What does _ do in Lua?
22. Usually used as a throwaway variable. It has no special “real” meaning, but is used to indicate that the indicated value is not important. The variable consisting only of an underscore “_” is commonly used as a placeholder when you want to ignore the variable… Read More here (in the naming part).

What are tables in Lua?
Tables are the only data structure available in Lua that helps us create different types like arrays and dictionaries. Lua uses associative arrays and they can be indexed not only with numbers but also with strings, except nil. The tables do not have a fixed size and can grow depending on our needs.
Are there lists in Lua?
Other types of lists, such as doubly linked lists or circular lists, are also easily implemented. However, you rarely need such structures in Lua, because there is usually a simpler way to represent your data without using lists.
Does Lua have a main function?
Being an extension language, Lua has no notion of a “main” program: it only works embedded in a host client, called an embed program or simply host. This host program can call functions to execute a piece of Lua code, can write and read Lua variables, and can register C functions to be called by Lua code.
Are tables arrays?
Table arrays store tabular or column-oriented data, such as columns in a text file or spreadsheet. Tables store each column-oriented piece of data in a variable. Table variables can have different data types and sizes as long as all variables have the same number of rows.
What does the Lua do in the address field?
That code also seems to imply that the Lua running on the address field should have access to two local variables, memrec, which would contain a Lua MemoryRecord for the current cheat, and address, which would contain the base address of the current cheat. (Really useful for relative addressing when you have traps organized in a tree.)
How is Lua used in tmemrecoffset Cheat Engine?
TMemrecOffset seems to use a technique where it parses it once when the string is set, and then if it turns out to be valid Lua, it saves the function returned by loadstring and calls it again later when the address needs to be resolved. The Lua is parsed once and then reused.
How to run Lua for Cheat Table entries?
I found this section of code in MemoryRecordUnit.pas that seems to handle Lua execution for cheat table entries.
What happens if I disabled the hook in Lua?
With the hook in luasymbols.lua disabled, none of my Lua cheats work anymore. However, if I prepend them with $, the code in getAddressFromName takes over and they start working. But that code also doesn’t provide access to address or memrec values, so it’s not much more useful.
What is Lua syntax?
Lua combines a simple procedural syntax with powerful data description constructs based on associative arrays and extensible semantics. The host program can call functions to execute a piece of Lua code, can write and read Lua variables, and can register C functions to be called by Lua code.
What does == mean in Lua?
Lua provides the following relational operators: < > <= >= == ~= All of these operators always return true or false. The == operator checks for equality; the operator ~= is the negation of equality. We can apply both operators to any two values. If the values have different types, Lua considers them different values.
What do 3 dots mean in Lua?
The three dots ( ) in the parameter list indicate that the function has a variable number of arguments. When this function is called, all of its arguments are collected into a single table, which is accessed by the function as a hidden parameter named arg .
Is the function a Lua?
It means that, in Lua, a function is a value with the same rights as conventional values like numbers and strings. Functions can be stored in variables (both global and local) and in tables, passed as arguments, and returned by other functions.
Is Lua faster than Python?
Against Lua, Python is slow on speed. It is faster in speed compared to Python. 07. Usually used for scripting application and also as a standalone program.
Is Lua easy to learn?
What is Lua? Lua is a popular scripting and programming language (learn more). It’s lightweight and easy to learn, nature means it’s built in for use in many programs; Roblox is an example.
Is Lua like Python?
Lua is a high-level, general-purpose scripting programming language that is the best choice for game developers. Like Python, it is an open source programming language that is based on the C programming language. It is an extensible and lightweight programming language.
Is Lua a dead language?
While Lua is still used quite frequently in games and web services, it performed poorly in terms of community engagement and job market prospects. That said, despite her age, Lua’s growth has plateaued rather than slowed, meaning that while she’s not popular, she’s not dying either.
What is Lua Pcall?
pcall stands for “protected call”. It is used to add error handling to functions. pcall works similar to try-catch in other languages. The advantage of pcall is that all script execution is not interrupted if errors occur in functions called with pcall.
How do you expect in Lua?
lua await function code example
- function wait (seconds) local start = os.
- wait(5) — Waits 5 seconds, then prints “Hello world!” print(“Hello world!”)
- local clock = function os.clock sleep(n) — seconds local t0 = clock() while clock() – t0 <= n do end end.
