInputService.MouseIcon = MOUSE_ICON
end)
Tool.Unequipped:Connect(function()
UserInputService.MouseIcon = "rbxassetid://1"
end)
Tool.Activated:Connect(function()
if not cooldown then
cooldown = true
RemoteEvent:FireServer(Player:GetMouse().Hit)
UserInputService.MouseIcon = RELOADING_ICON
task.wait(5)
UserInputService.MouseIcon = MOUSE_ICON
cooldown = false
end
end)
This is the script that creates the rocket and fire’s it off
local tool = script.Parent
local handle = tool.Handle
local remoteEvent = tool:WaitForChild("RemoteEvent")
local rocketSpeed = 200
remoteEvent.OnServerEvent:Connect(function(player, pos)
print(pos)
local rocket = Instance.new("Part")
rocket.Size = Vector3.new(4, 1, 1)
rocket.BrickColor = player.TeamColor
rocket.CFrame = CFrame.new((handle.CFrame * CFrame.new(5, 0, 0)).Position, pos)
rocket.Velocity = rocket.CFrame.LookVector * rocketSpeed
rocket.Parent = workspace.Terrain
local vectorForce = Instance.new("VectorForce")
vectorForce.Enabled = true
vectorForce.Parent = rocket
vectorForce.Name = "Anti-Gravity"
vectorForce.Force = Vector3.new(0, rocket:GetMass() * workspace.Gravity, 0)
rocket.Touched:Connect(function(hit)
if not hit:IsDescendantOf(player.Character) then
local explosion = Instance.new("Explosion")
explosion.Parent = workspace.Terrain
explosion.Position = rocket.Position
rocket:Destroy()
end
end)
end)
Mouse.Hit returns a CFrame, and you need two Vector3’s for the CFrame constructor, so change RemoteEvent:FireServer(Player:GetMouse().Hit) to RemoteEvent:FireServer(Player:GetMouse().Hit.Position) in the local script.
local downForce = -copy:GetMass() * workspace.Gravity
local force = -downForce
local bodyForce = Instance.new("BodyForce")
bodyForce.Parent = copy
bodyForce.Force = Vector3.new(0, force, 0)
copy.Touched:Connect(function(hit)
if not hit:IsDescendantOf(plr.Character) then
local explosion = Instance.new("Explosion")
explosion.Parent = workspace.Terrain
explosion.Position = copy.Position
copy:Destroy()
end
end)
end)
Ii made a rocket mesh and put in repsotrage, if u want the aesthetics just do the same, or else modify the thing until ur happy
Hey uh, for one half of the code you sent me is unformatted and also this doesn’t really help me even though you gave me a script, because I don’t know at all what you changed except for the rocket mesh to fix it.
Yes, I know, but instead of just doing what I asked it would be better if you’ve given me an explanation of what you would’ve done to change it and then given me the script explaining what you changed and how that made it work, because to me you just gave me a script (haven’t tested it) and I don’t even know what you’ve changed to improve it…
I see a lot of people do this on the developer forum, and I can’t improve my scripting skills if all I am given is a script and no written explanation of what I can improve to fix the issue at hand.
And I know we don’t script the exact same way, but it would also be helpful if you kept up with the same variables and didn’t change anything major such as that because now I have to make tweaks for that…
Sorry man, but i have no access to ur game so i made my own rocket launcher rq. But imma explain the script as best as i can.
-- Initialization
local remote = script.Parent.RemoteEvent -- Reference to a RemoteEvent in the parent of the script
local tool = script.Parent -- Reference to the parent of the script (presumably a tool)
local rocketSpeed = 200 -- Speed of the rocket
-- Event Handling
remote.OnServerEvent:Connect(function(plr, pos)
-- Rocket Creation and Launch
local rocket = game.ReplicatedStorage.Rocket -- Reference to the rocket model in ReplicatedStorage
local copy = rocket:Clone() -- Clone the rocket
copy.Parent = workspace -- Set the rocket as a child of the workspace
copy.CFrame = CFrame.new(tool.Start.Position, pos) -- Position the rocket at the tool's "Start" position
copy.Velocity = copy.CFrame.LookVector * rocketSpeed -- Set the velocity of the rocket
-- Gravity Simulation
local downForce = -copy:GetMass() * workspace.Gravity -- Calculate gravitational force
local force = -downForce
local bodyForce = Instance.new("BodyForce") -- Create a BodyForce to simulate gravity
bodyForce.Parent = copy
bodyForce.Force = Vector3.new(0, force, 0) -- Apply the force in the negative Y direction
-- Rocket Collision Handling
copy.Touched:Connect(function(hit)
if not hit:IsDescendantOf(plr.Character) then
-- Create an explosion at the rocket's position
local explosion = Instance.new("Explosion")
explosion.Parent = workspace.Terrain
explosion.Position = copy.Position
explosion.BlastPressure = 100 -- Adjust this value for a stronger force
copy:Destroy() -- Destroy the rocket after the explosion
end
end)
end)
I know understand how it works and everything, but one issue with it is that sometimes it bounces off of a part when a collision is made, and the explosion “flies away” similar to how it did in the video I showed in the post.
(The video with the old script, just showing how the explosion kind of “flies away” with the script you’ve provided me with)
Well, it works for me. U shouldve have things in the part called “Snap” when the rocket collides then it explodes and it unanchors and just blasts yk? and i put blast pressure highter btw i set it to 500k.
so found out that if it contains weld or weld constraint that it can work too!
Also found out where that weird glitch comes from u were talking about, so if u hit urself it bounces of from u so u have to be aimbing forward or use:
else
plr.Character:WaitForChild("Humanoid").Health = 0
local explosion = Instance.new("Explosion")
explosion.Parent = workspace.Terrain
explosion.Position = copy.Position
explosion.BlastPressure = 2000 -- Adjust this value for a stronger force
copy:Destroy()
that kills the player and destroys the rocket
line 25
yeah so update:
i made new changes:
local remote = script.Parent.RemoteEvent
local tool = script.Parent
local rocketSpeed = 200
remote.OnServerEvent:Connect(function(plr, pos)
local rocket = game.ReplicatedStorage.Rocket
local copy = rocket:Clone()
copy.Parent = workspace
copy.CFrame = CFrame.new(tool.Start.Position, pos)
copy.Velocity = copy.CFrame.LookVector * rocketSpeed
local downForce = -copy:GetMass() * workspace.Gravity
local force = -downForce
local bodyForce = Instance.new("BodyForce")
bodyForce.Parent = copy
bodyForce.Force = Vector3.new(0, force, 0)
wait(0.023)
copy.Touched:Connect(function(hit)
local explosion = Instance.new("Explosion")
explosion.Parent = workspace.Terrain
explosion.Position = copy.Position
explosion.BlastPressure = 500000 --Change for stronger force yk
if not hit:IsDescendantOf(plr.Character) then
copy:Destroy()
else
plr.Character:WaitForChild("Humanoid").Health = 0
end
end)
end)
added a wait and added better functionality so it doesnt explode immediatly
