I’m trying to make my fighter jet shoot bullets that will show to every player but when I send a remote event to the server, it doesn’t work.

Shoot Client:

local RunService = game:GetService("RunService")

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Bullet = ReplicatedStorage:WaitForChild("Bullet")

local player = game.Players.LocalPlayer
local mouse = player:GetMouse()

local model = script.Parent
local VehicleSeat = model:WaitForChild("VehicleSeat")
local GunPart = model:WaitForChild("GunPart")

local cooldown = 0.1
local currentTime = cooldown

local connection

local function StopFiring()
	if connection then
		connection:Disconnect()
		connection = nil
	end
end

local function FireGun()
	StopFiring()
	
	connection = RunService.Heartbeat:Connect(function()
		if VehicleSeat.Occupant then
			local result = game.Players:GetPlayerFromCharacter(VehicleSeat.Occupant.Parent)

			if result and tick() - currentTime >= cooldown then
				currentTime = tick()
				script.ShootGun:FireServer()

			elseif not result then
				StopFiring()
			end
		else
			StopFiring()
		end
	end)
end

mouse.Button1Down:Connect(function()
	if VehicleSeat.Occupant then
		local result = game.Players:GetPlayerFromCharacter(VehicleSeat.Occupant.Parent)

		if result then
			FireGun()
		end
	end
end)

mouse.Button1Up:Connect(function()
	if VehicleSeat.Occupant then
		local result = game.Players:GetPlayerFromCharacter(VehicleSeat.Occupant.Parent)

		if result then
			StopFiring()
		end
	end
end)

local launchPower = 8000

local function ShootGun()
	local newBullet = Bullet:Clone()
	newBullet.CFrame = GunPart.CFrame
	newBullet.Parent = workspace
	
	newBullet:ApplyImpulse(newBullet.CFrame.LookVector * launchPower)
	game:GetService("Debris"):AddItem(newBullet, 8)
end

script:WaitForChild("ShootGun").OnClientEvent:Connect(function()
	ShootGun()
end)

Server:

script.Parent.ShootGun.OnServerEvent:Connect(function(player)
	script.Parent.ShootGun:FireAllClients()
end)

Bullet Client:

local part = script.Parent

part.Touched:Connect(function(hit)
	local speed = (part.AssemblyLinearVelocity - hit.AssemblyLinearVelocity).Magnitude
	
	if speed >= 100 then
		script.BreakPart:FireServer(hit) -- doesn't fire
	end
end)

Break Part Server:

local function BreakOthers(part)
	for i,v in ipairs(part:GetChildren()) do
		if v:IsA("Attachment") then
			v:Destroy()
		end
	end
end

script.Parent.BreakPart.OnServerEvent:Connect(function(player, part)
        print("test") ---- nothing

	if part then
		part:BreakJoints()
		BreakOthers(part)
	end
end)

Put a print() before the event gets fired.

Also, 100 AssemblyLinearVelocity is extremely fast, and you might not be reaching that speed.

#3

I did and it printed. It only fires if I create the bullet in a server script but I want it to be smooth for all players.

#4

So does it work but it’s not smooth, or what? I’m so confused.

#5

This isn’t really a solution, but using fast cast will make this 10x easier. You don’t need to fire an event to the server and fire it back.

#6

The remote event called “BreakPart” won’t fire even though speed is above 100 and it also prints on the client.

#7

Yes but FastCast isn’t very good for projectile bouncing and I only need to shoot a sphere.

#8 
local speed = (part.AssemblyLinearVelocity - hit.AssemblyLinearVelocity).Magnitude

That won’t work, I just noticed.

You can just get one part’s velocity and that would be the speed, why are you getting the magnitude of two parts?

#9

I want to break the parts if the bullet hits at a certain speed so if the hit part is moving and the part is moving, I have to check both.

local part = script.Parent

part.Touched:Connect(function(hit)
	local speed = (part.AssemblyLinearVelocity - hit.AssemblyLinearVelocity).Magnitude
	
	if speed >= 100 then
		script.BreakPart:FireServer(hit) <---
	end
end)

I fixed it by moving the BreakPart server script into server script service.
