Sol + Enet

I want to call functions in the Lua state when a packet is received etc., but enet is currently on a separate thread to not hang the main thread. However, I have noticed a lot of memory problems that come from this. I've tried using mutex but nothing has been alleviated. Any guidance or perhaps different networking libraries I should consider?

My "Bullet" doesn't deal any damage on collision.

So im trying to make a gun/blunderbuss in roblox and everything works just fine apart from the damage, i've tried a lot of things to fix it but nothing worked, someone help me Please.


This is the Script:

`local tool = noscript.Parent`

`local bulletsFolder = noscript.Parent:FindFirstChild("Bullets")`



`function createBullet(bulletPosition)`

`local Bullet = Instance.New("Part", bulletsFolder)`

`Bullet.CFrame = CFrame.new(bulletPosition)`

[`Bullet.Name`](http://Bullet.Name) `= "Bullet"`

`Bullet.Size = Vector3.new(0.1,0.1,0.1)`

`Bullet.BrickColor = BrickColor.new("Black metallic")`

`Bullet.Shape = Enum.PartType.Ball`

`Bullet.CanCollide = true`

`Bullet.Transparency = 0`

`Bullet.BottomSurface = Enum.SurfaceType.Smooth`

`Bullet.TopSurface = Enum.SurfaceType.Smooth`

`Bullet.Anchored = true`



`game.Debris:AddItem(Bullet, 10)`





`end`



`-- raycasting`

`noscript.Parent.Shoot.OnServerEvent:Connect(function(player, mousePosition)`

`local raycastParams = RaycastParams.new()`

`raycastParams.FilterDescendantsInstances = {player.Character}`

`raycastParams.FilterType = Enum.RaycastFilterType.Exclude`



`local raycastResult = workspace:Raycast(tool.Handle.Barrel.Position,(mousePosition - tool.Handle.Barrel.Position) * 300, raycastParams)`



`if raycastResult.Position then`

`createBullet(raycastResult.Position)`

`end`



`if raycastResult then`

`local raycastInstance = raycastResult.Instance`

`local model = raycastInstance:FindFirstAncestorOfClass("Model")`



`if model then`

`if model:FindFirstChild("Humanoid") then`

`if` [`raycastInstance.Name`](http://raycastInstance.Name) `=="Head" then`

`model:FindFirstChild("Humanoid"):TakeDamage(40)`

`else`

`model:FindFirstChild("Humanoid"):TakeDamage(20)`

`end`

`end`

`end`

`end`



`end)`

and this is the Local Script:

`local userInputService = game:GetService("UserInputService") --UIS`



`local player = game.Players.LocalPlayer --player`

`local mouse = player:GetMouse() -- mouse`



`local tool = noscript.Parent`

`local debounce = false`

`ammo = 1`

`MaxAmmo -= 1`

`player.PlayerGui.AmmoGui.Frame.TextLabel.Text = "Ammo: "..ammo.."/"..MaxAmmo`

`reloading = false`

`end`

`end`

`Bullet.CanCollide = true`

`Bullet.Transparency = 0`

`Bullet.BottomSurface = Enum.SurfaceType.Smooth`

`Bullet.TopSurface = Enum.SurfaceType.Smooth`

`Bullet.Shape = Enum.PartType.Ball`



`local bodyVelocity = Instance.new("BodyVelocity")`

`bodyVelocity.MaxForce = Vector3.new(math.huge, math.huge, math.huge)`

`bodyVelocity.P = math.huge`

`bodyVelocity.Velocity = mouse.UnitRay.Direction * 300`



`Bullet.Parent = game.Workspace`

`bodyVelocity.Parent = Bullet`



`game.Debris:AddItem(Bullet, 3)`

`end`



`-- Shooting`

`tool.Activated:Connect(function()`

`if debounce == false and ammo > 0 and reloading == false then`

`debounce = true`

LuaRT - Windows programming framework

https://preview.redd.it/9e1upzpdg8pb1.png?width=494&format=png&auto=webp&s=49c295d5e8d9dcd3bf974b9afafc14d3fc6d21da

Lua^(rt) is a free, open-source programming framework built on Lua, designed for Windows application development and released under the MIT license I just released Lua^(rt) 1.9.5, and I think it's time to give you an update on the current status of the project.

What is Lua^(rt)
Lua^(rt) extends Lua -a language valued for its beginner-friendly syntax and simplicity- to create console and desktop applications on Windows. It includes runtime modules and tools to make development accessible for newcomers while supporting complex tasks with minimal effort.

Key Features

Beginner-Friendly: Lua’s straightforward syntax makes Lua^(rt) approachable for novices, while still enabling complex tasks—like crafting GUIs or handling web requests—with concise code.
Lightweight Runtime: The Lua^(rt) runtime is compact and self-contained, relying on no external libraries, ensuring minimal overhead and easy deployment.
Object-Oriented Programming: Lua^(rt) enhances Lua with robust OOP support, including multilevel inheritance, mixins, constructors, destructors, properties, and more, for structured and reusable code.
Asynchronous Programming: Lua^(rt) includes a Taskobject for asynchronous operations, supporting async/await/after paradigms to simplify non-blocking code (e.g., running tasks in the background or scheduling delayed actions).
Batteries Included: Lua^(rt) contains lots of modules to cover most of today’s programming tasks, such as: json data parsing, audio playing and recording, clipboard access, Windows registry management, process control, compression, sqlite for database operations, C FFI module to call C functions from your Lua noscripts, and more ...
Enhanced UI Module: The ui module supports modern Windows features:
Theme Support: Adapts to Windows light/dark themes.
HighDPI support
WebView: Embeds WebView2 for displaying web content, and interact with it from Lua
Hardware-accelerated Direct2D rendering with the Canvaswidget
Bundled Development Tools: Lua^(rt) comes with its own suite of tools:
Lua^(rt) Studio IDE: A dedicated environment for writing and debugging Lua^(rt) noscripts.
RTBuilder: A RAD (Rapid Application Development) tool for visually designing GUI applications.
rtc: A compiler to generate standalone executables with embedded content, simplifying distribution.
Documentation: A thorough guide (over 1,000 pages) covers modules, examples, and tutorials,...

Community Resources: A forum at https://community.luart.org provides a space for support and discussion, as well as a Discord server

Purpose and Use

Lua^(rt) leverages Lua’s ease of use and versatility for Windows programming, enhanced by modern features and development tools.

I built this framework to propose a coherent Lua ecosystem for Windows operating systems, aiming to simplify Windows development. It’s suited for beginners building their first apps or experienced users tackling advanced projects, and it’s open to feedback or contributions.

For more details, the official website is a good starting point. I’d be interested in hearing from anyone who tries it or has questions.

Regards,

Samir

can someone can answer my question ? :/
