Can't seem to call wrefresh or wborder in lcurses

I'm trying to use lcurses in lua5.3. Creating the window is fine but any attempt to call eg curses.wrefresh(new_win) so it displays fails as calling a nil value. Same with calling new_win:wrefresh(). Frankly the token example in lcurses on github is woefully inadequate.

local function main ()
local stdscr = curses.initscr ()

curses.cbreak ()
curses.echo (false)
curses.nl (false)

stdscr:clear ()

newwin = curses.newwin(10,30,5,5)
newwin:box(0,0)
newwin:mvaddstr(1, 3, "Box Title")
curses.wrefresh(newwin) - fails - nil value
newwin:wrefresh() - also fails nil value


stdscr:refresh ()

local c = stdscr:getch ()
if c < 256 then c = string.char (c) end

curses.endwin ()
end


The odd thing is I can call new\win:box(0,0) but can't call new_win:wborder(0,0,0,0,0,0) - similarly a nil value - which should be identical

Very specific Lua question: is there a Lua equivalent to "pop"ing an element of an "array"?

Context: New to Lua, trying to write a PI controller (as in PID) to run on a Pixhawk 4 flight controller. The final code needs to be small and efficient so it can be run as fast as possible.

In a different language, my approach would be to have an array of fixed size, holding the error at each of the past n steps, and a variable that holds the sum total of that array to act as the integral for the I controller. On every step, I'd pop the first array element to subtract it from the variable, then add my new step error to the array and total, then update the output according to the new total.

But I've been trying to read documentation and it seems like the table.remove() is inefficient if used like this?

My backup plan would be to just have a looping index variable and replace that array element instead of "pop"ing, but I want to know if there's a more effective way to do this.

.lua noscripts MPV

I have it in two locations which I've found both online. i need to run .lua noscripts on MPV using the noscript :https://github.com/gthreepw00d/mpv-iptv



both my locations for noscripts currently are :



C:\\Program Files\\mpv\\portable_config\\noscripts



C:\\Users\\USERNAME\\AppData\\Roaming\\mpv\\Scripts



These are the locations i have seen suggested online:



in my noscripts folders are:

https://github.com/mpv-player/mpv/blob/master/etc/mpv.conf

https://github.com/mpv-player/mpv/blob/master/etc/input.conf

https://github.com/gthreepw00d/mpv-iptv

How to view/edit Balatro source code?

Hello all!

I am fairly new to programming in general but I've been putting a lot of time and effort into learning Lua. I started with aspirations to create a mod for Balatro, and am very confident in the basics of the language. However the next roadblock I've hit is how to actually view the source code for Balatro so that I can read through it and gain an understanding of how the engine and functions work. Is there a specific software I need to use to open these files, and would it be the same software that I would use to code and develop my own mod?

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`

and this is the Local Script:

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



`Bullet.Parent = game.Workspace`
