Apr 19, 2020 · Variable names are flexible, but cannot be a Lua keyword. For example, you could not have a variable named local. = 1 assigns the value 1 to variable. Variables that are not given an initial value are equal to nil, indicating that they have no value.
`Player:init` does *not* pass a variable named `Player`. The `self` variable is passed implicitly by Lua on the player table created via the Player object, when the `Player()` function is called in `Player.spawn_player`. The two questions have a lot of overlap so I will just describe the Player object functionality in one go. Some Lua background:

Objects will not be equal if the types are different or refer to different objects. Lua provides the logical operators and, or and not. In Lua both nil and the boolean value false represent false in a logical expression.
Lua. From Cheat Engine. Jump to navigation Jump to search. readPointer: In a 64-bit target this equals readQword, in a 32-bit target readInteger(). Not all properties of all classes have been explicitly exposed to lua, but if you know the name of a property of a specific class you can still...
The print function is not required, but will show in the luahistory log which is quite handy. If you are not at all familiar with code, the main confusion here could be the use of the equal sign - there are 2 uses of the = sign, one where you want to set a variable to a particular value: so if you want to set x to 5 it would be x = 5.
If there are no errors, returns the compiled chunk as a function; otherwise, returns nil plus the error message. The environment of the returned function is the global environment. chunkname is used as the chunk name for error messages and debug information.Another word for an upvalue in Lua is an external local variable. When you write a new function in Lua, it can access any of the local variables that have the same scope as it. That function 'closes' over those local variables which is why it's ca...
Insert and search for numbers in a binary tree. When we need to represent sorted data, an array does not make a good data structure. Say we have the array [1, 3, 4, 5], and we add 2 to it so it becomes [1, 3, 4, 5, 2] now we must sort the entire array again!

This is the main reference for the UI Lua runtime in World of Warcraft. Note these are mostly standard Lua functions available in most Lua environments. Arguably could just refer to the Lua.org web site, but a few functions differ in Blizzard's implementation. They are all documented here for consistency and to allow for commentary. The World of Warcraft Lua runtime does not provide all ...

Strict equal (===) * When setting a new function the old one will not be called anymore. 74. * Some of this callbacks are already used for the libmana.lua.

Apr 23, 2013 · The Lua code will be run every time the scene is activated either by the user or a scene or a timer. The Lua code is run before the commands that you included in the scene. If your Lua code ends with this: "return false" then the commands in the scene will not be run. You can also add Lua code to an event by clicking 'Luup event'.

the characters “..” in lua mean concatenate (no that’s not a typo, it’s a real word). Concatenating is when you join two strings together, so if we put together Message1: “Hello” with a space character and Message2: “world” and then concatenate Message3: “!” onto the end you get “Hello world!”.
Why not focus on the things that we are naturally great at, and make those things our competitive advantage so that we can get ahead, rather than get to equal?

When programming in Lua, it is important to understand the different meanings of nil and NULL. Nil is the "unknown type" in the context of Lua whereas null and NULL represent the SQL NULL. The NULL constant is not part of standard Lua and was added by us so the user can do NULL comparisons of result data.
Sets x as the ``seed'' for the pseudo-random generator: equal seeds produce equal sequences of numbers. math.sin math.sin (x) Returns the sine of x (assumed to be in radians). math.sinh math.sinh (x) Returns the hyperbolic sine of x. math.sqrt math.sqrt (x) Returns the square root of x. (You can also use the expression x^0.5 to compute this ...
The return values must be a boolean indicating wether the goal is satisfied, and a float indicating the distance to the goal, i.e.:boolean satisfied, number distance=goalSatisfied(table state)If a distance to the goal is not known, a constant value can be used, but the performance of the algorithm will be worse.

For detailed documentation, please refer to the Lua manual, this is an example: local function tree_insert(tree, x) local lower, equal, greater = split(tree.root, x) if not equal then equal = { x = x, y = math.random(0, 2^31-1), left = nil, right = nil } end tree.root = merge3(lower, equal, greater) end. Note that future versions of Lua extend the Lua 5.1 syntax with the following features; with the exception of the string literals, these are not supported by Luau:
If __le is not defined, lua will use __lt, considering that (a <= b) is equivalent to not (b < a). __concat : concatenation Finally it can have the following fields for unary operators.
If present and equal to false only the values already in the header of the database are returned, that is, the values for the keys version, buckets, bucket_size, header_size, learnings, extra_learnings, classifications and mistakes. If full is equal to true, or not given, the complete statistics is
Feb 15, 2019 · If you are not sure where the game is looking for the file you can either hardcode a path or use ProcessMonitor to check all the system files calls: Conclusion. Lua is a strong and powerful scripting engine and it is used by hundreds of games. Targeting a scripting engine like this will be definitely a good entry point to any game using it.
Lua provides the logical operators and, or and not. In Lua both nil and the boolean value false represent false in a logical expression. Anything that is not false (either nil or false) is true, including 0, which might be surprising coming from some other languages. There are more notes on the implications of this at the end of this page.
If Statement Basics. Lua if statements are pretty simple. The simplest look like this: if boolean_expression_evaluates_true then Now both you and I know that a must either be less, equal or more than b, any other situation is clearly impossible, so it's kind of silly to include that last else...
Beginning Lua Programming (BLP) is a very good book on the subject, especially for people new to Lua or perhaps even to programming. I own this book as well as the "Programming in Lua" (PIL) book by Roberto Ierusalimschy, the latter of which I think has some of the best technical writing I've seen in a computer book and is on par with the likes ...
Do not send large files (>100KB) to the mailing lists, just place a note that further data is available on request. Large files will only annoy a lot of people on the list who are not interested in your specific problem. If required, you will be asked for further data by the persons who really can help you.

Lua also assumes that a <= b is equivalent to not (b < a) which in the presence of NaNs may or may not be what you want - if not, use decnum:compare directly. Uses the C library functions decNumberCompare() and decNumberIsNegative() .
Mar 11, 2016 · Addons in World of Warcraft share a single execution environment. As a result, all Addons have access to the same global variables. If one Addon creates a global variable named "foo", then all other addons can use (or overwrite) that same variable. This allows for some really useful things to happen; the most frequently used tactic that takes advantage of this feature is hooking. Unfortunately ...

Lua threads are not related to operating-system threads. Lua supports coroutines on all systems, even those that do not support threads natively. The expressions a[i] and a[j] denote the same table element if and only if i and j are raw equal (that is, equal without metamethods).
