I am getting an error in my currency script in Roblox studio

end)
if savedData ~= nil then
curreny.Value = savedData
print("Data loaded")
else
currency.Value = 10 -- amount to a new player
print("New player to the game")

It is giving me this error at line 3:

I am trying to read the following stream:
127.0.0.1:6379> xrevrange driver:70 + - count 1
1) 1) "1656531417451-0"
2) 1) "field1"
2) "value1"
3) "isbusy"
4) "true"
How can I read this stream in Lua script and reflect the field isbusy from the stream into the the local Lua variable is_busy?
I could not get my head around Lua collections.
local stream = KEYS[1]
local is_busy = false
local messages = redis.call("XREVRANGE", stream, "+", "-", "COUNT", "1")
for _, message in ipairs(messages) do
end
You need to parse the nested structure:
local id
for _, message in ipairs(messages) do
for i, sub_msg in ipairs(message) do
if i == 1 then
id = sub_msg
else
-- parse attributes
local i = 1
while i < #sub_msg do
local k = sub_msg[i]
local v = sub_msg[i + 1]
if k == "isbusy" then
is_busy = v
end
i = i + 2
end
end
end
end
I am trying to create a maze generation script using the module listed below. I'm having this strange problem were the grid variable has a value, but when return grid is called, it returns and empty table? Here is the code to the module script.

Below is the piece of code I'm having diffuculty with.
function Maze.Grid() -- Allows other scripts to get the grid but not modify it
return grid
end
I have tested printing the grid variable and it's not {} but when I call the function in the script below, I always get {}! I have no idea why this is.
Is this a bug in roblox or am I being stupid?
local ServerScriptService = game:GetService("ServerScriptService")
local Maze = require(ServerScriptService:WaitForChild("Maze"))
local latestX = 0
local latestZ = 0
function CreatePath(cell)
local nextCell = cell:RandomNextCell(false)
if nextCell then -- We have a cell next to the current one
print("Joining cells:",cell,nextCell)
cell:Join(nextCell)
cell.Visited = true
cell:Render()
wait(.01)
CreatePath(nextCell)
else -- It must be the end of the maze
print("Path generated!")
print("Maze end: ".. cell.Model.Name)
cell.Base.Color = Color3.new(1,0,0)
end
end
function GenerateMaze()
local cell = Maze.new(latestX + 1,latestZ + 1) -- Create a new cell
cell:Render() -- Render it
print("Created cell")
latestZ += 1
if latestZ > Maze.Size then -- It has exceeded the max size, move on to a new row
latestX += 1
latestZ = 0
end
if #Maze.Grid() < Maze.Size ^ 2 then
wait(.01)
GenerateMaze()
else
print("Grid completed, generating path...")
CreatePath(Maze.GetCell(1,1))
end
end
GenerateMaze()
You are returning a cached value, or well i don't find out other reason.
You may do (and it's not editable):
function Maze.Grid(i, l)
local passed = 1
local response = {}
for index, v in pairs(grid) do
response[index] = i and passed >= i and l and passed <= l and v or not (i or l) and v
-- basically get more than `i` if it, and minor than `l` if it passed
i = i + 1
end
return response
end
It should work, I don't tested it sorry.
I don't know what is wrong with my code, and I don't know what thie error message I got means. I just started using Csound with Cabbage, and coding in general.
I'm trying to ude 1 slider to set the values of multiple variables. I used the slider to set a value for 1 variable, and used some if-then-else statements to set values for other variables.
if kV0 == 1 then kV = 1, kVA = 0, kVB = 0, kV1 = kV2 = kV3 = kV4 = 0
I expect kV to be set to 1 and all other variables to be set to 0 when kV0 is equal to 1. I keep getting this message:
error: syntax error, unexpected T_IDENT, expecting NEWLINE (token "kV")
line 69:
if kV0 == 1 then kV
Parsing failed due to invalid input!
Code like this isn't valid Csound code and you will need to separate the statements onto separate lines, like so:
if kV0 == 1 then
kV = 1
kVA = 0
kVB = 0
kV1 = 0
kV2 = 0
kV3 = 0
kV4 = 0
endif
I have already been searched solution and can't get the right solution yet.

ClientTableAdapter.Update(DataDataSet.Client)
Error is occurs when ClientTableAdapter Update.
This error occurs for some client only.
I already check datatype of database and table adapter's datatype and all datatype are same.
My input value datatype and table adapter's datatype are same.
This error occurs even I command all line of update code (.ClientName to last line) but this error still occurs.WTF
Most answers say this is a single quote problem but In my case, There is no single quote.
All data types are same and input values are the same with datatype.
** Updated**
This error still occurs even I do like=>
ObjDRow = DataDataSet.Client.Rows.Find(strClientNo)
ObjDRow.EndEdit()
ClientTableAdapter.Update(DataDataSet.Client)
There is nothing change just select and update.
But if I remove ObjDRow.EndEdit().All are fine. There is no error.
Can anyone on here help me on decrypting the SSL encryption that protects this LUA script linked at the end of this topic? Basically they are encoded with Base64 then SSL, but I have no idea how to do the SSL portion. They are used with a program called Bot of Legends, and someone told me that it is possible to break the encryption by dumping the decryption function of said program and using that to get the SSL key, but I have no clue where to even start on that. Basically these scripts work by connecting to an authentication server that is coded into the script, and I have gotten a few on my own by sniffing the traffic to their auth server from network packets to get their server link and essentially created my own auth server with Apache, then redirected the network traffic that goes to their server to my own from the script to get the script validated response. For some scripts that have stronger encryption, its not that easy and I would have to get to the source code to remove the coding that runs the auth server checks. Up until a few days ago I had no knowledge on how lua coding worked and how to even compute how auth server checks could be even possible for coding in a simple text file due to lua obfuscation. So bear with me, I would like if someone can chime in and give me an idea on what I can do.
Regards,
Chris

This code is by Extreme Coders (https://reverseengineering.stackexchange.com/users/1413/extreme-coders)
how to use it , u need to get lua52.exe
save the code into a text file and name it ssl.lua (for example)
now run cmd and type lua52 ssl yourscript.lua decryptedscript.lua
it will run and decrypt it.
