Lua symbol for does not equal code#

We use while loops to run a block of code until the while loop condition becomes false. We use for loops to iterate or run a piece of code on a list. Loops use the for and while language keywords. Here weРІР‚в„ўre testing if a player has a weapon and then running its shoot() function, otherwise we execute the punch() function of the playerРІР‚в„ўs hand.

local someNumber, someNil = 5, nil Condition statementsР”Р„n if-then-else statement defines a condition for a block of code to execute.Р”В®xample: local playerHasWeapon = player.weapon ~= nil When using multiple variables, you must assign a value for each one. You can also assign multiple variables in a single statement.Р”В®xample: local someNumber, someWord = 5, 'hello' You assign a value to a variable by using the = symbol. You can add multiple line comments by starting with РІР‚вЂњ] Lua will not execute anything within the comment. To add a comment in Lua you can use - symbols. Code commentsР”В¬ommenting your code is good for explaining the purpose of a block of code. The or operator is a bit similar to the and keyword except either expression can be true. This example shows that the someNumberIsInRange variable is true when a is greater than zero and less than 100. Local someNumberIsInRange = aGreaterThanZero and aLessThanB To test if a variable is less than another, youРІР‚в„ўll use the 0 To test if a variable is greater than another, youРІР‚в„ўll use the > operator or >= operator. To test if a variable does NOT equal another, youРІР‚в„ўll use the ~= operator. To test if a variable equals another, youРІР‚в„ўll use the = operator. You will get an error if itРІР‚в„ўs used with non-numeric values.Р”В®xample of code that will fail: local x = 10 These mathematical operators only work with variables holding numeric values. There are mathematical operators for addition, subtraction, multiplication, and division. Operators allow us to define code that changes a variableРІР‚в„ўs value. To avoid any confusing issues or bugs in your code, itРІР‚в„ўs always best to declare your variables with local. In this instance, the multiplier variable becomes a global by defining it without the local keyword.Р”Р„dding this to the end of the script executes just fine. Mis-using global variables may lead to confusing behavior in your script. It is important to carefully use global variables since any other script can access them. Variables in a global scope exist until the entire program finishes. Within the function multiplyByFive(), the multiplier variable exists until the function finishes and does not exist outside of it.Р”Р„dding this to the end of the script would fail. In this example, the variable РІР‚ВaРІР‚в„ў exists in memory until the script finishes. If this doesnРІР‚в„ўt happen then our programs will use up all the available memory and eventually crash your computer or device. Once the script finishes, these variables get cleaned up by releasing the memory used. Variables with a local scope only exist until the function or script finishes. Scopes help organize your variables and help to control allocated memory. You can have variables in a local or global scope. ScopesР”Р„ scope determines how long a variable exists in memory while the script is running. The best way to think of nil is that the value does not exist. You might think this is zero but itРІР‚в„ўs not. TypesР”Р„ variable uses the nil type when it should have no value. Dynamic typing means that a variable can store any type of data. You can of course create your own object and add a script for it using the same steps.
