"if then" Statements

--[[
Here is a something you will definitely use alot: "if then" statements

"if then" statements are script lines with conditions, if the conditions pass, it does X

if not, it will either do nothing or do Y

Here is a basic example of one:
]]

if 3 > 2 then
    print("Complete!")
end
--[[
As you can see, this is an example of an "if then" statement, What this does is check if 2 is
higher than 3

You will notice how the above uses a "greater than" symbol, These are a list of operators that
an 'if then' statement will use:

>  | Greater than
<  | Lesser than
== | Equal to
~= | not equal to
>= | Greater than or is equal to
<= | Lesser than or is equal to

These operators are commonly used for integer or float values, But, You can use them for object values
or other values as well (mainly == and ~=)

There are also another thing called "elseif"

This is a secondary conditonal if the first one fails

Meaning that if the first conditional fails, it checks if the second conditional true, and then does
something else

Anyways, here is a somewhat more 'complex' example of an "if then" statement
]]

if 125 > 500 then --Checks if 125 is higher than 500
    print("Success") --If yes, then print "Success"
elseif 325 < 200 then --If the conditions above isnt met, then check if this conditions work
    print("Success 2") --If the above succeeds, then print "Success 2"
else --If all the conditions above fail, do this instead
    print("Failure") --prints "Failure"
end --This ends the statement

--[[
Lets translate the above into sudo-code (aka somewhat english)

Translated:

If 125 is higher than 500, then make a print with the value "Success"
But if the above is false, then check if 325 is lower than 200, if yes, then
make a print with the value "Success 2", If both of these conditions arent met,
then make a print with the value of "Failure"

^^^^^Make sure you speak your code as sudo-code when your experiencing a bug or issue

it helps alot

----------------------------

These statements can have multiple conditionals as well

Example:
]]

if 5 > 2 and 5 < 10 then
    print("Success")
end

--[[
By adding "and" to a conditional, it will add an another condition for the statement
which makes the conditional require both conditions to be true for it to pass

However, if you want the code to have two seperate conditions and only one of them to pass to get
the same result, you can add an "or"
]]

if 4 > 5 or 4 > 2 then
    print("Success")
end

--[[
Adding an "or" will add a secondary condition, if the first conditon is a fail, then it checks
if the second condition is met, if yes, then print "Success"

And if you are wondering, You can have both of these in the same conditional like this:
]]

if 3 < 8 and 3 > 2 or 5 > 2 then
    print("Success")
end

--And you can also have an another "if then" statement as well

if 2 > 1 then
    print("Part 1")
    if 5 > 2 then
        print("Part 2")
        if 13 > 9 then
            print("Part 3")
        end
    end
end

--[[
And assuming you have this question, this is how an "if then" statement would work:

if (condition 1) or (condition 2) then

Lets move into something more exciting, Variables.

Variables can be added into "if then" statements

So you can do stuff like this:
]]

val1 = 12
val2 = 9

if val1 > val2 then --12 is larger than 9, so it passes
    val1 -= 5 --Reduces the value in val1 by 5, so now val1's new value is 7
    if val1 > val2 then --Checks if val1 is above val2, But since val1's new value is 5, it doesnt pass
        print("End")
    end
end

now that should be "if then" statements completed i think.
