Lua if else

May 15, 2012 · Else I'll create a function for it but its easier for me to do stuff if there's a built in function. thanks ... Lua quite some table tricks, so maybe I can offer a ... Tutorial scripts. A dissector tutorial script. Download this dissector.lua file for an example Lua script for a protocol dissector. The script is too long to embed in this page, and it's much better to view it in a text editor that supports Lua syntax highlighting, because there are a lot of comments in the script explaining things. Runs a script from a file.The file scriptmust be inside the [Command base directory]/Lua directory,or else the game will not be able to load it.You can make the file point to files within a sub-directory of this,as in 'library/cklib.lua'The file to find will be of the form [Command base directory]/Lua/[script]A file can also be loaded ... While that is true, a lot of users just use Lua for ROBLOX and nothing else, and as a result, they don’t really know what the differences are between ROBLOX Lua and regular Lua. If you understand what Lua is beyond ROBLOX, this makes perfect sense, and ROBLOX Lua is still Lua from a syntax perspective. In Lua, > if 0 then >> print ("true") >> else >> print ("false") >> end true prints "true"! You should use false, or nil in place of 0: > if false then print ("true") else print ("false") end false > if nil then print ("true") else print ("false") end false. Why? The reason for this is historical. Lua did not support boolean types (i.e. true ... If statements are and will always, compare things. They return a bool, which is true or false. If statements are always "if this has happened, then do that" kind of scripts. Here is an example of a door: This tells the door to open if it is closed, and close if it is opened. Pretty simple, right? We can add something else, and it will close if it isnt already after fifteen seconds. It sure would be swell, and we can accomplish this concept in Lua using these things called 'if' statements. In Lua, > if 0 then >> print ("true") >> else >> print ("false") >> end true prints "true"!

Jul 01, 2008 · I have looked around for an answer, but maybe its the oddity of the question that is causing me issues but anyway. Someone told me that it uses up alot more processing power for lua to read multiple if statements and I should try and use elseif instead. Lua is a powerful, efficient, lightweight, embeddable scripting language. It supports procedural programming, object-oriented programming, functional programming, data-driven programming, and data description. Lua combines simple procedural syntax with powerful data description constructs based on associative arrays and extensible semantics. An if statement tests its condition and executes its then-part or its else-part accordingly. The else-part is optional. if a<0 then a = 0 end if a<b then return a else return b end if line > MAXLINES then showpage () line = 0 end When you write nested if s, you can use elseif.

Conditional statements allow you to check to see if something is true or not. They are often used with relational and logical operators.

Edited January 13, 2019 by Reinhold Aug 24, 2019 · I want to ask if lua contains something like switch in c#, php, … swith (a){ case 1: code break case 2: code break case 3: code break } (c#) or if i just must use if a == 1 then code end elseif a == 2 then code end elseif a == 3 then code end In Lua, if, elseif and else use then and end clauses to delimit the conditional code]] j = 45-- == for equality testing if j==45 then print ("yes") end if j==47 then print ("no") end-- ~= for NOT equals if j~=47 then print ("two nose make a yes") end-- chaining with elseif and endif bool Contains(const std::vector<int> &list, int x) { return std::find(list.begin(), list.end(), x) != list.end(); } placing an "else" in the "statement" will split the statement in two, but only by two, with else there is only two possible solutions, so two "sub-statements", if you want it call it that. placing and "elseif" in the "statement" will split the statement in to however many elseif, else and if's there are in the statement. examples: If the Boolean expression evaluates to true, then the if blockof code will be executed, otherwise else blockof code will be executed. Lua programming language assumes any combination of Boolean trueand non-nilvalues as true, and if it is either Boolean falseor nil, then it is assumed as falsevalue. Oct 23, 2009 · Why Lua’s 0 (zero) as a true value makes sense October 23rd, 2009 | English , Lua , Programming When I started to learn about Lua, I found it a little odd that the numeric 0 (zero) value is treated as a true boolean value by the interpreter, which was different from all other programming languages I had worked with. Conditional statements allow you to check to see if something is true or not. They are often used with relational and logical operators. You will be using if, else, and elseif. if An if statement tests a condition: if workspace:FindFirstChild'Hint' == nil then -- if there isn't a hint in workspace Instance.new("Hint", workspace).Text = "Hi!"

False and nil are both considered as false, while everything else is considered as true.
